I am learning how to draw object (shape) using opencv. I could draw circles with a specific color, but I don't know how to draw a circle with different color as shown in the picture.

Does anyone know how to draw this picture using opencv drawing function only. The shape does not have to be elips. It could be a circle or anything.

Thanks.

Read your link :

The example below shows something more interesting: Position and velocity are correlated.

and answer is here(from http://web.cortial.net/optim/annexe2....)

Now you can draw a gaussian and use warpperspective to rotate your image or draw a gaussian with phi(x,y) = gray level

Even though this is correct, why in the world would someone want to use OpenCV to draw visuals of a Gaussian distribution o_O?
