How to set oblique view frustum?

Hi, I am developping a reflect material on Cesium, I need to set the camera view frustum’s near plane to be arbitrary plane, for example:

figure from

Is it possible to do that on Cesium?


That sounds pretty cool! You can change the near and far planes for the camera here:

If you want to rotate the plane, I think you may need to modify the source code. I’d take a look at the camera class here:

Note that there is an orthographic frustum you can switch to if that’s your goal, see:

Thanks your reply.

Yeap, it needs to modify the source code, so that I can use custom projection matrix
