Viewed 1k times. 0. 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. DX11 occlusion culling tutorial - Braynzar Soft. Occlusion culling increases rendering performance simply by not rendering geometry that is outside the view frustum or hidden by objects closer to the camera. Two common types of occlusion culling are occlusion query and early-z rejection .

This document contains a short summary of these methods, but it’s mainly focused on improving hierarchical occlusion culling algorithm performance by making use of DirectCompute technology. This technology is a part of Microsoft DirectX 11 API, which helps the developer to use graphics processor for general-purpose computation. April 11, 2005 . Culling. One of DirectX has back face culling built into it, and using it is as simple as switching it on. Occlusion culling basically means to cull the scene that is In this video, I show another update to my DirectX 12 rendering engine. In this case, I added SSAO and improved camera movement.

In Direct3D 11.4 for Windows 10, there are nine feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards, levels 10_0, 10_1 refer to respective legacy versions of Direct3D 10, 11_0 and 11_1 reflects the feature introduced with Direct3D 11 and Direct3D 11.1 APIs and 2010-06-07 · This talk brings you up to speed with the API, offers tips on how to get your renderer up and running, presents key feature overviews, and shows how to deploy your application. Attending this talk is highly recommended if you are attending other DirectX 11 presentations.

The depth buffer should not be full sized, in my code I’m using 512×256. There is a Frostbite paper that mentions using a 256×114-ish sized buffer for a similar solution to do occlusion culling. In DirectX 10, whether a face is front or back depends on you, there is filed called FrontCounterClockwise in D3D10_RASTERIZER_DESC, and it's default value is FALSE, and the deault cull mode is D3D10_CULL_BACK, same as DirectX 9. In DirectX 11, the D3D11_RASTERIZER_DESC has same members as that in DirectX 10, but unfortunately, the document Has anyone used this for the purpose of occlusion culling and had it work for them?

This excerpt from Programming a Multiplayer FPS in DirectX explores a variety of \$\begingroup\$ yes, I know you can set culling to back face culling or front face culling (or none) but that doesn't solve the problem. because of the way ambient occlusion works, you have to flip some of the the faces. that means some will need backface culling and some will need frontface culling.
