Features

• Ray marching of distance fields done on the Gpu inspired by IQ demo “Slisesix” and  Shadertoy. The video shows two scenes rendered with a pixel shader: the simple scene showing basic distance fields and the more elaborated one, showing procedural distance fields and shading.

Features

• Flock simulation using tasks in order to keep busy all the cpu cores. It uses the Vista Pool Thread API to make a really simple wrap for send multiple tasks to the pool. The video shows how most of cpu cores (hardware threads) are not working under a heavy load of work with only one task in the pool. If the work is spread across multiple tasks, the video shows how all the cpu cores are busy.
