WebAn Array Texture is a Texture where each mipmap level contains an array of images of the same size. Array textures may have Mipmaps, but each mipmap in the texture has the same number of levels.. The domain of the images in the array depend on the array texture's specific type. Array textures come in 1D and 2D types, with cubemap arrays … WebGLSL, however, provides for array data-types. The array types must be "sized" (have a specific, final size) in order to be usable, so no "pointer" types are available, but we don't need them for this type of operation. We can define a "lights" uniform which is declared as a sized array of 12 vec4 elements:

WebMay 6, 2015 · Each element in the array is one clip plane. In order to use this variable, the user must manually redeclare it with an explicit size. With GLSL 4.10 or ARB_separate_shader_objects, the whole gl_PerVertex block needs to be redeclared. Otherwise just the gl_ClipDistance built-in needs to be redeclared.
