I came up with my own code that draws a circle. I think it works by rotating the circle so there will be pixels write overlap.
Code: Select all
void D3DGraphics::DrawCircle( int cx, int cy, int rad, int r, int g, int b )
{
float radSqr = rad * rad;
for( int x = -rad; x <= rad; x++ )
{
int y = sqrt( radSqr - x*x ) + 0.5f;
PutPixel( cx + x , cy + y ,r,g,b);
PutPixel( cx + x ,(cy - y ) ,r,g,b);
PutPixel( cx + y , cy + x ,r,g,b);
PutPixel((cx - y), cy + x ,r,g,b);
}
}
