Hello, I've been investigating that source code but can't seem to find where the 2D tiled/LOD image rendering is handled. Can you give me some insight please? Thank you 2016-07-06 9:43 GMT+01:00 Sebastian Messerschmidt < sebastian.messerschm...@gmx.de>: > Am 06.07.2016 um 10:31 schrieb Christian

[osg-users] Sidescan sonar image

2016-07-28 Thread Dario Minieri
Hi, I would to implement a rendering pass which emulates a sidescan sonar. In practice I would to rendering an image of current frustum view "colored" in base to distance of objects. Can you suggest to me a good way to achieve that? I think I have to work about depth map but maybe you can sugg

Re: [osg-users] osgsimplegl3 example, is it possible to run on some combination of OSG and OSX?

Hi Robert, Sorry to bother you gain, but I have been watching and I cannot say for sure if there was any progress on this for OSX or not. Are things ready for OSX and being able to at least run the osgsimplegl3 example yet? Watching all the commits and messages I got a bit confused as to exactly

Just write a fragment shader that looks up a 1D texture (containing a color gradient) based on the fragment's Z coordinate. You could whip up a demo of this in something like ShaderToy very quickly; On Thu, Jul 28, 2016 at 7:49 AM, Dario Minieri wrote: > Hi, > > I would to implement a rendering

Re: [osg-users] [build] OSX X11 Build System Failures

2016-07-28 Thread Ravi Mathur
Hi all, I realized that the OpenGL link dependencies for OSG are not quite correct for OSX/X11. Specifically, if OSG_WINDOWING_SYSTEM is X11 then osgViewer is built with X11/OpenGL, but osg (base) is still built with Cocoa/OpenGL. This mismatch of OpenGL implementations can cause very unexpecte
