Re: [osg-users] RTT Camera does not render anything

Hi, I changed my camera. Now I don't use the method where I create the rtt camera, like shown in first post. Now I just created the camera in the method where I setup the scene and it works... I really do not get why Is there a specific order I should follow with the camera calls

Re: [osg-users] RTT Camera does not render anything

Hi, ok that was a big mistake from my side. I forgot to set the width and height of the Texture, but I used getTextureWidth() and getTextureHeight to specify the Viewport. Well if the Viewport is (0, 0, 0, 0) there will be nothing to see. But the thing with the orientation I am still trying

Re: [osg-users] RTT Camera does not render anything

Hi, my bad for not explaining it very well ;) I want the following: With the RTT Camera I want to render a specific geometry. The texture I get from that, will be used in the main scene later. The RTT Camera must not point in the same direction as the main camera. If this would be the case

Re: [osg-users] RTT Camera does not render anything

Re: [osg-users] RTT Camera does not render anything

You lost me here, You want a relative RTT camera (pointing to where the main camera points to) but you set up da absolute camera (having its independent Viewport, matrix etc.) You most likely want to have a ABSOLUTE ref frame for screenspace passes and final output only- Cheers Sebastian

Re: [osg-users] RTT Camera does not render anything

Maybe you forgot to add the camera to the main scene graph? An addChild() into the scene graph root should do the trick. 2015-04-14 15:16 GMT+02:00 Andreas Schreiber a...@online.de: Hi I'm trying to generate a texture with a rtt-camera, so I can use this texture later in my main scene.

[osg-users] RTT Camera does not render anything

Hi I'm trying to generate a texture with a rtt-camera, so I can use this texture later in my main scene. To verify if the texture is correct I'm trying to put the texture on a quad in my main scene. I use the following method for the rtt-camera, the red clearColor I used to test what the
