WebGL1 uses GLSL … 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: http://kylehalladay.com/blog/tutorial/vulkan/2024/01/28/Textue-Arrays-Vulkan.html hunter osrs calc
