3D Shading

This tool enables you to control the appearance of all the 3D geometries in sliceOmatic. From this tool, you can also delete or save individual geometries.

Geometry List

This list enables you to select the geometry on which the other controls act. The yellow indicator on the surface’s button will be lit if the surface is visible (its shading is not “Off”).

 

Shading List

Select the shading you want to apply on the selected geometry. If the geometry is composed of polygons, the choices are:

 

Off

The surface is not shown

 

Line

The surfaces’ polygons are drawn as outlines

 

Flat

Each of the surface’s polygons is drawn with a color determined by its orientation with the light sources and the surface’s color.

 

Smooth

Colors are computed at the polygon’s vertices and interpolated on the polygon’s surface.

 

Note:

If the geometry is composed of points or lines, only the first 2 choices are available.

 

Delete Button

Delete the selected geometry.

 

Save Button

Save the selected geometry to a file. The surface saving dialog box will appear.

 

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.  SliceOmatic can create ".dxf" files, but it cannot read them.

 

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.  SliceOmatic can create ".dxf" files, but it cannot read them.

 

stl

&

stl_ascii

 

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.

 

obj

Wavefront OBJ file format.  A definition of the OBJ file format can be found in Wikipedia. SliceOmatic can create ".obj" files, but it cannot read them.

 

wrl

A VRML polygon file. A definition of the VRML file format can be found in Wikipedia. SliceOmatic can create ".wrl" files, but it cannot read them.

 

Color Edit

Change the selected geometry’s color (if the selected geometry has been recreated from a Tag, these controls will also change the Tag color).
