From c6fe9547aa59d10ea1b367d8b88982e10a0f617f Mon Sep 17 00:00:00 2001 From: ssdfasd <2156608475@qq.com> Date: Wed, 25 Mar 2026 00:26:16 +0800 Subject: [PATCH] RHI: Add DescriptorSet abstraction for D3D12 and OpenGL backends - Add RHIDescriptorSet base class with Update/UpdateSampler/GetNativeHandle - Add RHIDescriptorPool with AllocateSet/FreeSet methods - Add SetGraphicsDescriptorSets/SetComputeDescriptorSets to RHICommandList - Implement D3D12DescriptorSet using descriptor heap allocation - Implement OpenGLDescriptorSet using TextureUnitAllocator - Add CreateDescriptorPool/CreateDescriptorSet factory methods to RHIDevice - Fix unit test SetVertexBuffer -> SetVertexBuffers API - Add SetVertexBuffer convenience method for D3D12 backward compatibility
