Re: [Opensg-users] Support for OpenGL Instancing?

[Christoph F. <c.f...@gm...>]

Hi,

I would strongly second that :)
But there are several ways of transferring the per-instance data (transformation matrices),
see for an overview: http://sol.gfxile.net/instancing.html

For our project, we have implemented a derived MaterialDrawable for a single glDrawElementsInstanced call
using the "Matrices in a texture" approach (via GLSL variable "gl_InstanceID").
You need single-indexed geometry data with one primitive (e.g. triangle_strip). 

Cheers,
Christoph
