WebNVAPI_D3D12_PSO_REQUEST_FAST_GEOMETRY_SHADER_DESC_V1 Struct Reference WebAside from on Intel hardware, geometry shaders are software implementations only and perform really badly, you should avoid them. You're better off using a compute shader to generate the geometry, and then use the results in your rendering. Going the compute route you can still even optimize the mesh as well as an added bonus.

WebFeb 28, 2024 · Apple put devs in a bit of a rock and a hard place by refusing to support more modern OpenGL versions that support compute shaders. OSX is limited to OpenGL 4.1, which supports geometry shaders but not compute. Metal, as you've found, does not support geometry shaders, but does support compute shaders. WebFeb 2, 2024 · Occlusion culling with geometry shaders. Arguably the first fully GPU driven occlusion culling method, pioneered by Daniel Rákos. The main idea is to render occludees as points (with bounding box data as attributes) and: Vertex shader checks the bounding box agains the frustum. If visible, sends the vertex to the geometry shader. tarif parking lillenium
