Rigid Vertex Interface

A rigid vertex is represented by an instance of IPhyRigidVertex.

• IPhyRigidVertex::GetNode() - Returns a pointer to the INode to which the given vertex is assigned (controlled).
• IPhyRigidVertex::GetOffsetVector() - Returns a Point3 offset vector in the local coordinate space of the nth INode.

Blended Rigid Vertex Interface

A blended rigid vertex is represented by an instance of IPhyBlendedRigidVertex.

• IPhyBlendedRigidVertex::GetNumberNodes() - Return an int value which specifies how many nodes (Physique Links) this vertex is assigned to. The deformation of this vertex will be a blended (weighted average).
• IPhyBlendedRigidVertex::GetNode() - Return a pointer to the nth INode to which the given vertex is assigned (controlled).
• IPhyBlendedRigidVertex::GetOffsetVector() - Return a Point3 offset vector in the local coordinate space of the nth INode.
• IPhyBlendedRigidVertex::GetWeight() - Return a floating point weight for the nth INode.

Physique Export Interface

The physique export interface is represented by an instance of IPhysiqueExport. It is accessed from a physique modifier using a call to Animatable::GetInterface() with the class ID I_PHYINTERFACE.

• IPhysiqueExport::GetContextInterface()- Returns a ModContext Export Interface for the ModContext associated with the given INode.
• IPhysiqueExport::ReleaseContextInterface() - Must be called to free the context interface from memory.
• IPhysiqueExport::GetInitNodeTM() - Returns the node transformation matrix in the initial position given a node pointer. Passing a node pointer for the deformable object itself will return the object offset matrix at the initial position, instead of the node transformation matrix. The return values are one of the following:
• • MATRIX_RETURNED
  • NODE_NOT_FOUND
  • NO_MATRIX_SAVED
  • INVALID_MOD_POINTER
• MATRIX_RETURNED
• NODE_NOT_FOUND
• NO_MATRIX_SAVED
• INVALID_MOD_POINTER
• IPhysiqueExport::Version() - Returns the version of the export interface. For physique 2.2 the return value is 22.
• IPhysiqueExport::SetInitialPose() - Puts the model in/out the initial position. Passing TRUE puts the model in the initial pose, Passing FALSE allows the model to deform normally.

Physique Context Export Interface

The physique context export interface is represented by an instance of IPhysiqueContextExport. A pointer to IPhysiqueContextExport can be retrieved using the method IPhysiqueExport::GetContextInterface(). The context Interface is associated with a physique modifier associated with a node.

• IPhysiqueContextExport::GetNumberVertices() - Returns the number of vertices for the given physique object.
• IPhysiqueContextExport::ConvertToRigid() - When called with the value TRUE as an argument, all vertices accessed by IPhysiqueContextExport::GetVertexInterface() will be converted to rigid vertices. If passed the value FALSE as an argument, then any deformable vertices will return NULL when retrieved using IPhysiqueContextExport::GetVertexInterface().
• IPhysiqueContextExport::GetVertexInterface() - Returns an IPhyExport pointer for the nth vertex.
• • Rigid non-blended vertices (assigned rigid to a single Node) will return an object that derives from IPhyRigidVertex.
  • Rigid Blended vertices (assigned rigid to more than one Node) will return an object that derives from IPhyBlendedRigidVertex.
  • All other vertices will return NULL, unless ConvertToRigid() has been called with the argument TRUE, in which case all vertices return either IPhyRigidVertex or IPhyBlendedRigidVertex.
• Rigid non-blended vertices (assigned rigid to a single Node) will return an object that derives from IPhyRigidVertex.
• Rigid Blended vertices (assigned rigid to more than one Node) will return an object that derives from IPhyBlendedRigidVertex.
• All other vertices will return NULL, unless ConvertToRigid() has been called with the argument TRUE, in which case all vertices return either IPhyRigidVertex or IPhyBlendedRigidVertex.
• IPhysiqueContextExport::ReleaseVertexInterface() - You must call this method to free the vertex interface from memory.

Vertex Export Interface

The vertex export interface is an instance of IPhyVertexExport and can is retrieved by calling IPhyContextExport::GetVertexInterface(). This is the base class for all vertex export interface classes.

• IPhyVertexExport::GetVertexType() - Returns an integer representing the defined vertex type for the a vertex interface. We suggest using dynamic_cast<T*> and comparing against NULL instead to query the interface type.

Rigid Vertex Export Interface

The interface IPhyRigidVertex derives from IPhyVertexExport and is the base class for all non-blended rigid vertex assignments.

• IPhyRigidVertex::GetNode() - Returns an INode pointer for the node (bone/link) to which the vertex is assigned.
• IPhyRigidVertex::GetOffsetVector() - Returns the coordinates of the vertex in the local coordinates of the associated INode.

Blended Rigid Vertex Export Interface

The interface IPhyBlendedRigidVertex derives from IPhyVertexExport and is the base class for all blended rigid vertex assignments.

• IPhyBlendedRigidVertex::GetNumberNodes() - Returns the number of nodes to which this vertices is assigned with blending.
• IPhyBlendedRigidVertex::GetNode() - Returns an INode pointer for the nth node (bone/link) to which the vertex is assigned with blending.
• IPhyBlendedRigidVertex::GetOffsetVector() - Returns the coordinates of the vertex in the local coordinates of the nth INode pointer.
• IPhyBlendedRigidVertex::GetWeight() - Returns the weight of the vertex assigned to the nth INode pointer.
