Re: [osg-users] Multiple Cameras and lagging proj matrix

I did come up with a reasonably confined solution for this, and I've added it to the osgWorks project, see: https://code.google.com/p/osgworks/source/browse/trunk/src/osgwTools/MultiCameraProjectionMatrix.cpp and the associated header in include/osgwTools/MultiCameraProjectionMatrix.h. MultiCame

[osg-users] osg coordinate system

Hello. Osg uses a coordinate system in which the +y axis goes into the screen and +z axis goes up. Does this default matrix affects the model matrix of each object on the scene or the view matrix of all the cameras ? I wish i could remove this behavior. thnx. _

Re: [osg-users] Loading .ive via curl on Android

If you are trying to load the original earth_bayarea withouth modifications then, probably, you will never see a thing because it uses a DXT texture compression which is not supported in GLES. Have a nice day. 2012/12/6 Tisham Dhar > Hi All, > > I have the GLES1 sample working with textures on

Re: [osg-users] What can I do to improve rendering performance for a bunch of billboarded nodes?

Hi you can use point sprites for this purpose instead of billboards\autotransforms, it should be much faster as you need only one drawable per single geometry type(triangles, squares, ngons, etc). you can shape them either in fragment shader based on point coords, or apply small texture. Cheers. 21

Re: [osg-users] osgAnimation

Hi iirc osgAnimation animation is not get started by default when viewer starts, you should start it in code. You can use osganimationviewer binary from osg examples or write your own utility for your purpose. Also osg and ive file formats lacks some support of osgAnimation, try using osgb or o

Re: [osg-users] Render multiple osgText nodes with the same drawcall

Hi my suggestion is not about text, but anyway, if your models contain tristripped geometry, they issue single draw call per primitiveSet (mean for each triangle strip) and they usually not so lenthy at all, about 7-10 vertices on average. With display lists this dont matter, but on gles it can hav
