WebGL Water Simulation

A pool of water rendered with reflection, refraction, caustics, and ambient occlusion. The pool is simulated with a heightfield and contains a sphere that can interact with the water's surface. This demo will only work on WebGL implementations with graphics cards that support floating point textures, screen-space partial derivatives, and vertex texture fetches.

Features:

• Raytraced reflections and refractions
• Analytic ambient occlusion
• Heightfield water simulation
• Soft shadows
• Caustics

Interactions:

• Draw on the water to make ripples
• Drag the background to rotate the camera
• Press SPACEBAR to pause and unpause
• Drag the sphere to move it around
• Press the L key to set the light direction
• Press the G key to toggle gravity
