3D User Interfaces and 3D App Building Using the Chrome Library Set of Behaviors

Setting Up Hardware Anti-Aliasing (FSAA)

If your 3D graphics card is Direct X compliant and is capable of hardware anti-aliasing (Full Screen Anti-Aliasing), you can activate it on your Shockwave 3D scene using the Chrome Lib. Even entry-level graphics cards such as the ATI Radeon 7000 are now endowed with FSAA under DirectX 7, so you can easily benefit from this feature. However, hardware anti-aliasing is only available with Director MX 2004 and version 10 of Macromedia Shockwave Player.

  1. Drag and drop the Anti-Aliasing behavior from the Chrome Lib onto the W3D sprite, either on the Stage or in the Score. The following dialog box appears:

  3. Check the Hardware Anti-Aliasing box. Click OK.
  4. Click the Play button in the Control panel or press Enter to start the movie. The scene is now anti-aliased and looks much better.

Not only does hardware anti-aliasing improve rendering quality—it doesn't slow rendering speed as is the case with software anti-aliasing. For hardware anti-aliasing, the graphics card GPU (Graphics Processing Unit) wires this function. For software anti-aliasing, it is the computer's CPU that does all the required computation, hence the slowdown.
