Opengl uniform block
Web3 de out. de 2024 · Adds a new block layout (scalar) for uniform, push constant, and storage: buffer blocks. This new layout aligns values only to the scalar components of the block: and its composite members. Additionally, this extension now allows uniform blocks to be decorated: with the std430 layout.

WebYou can get all uniforms and which blocks they are in by calling gl.getActiveUniform and gl.getActiveUniforms. gl.getProgramParameter(program, gl.ACTIVE_UNIFORMS) returns the number of uniforms. You then create an array of indices to pass to gl.getActiveUniforms and pass it gl.UNIFORM_BLOCK_INDEX. -1 = not in a block.
