Is there a way to draw a bitmap with transparencies in a 3d world without describing the bitmap object in vectors? What I mean is I have been drawing some bitmaps to simple planes, the bitmaps are 40px X 20px and are of a character, a little man. Around the edges of the character there are transparent pixels that when drawn to a canvas remain transparent, but when drawn to the simple plane get filled in with black, is there a way to draw my character with opengl without describing the specific outlines of the character in vectors?
