How to issuse aliasing when make 3D Mapping ?

[whdt]

I make a 3d Mapping test.

but the aliasing of  projection screen is very serious.

I have not found where to adjust anti aliasing in WO.

Please help me.

Thank you very much.

I am also interested to learn if there is any solve for this??

Looking at this image specifically, it looks like projector placement/throw is to blame here. Increase the physical layer resolution covering that surface area and you should see improvements.

Are you referring mainly to the edge of the image?

 

Do you apply the image directly to the 3D geometry, or through a virtual display?

Hey Mike,

 

Yes mainly the edge with the steppy aliased line.

 

I am going through a Virtual Display. Does that effect it?

 

Thanks

You can enable anti-aliasing in your graphics card settings. Choose to override the application's settings and select multi-sampled anti-aliasing (MSAA). I did some quick tests. This is without AA (click to enlarge):

 

 

This is with MSAA x8:

While Miro's solution is very good, it is more taxing for the hardware, so make sure you re-test before going on site, to make sure everything still plays as expected. Another trick to improve this a bit, if you're rendering through a virtual display, is to make the virtual display two pixels wider and taller than the content you're playing on the surface. This trick assumes the content is just played as is, and doesn't move about or extend outside the virtual display. Place the content centered on the virtual display, leaving a 1 pixel "transparent" border of pixels all around. This should take off the jaggies, at the expense of the image not extending all the way to the edge of the 3D geometry (due to this "one pixel off" trick). Since the edge pixels are transparent, you'll get antialiasing between those and the edge pixels of the content.
