Hello,

I've bought a new computer with a new graphics card. But I have some
problems with anti aliasing in the OpenGL view in Realsoft3D. It
doesn't work or produce garbage in the rendering, depending of the
anti aliasing setting in the driver.

My Hardware:
  Intel Core2Duo 6300
  1 GB Mainmemory
  ATI Radeon X1650 with 256 MB Ram

Software:
  Windows XP SP2
  Realsoft3D 5.1 SP3
  Display-Driver (latest):
  Treiber-Paketversion    8.33-061220m-040997C-ATI
  Catalyst® Version       07.1
  Anbieter        ATI Technologies Inc.
  2D-Treiberversion       6.14.10.6660
  Direct3D-Version        6.14.10.0464
  OpenGL-Version  6.14.10.6287
  Catalyst® Control Center-Version        1.2.2545.38916

The problem and the recreation of it:
In the Catalyst Control Center under "3D -> Anti-Aliasing" I checked
the option "Let the application decide". Starting up Realsoft3D and
just creating an analytical sphere in an OpenGL view. Ok, works, but
no anti aliasing. In the view settings I check "Smoothen lines". But
this only smoothes the lines of the axis and the lines of the ground
grid, but not the edges of the sphere. Clicking on Render renders
nicely.

In the Catalyst Control Center under "3D -> Anti-Aliasing" I uncheck
now the option "Let the application decide". Back in Realsoft3D
nothing happens. Now I switch to Wireframe mode and then back to
OpenGL view mode. A window pops up with the following text:

setPixelformat() failed 183
(Error:r3dcogl:1853)
SetPixelFormat failed
(Error:r3opengl:315)

Clicking OK and the window disapears. But no anti aliasing. Clicking
on Render produces again this window and displays a nice rendering.

Now I restart Realsoft3D. I directly see anti aliased lines. I create
an analytical sphere in OpenGL view and the egdes are anti aliased.
Looks nice. No error window. But, if I click now on Render, I get
garbage. The OpenGL view is overlayed with small blocks of graphic
fragments. If I click somewhere, the garbage disappears and I have my
anti aliased OpenGL view back.

If I swith to wire frame view and then on Render, I get a nice
rendering without errors.

What's going on here? Is there a solution?

Best regards,
Yogi Marc Michael
