Model Viewer is an application that takes up to 3 command-line parameters:
model_viewer [api_impl] transmittal_file_location [-nt|-nm]
The <transmittal_file_location> parameter is mandatory, and specifies
the transmittal to be loaded.
The <api_impl> parameter is optional, specifying which implementation
of the SEDRIS API should be used to read the transmittal, if dynamic binding
was used to compile the executable of the application. See the documentation
on API implementations for further discussion of this parameter. For the
SEDRIS Transmittal Format (STF) implementation, either "stf" or
"STF" can be specified.
The -nt and -nm parameters are optional, and mutually exclusive. (If both
were provided, the user would be instructing Model Viewer to omit both
textures and models from display, i.e., to display nothing.)
If provided,
the -nt parameter indicates that texture information is to be omitted during
the loading and display of the contents of the transmittal's
<Model Library>. Neither the
<Image Library>, if
present, nor any texture mapping information will be loaded or displayed.
Any
<Image Mapping Functions>,
<Texture Coordinates>,
and / or <Tack Points>
present in the transmittal will be ignored.
Conversely, the -nm parameter, if provided, indicates that model information
is to be omitted after the loading and display of the contents of the
transmittal's
<Image Library>.
The text window displays information about the
<Image> and
<Model> instances being loaded from the SEDRIS transmittal,
together with any errors or warnings. Once the
<Image> and
instances are loaded, the viewer will open the
*3D-view* window and proceed to step through all the
<Image> instances loaded, in sequence, displaying them as
they are loaded. After each
<Image> has been displayed,
the first "root"
<Model> in the transmittal's
<Model Library>
will be displayed. The window will then await user control
from the keyboard.
