Try turning off lighting for your stateset. I know English may not be your primary language, but your language and writing style make it very difficult to read and understand your message. Thank you!

Hi, em using Flight gear 1.9.0 with osg 2.8.0 The terrain and sky is generated in the window using 2 cameras far and near i tried 2 set window color to black using Osg - setColor(osg::Vec4(0.0f, 0.0f, 0.0f, 1.0f)) and even tried with glut - glclearColor(0.0f, 0.0f, 0.0f, 1.0f) but only sky color is set 2 black and terrain and object and still present how can i remove terrain or set it to black .. @cris i tried to set the Nodemask to 0 but code doesn't come out of idle function ... ie window is not loaded :( ...

Re: [osg-users] FOV
Hi, Thanks chris .. em able to zoom using getProjectionMatrixAsPerspective and setProjectionMatrixAsPerspective fuctions Actually em trying this view for LDP instead of Aircraft and i want to make my view as entire black screen (instead of Runway) during initialization until i select some modes Wat parameters in which function should i set to get black screen Any suggestion plz share :| ...

Well, if you do getProjectionMatrixAsPerspective: http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00073.html#0d5e678648b19df3b64dec0d06fef974 and then alter the fovy and resubmit it with setProjectionMatrixAsPerspective: http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00073.html#fe4fab17f1cc5b4664c17ed79717aabb This will keep all the same view, except alter the change the zoom (field of view). -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
