It was not Guru to tell you that you forgot to remove the menu! that tilings were hard to understand, but the documentation just SetMenuStrip takes a window pointer and a menu structure doesn't have many examples. It would have been nice if the pointer as arguments. Here is a simple example of code diat opens window example shown in the ROM Kernel manual had been a window and attaches a menu to it: repeated with an example menu! To understand and use menus,

It seemed that Menu, Menultem, and IntuiText structures could be SetMenuStrip(Window, MyMenu)? setup with default values making tilings simpler. ClearMenuStrip(Window)? /* Remove Menu */ Since I am a lazy person, (a fact my wife will verify!) I decided to write a program that would automate the job. Looking at the CloseWindow(Window); /* close window */ examples and instructions in Chapter 6 of the Intuition Manual, I realizedHi Quality Version Available on AMIGALAND.COM that much ol the menu building process could be calcu­ The structure pointed lated very simply. For example, menus could be placed on a out by the external pointer window based on the width of the title. The width is in pixels which MyMenu is the one built by is easily calculated. The width of the menu items couid also be the MenuBuilder! This calculated using the longest item as die base width for the whole means that code similar to menu. Many other options and parameters could be preset to the above just has to be constants in most cases. I wanted a simple text menu (no graphics) linked again to use updated with support for key stroke equivalents.

Close the requester and bring up the Fill Type requester by clicking the Fill Tool with the right mouse button. Click the up-and-down gradient box then close. Now pick the blue as your foreground color, the Fill as your tool, and fill the box you just made. Sec how the two colors shade from top to bottom and are dithered in the center? Now pick the Brush Selector, and using the right button on the mouse pick up your name as a brush. Make sure that your background color is red so that you will pick up only the letters. Move your name so that it is positioned over the rectangle but do not stamp it down just yet. Pick red as your foreground color and hit ‘o’ on the keyboard. This will outline your name in the current foreground color (red) approximately one pixel thick. Hit ‘o' two more times. Now you have a nice contrasting outline around your name. Center your name over the rectangle and stamp it down. Centering items on a page can be made very simple with the Coordinates feature which I mentioned earlier. I always turn this on before I begin any project. When you pick up something as a brush ttyr to draw the Brush Selector lines evenly around the object. In this case, if the letters of your name are centered within the brush you cut out then you can stamp them down (reading the coordinates on Hi Quality Version Available on AMIGALAND.COMthe Title Bar) in the center of the page. In this example, the screen is 704 pixels wide so we know that tlte center is around 351 (pixels read 0-703) pixels! This is horizontal centering, If I am centering a single object or line of text vertically on a page, I like to keep it just a little above die actual center. Tills seems to be more pleasing to the eye. Try picking up the entire rectangle with your name inside as a brush (Brush Selector-right mouse button). Leave about one quarter of an inch around all four sides of the rectangle (for centering) when you cut the brush. Now stamp diis centered brush at 351 X 260 (slightly higher than the middle-240). Before you do anything else, click 011 Undo. All of your hard work will disappear. We do this because we don’t want to draw this brush yet. we just want to tell the Move requester where we want the brush to end up. Even though we c an't see the image anymore, die Move requester remembers the brush and where we want it. Now open the Move requester (Move under the Anim menu or “shift-m”. Click "Brush” and “Cycle” to de-select them. Next do the following diings: 1. Click “Move To”. This is because we have given DPaint III the position we want the brush to move to (.as opposed to where we want the move to begin). 2. Change the Count to 29. Since we are working backwards (Moving To frame 30) diis will leave a blank frame at the beginning. The default setting on Count will always be the actual = of frames you have set so always subtract one frame if you want to start from black. 3. Set “Ease In” to five. This will make sure that there is very little change in position in the last five frames, so that the brush will "ease" into position. The movement will thus appear smoother. We want the brush to appear to come from behind the viewer so set the “Z" figure to 500. Now click “Preview". This will show you tlie moving outline ofyourbrush without actually drawing the frames. This is DPaint Ill’s version of an animator’s “pencil test”. The frames will flash by fairly fast, but it will be obvious that you have not seen 29 frames. This is because we have set the “Z" too high. The animation now starts so far behind die viewer that the first ten or so frames can't even be seen. These are wasted frames. Reset “Z” to 300 and try Preview again. This begins the move just out of our line of sight. Looks good. Now set “Y” to 200 so die brush will appear to come from below the viewer. Try Preview. Again we seem to have several wasted frames. Try “Y" at 105. This time the preview looks alright. Just remember: these numbers are set by trial and error. Anytime that you want to have a brush move in from off-screen watch the preview carefully. If more than a couple of seconds go by between the time you dick Preview and the time you see your bmsh moving then you are wasting frames. This doesn't hurt anything, but why have your Amiga waste time trying to draw frames that no one will ever see? Now we are going to try one more adjustment to make this a really cool move. Set the “X" angle to 90. This will begin your move with die brush at a 90 degree angle to the screen. Remember, by setting “Move To” at the beginning, we have told the program diat all these other coordinates are where we want the brush to move from. Now try Preview. “Kinda like Star Wars, huh?” Except that our brush straightens out at the end of its move so that it will be more legible. This will not be terribly impressive in Preview modeHi Quality Version Available on AMIGALAND.COM as it is a little hard to see, but now diat we are through you can click “Draw". You can also go get a cup of coffee (or the refreshment of your choice) as this will take 5-10 minutes. When you come back from your break, check to see if your animation isstill "cooking". Ifyour pointer isn’t snoozing you’re all done. Now hit F10 to remove the Toolbox and Tide Bar and put the screen in overscan mode. Next, hit five to play your animation and voila! There you are. Amazing what you’ve learned isn't it? How about one more little adjustment5 Let's make your name remain on die screen a little longer at die end. Go to the last frame (“shift-2”). NowgototheSet Frame Count Requester (under Anim), Set the frame count to 100. This will add another 70 frames to your animation. It's important to note that frames are added at the point you are in the animation and that they will be identical to die frame you were on when you added diem. That is why we went to the last frame. We have now added 70 frames at the end of your animation with your name in the same place for all to admire! Just one final touch now. Make sure you're on the last frame (shift-2, remember?) and hit clear. The Clear requester will pop up asking if you want to clear all frames, a range of frames or just the current frame. Click Current Frame. Now your animation begins and ends with a blank screen. Hit five to play it. Classy, huh? You can save this incredible first animation on that formatted disk to show your friends and family later (at lengdi, no doubt) by going to Save under the Anim menu, naming it and clicking OK. Now, I will take a couple of questions from the class. You there, in the back. Why did we use overscan even though the background was black? Good question. We used overscan because our brush was moved in from outside die you set Anti-aliasing to High and repeat the is easy to understand. The second factor is edge of die screen.

That part time... •AC* Animation Ever since the Amiga was introduced, people have been trying to animate with it. In the beginning, we thought the animations being produced were great because we finally had a machine that could do real-time animations. But just by looking at them, one could tell that the Amiga was capable of doing so much more. Part of the reason for this shortcoming was the fact that, in the beginning, there was very little software available to help with the budding animator in his or her quest for the "Most Awesome Spectacle". In late 1985 and early 1986, die only works of animated art being produced came from programmers. These people possessed the knowledge, cunning, foresight, and perhaps stubbornness that allowed them to program the Amiga. Now, of course, the situation is different. There are many programs out there that allow animation of various sorts. These animation programs fall roughly into two categories. The page- flipping type is perhaps die most well-known. An example of Hi Quality Version Available on AMIGALAND.COMthis type of program are the animation capabilities of Sculpt- DeluxePaint III, Anybody who has seen a master of Amiga art like Jim Sachs perform their magic can attest to the fact that DPaint III is a very powerful program. But there are other animation programs out there in the vast expanse of Amiga software. Programs like Videoscape 3D (and its associated software), PageFlipper, Animagic, and a whole host of others. Animate But perhaps the most powerful of die more affordable software pieces is Sculpt 4D. Sculpt-Animate iD (from now on we’ll call it Sculpt), is a very powerful program, it is unique in many of its abilities and has a lot to offer. This article will not try to be a Sculpt tutor. To give a detailed tutorial on the effective use of Sculpt would create a tome larger than most phone books! That is not to say that Sculpt is a very difficult program to use, just that its extreme versatility makes for a very' complex program. Sculpt’s animation abilities fall into two different modes. The Sculpt manual separates them into Global and Frame 4 t > methods. Global animation is a little difficult to grasp at first. It helped me to think of Global animation as a movie set, with myself as die director. To work in die Global animation mode, Hozo To Get Moving In 4D! you have to create an action for each piece of the picture. Each element's action must be completely thought-out in advance. You then instruct each element as to what to do and yell “ACTION!” With a fair degree of forethought, you can create by Lonnie Watson some very stunning effects this way. In fact, some of the “plane- flying-in-a-circle" animations can only be done effectively widi Global animation. Setting up a Global animation is not really that hard. An animation project in Sculpt is known as a points is named, you can treat them, in a way, as one Take.

Due to die space limitations of diis article, I will discuss only diose tecliniques not other­ wise available to the average reader. I would first like to give you some good advice based on my own experience: learn assembly! The only connection I have with computers is my Amiga hobby.

They contain the results of MrgCopO, the system scans through all tire data structures you have setting each of the possible 16 bits in the write-only register known set up and creates "lists" of assembly-like instructions for the as ‘'clxcon,” and of reading each of the possible bits in the one-shot, read-only register known as "clxdat.” Each of these are offsets Copper to execute.

Assign the pointer to your second Bitmap to the Bitmap member of your only Kaslnfo (in the case of double-buffs) or to that of your alternate Raslnfo (in tire case of dual-pfs). c. Set the values of both ''CprList” members of struct View to zero. d. Call MrgCopO again. The system now thinks that it forgot to prepare an area for copper lists, and will generate a second pair oflists plus a second pair of pointers thereto, e. Save tire second set of pointers as you did the first. Voiia! You have two sets of instructions somewhere in memory and two sets of pointers to them, one for each of your two Bitmaps.

However, I am ticles are not intended to be a systematic treatment of all of more interested in the picture itself as an artform. That’s not to them. Instead, I develop the one method that is particularly say Uiat an understanding of die equations is not valuable. It valuable for displaying the Mandelbrot set. Note also that this certainly helps, especially in die never ending search for new article deals only with the method, the series of steps that must equations and for new mediods of displaying them. However, be programed in order to draw a fractal. It is still too early to talk it doesn’t take a mathematician to have a lot of fun drawing about the underlying mathematical theory behind the Mandel­ fractals. All that is needed are a few practical skills and some brot set, although eventually this will be discussed. patience. In this article one such sldll, called scanning die screen, will be developed. SCANNING THE SCREEN In previous articles the development of each fractal was Figure One: observed pixel by pixel, from left to right, and row by row, from Hi Quality Version Available on AMIGALAND.COMOutput produced by this month’s listing bottom to top. That's what is called scanning the screen. It s the (640 x 400 Pixel Mode) systematic plotting (illuminating) of all of tlie pixels on tlie drawing surface. It should come as no surprise drat diere is a standard way of doing this, and once it has been learned, it can be applied over and over again to different programs drat draw different fractals.

ONE HUNDRED TWENTY-EIGHT THOUSAND POINTS OF LIGHT Suppose the screen is scaled as follows:

xmin = -10 xmax = 10 ymin = -10 ymin = 10

Scanning the screen can be started by plotting a point at the bottom left hand comer.

PSET (FNx (xKiir., FNy (ynr.in) 1

Tlie variables xmin and ymin each store die value -10, the Cartesian coordinates of the bottom left hand corner of the drawing surface, as specified by the above scaling. Those values get passed to the coordinate conversion functions FNxO and FNyOi which calculate their corresponding pixel numbers (Amiga coordinates) and then pass them to the PSET command. Refer to Article II in this series if more explanation is needed. Continuing with die systematic scanning of the screen, the very next pixel needs to be plotted along the bottom row. To accomplish this, the pixel’s horizontal coordinate must value of T in steps o f‘dx’, until finally T exceeds xmax. At that be calculated (the vertical coordinate remains the same because point the loop ends and the computer goes on to execute it is in tire same row). whatever program lines follow' die TOR-NEXT construction in die program. THE NEXT PIXEL Here is a complete program which does die above task and noth­ In every example so far, usually on the third line, the ing more. variable dx, which represents the width of one pixel, is calculated using xmin, xmax, and the number of pixels across the screen. Remember that all the pixels are arranged side by DEF FNx(x} = INT(((x-xmin)+dx/2)/dx) side, thus forming a long rowc So, to get to tire next pixel, simply DEF FNy (y) = 195 - INT ( ( (y-ymin) +dy/2) /dy) move to tire right by an amount equal to the width of one pixel, xmir. = - 1 0 dx. Plot the point: xmax - 10 ymi- = -10 ymax = 10 Hi Quality Version Available on AMIGALAND.COMPSET (FNx(xmin+dx),FNy(ymin)) dx = (xmax-xminl/631 dy = (ymax-ymi.nl /1 95 Well, that was simple enough, but what about the next pixel after that? How about: SCREEN 1, 64 0, 200, 4, 2 WINDOW 2, , (0,0)-(531,1861, 0, 1

PSET (FNx(xmin+dx+dx),FNy(ymin)t FOR i=xmin TO xmax STEF dx PSET(FNx(iI,FNy(ymin)) NEXT i

OK then, what about tire next 629 pixels along the entire row'? WINDOW CLOSE 2 FNx(xmin+dx+dx+dx+dx+dx+dx...etc) will not do, it requires SCREEN CLOSE 1 too much typing. AmigaBASIC’s “FOR NEXT” loop construction should be used. Note that in previous examples in the earlier articles an extra dx/

FOR i=xmin to xmax STEP dx 2 was added, as follows: PSET(FNx(i),FNy(ymin)) NEXT i FOR to xmax+dx/2 STEP d>:

In the above loop PSET gets executed 632 times, once for every pixel along the bottom row. The first time through, the The reason for this is to guarantee diat the last pixel along the variable *i' has die value xmin, -10. Each time through die loop row doesn't get accidentally left out. All computers store T gets increased by the value of dx. That’s what the ‘STEP dx’ numbers wridi a limited accuracy. For example, the number 2/ means. In this example the value ofdx is 0.0316957211, buL it 3 gets stored as 0.6666667 which is a little larger than it should is not necessary to know diat. dx is always referred to symboli­ be (die last digit is rounded up to a seven).

The value of dx will be different xmax and xmin its accuracy' could also be questionable. It could whenever you scale die screen to different Cartesian coordi­ also be a little larger tiian it should be. As die loop executes, dx nates. Continuing, each time through the loop the value of T is gets added to T 631 times until it’s supposed to equal xmax. passed first to the coordinate conversion functions, and then to Well, suppose on the 631’th time the value of T actually over­ the PSET command, tiius plotting every pixel along the rowc The shoots xmax by a little bit, say by 0.000001.

As you listen to the weather reports on the radio or evening news this winter, you may hear the an­ nouncer say something like, ‘ the temperature outside is five degrees; but the wind chill temperature is a frigid twenty-four below." Have you ever wondered where that second number comes from? (Especially when you actually step outside and realize how intensely cold iL is when the icy wind hits youHi Quality Version Available on AMIGALAND.COM in the face!) This article will describe a simple pro­ gram which calculates the wind chill temperature based on a choice of inputs, Hill’s Comfort Factor is a measure of tire amount of energy removed from a person's skin because of convection currents caused by winds. Since the number of “calories of energy lost per square centimeter of skin surface per second" is not a very convenient (or ■ useful) measure for most people, something much more familiar will be used. Weather an­ nouncers quote an effective temperature which is based on the W = TO - (TO - T)(a + bv12 + cv) present air temperature and the wind speed. This quantity is called tire “wind chill temperature,” where T is the temperature of still air (as measured by a thermome­ The wind chill temperature (or wind chill factor, as it is ter) and v is the wind speed. The reference temperature TO is frequently — and incorrectly — called) is determined from a non­ approximately that of human skin. (Skin temperature is actually a linear correction to the air temperature. The correction depends on little warmer than the value used for TO because the latter has been wind speed and on the temperature of still air. Some more modified to partially account for humidity of the air and skin sophisticated equations also include the effects of relative humidity, moisture.) The remaining three numbers (a, b, and c) are semi- but since weather announcers rarely provide the humidity during empirical constants, and depend only on the units chosen for the the colder months ofthe year, the program given here is based only variables v, T, and W. on the first two factors.

Primarily, you may have to alter the parameter that unsigned short start,end; is being sorted to some other type, and you may have to change tlie ( unsigned short hold; /‘holdinc value'/ comparison of elements to a function that returns a value less than, equal to, or greater than zero depending upon whether the sort do( should be ascending or descending. Finally, depending upon the while( end > start Si array[end! >= array[start]) /‘greater*/ variable type being sorted, it may be easier to use a function to swap end—; /‘reduce end"/ the elements rather than doing it in line twice. Now that you know recursion is permissable, you may if (end != start){ /‘if not on start*/ discover just where it can help you in your programs. Just hold *= array [start] ; /‘hold value*/ arraylstart] = array[end!; /‘swap values*/ remember to keep in mind that there is a danger of doing recursion array[end] ° hold; /‘swap values'/ unwisely. But with a little experimenting, you wall know exactly when and where to use your new knowledge. •AC* AC Disks Source code, executable, and IFF pictures (when available) included for all articles printed m Amazing Computing.
