• Anti-Aliasing Anti-Aliasing (AA) is a rendering technique designed to remove jagged edges, shimmering, and pixelation problems that are common in rendered 3D images. Rather than determining the color to display for each pixel by sampling a single location at the pixel's center, anti-aliasing samples multiple locations within each pixel and blends the results together to produce the final color. Anti-Aliasing can be set to favor either system processing performance or image quality, or the application can decide: • Setting for performance is best used when the 3D image is animated and smooth motion is the most important consideration. • Setting for quality is best used when highly detailed and realistic 3D objects is the most important consideration. • If you are unsure of how to configure anti-aliasing, use the Use application settings option. Your display will automatically adjust to the application's requirements. • Adaptive Anti-Aliasing Adaptive anti-aliasing is a technique that applies a combination of multi-sampling (MSAA) and super-sampling (SSAA) on 3D objects to improve edge smoothness and fine detail. This feature renders 3D objects containing transparencies more realistic, providing exceptional levels of image quality while maintaining performance. GV-R587 Series Graphics Accelerator - 22 Anisotropic Filtering .. .. Anisotropic Filtering is a technique that preserves detail on surfaces that have three-dimensional perspective and fade away into the background. It works best when used in conjunction with Mipmapping. Anisotropic Filtering can be set to favor either an increase in system processing performance or improved image quality: • Setting for performance is best used with applications that display objects with smooth, simple surfaces, like those seen in CAD applications. • Setting for quality is best used with applications that display highly detailed scenes, backgrounds, and textured objects, like those seen in 3D games. • If you are unsure how to configure anisotropic filtering, use the Use application settings option. Your display will automatically adjust to the application's requirements. CATALYST® A.I. Catalyst® A.I. makes use of ATI's new texture analyzer technology to optimize performance in 3D applications while maintaining or even improving image quality. It analyzes individual textures as they are loaded to determine the best and fastest way to display them. .. Mipmap Detail Level Mipmapping is a texturing technique that preserves the detail on a 3D object's surface as it moves into the background. A series of low- and high-resolution texture maps are stored in memory and selectively used to create the object's surface, depending on what level of detail is needed. Mipmap detail level can be set to favor either an increase in system processing performance or improved image quality: • Setting for performance is best used when the 3D image is animated and smoothness of motion is the most important consideration. • Setting for quality is best used when high surface detail is required, especially if the animated object rotates or moves into the background. - 23 -Software Installation • All Settings The All Settings page combines all of the principal 3D features onto a single page, without any preview window, allowing for quick access and adjustment. This page is useful when it is not necessary to preview the adjusted settings because the effect is already known or understood. • More Settings Use the More Settings dialog to select settings for the Direct 3D and OpenGL Application Programmable Interfaces (API). These settings are provided for resolving certain incompatibilities within 3D applications that use one of these APIs. Use this dialog when you know which type of API (Direct 3D or OpenGL your 3D application uses, and you want to select a particular API-specific feature. If you are not sure which API your 3D application uses, consult the documentation of your 3D application. Note: The Alternate Pixel center Direct 3D setting is not supported on systems running Windows Vista. This setting corrected a corruption problem that occurred with some older games that should not occur with modern games. Color: Adjust the overall richness of color by using the Gamma control. To adjust the overall brightness use the Brightness control, and the overall contrast use the Contrast control. GV-R587 Series Graphics Accelerator - 24 AvivoTM Video: • Presets To quickly adjust your video settings choose one of the video presets. Note: These settings will only affect applications with video overlay support. • Basic Color Use the Avivo Color: Basic option to manually set Gamma, Brightness, Contrast, Saturation, and Tint for video playback. Note: Certain video formats do not support these adjustments. These settings will only affect applications with video overlay support. • Advanced Color Use the Advanced Color page to fine tune the color of standard definition video (720x480) to make the color more or...
