If I do dbCirlce it makes a circle but it doesn't fill the circle with a color. All i want is white. How would I do this?

Not easily. I tried this once by using drawing multiple circles from radius 1 up to the radius I wanted. Unfortunately, due to precision issues there were some pixels that never got drawn. You might try a blur on the bitmap but that really takes CPU cycles. Or used dbDot() to fill it in.

Ultimately I covered the issue by creating my own Image class which directly manipulates the Direct X image and wrote my own circle and ellipse routines that optionally fill the primitive.

I'd recommend filling in with dbDot()

Or, loop through the diameter of your sphere and draw horizontal lines at each step, but change the width of each line base on sin(currentYPercentage(0-1 range)*PI2).
