nCine::RHI::GU::GuShaderUniformBlocks class

#include <nCine/Graphics/RHI/GU/GuShaderUniforms.h>

Manages the uniform-block caches of a program (aliased as RHI::ShaderUniformBlocks).

Owns a GuUniformBlockCache per active block, distributes a shared host data buffer across them, copies the block contents into a suballocated range of the streaming uniform buffer on CommitUniformBlocks(), and on Bind() forwards each range to the device so the effect running the following draw can sample it.

Public types

using UniformHashMapType = std::vector<GuUniformBlockCache>

using UniformRangeAllocator = RHI::BufferRange(*)(std::uint32_t bytes)

Function that suballocates a range of the given size from the streaming uniform buffer.

Public static functions

static void SetUniformRangeAllocator(UniformRangeAllocator allocator)

Sets the allocator used by CommitUniformBlocks() (registered by the pipeline at startup).
