Re: [osg-users] How to add shadows to deferred shading?

Hi folks, Sorry for hijacking this thread, but after a relatively long time I'll have to work on deferred shadow mapping again. I did sample implementation using mentioned osgRecipes' EffectCompositor some time ago: https://bitbucket.org/kornerr/osg-deferred-shading I checked out the

Re: [osg-users] Setting update callback for osgSim::LightPointNode has no effect

HI Nick, The way the OSG implement node callbacks are as traversal callbacks that are nested within the traverse of the node itself, so it's in effect a traverse children callback. In the case of osgSim::LightPointNode it's implemented as a leaf node so doesn't bother calling

Re: [osg-users] How to add shadows to deferred shading?

Hi. I failed to implement shadows myself and failed to understand osgShadow, so ended up simply using it in a separate pass, as you outlined. Can't help here, sorry. 2015-10-27 16:02 GMT+07:00 Sebastian Messerschmidt < sebastian.messerschm...@gmx.de>: > Hi folks, > > Sorry for hijacking this

[osg-users] Setting update callback for osgSim::LightPointNode has no effect

Hi community, I installed an update callback to a osgSim::LightPointNode .. However it is never called. Any hints, clue? Thanks as always! Nick -- trajce nikolov nick ___ osg-users mailing list osg-users@lists.openscenegraph.org

[osg-users] how to set width and Stipple of a osgText::BoundingBox?

Hi, I want to modify text.cpp so can set osgText::BoundingBox's width and line Stipple. Here is how osg draw BOUNDINGBOX in text.cpp: if (_drawMode & BOUNDINGBOX) { if (_textBB.valid()) { state.applyTextureMode(0,GL_TEXTURE_2D,osg::StateAttribute::OFF);

Re: [osg-users] OSGNode VBO Control

Hi, I can spend sometime exploring render order. The scene has a few dynamic elements and I believe if the uploads for those elements happens after the VBO draw-calls then I am likely suffering a longer pipeline stall then I really can afford. ... Thank you! Cheers, Ignitus

Re: [osg-users] OSGNode VBO Control

Hi Ignitus, I can't help feel that you are diving into low level stuff way you've established that it's required. The OSG can manage update's to VBO's for you, it doesn't current support updating parts of osg::Array, potentially you can implement this yourself with a custom draw callback or

[osg-users] OSGNode VBO Control

Hi, I'm starting to work my way through the source for Geometry and Drawable, but more experienced minds might be able to point me in the right directions sooner. I'm working on a AR HUD and because a later point in the project might require the loading of complex models to represent avatars

Re: [osg-users] how to set width and Stipple of a osgText::BoundingBox?

Hi Lv, I haven't tried modifying the drawing style of bounding box of an osgText::Text before, but it should be possible by decorating the Text subgraph with an osg::StateSet with the osg::LineStipple and osg::LineWidth StateAttributes attached to the StateSet to control the stipple and line

Re: [osg-users] how to set width and Stipple of a osgText::BoundingBox?

Hi Lv, osgText::Text implementation is very pretty old now, with a design driven by the needs of very old hardware. If I were to rewrite osgText I would not implement it the has been. I would not recommend adding OpenGL coding into osgText::Text as this breaks OSG's ability to do lazy state

Re: [osg-users] how to set width and Stipple of a osgText::BoundingBox?

Thx!Robert! The situation is,we have modified the text.cpp to create some other styles rather than boundingbox. Like a BoundingLine,one end to one of the corner of a BoundingBox,the other end linked to a osg::Node. So if a text have a BoundingLine and a BoundingBox,I just want

Re: [osg-users] Third-Person Camera Manipulator

Hi, This turned out to be an issue with the FBX exporter in Blender. The issue only occurred when I was exporting my model as the "FBX 7.4 binary" option. When I switched to the "FBX 6.1 ascii" option, then the model exported with the correct scale and coordinate frame. Evidently, the osg fbx
