Mega Particles
Instead of rendering textured billboards, this technique called “Mega Particles” render spheres to an off-screen texture. This texture is then blurred and randomly displaced using a fractal cube. The...
View ArticleFluid Simulation and Rendering
For effects like smoke or water, a fluid simulation and rendering approach is needed. There are currently two popular methods for this: Simulate the fluid on the CPU and send the result as particles to...
