Hi Ralf, It should be straight forward to recompile Delta3D against OSG 2.6, while it's isn't binary compatible with OSG 2.4 the API is very close and shouldn't introduce any porting issues. Robert. On Tue, Aug 12, 2008 at 9:19 PM, Ralf Stokholm <[EMAIL PROTECTED]> wrote: > Hi Robert > > Thanks

Re: [osg-users] Mouse motion models across multiple viewports

Hi Bob, osgViewer does try to cope with multiple camera/window configurations by projecting the local window coordinates into view coordinates - normally this is enough to ensure consistent mouse values on mulitpipe systems. For a dome it could get a bit more tricky, and it wouldn't certainly be

Re: [osg-users] FPS Motion Model

The problem is that through osg there is no way to get the raw mouse values. In normal mouse mode you can get the x, y and the delta values but once you move the mouse to the extent of the window we no longer get deltas even though we move the mouse. The quick and dirty solution is to recente

Hi Nicholoas, I haven't any experience with using Maya let alone MViewportRenderer, but add this in shouldn't be difficult - have a look at the GraphicsWindowEmbedded feature in osgViewer as a means of quickly integrating OSG rendering, see the osgsdl and osgglut examples to see how this is used.

Hi Sam, For just off screen rendering, and no other windowing, you can use pbuffer, see the osgscreencapture example in 2.6 for guidance. If you have a graphics context already then using a FBO will be just fine - for this see osgprerender. Robert. On Thu, Aug 7, 2008 at 10:41 AM, Sam <[EMAIL
