Radiosity Shooting vs Gathering is a free applet that shows users the graphic difference between two radiosity algorithms: shooting and gathering.

The algorithms are animated for each iteration of the algorithms and the resulting visualization of a discretized scene and of its form factor matrix can be viewed as the animation progresses.

Select an algorithm to animate. Select a shading method (flat or Gouraud). If the shooting algorithm was selected, then choose to visualize either the total radiosity of a patch or the unshot radiosity of a patch.

Choose a mesh density (values above 3 can be slow on some machines). Press the ">" button to begin the animation. The animation can be paused by pressing the "||" button. You can also go through the animation frame by frame by using the ">>" button.
