[osg-users] osgUtil::Tessellator getting back new structure.

Hi Every one, I am using osgUtil::Tessellator to tessellate a few polygons. However I don't want to use the viewer to draw them. I just want the vertices of the new structure returned. I am using the following options

Hi Carlos, I havn't got to osg::TriMesh (yet( so you'll have to dig the source on that. I wrote terrain nodetree, so could be anything from flt to ive to 3ds, i.e the algo the I described need only vertices and drawables. I dont' know what your software will eventually do, and you may need the

Hi Sherman, I don't think your code is in error, nor that AutoTransform or small feature culling is in error, rather it's unfortunately chicken and the egg which came first? type dependency. The ways to break the culling of custom node in the first frame would be: To switch off small feature

Re: [osg-users] How to hide a RTT camera's clear color

Hi Coz, If your RTT is set up correctly, then It might be simply that the texturing you are using in your shaders of your main scene graph (that uses the RTT textures) aren't doing what you want. From your texture it does kinda sound like your aren't using texturing though... There is so much

[osg-users] Getting current eyepoint

I have an update callback that needs the current frames (i.e. the one that's about to be rendered with the cull/draw traversals to follow) eyepoint. When I used the camera's view matrix, I seemed to be getting last frame's eyepoint - it hadn't been updated yet? When I changed my update

Re: [osg-users] Getting current eyepoint

Hi Bob, The default setting of the view matrix is done at the end of Viewer::updateTraversal(), after the update visitor runs through the scene graph calling update callbacks. This is done so that any camera manipulators that track nodes can set themselves correctly. In your case you are

[osg-users] matrix concept - newbie

Hello forum, Quite new to this rendering system. I would like to know which file does contain the mapping of the OSG matrix(2D) to the OpenGL matrix(1D) in the Source? Regards Sajjad ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] matrix concept - newbie

Hi Sajjad, The OSG only has 4x4 Matrix classes, OpenGL itself also just has 4x4 matrices, save for some specific uniforms that have 4x3 matrices. There are no 2D or 1D matrices in either the OSG or OpenGL. Could you please explain what you are trying to achieve, then perhaps others will be able

Re: [osg-users] matrix concept - newbie

Sounds like he is referring to how OpenGL stores the matrices, as a 1d array of 16 elements, while OSG stores them as a 2d array of 4x4. biv On 8/25/08 10:43 AM, Robert Osfield [EMAIL PROTECTED] wrote: Hi Sajjad, The OSG only has 4x4 Matrix classes, OpenGL itself also just has 4x4
