Dženan Zukić writes: Hi, I have read some older threads why aren't shapes appearing in obj files. I understand the problem, but for inexperienced OSG users like myself it is quite hard to improve OBJ exporter to capture the triangles that are used to draw ShapeDrawables. Has anyone written some code that solves or circumvents this problem? Hi Dženan, OsgWorks (http://code.google.com/p/osgworks/) has osg::Geometry-based utility functions to render rudimentary shapes such as planes, boxes, spheres, and arrows., so you can substitute your shapes for several of those an they will get written in the file. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Front to back blending in osgVolume
Hi, I'm currently looking into the osgVolume nodekit and the osgVolume example as I'm trying to implement a simple volume raycasting shader in osg, which I have previously written in Rendermokey. The shader calculates the direction for the ray by rendering the front and back faces of a unit cube. The difference between the faces is stored in a texture and serves for the direction look up. I'm using front to back blending as I need to integrate early ray termination due to performance reasons. As far as I understand it by looking at the source, the osgVolume example uses back to front blending and I'm wondering, if the functionality for front to back blending is already available in osgVolume. What would be the best way for generating the direction texture in this case? Can this be done directly in osg or do I have to use for example osgPPU in order to setup my rendertargets? Any hints are greatly appreciated. Thank you!
