[osg-users] osgText and getting fonts on OS X becoming difficult

Hi, it is becoming more and more difficult to obtain the filenames of fonts in OS X. Actually, it seems to be that all system functions are depreciated that obtain from a font object (like NSFont) the font's filename (directly or indirectly). What do you do to get from a native font object in

[osg-users] StateSetManipulator doesn't work

Hi, I have a strange problem. Runing the following code will cause StateSetManipulator doesn't work. That is I can't enble/ disable texture by clicking key T (And the Lighting, CyclePolygonMode). I've tried. If keep only one geom-addPrimitiveSet of the first two POLYGONs, remove the

Re: [osg-users] Any libraries of public domain shapes for Open Scene Graph?

I am not the original poster, but I'd love to see a library of implicitly (mathematically) defined shapes that use GLSL raytracing/raymarching for rendering. So you can get perfect spheres without any geometry load. Spheres, Cones, etc... that kind of stuff that is hard to tacke with meshes. If

[osg-users] osgShadow and multitexturing

Hi y'all I'm trying to implement shadow in my scene. My scene makes use of up to 4 texture levels in its models. I read in some comments that the lipsm and other shader based shadow techniques are not really made for multi texturing. Ist here anybody out there that made a custom shader that

Re: [osg-users] Incorrect volume image

Hi Robert, I appreciated your details explanation. My program was using coin3D for volume rendering previously and it was working fine on Intel graphics machine, so I expected osg can work the same. I absolutely agree with your point of view. I have set the minimum requirement for

[osg-users] Rubber band selection for pixel masking

Hi all, I'm trying to implement a rubber band selection tool (and also a polygonal selection tool), and I'm wondering which is best approach since there are a number of options in OSG and it's a bit confusing... Note that I don't really need the PolytopeIntersector, because I need to create a bit

Re: [osg-users] osgShadow and multitexturing

Hi Daniel, All the osgShadow techniques can work with multi-texturing and it's certainly how I'd expect most users to use it. However, the built in shaders they provide can't handle all the types of effects you might want to use so you'll need to replace these with your own custom shaders.

[osg-users] Can't resize framebuffer texture attachments

I'm trying to resize the textures attached to my framebuffer during run-time, however the viewport size that the scene is rendered into stays the same. If the framebuffer starts off at 64x64 pixels and I then resize to 512x512, the output only contains rendered pixels in the lower left 64x64

[osg-users] Texture render ratio?

Hi, Lets say I have a texture 800 * 480. I have a quad which is 10 * 10. If I render the texture to the quad, the texture will be squashed on the x axis. How do I compensate for this, correct the aspect ratio? ... Thank you! Cheers, Paul -- Read this topic online here:
