Using floats to draw 2d?

Is there a float version of the draw2d functions?
I use to use popcap and they had a float version of their draw functions for smoother drawing, noticed the difference when i ported some of my game code over to irrlicht.
If none, any ideas on how to draw 2d images/polygons smoother?

Setup an orthogonal camera and draw them in 3d space.

Well, subpixel positioning? Just calculate positions on your own, and draw where you think it should end. You cannot get better precision than per pixel.

Would like to solve the problem in 2d if possible first.
As for the pixel suggestion, possible i could get a code example?
This is what i currently do to draw a circle.
The variable "m_vPos" is a vector2df.
Do you mean calculate the 15 points using x = cos(angle), y = sin(angle)?
If so how would that be any smoother? as the drawPixel function paramaters are u32.
Code: Select all
g_pApp->GetVideoDriver()->draw2DPolygon(core::position2d<s32>(m_vPos.X,m_vPos.Y),m_fRadius,m_Color,15);

Well, the thing is that the minimal unit you can use is that of a pixel. You cannot go beyond that (in 2d) without major overhead. But you can use 3d and position arbitrarily.

Ok, i will do it in 3d, thanks
