WebHere is an example of a structure. struct light { float intensity; vec3 position; } ; The new data type is called light. To use it you can use a constructor that is avaliable once the stuct is defined. light lightVar = light ( 3.0, vec3 (1.0, 2.0, 3.0) ); Stuctures can have arrays, however the size must be initialized within the structure.

WebAug 8, 2024 · GLSL does not have pointers. But it does have shader storage buffer objects, which allow you to define arbitrarily large regions of memory that the shader can read from.A "pointer" in this model is just an index into an array of data structures. You have to do the indexing explicitly in GLSL code. WebMar 27, 2024 · Vulkan requires that the SPIR-V it consumes provides explicit byte offsets and array/matrix strides; it doesn't allow you to use std140 layout. It is the GLSL-to-SPIR-V compiler that creates these offsets&strides by applying the OpenGL std140 rules. It's GLSL/OpenGL that decides what std140 means. – Nicol Bolas. chris cordwell
