Detailed Description
This class supervises the construction of an EggData structure from a single Maya file, or from the data already in the global Maya model space.
Note that since the Maya API presents just one global model space, it is not possible to simultaneously load two distinct Maya files.

Member Function Documentation
◆ add_exclude()
| void MayaToEggConverter::add_exclude | ( | const GlobPattern & | glob | ) |
Adds a name pattern to the list of excluded nodes.
Definition at line 262 of file mayaToEggConverter.cxx.
◆ add_force_joint()
| void MayaToEggConverter::add_force_joint | ( | const GlobPattern & | glob | ) |
Adds a name pattern to the list of force_joints.
Any DAG node that matches a name on the list will be treated as if it were a joint during the conversion process; it will receive animation and position information. Normally, a true Maya joint, as well as any DAG nodes whose transforms are animated, will automatically be flagged as a Panda joint.
Definition at line 322 of file mayaToEggConverter.cxx.
◆ add_ignore_slider()
| void MayaToEggConverter::add_ignore_slider | ( | const GlobPattern & | glob | ) |
Adds a name pattern to the list of ignore_sliders.
Any slider (blend shape deformer) that matches a name on the list will not be converted or otherwise molested by the converter. This is occasionally necessary to filter out automatically-created sliders that are not intended to be used directly, but instead have an indirect effect on other sliders.
Definition at line 283 of file mayaToEggConverter.cxx.
◆ add_subroot()
| void MayaToEggConverter::add_subroot | ( | const GlobPattern & | glob | ) |
Adds a name pattern to the list of subroot nodes.
If the list of subroot nodes is not empty, then only a subroot of the nodes in the maya file will be converted: those whose names match one of the patterns given on this list.
Definition at line 226 of file mayaToEggConverter.cxx.
◆ add_subset()
| void MayaToEggConverter::add_subset | ( | const GlobPattern & | glob | ) |
Adds a name pattern to the list of subset nodes.
If the list of subset nodes is not empty, then only a subset of the nodes in the maya file will be converted: those whose names match one of the patterns given on this list.
Definition at line 246 of file mayaToEggConverter.cxx.
◆ clear()
| void MayaToEggConverter::clear | ( | ) |
Frees all of the Maya pointers kept within this object, in preparation for loading a new scene or releasing the Maya API.

Definition at line 235 of file mayaToEggConverter.cxx.
◆ close_api()
| void MayaToEggConverter::close_api | ( | ) |
Closes the Maya API, if it was previously opened.
Caution! Maya appears to call exit() when its API is closed.

virtual |
Returns the English name of the file type this converter supports.
