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.

bool MayaToEggConverter::convert_file (  const Filename &  filename  )  [virtual]

bool MayaToEggConverter::convert_flip (  double  start_frame,
double  end_frame,
double  frame_inc,
double  output_frame_rate
)  [private]
 

Converts the animation as a series of models that cycle (flip) from one to the next at the appropriate frame rate.

This is the most likely to convert precisely (since we ask Maya to tell us the vertex position each time) but it is the most wasteful in terms of memory utilization (since a complete of the model is stored for each frame).

Returns the EggGroup corresponding to the indicated fully-qualified Maya path name.

If there is not already an EggGroup corresponding to this Maya path, creates one and returns it.

In this way we generate a unique EggGroup for each Maya node we care about about, and also preserve the Maya hierarchy sensibly.

void MayaToEggConverter::make_locator (  const MDagPath &  dag_path,
const MFnDagNode &  dag_node,
EggGroup *  egg_group,
EggGroupNode *  egg_root
)  [private]
 

Locators are used in Maya to indicate a particular position in space to the user or the modeler.

We represent that in egg with an ordinary Group node, which we transform by the locator's position, so that the indicated point becomes the origin at this node and below.

const MFnNurbsCurve &  curve,

EggGroupNode *  egg_root
)  [private]
 

Converts the indicated Maya NURBS curve (a standalone curve, not a trim curve) to a corresponding egg structure and attaches it to the indicated egg group.

Definition at line 1301 of file mayaToEggConverter.cxx.

void MayaToEggConverter::make_nurbs_surface (  const MDagPath &  dag_path,
MFnNurbsSurface &  surface,

Converts the indicated Maya NURBS trim curve to a corresponding egg structure, and returns it, or NULL if there is a problem.

Definition at line 1212 of file mayaToEggConverter.cxx.

bool MayaToEggConverter::open_api (   ) 
 

Attempts to open the Maya API if it was not already open, and returns true if successful, or false if there is an error.

bool MayaToEggConverter::process_chan_node (  const MDagPath &  dag_path,
EggGroupNode *  egg_root
)  [private]
 

Similar to process_model_node(), but this code path is followed only when we are building a table of animation data (AC_chan).

It just builds up the EggTable hierarchy according to the joint table.

bool MayaToEggConverter::process_model_node (  const MDagPath &  dag_path,
EggGroupNode *  egg_root

Converts the indicated Maya node (given a MDagPath, similar in concept to Panda's NodePath) to the corresponding Egg structure.

Returns true if successful, false if an error was encountered.

EggGroup * MayaToEggConverter::r_get_egg_group (  const string &  name,
const MDagPath &  dag_path,
EggGroupNode *  egg_root

The recursive implementation of get_egg_group().

Definition at line 1810 of file mayaToEggConverter.cxx.

bool MayaToEggConverter::reparent_decals (  EggGroupNode *  egg_parent  )  [private]
 

Recursively walks the egg hierarchy, reparenting "decal" type nodes below their corresponding "decalbase" type nodes, and setting the flags.

Returns true on success, false if some nodes were incorrect.

Definition at line 2189 of file mayaToEggConverter.cxx.

void SomethingToEggConverter::set_animation_convert (  AnimationConvert  animation_convert  )  [inline, inherited]
 

Specifies how source animation will be converted into egg structures.

The default is AC_none, which means animation tables will be ignored. This is only meaningful for converters that understand animation.

Definition at line 93 of file somethingToEggConverter.I.

void SomethingToEggConverter::set_character_name (  const string &  character_name  )  [inline, inherited]
 

Specifies the name of the character generated.

This name should match between all the model and channel egg files for a particular character and its associated animations.

void SomethingToEggConverter::set_egg_data (  EggData *  egg_data,
bool  owns_egg_data
)  [inherited]
 

Sets the egg data that will be filled in when convert_file() is called.

This must be called before convert_file(). If owns_egg_data is true, the egg_data will be deleted when the converter destructs. (We don't use the reference counting on EggData, to allow static EggDatas to be passed in.)

void SomethingToEggConverter::set_end_frame (  double  end_frame  )  [inline, inherited]
 

Specifies the ending frame of the animation to convert, in the units specified by set_input_frame_rate().

If this is unspecified, the ending frame is taken from the source, for instance from the last frame of the animation slider.

void SomethingToEggConverter::set_frame_inc (  double  frame_inc  )  [inline, inherited]
 

Specifies the increment between frames to extract.

This is the amount to increment the time slider (in units of internal_frame_rate) between extracting each frame. If this is not specified, the default is taken from the animation package, or 1.0 if the animation package does not specified a frame increment.

void SomethingToEggConverter::set_input_frame_rate (  double  input_frame_rate  )  [inline, inherited]
 

Specifies the number of frames per second that is represented by the "frame" unit in the animation package.

If this is omitted, it is taken from whatever the file header indicates. Some animation packages do not encode a frame rate, in which case the default if this is omitted is the same as the output frame rate.

void SomethingToEggConverter::set_merge_externals (  bool  merge_externals  )  [inline, inherited]
 

Sets the merge_externals flag.

When this is true, external references within the source file are read in and merged directly; otherwise, only a reference to a similarly-named egg file is inserted.

void SomethingToEggConverter::set_output_frame_rate (  double  output_frame_rate  )  [inline, inherited]
 

Specifies the number of frames per second that the resulting animation should be played at.

If this is omitted, it is taken to be the same as the input frame rate.

Replaces the PathReplace object (which specifies how to mangle paths from the source to the destination egg file) with a new one.

Specifies the starting frame of the animation to convert, in the units specified by set_input_frame_rate().
