you have to replace getEventQueue()->mouseButtonPress(event->click_x, event->click_x, 1); by getEventQueue()->mouseButtonPress( event->click_x, event->click_y, 1); ___ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mail

Re: [osg-users] LightPointNode and shaders

Hi Brad, Can shaders be added to a osg::LightPointNode? I'm trying to add both a vertex and fragment shader (pointsprite) but I just don't see any effect. I don't have problems with shader based pointsprites on nvidia hardware. don't forget this line: stateset->setMode(GL_VERTEX_PROGRAM_P

Re: [osg-users] can someone reccomend a good starting point ?

Hi Bryan , I would like to be able to view this model using OSG, since examples I've seen show fast rendering among other things. I have also written an animation of a growin neuron using matlab and VRML's extrusion capabilites, which I believe osg has, and I would like to recreate this in osg.

Hi bm, None of that is very useful but it is fun to play with, so I thought I'd share it with the group. i saw the video and i like to see artistic uses of OSG. Even if it is mostly just for fun so it shows how powerful OSG is to make demos, pre-process images etc. I remember i did some

Hi all, i did some testings with a modified osgPrerender example: what i tried was to use the image target of a CameraNode as input for a VertexTexture, controlling the vertex.z of a model in the scenegraph ( using a vertexshader ). It works good, but it seems for me that the GPU internal pre
