First of all thank you for your reply. I have a point cloud structured in octree, where each node (PagedLOD) of the scene contains a part of the cloud which show points colored by their intensities using a gray scale (0: black --> 1: white). What I need is to let the user to show points colored by their elevation (z value) when he push a button in a toolbar.
Nodes are loaded using osgDB::readNodeFile(path, myOptions), where myOptions is an object of a class I have derived from osgDB::Options and in which I have included some parameters that allow to set the color mode (elevation color or gray scale). So, when I need to switch to the evelation view mode, I update some parameters in node options using setDatabaseOptions method of my PagedLOD node and this works fine. The problem is that the colors on the scene are updated only when I move from the current position, while I need to automatically refresh colors from the same camera position. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=68237#68237 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
