Lighting and shading is a critical technique for the-art rendering and image enhancement techniques for interpreting many kinds of volume data. VolumeViz uses all types of 2D and 3D image data. These advanced the GPU to compute gradient vectors and an application techniques execute on the GPU, taking full advantage of its can specify a fast or high quality algorithm as shown in the multi-core parallel processing architecture and tremendous below figure. performance advantage over the CPU. The “shaders” that implement these techniques are complex programs in themselves, but VolumeViz applications can simply select their desired rendering options and VolumeViz does the rest. Both performance (interactivity) and image quality are important, but it may not be possible to maximize both at the same time. Even a high end graphics board may slow down when doing very high quality rendering in a large window. So VolumeViz provides the options you need to maximize interactivity or image quality or take a balanced approach. Low vs. high quality gradients You can trade off quality for interactivity while investigating a data set and then switch to maximum quality for final images. VolumeViz can also automatically An application can also specify linear interpolation of increase interactivity by temporarily decreasing the image data values, as done on traditional graphics hardware, or a quality while the user is interacting with the scene, then high quality cubic interpolation computed on the GPU, as return to full quality when the interaction stops. shown in the below figure. Generally increasing image quality requires increasing the sampling rate, which may reduce interactivity. VolumeViz provides a number of techniques to improve image quality without decreasing performance. For example “pre-integrated” volume rendering allows a lower sampling rate to achieve the same quality. And “jittering” is an anti-aliasing technique that removes rendering artifacts (sometimes called “ringing”) caused by low sample rates, as shown in the below figure.

Linear vs. cubic interpolation

An application can also adjust various parameters that control the algorithms on the GPU. For example, some data sets have noisy regions where many small gradients are computed, but are not meaningful. The gradient threshold parameter can be used to suppress these and light only the more significant data, as shown in the below figure.

Without vs. with jittering

VolumeViz provides extensive support for lighting effects in volume rendering, but traditional techniques can be expensive and reduce interactivity. So VolumeViz provides state of the art screen-space, post-rendering algorithms including deferred lighting and ambient occlusion that provide realistic appearance without the cost of computing a gradient for every voxel. In many cases, faux shading produces results that are very similar to surface shading but without the Gradient threshold 0.0 vs. 0.1 performance penalty for computing gradients and lighting.

Custom shaders are often used to combine multiple volumes in various ways using the GPU. VolumeViz makes this easy by performing all the setup. The application just provides the source code for the shader, sets any parameters that the shader will need and specifies which volumes should be combined. It is also possible to specify a separate data range and color map for each volume. Useful applications of this technique include rendering segmented volumes using a second “label” volume to specify the voxel color, masking volume regions using a second “mask” volume to control voxel visibility, and so on.
