Funny raytracer. Minecraft flight keys for movement, o/k/l/; for camera.
It will not work on mobile because webgpu (and also raytracing on your phone would be a bit decadent
will be noisy, especially during day scenes. Stand still for a moment to allow convergence :heart:

Lol exec() users rise up 
anyways to declare a material, here's the API (wow I'm an awful person) (also remember to registry.register):

  Material.constructor({
    diffuseCol = [0.5,0.5,0.5], specularCol = [0.5,0.5,0.5], emissionCol = [0,0,0], 
    diffuseStr = 1,             specularHardness = 400,      roughness = 0,         
    reflectCol = [0.9,0.9,0.9], absorbCol = [0.0,0.0,0.0],   transmitCol = [1,1,1], 
    reflectStr = 0,             ior = 1,                     transness = 0,         
  }={}) 

There are also default materials: basic, mirror, glow, glass, glowglass and diffuse (under materials.)
  
The included meshes are dragon, pillars and cube. The API for affinetransform is

  function affineTransform({
    xrot=0,   yrot=0,   zrot=0,   rot=[0,0,0],
    xscale=1, yscale=1, zscale=1, scale=[1,1,1],
    xmove=0,  ymove=0,  zmove=0,  offset=[0,0,0] 
  })
