[osg-users] OcclusionQueryNode woes

Hi all, I'm having some issues regarding OcclusionQueryNode. I draw an object as a set of faces and a set of edges, and I can't seem to get OQN to deal with both as a single entity, resulting in an artifact where for a fixed camera position the object becomes intermittent (disappears, then re

Re: [osg-users] OcclusionQueryNode woes

Hi Paul, So I can reproduce the problem by running "osgocclusionquery .osg"? (all that example does is place an OQN above the .osg file that is loaded.) If so, please post your .osg file so I can take a look at the problem. I had forgotten osgocclusionquery could read external files. It seems

Re: [osg-users] OcclusionQueryNode woes

Hi, I think that's still a bit beyond my osg/gl skills, and more so given my time frame; hence the convenience of using library code. (If this feature is already built in, I couldn't find it, please point!) I'll have a look at it if this doesn't pan out, anyway. Thanks, E. Jean-Sébastien Gu

Re: [osg-users] Problem with default lighting

Ach, I've had a couple hectic days and forgot to answer until now. Thank you (and Robert both), that was it and I overlooked it. I've managed to replicate this behaviour converting from sketchup to osg file formats through obj and collada, so I guess the problem might be on either end. I'll try

[osg-users] Object position on screen coordinates

Hi all, first message here. I want to translate the position of a number of objects on screen coordinates, so that I can create a hud-like bubble over each of them at z=0 giving feedback on the objects' name, status, etc. From what I see I could use intersectors, as a sort of inverse picking, b

[osg-users] TrackballManipulator with pitch, yaw and no roll

Hi, I'd like to have a TrackballManipulator with a rotation behaviour resembling that of TerrainManipulator with rotation mode ELEVATION_AZIM (as opposed to ELEVATION_AZIM_ROLL). It'd be very useful for drawing and manipulating buildings and other constructs of that sort. I've been trying to r

Re: [osg-users] osg-conv collada

Hi, I'm trying to get the collada plugin working and running into this problem too. I've tried Johan Nouvel's suggestion (a few messages later) to no avail. I'm using osg 2.3.7 and the last pre-2.0 stable release for collada, 1.4.1 DOM 3.0. Did anyone find a way around it? Also, what are the p
