Re: [osg-users] gluDisk - how with OSG?

The osgWorks project has a makeCircle function that will create a solid disk. To create a disk with a hole in it, use the makeOpenCylinder function with a 0.0 length and different radii for the cylinder ends. osgWorks is here: osgworks.googlecode.com -Paul On 12/10/2012 2:20 AM,

Re: [osg-users] Rendering sets of objects in layers/passes

Use a different Camera for each set, and on each Camera call: cam-setClearMask( GL_DEPTH_BUFFER_BIT ) so that they clear only the depth buffer and not the color buffer. -Paul On 12/8/2012 2:34 PM, Preet wrote: Hiya, I have multiple sets of depth sorted geometry that I'd like rendered in

Re: [osg-users] GLES2/Trigonometry Question

(Sorry if this shows up twice; I originally posted it Tuesday but it has not echoed back to the list. Test emails seem to work, so trying again...) Hi Jeremy -- Since you know the FOV in y (it's 45.0 degrees), you can compute the distance to fit a bounding sphere with the following code:

Re: [osg-users] OSC plugin on Windows?

Hi all -- There was an issue in this update that caused VS to misinterpret the libraries. The attached osc CMakeLists.txt fixes the issue and results in a clean build. -Paul On 11/20/2012 3:38 AM, Robert Osfield wrote: Hi Paul, Christian, Stephan et. al, On 20 November 2012 07:36,

[osg-users] OSC plugin on Windows?

Hi Stephan -- Is the OSC plugin tested on Windows? I'm getting several undefined symbols during link using VS2010, building 32bit on Win7 (see below). I don't see any CMake controls to disallow this plugin on Windows, so I'm guessing these are build errors that should be fixed. -Paul

Re: [osg-users] Are shaders not saved during osgDB::writeNodeFile?

I did this: osgconv glsl_confetti.osgt out.osg then looked at out.osg in an editor and it definitely contains shaders. -Paul On 11/16/2012 9:36 PM, michael kapelko wrote: Hi. I've attached custom shader for a node in a ShadowedScene. I then called osgDB::writeNodeFile upon it and found

Re: [osg-users] Oddities when loading a FLT file

I had another thought on this, Chris. Set a breakpoint in the Multiswitch constructor and verify that the missing Multiswitch is being created under both circumstances. Assuming that test passes, set a breakpoint in the Multiswitch destructor, it should get hit when the missing Multiswitch is

Are you sure you're getting the same FLT file in both cases? Echo the full path returned by osgDB::findDataFile(). -Paul On 11/8/2012 7:55 PM, Chris Hanson wrote: I've encountered a strange behavior when loading a client-supplied FLT file and I haven't been able to drill down and find

I'm definitely open to having such code contributed to osgWorks, where they would be Geometry-based rather than ShapeDrawable-based. -Paul On 10/28/2012 10:28 PM, Andrey Zubarev wrote: Hi, all! In OSG we have some simple 3D primitives such as Sphere, Cylinder, etc., even Capsule! But
