Describes a complete tree of maya nodes for conversion.
void reset_sliders()
Resets all of the sliders associated with all blend shapes down to 0.
EggGroup * get_egg_group(MayaNodeDesc *node_desc)
Returns the EggGroupNode corresponding to the group or joint for the indicated node.
void clear()
Resets the entire tree in preparation for repopulating with a new scene.
MayaNodeDesc * get_node(int n) const
Returns the nth node in the hierarchy, in an arbitrary ordering.
bool ignore_slider(const std::string &name) const
Returns true if the indicated name is on the list of sliders to ignore, false otherwise.
void tag_joint_all()
Tags the entire hierarchy for conversion.
bool tag_named(const GlobPattern &glob)
Tags nodes matching the indicated glob (and all of their children) for conversion.
MayaNodeDesc * build_node(const MDagPath &dag_path)
Returns a pointer to the node corresponding to the indicated dag_path object, creating it first if ne...
EggXfmSAnim * get_egg_anim(MayaNodeDesc *node_desc)
Returns the anim table corresponding to the joint for the indicated node.
void report_ignored_slider(const std::string &name)
Outputs a message to the user reporting that a slider was ignored.
EggTable * get_egg_table(MayaNodeDesc *node_desc)
Returns the EggTable corresponding to the joint for the indicated node.
bool tag_selected()
Tags the just the selected hierarchy for conversion, or the entire hierarchy if nothing is selected.
int get_num_nodes() const
Returns the total number of nodes in the hierarchy, not counting the root node.
void clear_egg(EggData *egg_data, EggGroupNode *egg_root, EggGroupNode *skeleton_node, EggGroupNode *morph_node)
Removes all of the references to generated egg structures from the tree, and prepares the tree for ge...
MayaBlendDesc * get_blend_desc(int n) const
Returns the nth MayaBlendDesc object discovered in the tree.
bool tag_joint_named(const GlobPattern &glob)
Tags nodes matching the indicated glob (and all of their children) for conversion.
MayaBlendDesc * add_blend_desc(MayaBlendDesc *blend_desc)
Adds the indicated MayaBlendDesc object to the list of blends collected so far.
EggSAnimData * get_egg_slider(MayaBlendDesc *blend_desc)
Returns the anim table corresponding to the slider for the indicated blend.
bool build_hierarchy()
Walks through the complete Maya hierarchy but does not tag any nodes for conversion.
bool untag_named(const GlobPattern &glob)
Un-tags nodes matching the indicated glob (and all of their children) for conversion.
int get_num_blend_descs() const
Returns the number of unique MayaBlendDesc objects (and hence the number of morph sliders) discovered...
