[osg-users] bluring model edges

Hi, Is it possible to blur the edges of a model in OSG with whatever is behind? Currently the edges of the models in my scene are too sharp and would look better if there was a translucent overlap at the edges. Is this possible to achieve in OSG, or is this kind of functionality more relevant t

Re: [osg-users] generate height map using fractal

Wow. That article is like 13 years old. I think I wrote it with VC4 and OpenGL 1.1. As a debugging technique, try to separate the heightfield population algorithm from the rendering issue. For example, try populating the heightfield with an array of linearly increasing values and see if it render

Re: [osg-users] Camera vs Projection

Robert, I didn't mean to annoy, I tried to see if there is a conventional solution within the tools I already used. I didn't want to change the Projection to camera. For me the problem was to keep the Z order when using different projection matrices. What finally solved the solution was to proj

Re: [osg-users] Camera vs Projection

An osg::Camera that has it's RenderOrder to NESTED will just set the project and view matrices, it want clear any buffers and will nest all enclosed sugraph within the current RenderStage. This makes it pretty close to the use of Projection node and Matr

Hi You can set an environment variable to set the initial size set OSG_WINDOW="100 100 500 500" >From the command line you can use : --window 100 100 500 500 e.g. osgviewer cow.osg --window 100 100 500 500 You can also use a config file to set the windows up osgviewer cow.osg -c OpenSceneGaph

Hi Michael, Normally this is pretty straight forward, you just need to point you library path at the libraries, either via LD_LIBRARY_PATH or your /etc/ld.so.conf. Obviously you are doing something wrong along the route, but there is no way for me to know what this is though as I don't have you ma

[osg-users] Camera vs Projection

Amit, You should place AttitudeAndPosition transform above your geode, there is also a transformation that deals with 6DOF under osgSimulation. You should add a callback that updates the position ond direction of the transform, and you have it. Guy. Hello All, Does anyone have a prog

Re: [osg-users] Animating vertices in a Geode

I think you just need to use update callback for your geometry, in this callback you set the vertex array with the new locations and then call dirty() to ensure the update of the display list. Guy. Hi, In the application I am working on, I am trying to create a smooth (transition) animation on
