[osg-users] render quad texture to arbitrary quadrilateral

Hello, im trying to render a texture to an quadrilateral. The quadrilateral is the calculated by the intersection view frustum with aplane. So the image basically a perspective projection of the original image. Unfortunately the texture coordinates are not interpolated correctly such that

Thanks. Do i understand it corrently that the semantics of nodemask is completely user specific. And in osg in stereo context 0x1 means left cam and 0x2 means right cam? How can i define which parts of the mask are rendered with my camera? I tried to set the nodemask of my Camera, but it did

[osg-users] Projecting a texture onto the scene geometry

Is there a way in osg to project a given texture, a 3d location and focal length onto the 3d geometry, for example a surface mesh, of a scene using osg? -- You received this message because you are subscribed to the Google Groups "OpenSceneGraph Users" group. To unsubscribe from this group

[osg-users] Anaglyph and NodeMask issue

I use node mask to show or hide parts of the scene graph. When enabling stereo mode in osg, it seems to completely ignore the node mask. Is this expected behaviour? osg::DisplaySettings::instance()->setStereoMode(osg::DisplaySettings:: ANAGLYPHIC );

Is there a way to do this directly with osg or does it need a custom implementation? If no, is anybody able to share code for how to render a depthmap with intrinsic camera parameters as a 3d pointcloud using shaders? Am Mittwoch, 12. Juni 2019 21:18:38 UTC+2 schrieb Trajce Nikolov NICK: > > Hi

[osg-users] Re: Textured ply file is black when loaded.

While i agree that it makes no sense for ply to support any application specific formats, I still support the idea of allowing for importing a small subset of possibilities. If the plugin is called osgdb_ply.dll, how should one know that it only supports the semantic of equalizergraphics. Is

[osg-users] Re: Loading textured meshes (obj+mtl) leads to crash in osg 3.4.1

Thank you for the workaround. So as far as i understand you only add the texture coordinate and normal, if there exists one with a index greater than 0 and less then the number of normals or texture coordinates. So that means that openscenegraph now will be able to display the textured mesh,
