- _S_o_f_t_i_m_a_g_e_T_o_I_v converts 3D model files in Softimage version 2.6 model
- (.hrc) format into Open Inventor 2.0 files. Scene files are also handled,
- the default database settings are used or the database indicated by the
- -d flag. NURB curves and surfaces, polygons, hierarchy, textures,
- cameras and lights are converted into equivalent Open Inventor objects.
- Softimage NURB surfaces are converted into Open Inventor surfaces, which
- are then tesselated into polygons according to the object complexity
- setting. Try a lower complexity setting if performance is not as
- expected. For textures you need to convert the bitmap image used in the
- texture to an SGI .rgb file and place it in the same directory as the
- .hrc file. Copyright (c) Abaco Systems, Inc. 1995.

- Typically, _S_o_f_t_i_m_a_g_e_T_o_I_v expects a Softimage file to be specified on the
- command line after all command option switches. Because the interface to
- the Softimage file is done via the Softimage DBKit library, this
- translator cannot read from standard input (stdin) or write to standard
- output (stdout). _S_o_f_t_i_m_a_g_e_T_o_I_v messages are written to standard error
- (stderr).
-
- ----hhhh Prints a program usage message to standard error (stderr).
-
- ----ffff Use one normal for each face rather than one normal for each
- vertex when converting polysets.
-
- ----llll Use latest version of the given scene.
-
- ----mmmm Read a model file instead of a scene file.
-
- ----oooo Ignore cameras in Softimage file. This may make it easier to
- examine the models when loaded into ivview.

- The complexity setting to use in the Open Inventor file. The
- value ranges from 0.0 (lowest complexity) to 1.0 (highest
- complexity). The default is 0.5.
-
- ----dddd iiiinnnnppppuuuutttt____ddddbbbb
- Specifies the input database. The default is the first database
- in the DatabaseDir.rsrc file.

- If a knot_epsilon is specified, the knot vector will be scaled
- so that the knots are no closer together than knot_epsilon.
-
- ----iiii Inherit transformations from parent. This will not produce
- accurate results if the model uses inverse kinematics or
- constraints.

- 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.
-
- ----vvvv vvvveeeerrrrbbbboooosssseeee
- Provide feedback during the translator. 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 Softimage entities.
- -v 2 Print a summary of the applied
- options, a count list of the
- processed Softimage entities, and the
- name of each Softimage entity that is
- processed.
-
-
- <_i_n_f_i_l_e> Specifies the name of the file to read and convert to Open
- Inventor. Must be specified.
-
- <_o_u_t_f_i_l_e> Specifies the name of the Open Inventor file to use for output.
- Must be specified.

- 1. The triangulation algorithm still sometimes produces small or thin
- triangles which generate OpenGL errors. However, the errors are often not
- visually discernable.
-
- 2. There is a difference in how an offset looks in Softimage and Open
- Inventor. In Softimage, the base material shows through when the texture
- coordinates are off the texture map. In Open Inventor, the row of pixels
- on the boundary is repeated to the edge of the object. This may result in
- streaks. The texture can be repeated but it cannot flip orientation
- while it is being repeated.
-
- 3. Spherical and Cylindrical textures may not translate well.
