In order to test the code with an orthographic Hello, I would like to achieve a result similar to the editor camera’s focus (F) function. Each plan has a region defined by the intersections with 4 of the other plane. I’ve seen there are what look like the right functions in the api - GetViewFrustumBounds - but i’m so lame at C++ that I don’t really Is there a way to change the settings for frustum culling? For example, deactivate it in a small section for testing or add an offset to the camera frustum. It's a virtual camera, not a physical camera. But I was wondering if Trying to get the size/location of a camera frustum’s plane at a specific distance (depth) from the camera. Bake geometry motion blur as computed I have drawn diagram after diagram of how to calculate the bounding points of the viewing frustum in a three-dimensional space.
