[osg-users] [ShaderComposition] Redondant call to useProgram

Hi Robert, Using the new shader composition (ex osgshadercompostion), I was surprised to detect a lot of redondant call to gluseprogram... I debugged a few and don't understand well State::push/popDefine and its policy to invalidate defineMap (defineMap.changed = true; seams to be called at

[osg-users] [CubeMap with mipmaps] About loading IBL

Hi all I'm trying to load an IBL cubemap with lod but when I'm trying to set mipmapdata (and so override hardware mipmap generation) the cubemap appears black (even the first level that i actually validated with HWMipMapGeneration /: ?! ).. Any leads? Thank you! Cheers, Julien

Re: [osg-users] [osganimation branch] Review, test, critics

Hi I'm a bit concerned about the nathan.osg compatibility with RigTransHW.. I attached in my last a modified version of nathan (without shared ss) that should work (and so would replace the current one in osgdata). I would be glad if Raymond (or other) could validate this model (ideally under

Re: [osg-users] [osganimation branch] Review, test, critics

Okay Concerning problems encountered with nathan and HWtrans I think i remember the difference of behavior of the RigTransformHW: 1/In master nathan HW have the "luck" to work because SourceGeometries share stateset. In this case a stateset is process mulitple times by RigTransHW::init()

Re: [osg-users] [osganimation branch] Review, test, critics

Hi Robert I just did a commit of my experimental useless bone removal method. So long so far I didn't have any issue with my Blender test models (which represent a "outnumbered sample" of 2 models...one with ik the other with morphtarget) However, I didn't have any feedback from the community or

pushed your logic on the gpu side (cull,material,texture,physics,ai). I do my testing on GT440 and even with it I achieve really amazing stuff Cheers robertosfield wrote: > Hi Julian et. al, > > On 28 July 2017 at 17:53, Julien Valentin < ()> wrote: > > > Hi, >
