For my current project, involving augmneted reality i want an actor to appear coming out of a (virtual) slot in my (real) table.
The Problem is: i need to hide/cut/clip away part of the actor (where it is covered by that slot). I made a quick sketch to explain better whatr i want to achieve:
On the left and right side are two different ways/objects illustrated, that should both do the trick, but i dont know how to make these clipping-objects invisible and hide/cut/clip away the part off the actor (panda) that is behind it.
Any ideas how to do that? Or is there a simpler way?
i already experimented with th clippingplanes you described, the problem is the clipping-effect only occures when the actor intersects with the plane. I need it to clip when the model is behind the plane(s). Is this possible?
I made a bether illustration to describe the effect i am after:
The grey Object is the 3D-Object i want to hide/cut/clip, the desk is a real video picture which will be put into the background.
not terribly sure but wouldnt that be a good example for stencil buffers? i wanted to get the same effect onces. i ended up projecting the webcam-texture onto the object but i figured there must be cleaner weays to do this.
I agree, stencil buffers sound like the right thing to use here. A stencil buffer can be used to obscure everything except for a certain region in screen space.
thank you guys, i read a bit into stencilbuffers and it seems that it can do what i want to archieve. Is there any advantage in using the depthbuffer instead the stencilbuffer?
