Re: [osg-users] Is OSG tied to OpenGL?

Cory, Answering the last portion of your question ... OSG is UI toolkit agnostic. But, if your asking a general question of which toolkit is better supported on its own right ... then ... Just my 2 cents (take it for what it's worth), but for strictly C++ development I highly recommend Qt. I

[osg-users] RTT CameraNode and cull mask

Hello, I'm having trouble getting culling to work for a CameraNode that's used with RTT. Is there anything inherently wrong with trying to do this? I'm assuming cull/node masks still apply with RTT. Without having to send too much code, I'm using RTT with post-filtering to emulate a sensor

[osg-users] osgCal or osgCal2?

Hello, Are there compatibility issues with osgCal or osgCal2 when using OSG 2.X? Also, since osgCal2 is LGPL, is it “preferred” by OSG developers? If memory serves me correctly, osgCal is GPL. Thanks, Ben No virus found in this outgoing message. Checked by AVG Free Edition. Version:

Rob, I’ve written some classes that implement RTT and post-filtering using OSG and GLSL shaders. Let me know if interested. I thought about putting in Wiki when I get time. You can take the output of one RTT stage and apply it as an input to the next stage … ganging them together …

[osg-users] Rapidly updating texture data

Hello, Is there a way to repeatedly/efficiently update an OSG texture's data ... for example imagery data that is being updating in system memory (e.g. from a sensor capture device). I've tried updating an OSG texture using texture2D-setImage(data) ... but it is very slow. Again, the image data

Thanks J.P. You say that I can call myim-dirty() or myim-setImage(), but wouldn't calling myim-setImage() cause a slow update? That's what I seem to be experiencing. I need to update based on the sensor around 30Hz. The imagery data (from sensor) is in system memory ... just trying to get a
