Re: [osg-users] Question about rendering

Hello Robert, Thank you. I have some problem when I try to run iPhone example of the OSG source. After referring to this post(http://forum.openscenegraph.org/viewtopic.php?t=14385 ), I figured out both the VERTEX xxx failed problem and texture not support problem by adding Code:

Re: [osg-users] Thread safety in OSG

Thank you for your response. The scene is only used for calculating LOS. The function providing this can be called by multiple threads though. At the moment I lock the access to the scene: Code: osgSim::LineOfSight los; los.addLOS(start, end); // It is unknown whether OSG changes m_scene

Re: [osg-users] Improving this scene frame rate

Hi, I found where is the error, but I don't know how to solve it... I'm sending identity matrix to the computeMatrixPaletteUniform(geom.getMatrixFromSkeletonToGeometry(), geom.getInvMatrixFromSkeletonToGeometry()) all the time into void operator()(osgAnimation::RigGeometry geom). So in the

Re: [osg-users] Half Side-by-side

Hi, as suggested, I've solved setting OFF the OSG_SPLIT_STEREO_AUTO_ADJUST_ASPECT_RATIO option and setting SIDE_BY_SIDE stereo HORIZONTAL or TOP_AND_BOTTOM. :-) Thank you! Cheers, Francesco Francesco Argese -- Read this topic online here:

[osg-users] moving a vertex of a Geometry

Hi All, I have a surface where a user can pick points. As suggested I used a Geode with Geometry built with osg::PrimitiveSet::POINTS and verteices. Then I used PointSprite to show an image on each point (but I think this is not really important). Now I need to drag points with the mouse.

Re: [osg-users] moving a vertex of a Geometry

Hi Gianni, years ago whan I was working on a 3D editor I faced similar challenge. I solved it with selection buffer, where I had two representation of the model - one for fast rendering, when you obviously don't pick or manipulate, so your model with osg::PrimitiveSet::POINTS will represent this,

[osg-users] Implementing glEnablei + glDisablei

Hi All, I'm currently working on multiple render target functionality, yesterday I checking in ColorMaski, BlendFunci and BlendEquationi, and today I've moved on to implementing glEnablei/glDisablei functionality. I'm torn of what naming convention to use and the granularity of the design - so

Re: [osg-users] Transparent Window Application [SOLVED]

Hi, Great to see that you got around the transparent mouse clicks as well. I just needed it yesterday and again your method works great. Unfortunatly I have another problem though... I would like to place this application on top of another full-screen windows (game). I didn't think of it

Re: [osg-users] Transparent Window Application [SOLVED]

Hi Roy, if you game runs full screen and cannot do anything else even with 'full screen emulation' ( such that you render game full screen but in windowed mode ) the answer might be - an old trick to use hooks to write overlays for games ( search on the web - the trick is used in number of

Re: [osg-users] Implementing glEnablei + glDisablei

HI All, Since then a decade and half has passed and looking at modern docs for OpenGL the glEnable/glDisable and glEnablei/glDisablei now discuss OpenGL capability rather than modes. I guess the new naming sits better modern shader centric functionality. Given this perhaps if one is to
