What you want to do can be easily done using a Uniform array. See the
Uniform header. For the shader side of things, see the orange book, or
attend my upcoming OpenGL 3 course: www.techsoupcorp.com.

So I would like to be able to use an array of positions inside the vertex shader that I would index with gl_InstanceID and use that to offset the current instance. The array of positions would then be updated from the render thread every frame in a callback.Could someone tell me how to set this up in the shader and how to access the array in the callback function?
