Maths question

Recommended Posts

Can someone explain how you would work out points on a circle.

Lets say I have an imaginary circle in the middle of my screen and I want to have 10 points all equally spaced around the circle. How do I work this out.

I know the diameter of the circle and from that you can times it by Pi to get the circumfrance of the circle.

You could then work out what distance around the circle the points need to be but I'm not sure how you translate this in to pixel positions.

I assume that you would have to relate it to the position of the center pixel but that's as much as I know.

I can't remember back to my school days unfortunately.
