Re: [osg-users] rendering millions of spheres

Hi Robert, you are right, and probably that is the best approach. How would you approach the coalescing of drops? I am aware of papers of "properly" doing it as well. However, I took the fastest approach :-) ... Tried that in Modo based on some modeling tutorial and now trying to mimic it into rea

Re: [osg-users] rendering millions of spheres

Thanks Robert, and Alistair for the detailed info. I have done this in the past as you mentioned with geometry shaders by passing the centers and radiuses as vertex array and attribs and expanding them into spheres in a geometry shader. Can not use it now though. So your another hint was the sample

Re: [osg-users] rendering millions of spheres

In order to render a large amount of identical primitives, you probably want to use either instancing or geometry shaders. If your target hardware supports OpenGl 3.x features, then the latter is better. You can use arrays of per-vertex data to specify the differences between your spheres (radiu

Re: [osg-users] [osgOcean] Regulate the Ocean Reflection intensity.

Hi, Looking the patch, I've seen that this is the same mod that I've tried but doesn't looks good to me...I'm using the trunk version, so the patch is different because some stuffs are moved in Technique file, but the mod is the same and I'm not really able to tone down (mean: add a lower refle

Re: [osg-users] How to getting the number of vertices

Hi Kim, Have a look at the osgUtil::StatsVisitor, you'll find it in the include/osgUtil/Statistics header. Robert. On 2 December 2013 06:49, Kim JongBum wrote: > Hi, > > i would like to know the number of vertices in the scene. > > i know how to see the value of vertices as i press 's'button.
