WebAs an OpenGL extension, seamless cubemap filtering can be manipulated on a per-texture or per-sampler object basis. Note that if you use the global version, it will still globally force seamless behavior on all cubemaps. This is governed by a simple boolean sampler parameter, GL_TEXTURE_CUBE_MAP_SEAMLESS. WebGLSL Tutorial – Texture Coordinates. Texture coordinates are commonly used to define how an image maps to a surface. However texture coordinates are not restricted to perform this mapping. Texture coordinates per se can be used to color a model. Here we will see a couple examples of how texture coordinates can be used on their own.
