Instructions
- The Debug View panel allows you to see the textures generated during the "shadow pass", ie. the rendering from the light's perspective.
- The Samples slider is to control the number of samples used in the indirect illumination computation.
- The Sample Range slider controls the maximum radius that a sample can be taken from in a 512x512 texture.
- The Reflection Factor slider controls the amount of light reflected by the surfaces in the scene, which is used as a factor in the flux texture. You can see how it impacts the flux computation in the corresponding debug view.
- You can toggle the interpolation scheme described in the paper. It's way less expensive but also less accurate especially in sharp corners.
- When the interpolation scheme is on, you can also toggle a mode to visualize the zones where interpolation fails in red.
- You can toggle the animation to move the lights to see the different colors of the walls reflecting on the main object.
