Detailed Description

Describes a single instance of a node aka element in the Soft scene graph, relating it to the corresponding egg structures (e.g.

node, group, or table entry) that will be created.

Definition at line 46 of file softNodeDesc.h.

Member Function Documentation

int SoftNodeDesc::find_shape_vert ( LPoint3d  p3d,
SAA_DVector *  vertices,
int  numVert 
)

given a vertex, find its corresponding shape vertex and return its index.

Definition at line 928 of file softNodeDesc.cxx.

Referenced by make_vertex_offsets().

void SoftNodeDesc::force_set_parent ( SoftNodeDesc parent)

Sometimes, parent is not known at node creation As soon as it is known, set the parent.

Definition at line 135 of file softNodeDesc.cxx.

void SoftNodeDesc::get_joint_transform ( SAA_Scene *  scene,
EggGroup egg_group,
EggXfmSAnim anim,
bool  global 
)

Extracts the transform on the indicated Soft node, as appropriate for a joint in an animated character, and applies it to the indicated node.

This is different from get_transform() in that it does not respect the _transform_type flag, and it does not consider the relative transforms within the egg file. more added functionality: now fills in components of anim (EffXfmSAnim) class (masad).

Definition at line 513 of file softNodeDesc.cxx.

References EggXfmSAnim::add_component_data().

SAA_Elem * SoftNodeDesc::get_model ( ) const

Returns the SAA_Elem * associated with this node.

It is an error to call this unless has_model() returned true.
