WebPath tracing is a realistic lighting algorithm that simulates light bouncing around a scene. This path tracer uses WebGL for realtime performance and supports diffuse, mirrored, and glossy surfaces. The path tracer is continually rendering, so the scene will start off grainy and become smoother over time. Here's how to interact with it: Web24. nov 2013 · If the sphere is transformed away from the origin and you care about rotation and scaling of the sphere, then the equation of the sphere becomes more complex with …
