Drive GPU instances with data

We’re making a visualization of a MRI (Magnetic Resonance Imaging), basically we have for every moment in time for every point in space a numeric value. This value represents the brain activity in that point in that time. From this information, we would like to make a 3D network that evolves in time. The user is going to be able to move around the brain. We´re mapping the user’s position in a room with a Kinect and moving a 3d camera with it.
We’re currently using geometry instancing, but it only allows us to specify the position/rotation/scale we don’t have access to each instance to modify it according to the data.
We tried using the replicator and it works, but only with a few dozen of data points. We have 14280 points :stuck_out_tongue:.
We haven’t worked with Glsl before.
Would anyone point us in the right direction please? The project file is attached.

Hi,
What other parameters of the instanced objects would you like to modify?

Thanks for trying to help, sorry for the late response I forgot to turn on “Notify me when a reply is posted”. We are doing it differently so we don’t have this problem anymore. We’re going to instance planes and change the texture depending on our data.
