SoftimageToIv - convert a Softimage .hrc file to Open Inventor 2.0 format
Showing IRIX 6.5.19. Unchanged since IRIX 6.5.
NAME SoftimageToIv - convert a Softimage .hrc file to Open Inventor 2.0 format SYNOPSIS SoftimageToIv [-h] [-m] [-l] [-o] [-f] [-i] [-d input_db] [-c object_complexity] [-t texture_quality] [-k knot_epsilon] <infile> <outfile> DESCRIPTION SoftimageToIv 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. Command Line Options Typically, SoftimageToIv 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). SoftimageToIv messages are written to standard error (stderr). -h Prints a program usage message to standard error (stderr). -f Use one normal for each face rather than one normal for each vertex when converting polysets. -l Use latest version of the given scene. -m Read a model file instead of a scene file. -o Ignore cameras in Softimage file. This may make it easier to examine the models when loaded into ivview. -c complexity 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. -d input_db Specifies the input database. The default is the first database in the DatabaseDir.rsrc file. -k knot_epsilon If a knot_epsilon is specified, the knot vector will be scaled so that the knots are no closer together than knot_epsilon. -i Inherit transformations from parent. This will not produce accurate results if the model uses inverse kinematics or constraints. -t texture_quality 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. -v verbose 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. <infile> Specifies the name of the file to read and convert to Open Inventor. Must be specified. <outfile> Specifies the name of the Open Inventor file to use for output. Must be specified. KNOWN BUGS 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.
