How can I darw a filled polygon with J2ME?
Either write you own method, to do this:
Or use the nokia extension in: DirectGraphics
void drawPolygon(int xPoints, int xOffset, int yPoints, int yOffset, int nPoints, int argbColor);
Probably won't be very fast though either way.
Better bet might be to have a look for some of the 3D engines people have already created for phones.
