[osg-users] Issues with main website when looking to post a bug...

2013-03-25 Thread Robert Spearman
Wondering why Tracker is not used for bug reports. Is that a longer term plan? The main site has a number of problems when one tries to figure out how to report a bug: Login link does not explain that one should not try to log in, nor that there is no place to register, and that the forum

[osg-users] osgVolume should never use a predefined border color

2013-03-25 Thread Robert Spearman
In openscenegraph-3.0.0/OpenSceneGraph/src/osgVolume/RayTracedTechnique.cpp the 3D texture is being clamped to a border color of (0,0,0,0). It seems to me this should be CLAMP_TO_EDGE rather than CLAMP_TO_BORDER, since using a border color not in the actual texture is completely arbitrary. I'm

Re: [osg-users] ReadImage not routing to plugin?

2016-09-24 Thread Robert Spearman
OK, I see the design flaw I was missing. You have to load a plugin library in order to see what extensions it handles, and plugins are only loaded when needed. But "needed" can only be known if you have loaded the plugin already. That's why there are so many hard coded extensions in the

Re: [osg-users] ReadImage not routing to plugin?

I did get the plugin to be used by preloading the plugin library - had been using the wrong parameter. But my question is, why do I have to manually load a plugin? Why isn't this automatic if the extension to plugin mapping is already in the registry? Thanks, Rob

[osg-users] osgParticle behavior with discontinuous and reversed time

2017-01-14 Thread Robert Spearman
I have a simulator where time can go forward or backward and I am integrating an osgParticle system which draws line particles. My particle lifetimes are under 1 second. I am looking for suggestions on the following problems: When I jump ahead in simulation time (by a week, for example)

[osg-users] Attach TextureBuffer to camera?

2018-12-28 Thread Robert Spearman
When I try to attach a TextureBuffer texture to a camera via the attach method I get the error: "Error: FrameBufferAttachment::FrameBufferAttachment(Camera::Attachment&) passed an unrecognised Texture type." FrameBufferAttachment(Camera::Attachment& attachment) has no case for a

[osg-users] Is ShaderStorageBufferBinding global?

2019-09-29 Thread Robert Spearman
I have two nodes, A and B, each with their own SSBOs being bound to slot 0.  A loads first, and then B.  They are on different scene graph branches. It looks like node B replaces the SSBO binding set up by A.  The compute shader on A then modifies the SSBO used by B, causing neither node to
