B: The System DLLs

 

 

SliceO_System\3D.dll

 

System Variables defined in this library:

 

 

$GEOM_TAG_NB

(I32,R)

Number of potential 3D geometries created from TAG data (through modes such as (Contour Line, or Shell). (= $TAG_NB)

 

 

$GEOM_FILE_NB

(I32)

Number of 3D geometries not created from TAG (probably imported in sliceOmatic from a 3D format such as MOVIE.BYU).

 

 

Commands recognized in this library:

 

Geom: t_surf Write (mov|dxf|stl|stl_ascii|obj) file_name

Write all the geometries matching the template "t_surf" to the file "file_name" using the selected file format. The available formats are:

 

mov

Movie.BYU format.  This old polygon format, developed by Brigham Young University for their MOVIE.BYU program in the 80's, is very simple, which makes it ideal to store simple polygonal objects such as those created in sliceOmatic.  The format is described in more detail in appendix E

 

dxf

Autocad file format.  The geometries will be saved using the POLYLINE primitives.  A definition of the DXF file format can be found in Wikipedia.

 

stl

Stereolithography file format (binary version and ASCII versions).  A definition of the STL file format can be found in Wikipedia.

 

Note:

STL format can only describe 1 object.  If multiple objects are selected, sliceOmatic will create 1 file per object.

 

 

stl_ascii

 

obj

Wavefront OBJ file format.  A definition of the OBJ file format can be found in Wikipedia.

 

Geom: t_surf Delete

Delete all the geometries matching the template "t_surf".
