[osg-users] Setting Colors

Good morning @all I have a question about setting colors of a geometry. We have 3d- objects which is described by a triangle area. This triangle area has a color, which is set with a ColorArray and a ColorBinding (BIND_OVERALL) Now I want to give a inner and outer color for the triangle

Re: [osg-users] trackball moves slower when zooming

Hi Roni Could it be, that the zooming depends on the eye-distance. eye-distance * zoom-factor If you come closer the zoom-step will decrease... I think this is the concept which is implemented in OpenSceneGraph. Daniel Am 06.05.2008 um 12:51 schrieb Roni Rosenzweig: Hello In my application

Re: [osg-users] A question about zooming with orthographic projection

Hi Ke Li You can implement a zooming functionality with the camera function setProjectionMatrixAsOrtho(...) We also use a orthographic projection in 3d. And we implement our zoom with this nice function. I hope this will help... Have a nice evening! Daniel Moos Am 18.03.2008 um 19:55

Re: [osg-users] polytopeIntersector
