WebThe cost of traversing an osg::Camera in cull should be very small, and one can avoid using a separate RenderStage by using a NESTED_TRAVERSAL. Using a different custom Node to do similar RTT ...

WebNov 27, 2014 · 1 Answer. You only need to know 3 things to do this: the view direction, the position of the camera and the position of the node (all in the same coordinate system). Then the test is easy: dot (view, nodePos-cameraPos)<0 where dot (v1, v2) is the dot product of 2 vectors in other words v1.x*v2.x + v1.y*v2.y + v1.z*v2.z. WebAnd it's easy to reset: lod->setRangeMode ( osg::LOD::DISTANCE_FROM_EYE_POINT ); This mechanism should be useful if we want to load specified level of. a LOD node at some time. For instance, high-res capturing requires. multiple projection matrices for sub-rendering cameras, but leaves the. modelview matrix alone. the doc bv

WebJan 8, 2015 · So Im using Open Scene graph to create an application and I have a callback class that extends from OSG's callback class. Its just a callback that is called each … WebThe cull callback is called from OSG's culling traversal. If OSG determines that an object's bounding sphere intersects the viewing frustum, it calls the cull callback -- if there is one -- to traverse that object and perform finer grain culling. If there is no cull callback, OSG does the traversal itself. WebA 3D Mapping Engine & SDK for OpenSceneGraph.
