Hi,
I put one plane ahead of my camera, according to my understanding of 3d pipeline, all the stuff behind the plane should be cut. Then the draw calls, triangles, FPS should down a lot. But what I saw is, whether put a plane ahead of my camera of not, doesn’t affect almost anything. That is against of my understanding of zbuffer.
Can anyone kindly explain this to me?
Thanks in advance.
From another post someone answered me this is not zbuffer but occlution culling. He is right I think.
So now my question is, does unity 2.x support this feature now? I see on iphone, but how about on desktop?
I’m pretty sure culling is in 3.0. Not in 2.6…
You have to setup occlusion culling. Unity 3 will have it for iPhone, Android, destop, webplayer, and I assume the consoles, but I haven’t seen that stated anywhere. In 2.6, only iPhone has occlusion culling.
Currently in 2.6, Unity uses frustrum culling and back face culling. If something is outside the camera’s frame, it isn’t drawn, but Unity currently will draw objects that you can’t see if their in the camera’s viewing window.
Just to correct / expand that: In Unity 3 Pro and the Pro addons you will have it, the free and non-pro addons don’t have it
I have the iPhone basic beta, and I can still generate occlusion culling. I haven’t tested it in a build, but it works fine in the editor.
