This section describes the options shown on the Softimage-3D import converter
dialog box. Even though this dialog box has many fewer options than on its
export converter counterpart, it is this import
converter than contains the majority of the software's development effort.
Dialog Box Options
Location of Softimage Resource Directory
This option specifies the file path to the Softimage resource
directory. It is only needed when importing from a Softimage
scene file (it is not needed when importing from a single .hrc
file). If your installation of Softimage resides in "c:\soft"
then this filepath should be set to "c:\soft\3d\bin\rsrc". This
section will be grayed out if the input file is a Softimage .hrc
file and not a .dsc scene file.
Alternatively, the "Reset to "SI_LOCATION/3d/bin/rsrc" button can
be pressed which will set the directory to the assumed location
of the Softimage resources. NOTE that the global environment
variable 'SI_LOCATION' must point to the directory where your
Softimage installation resides. Please refer to the Softimage
installation guide for more information about this environment
Strip off Filepaths from Bitmap References
Normally all references to bitmap files within a Softimage file
use absolute filepaths (ie: "c:\pictures\tree.pic"). If this
option is disabled then the absolute filepath will be stripped
off from the bitmap references, else the filepaths will remain
List Softimage Geometric Entities Not Supported
If this checkbox is check-marked then all unsupported Softimage
entities (such as metaballs and spline curves) will be reported
to the message window.
Report Statistics About the Geometry File
If this checkbox is check-marked then parsing statistics will be
displayed in the message window after the Softimage file has been
Output Parsing Information to File 'debugsft.txt'
If this checkbox is check-marked then the contents of the
Softimage binary file will be verbosely described and output to
the file 'debugsft.txt'.
Display Curve/Face Control Point Locations
If this checkbox is check-marked then the control point (CV) locations used by any 3D independent NURBS or spline curves will be displayed. This is also applicable to FACE entities.
Display Bezier Curve/Face Handles
If this checkbox is check-marked then the tangent handles of 3D Bezier spline curves will be displayed (but only if the Display Curve/Face Control Point Locations option is also enabled) . This is also applicable to FACE entities.
Bump Mapping Intensity Divisor
This parameter affects the translation of a bump map's intensity.
Softimage uses a range of -20 to 20 as the bump mapping intensity
whereas this converter's internal database prefers values that
are much smaller (such as +-0.003). The numeric value in this
type-in box defines how much smaller the Softimage bump map
intensity will be scaled. Values from 100 to 300 produce bump
mapped images that look similar in Okino's NuGraf Rendering
System software to that rendered within Softimage.
The following checkboxes allow all or only some parts of the
Softimage .hrc file to be loaded:
If checkmarked, then load in all of the polygon mesh geometry.
If checkmarked, then load in all of the NURBS surface geometry.
NURBS Trim Curves
If checkmarked, then load in all of trim curve data that is
associated with each NURBS patch.
If checkmarked, then load in all of the bicubic patch geometry.
NURBS 3D Curves
If checkmarked, then load in all of the independent 3D NURBS curves. If this option is not visible then it has not yet been publicly released as a new importer option.
Spline 3D Curves
If checkmarked, then load in all of the independent 3D spline curves. If this option is not visible then it has not yet been publicly released as a new importer option.
If checkmarked, then load in the (single) camera from the
Softimage scene file (no cameras are stored within a .hrc file).
If checkmarked, then load in the lights.
If checkmarked, then load in the materials.
2D Material Textures
If checkmarked, then load in the textures that are referenced by
a Softimage material.
If checkmarked, then load in FACE entities. These are planar singular entities for which their exterior contours and optional interior holes are defined either by NURBS curves or via spline curves.
Convert Spline FACES to NURBS Faces
If checkmarked then any imported FACE entities which use spline curves will be converted to trimmed NURBS surfaces instead.
If checkmarked, object animation is imported from the Softimage scene file (no object animation data is stored within a .hrc file). Supported fcurves are: explicit location, explicit scaling and explicit rotation. Animation on a path is presently not supported.
If checkmarked, camera animation is imported from the Softimage scene file (no camera animation data is stored within a .hrc file). Supported fcurves are: explicit look-from, explicit look-at, the roll vector and the field of view. If the camera's field-of-view looks too narrow after importing into Okino's NuGraf or PolyTrans software, edit the animated camera and change the "Form Aspect Ratio Source" from "Stretch Horizontally" to "Stretch Vertically". Animation on a path is presently not supported.
