fsaaviewer D3D FSAA Viewer is a tool to examine the Antialiasing sampling pattern used by 3D Accelerator cards. Its an old program that I wrote, that has been very useful for a lot of people, in particular when reviewing graphics cards. Expand the post for download links.

How It works

In words D3D FSAA Viewer works by drawing regularly spaced subpixel sized quads that are fractionally more than a single pixel apart.

For the geometry mode the quads are made out of 2 triangles, and the texture mode the quads are a region in a texture.

The following two images shows how D3D FSAAViewer works. The image represents a ‘zoomed’ in view of the boxes that D3D FSAAViewer draws if it was running using a 8×8 grid and 1/4 point size.
The blue boxes represents pixel edges.
The yellow squares represent the quads that D3D FSAAViewer draws.
The red dots are the pixel sampling positions used by the graphics card.
The green filled regions are the pixels that are drawn on screen.
