Hi ppl,
When I have the information such as the turning radius, the starting radian, the ending radian and the starting point, how do I trace out (render it into pixelated mode) an arc with the above information? This is interesting in comparison because a straight Line can easily achieved by D3DXVec2Lerp. Thanks
Jack

You'll have to discretize it into a series of straight segments. There's no such thing as a curved line primitive in graphics.
