Camera Determines the viewpoint used for the scene in Director. This option defaults to Active Viewport, but if any cameras exist in the scene, you can choose one from the drop-down list. NOTE In order to preview or export an animated camera, you must select that camera from the list. Selecting Active Viewport with an animated camera will not export that camera's animation. Compression Settings group The Shockwave 3D file contains all scene assets in a proprietary compressed and streaming format. You can control the order in which data streams with the user properties. The amount of compression of the scene assets is set by three controls: Geometry Quality, Texture Quality, and Animation Quality. The controls have values that range from 0.1 to 100.0, with higher values giving less compression and better quality (a more faithful representation of the original model). A value of 100 means that the scene assets will be represented at the best quality possible, but with some degree of compression still present. It does not represent the value at which compression does not occur. Also, the compression controls do not have a linear scale, so a setting of 20.0 doesn't necessarily mean that the quality level of the resulting data is twice as good as that produced with a setting of 10.0. Geometry quality Controls how much the scene geometry data (such as vertex positions and normals and texture coordinates) is compressed. The default of 25.0 generally produces a good compromise between data accuracy and space savings. Texture quality Controls the compression of textures (images) in the scene. Animation quality Controls the compression of animation data in the scene. Higher compression levels (lower quality) tend to remove the finer motions authored in the scene, especially motion-capture data, while occasionally introducing small noise artifacts. NOTE You might need to use larger values of the Animation Sampling Interval control on page 7271 (below) along with greater values of this setting to minimize the file space consumed by animation while still maintaining acceptable motions. Texture Size Limits group The Texture Size Limits setting lets you reduce the size of the W3D file by limiting the size of the texture maps in the export. 7270 | Chapter 23 Managing Scenes and Projects
