Render point cloud in a different coordinate system
Reply with quote

I have a big point cloud, which has points in meter coordinates. Now I want to transform the coordinates of this cloud for rendering only, without changing my point cloud data. How can I do this?

Decorate your subgraph with a Transform node such as
osg::MatrixTransform or osg::PositionAttitudeTransform.

Go search through the OpenSceneGraph/examples/* set for example.

Also please consider getting the OSG book, this will help you
understand more about the OSG

Robert.
