The documentation is vague on this subject. js, materials are coupled vertex fragment shaders and geometries are arrays of vector positions. This is a limitation of WebGL, not three. The image files used in this lesson can be downloaded from the file named material-textures. When mipmapping is enabled (default), the GPU will use different size versions of a texture to render a surface depending on how far away it is from the camera. js, tutorial Some weeks ago I was asked if it is possible to have transparent video texture in THREE.
