Shadows are shadow rays toward a point light. The chrome ball is almost pure metal. The red and mint balls mix diffuse with a little reflection. The whole scene is one GLSL fragment shader.","apis":["WebGL 1","GLSL ES 1.0","requestAnimationFrame","matchMedia"],"tags":["shader","raytrace"],"hasGlsl":true,"interaction":null,"url":"https://3d-retro.com/experiments/raytracer","example_url":"https://3d-retro.com/examples/raytracer.html","api_url":"https://3d-retro.com/api/v1/experiments/raytracer","html":"\n\n\n \n \n \n \n Reflective spheres · 3d retro graphics\n \n\n\n
