public interface I3DProperties3
Provides additional access to members that control three-dimensional properties.
This interface is new at ArcGIS 9.3. It supersedes I3DProperties and I3DProperties2.
I3DProperties3 introduces the AlphaThreshold property to get or set transparency thresholds for a layer.
The JPEG compression is the default compression type in memory and persistence. DXT is optional at runtime; it takes advantage of the graphic card capability and may improve runtime performance significantly.
TextureDownsamplingFactor (double type) ranges from 0.0 to 10.0, with 1.0 applying no down-scaling and 10.0 maximum down-scaling. The value set by the user will be snapped to the next lower power of 2 because OpenGL can only take a power of 2 number for the texture dimension. Generally, the larger the number, the more texture down-scaling, meaning coarser texture resolution, hence the better navigation performance, due to less memory consumption by textures.
