WebMar 12, 2024 · When an array size is specified in a declaration, it must be an: integral constant expression (see section 4.3.3 "Constant Expressions") greater than zero. An array whose size is specified in its declaration or determined by: its initializer is _explicitly-sized_. An array whose size is not specified in a declaration is _unsized_. 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.
