- _A_l_i_a_s_T_o_I_v converts 3D model files in Alias wire format (versions 5.0,
- 5.0.1, 5.1, and 5.1.1) into Open Inventor 2.0 files. NURB curves and
- surfaces, polygons, hierarchy, textures, cameras and lights are converted
- into equivalent Open Inventor objects. Alias NURB surfaces are converted
- into Open Inventor surfaces, which are then tesselated into polygons
- according to the object complexity setting. If perfomance is not
- satisfactory on the model, try a lower complexity setting. For textures,
- convert the bitmap image used in the texture to an SGI .rgb file and
- place it in the same directory as the wire file. Use the convenience
- function ffffrrrroooommmmaaaalllliiiiaaaassss to convert Alias .pix bitmap files into .rgb files.

- Typically, _A_l_i_a_s_T_o_I_v expects an Alias file to be specified on the command
- line after all command option switches. If no wire file is specified on
- the command line, _A_l_i_a_s_T_o_I_v will read from standard input (stdin). By
- default, _A_l_i_a_s_T_o_I_v writes the converted data to standard out (stdout) and
- messages to standard error (stderr).
-
- ----hhhh Prints a program usage message to standard error (stderr).
-
- ----oooo Ignore cameras in the Alias file. This may make it easier to
- examine the models in ivview.
-
- ----ffff Use one normal for each face rather than one normal for each
- vertex when converting polysets.
-
- ----nnnn Convert all the trimming curve control vertices to non-
- rational. Try this if some of the trimmed surfaces are not
- displaying correctly.
-
- ----pppp Convert all trimming curves such that the first and last
- control vertices are interpolated. Try this is some of the
- trimmed surfaces are not displaying correctly.

- The complexity setting to use during the conversion to
- Inventor. The value ranges from 0.0 (lowest complexity) to 1.0
- (highest complexity). The default is 0.5.

- The texture quality setting to use in the Open Inventor file.
- The value ranges from 0.0 (lowest complexity) to 1.0 (highest
- complexity). The default is 0.1.

- Provide feedback during the translation. Valid values are:
- -v 0 Do not print any summary. This is the
- default value.
- -v 1 Print a summary of the applied options
- and a count list of the processed Alias
- entities.
- -v 2 Print a summary of the applied options,
- a count list of the processed Alias
- entities, and the name of each Alias
- entity that is processed.
-
-
- <_i_n_f_i_l_e> Specifies the name of the file to read and convert to Open
- Inventor. If "----" is specified instead of a filename, input
- will be read from
- standard input (stdin). If no file name is specified, the
- program will be read from standard input (stdin) and output
- will be written to standard output (stdout).
-
-
- <_o_u_t_f_i_l_e> Specifies the name of the Open Inventor file to use for output.
- If no file is specified, the program will output to standard
- output (stdout).

- 1. LIMITATIONS
- Texture
- 1. Every texture map is assumed to be
- a color texture map.
- 2. Only the first texture attached to
- a shader is converted.
- 3. Procedural textures are not converted.
-
- Shaders
- 1. Only the first shader attached to a
- surface or face is converted.
-
- Lights
- 1. If a surface or face was linked to an
- exclusive light it will be illuminated
- by both that light and all non-exclusive
