[osg-users] Generating terrain mesh using 3D points

Hi, Has anyone tried generating a terrain mesh using 3D points? Any advice of how to get started? I have some terrain data consisting of 3D points and need to develop functions to query the terrain height during runtime. Thank you! Cheers, Linda -- Read this topic online her

[osg-users] Window Position of Widget

Ok, I tried attaching it to the root node and the color now works, previously it was attached to a ShadowedScene node which was itself attached to the root. So obviously something in that ShadowedScene node is causing the problem, I still don't know what it is as I don't do set anything in the s

[osg-users] osgText setColor problem

Hi, I've got a simple function which creates a text object and attaches it to a Geode: osg::ref_ptr drawLabels() { osg::ref_ptr geode = new osg::Geode; osg::ref_ptr font = osgText::readFontFile("fonts/forte.ttf"); osg::ref_ptr text1 = new osgText::Text; text1->s

Hi Sanat, There are no functions in the OSG for computing intersections of polygons models with other polygonal models. Robert. On Thu, Mar 10, 2011 at 12:04 AM, Sanat Talmaki wrote: > Hi, > > I had a quick question if I can check for intersection/overlap between > Polygons of two different 3D

Re: [osg-users] Getting Uniform Value in drawImplementation

Hi Carl, It sounds like you are most of the way there, osg::State maintains the list of current state that has been applied so you just need to get the current uniform set from the osg::State object. The stumbling block is that is presently any accessors for the internal data structers and these
