Real-Time Volumetric Caustics with Projected Light Beams
Gábor Liktor, Carsten Dachsbacher · 2010
We present a method for the visualization of volumetric caustics in single-scattering participating media. The caustics beams are generated from a projected grid in light’s image space, making the solution independent from the geometric complexity of generators. The caustic volumes are extruded in the geometry shader and accumulated into the final volumetric effect.
