Projective Texturing


Recommended Posts

Hello everyone... sorry for another noob question but I am learning and loving babylon! :P

I am curious if babylon can project a texture onto multiple objects... similiar to how this is: http://playground.babylonjs.com/#1215MA

but I want to be able to project from a specific point in the scene.. not from the active camera but maybe another camera in the scene?

Maybe the mirrorTexture or the reflectionProbe thingies might help you, too?


mirrorTexture: http://doc.babylonjs.com/tutorials/01._Advanced_Texturing (under the heading "mirror" pretty much at the top :P )

reflectionProbe: http://doc.babylonjs.com/tutorials/How_to_use_Reflection_probes


And wouldn't it somehow be possible to use a dynamicTexture to display certain camera view? Somehow I think I saw something like this already, but I can't remember where... maybe I am confusing things here, so don't pin me down on that ;)

haha yeah, I wish it was more straight forward to do it...

I kind of found a three.js example and tried to mimic it but there are a few things i need to fix:


1) stop the image from changing position when you change the size of the browser at load time

2) there is a weird white ring behind the camera


is there a way I can share my scene in a babylon Playground with the custom shader?

No no, of course not. Shaders are awesome as far as I know. I just never took the time to learn how to use them (yet). And I am kinda scared of them... looks like complicated jibber jabber to me. But you can do alot of great stuff with them, so if you already figured it all out, good for you! I'll catch up some time later... maybe ;)

Would any shader gurus be able to help me out here?

I am trying to get rid of the gigantic ring is this example:




my cameras projection  matrix is being plugged into my shader and whenever i do that I get this ring...sad face

Also the ring gets bigger the farther you dolly out with the render camera :S


I feel like its a simple fix and I am just missing something


thanks! :)
