Dust-File-Formats
-----------------------------------------------------------------
1. TDDD - this is the standard-format read and written by Dust
Features:
-all Attributes can be read, written, modified
-Imagine3.0-Textures and -Brushes can be read, written, modified
-every face has its own color (CLST)
-hard/soft edges will be treated correctly
-subgroups are supported
Restrictions:
-the reflection- and transluceny-parameters are taken from
the global atttributes (means: no RLST- and TLST-reading/saving)
2. LW (Lightwave) - very fast
Features:
-polygons are assumed to be convex and converted into triangles
-edge-optimizing optional, makes only sense if you
want to save the object as Imagine-Object later
-surfaces are converted into Imagine-Subgroups
-the DOUBLESIDED-flag can be set by the BACKFACES-parameter
-the specular level will be converted
-storing all textures/brushes/...
Restrictions:
-no lines (polygons with 2 points)
3. VS (Videoscape) - loading and saving is slow (ASCII-format)
Features:
-edge-optimizing optional, makes only sense if you
want to save the object as Imagine-Object
-Videoscape-colors are calculated as good as possible
-creation of backfaces if the BACKFACES-parameter is set
4. SPHERES - TDDD-Group-Objects made of real Spheres
This is a special particle-object-format (only for Imagine-users)
and can only be written.
5. PARTICLE - The fast DUST-Particle-Format
This Format consists of the particle- and the object-information
in TDDD-format. So all attributes are supported.
The LOAD-command automatically recognises the format, all object-saving
procedures (e.g. SAVE or MORPH) create objects in the format specified
by the SFORMAT-parameter.
NOTE: Dust converts LW-Surfaces into Subgroups and Subgroups into
LW-Surfaces - most of the object-converters (e.g. Vertex, Pixpro,
Castillian) aren't able to do that.
