Drawing a 2D Circle

-Moxie- · 2002-08-28T13:42:56

How would you create a 2D circle (I guess it would be a 3d cilinder with no Z hieght)? How many verticies do you need for it to looks smooth? How do you calculate the coords for the verticies rather than hardcoding? Or, is this generally done with a rectangular panel and a texture with transparency (sort of like a sprite) Direct3D code snippet appreciated. [edited by - -Moxie- &#111n August 26, 2002 1:08:32 PM]

It might be easier to model your pieces. Direct3D has built in support for the .x format, so it is pretty easy to load them.
