Hello

I want to implement a Polar Display, in principle similar to the drawPartitialDisk function.
I need round about 1300 cells (called one burst) from the center to the outside and I want to be able to set the color of each cell. The display has to draw about 200 of those bursts ..

My first idea is to store each burst in a VBO and draw it by using glDrawElements(GL_QUADStrip ..
I have no experience and my questions are

is this possible with VBO´s ?
Can I change dynamically the color of one burst while the others are drawn ?

I´m thankful for each hint or a better idea ?
thanks
