/*
|
|
* The activation function of the server is passed an LWObjectImport
|
|
* structure as its local data which includes the filename of the object
|
|
* to load. The loader attempts to parse the input file and calls the
|
|
* embedded callbacks to insert the data into LightWave. It indicates
|
|
* its success or failure by setting the 'result' field, and the optional
|
|
* failedBuf.
|
|
*
|
|
* result set by the server to one of the LWOBJIM values below.
|
|
*
|
|
* filename the filename of the object to load.
|
|
*
|
|
* monitor progress monitor that can be used to track the import
|
|
* process.
|
|
*
|
|
* failedBuf string buffer for the server to store a human-readable
|
|
* error message if the result code is LWOBJIM_FAILED.
|
|
*
|
|
* data private data pointer to be passed to all the embedded
|
|
* function callbacks.
|
|
*
|
|
* done called when object import is complete.
|
|
*
|
|
* layer start a new layer in the import data. The layer is
|
|
* defined by an index number and a name string.
|
|
*
|
|
* pivot set the pivot point for the current layer.
|
|
*
|
|
* parent set the index of the parent layer for the current layer.
|
|
*
|
|
* lFlags set the flag bits for the current layer. The low-order bit
|
|
* is set if this is a hidden layer.
|
|
*
|
|
* point add a new point to the current layer. The point is given
|
|
* by an XYZ position and the function returns a void pointer
|
|
* as point identifier.
|
|
*
|
|
* vmap select a VMAP for assigning data to points, creating a new
|
|
* VMAP if it does not yet exist. The VMAP is defined by a
|
|
* type, dimension and name.
|
|
*
|
|
* vmapVal set a vector for a point into the currently selected VMAP.
|
|
* The vector should have the same dimension as the VMAP.
|
|
*
|
|
* vmapPDV set a vector for a point with reference to a specific polygon.
|
|
* This is the "polygon discontinuous value" for the point.
|
|
*
|
|
* polygon add a new polygon to the current layer. The polygon is
|
|
* defined by a type code, type-specific flags and a list of
|
|
* point identifiers.
|
|
*
|
|
* polTag associate a tag string to the given polygon. The tag
|
|
* string has a type, the most common being 'SURF'.
|
|
*
|
|
* surface add a new surface to this object. The surface is defined by
|
|
* the base name, the reference name, and a block of raw surface
|
|
* data.
