camera view as a texture? Is there any way i can use the camera view as a texture in realtime? i know you could do this in the blender game editor before using python, but now i don't know if there is a way i can use the camera view as a texture (or colour output, basically) without rendering or baking it

kind of like a security guard monititor or a portal effect, i think you could do this kind of effect in the compositor using masks but that wouldn't really help
You can still use python for Scripting. I have not tried it yet but from searching web there are commands to put in script to render the camera's view, save that to file, then set object texture to file, write another script to constantly update the objects texture.

Render camera view to file.
Set texture to file. 
Keep rendering and updating texture in background script.
