The patches are evaluated in JavaScript at load, with analytic normals, in Newell's own proportions (the 4/3 vertical squash some renderers apply is not used). Lighting is per-pixel Phong with two point lights that sit in the scene as little orbs. Move the pointer: the key light follows, the fill stays opposite. Ceramic, lamp, and fill colours are on the tweak row.","apis":["WebGL 1","GLSL ES 1.0","Pointer Events","requestAnimationFrame","matchMedia"],"tags":["webgl","3d"],"hasGlsl":true,"interaction":"Move the pointer to drag the two lights around the teapot.","url":"https://3d-retro.com/experiments/teapot","example_url":"https://3d-retro.com/examples/teapot.html","api_url":"https://3d-retro.com/api/v1/experiments/teapot","html":"\n\n\n \n \n \n \n Utah teapot · 3d retro graphics\n \n\n\n
