    Putting a path tracer in a 3D playground: crash a car, gun a plane, fly a helicopter

    Part one's room stood still. This part takes the same path tracer outdoors and puts in a character you steer, five cars, a helicopter and an aeroplane, with the light computed anew every frame. When anything moves, every accumulated sample is void; four things keep it playable all the same.

    How a picture clears from snow: a WebGPU path tracer from scratch

    The colour of one pixel is the average of many rays bouncing at random. Watch a picture clear from noise, shoot one ray and see how it becomes a colour, flip one switch that cuts the noise five times, swap in metal and glass, and see how a BVH keeps a million triangles running.
