Re: [osg-users] Attaching children to the prerender camera

Hi Mary-Ann, I have recently worked on similar issue and the way how I debug the depth RTT was by rendering the Depth image on a quad (the shader for displaying the Depth image is here: http://markmail.org/message/ ccscbkzyxsgmb5vl#query:+page:1+mid:c542rbpj3jdw3v5d+state:results ) or simply

[osg-users] Attaching children to the prerender camera

Hi, I am pretty new in OSG, so sorry if I am asking a bit noob question. But I am stuck on this problem, and have no idea how I could solve it. So I would like to prerender my scene into a framebuffer to have a depth map. I tested everything, my shader seems to work if I am using it in my main

Re: [osg-users] different materials for a geometry and highlight

OK, I found a way to move a triangle from a primitive set to another. Debugging the code primitive sets are updated correctly but the color remains the same. I call sourcePrimitiveSet->dirty(); destinationPrimitiveSet->dirty(); geometry->dirtyBound(); What's wrong with it? Isn't enough?

Re: [osg-users] different materials for a geometry and highlight

Hi Gianni, I browsed the LineSegmentIntersector code and it seems, the intersector is using a triangleFunctor to traverse your primitive sets as triangles anyways. So the Ifnromation So basically you cannot find out which primitive set was affected without reverse-engineering which primitive

Hi Gianni, Code: osg::Geometry* buildGeometry() { osg::Geometry* geometry = new osg::Geometry; geometry->setVertexArray(buildVertices()); geometry->setColorArray(buildColors(), osg::Array::BIND_PER_PRIMITIVE_SET); std::vector elements =

Re: [osg-users] different materials for a geometry and highlight

Hi All, I've attached an example. Hope this helps to have a reply from somebody (Robert?). Part of that example is from the OSG 3 Cookbook. Suppose I have geometry build of triangles. I would like to understand which is the better way to change the color of a selected triangle. And if there is

Re: [osg-users] Feedback/guidance sought on move of osgQt out into it's own project/repository

Hi Mathieu, One of the items that could complicate things is the qfont plugin as this would normally be placed in the lib/osgPlugins-version directory. This coupling to a specific OSG version is not helpful for the osgQt build or maintainers. I think the solution is to simply place the
