hi everybody.

Do you know "portal"?
It's a unique new game.
If you use NVIDIA, you can play trial version for free.
The link is http://www.steampowered.com/nvidia/

The system of portal is very interesting!
I try to implement the warp system with xith3d but...
I can't come up with any good idea.

If you make a game or warp system like portal, how do you implement that?

Well, even if I have an NVIDIA card, I don't have time to boot to windows and try it out. And I definitely won't install Steam.

Could you please post a screenshot of the warp system in effect?

So the "warp" effect, you're talking about is simply the see-through-a-wall effect, isn't it? I would suggest to do this as follows:

Render the scene to a texture, that you want to see through the wall. Then project this texture onto the wall.

Another solution would be to use the stencil buffer.

Please have look at the RenderToTextureTest, ProjectiveTextureTest and StencilTest for reference.

i refer them.
additionally, I want to know how to transfer
between current scene and another through a wall.

thanks for your reply.

Well, if the user hits a portal, you would simply need to change the player's position to the transportation target's location.
