I3DProperties2 Interface

Provides additional access to members that control three-dimensional properties. Note: the I3DProperties2 interface has been superseded byI3DProperties3. Please consider using the more recent version.

Description

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.
