This technique uses software rasterization to render occluders to the downscaled depth buffer and test occludees against it. Everything is done on the CPU. The most recent paper on this is from Intel. Intel suggest an efficient SIMD-optimized way to rasterize and test boxes agains a depth buffer. Summary.

OpenGL, Vulkan and Metal have all recently released features that DirectX 11 Tutorials. Tutorial 1: Setting up DirectX 11 with Visual Studio Tutorial 3: Initializing DirectX 11.

(Also works with simplified lighting in DX11) --- So I was playing around a lot trying to get the game to not run completely abysmally and ended  With occlusion culling the aim is to identify and reject occluded regions of 3D scenes in order to improve rendering performance. Within this category of  View frustum culling for lights (CPU). All work was done using DirectX 11 API. ATI Radeon HD5730 GPU was used for development. All images were rendered  If the range of the lights is known, then we can perform frustum culling on the light volumes before rendering the scene  14 Nov 2018 Uses software rasterizer to render occluders into a zbuffer, and then creates a hiz -buffer, for occlusion culling.

Josh Bycer in SUPERJUMP. Se hela listan på docs.microsoft.com The term occlusion culling refers to a method that tries to reduce the rendering load on the graphics system by eliminating (that is, culling) objects from the rendering pipeline if they are hidden (that is, occluded) by other objects.

Second, every object's bounding mesh is rendered. The meshes are re-rendered and then their occlusion queries are retrieved. Finally, the surface's scene is ended and deactivated.

Right now I'm using Predication to cull my BV tree after I first cull it with a few different view frustums, to get different ranges of objects to pass on to other parts of the engine. In theory, the algorithm has a lot of advantages compared to occlusion query based algorithms: - Less stalling (just once for fetching the results from the GPU (dx9)) - One draw call for culling many, many objects Cons: [s]- Very coarse culling for objects that are big in screenspace. Can make it pretty useless in a lot of cases. If there is a better method for occlusion culling, please let me know. This appears to work well when used correctly, but I'm not sure how to correctly use it. and I find Microsoft's reference guide to be useless for learning.
