Methods

FindBone(Int32)

Finds the bone that is using a given node index.

Declaration
[Unmanaged]
public int FindBone(int nodeIndex)
Parameters
System.Int32 nodeIndex

The index of the node.
Returns
System.Int32

The index of the bone or -1 if not found.

FindBone(String)

Finds the bone with the given name.

Declaration
[Unmanaged]
public int FindBone(string name)
Parameters
System.String name

The name of the node used by the bone.
Returns
System.Int32

The index of the bone or -1 if not found.

FindNode(String)

Finds the node with the given name.

Declaration
[Unmanaged]
public int FindNode(string name)
Parameters
System.String name

The name of the node.
Returns
System.Int32

The index of the node or -1 if not found.

GetBox(Matrix, Int32)

Gets the model bounding box in custom matrix world space (rig pose transformed by matrix, not animated).

Declaration
[Unmanaged]
public BoundingBox GetBox(Matrix world, int lodIndex = 0)
Parameters
Matrix world

The transformation matrix.
System.Int32 lodIndex

The Level Of Detail index.
Returns
BoundingBox

The bounding box.

GetBox(Int32)

Gets the model bounding box in local space (rig pose, not animated).

Declaration
[Unmanaged]
public BoundingBox GetBox(int lodIndex = 0)
Parameters
System.Int32 lodIndex

The Level Of Detail index.
Returns
BoundingBox

The bounding box.

SetupLODs(Int32[])

Setups the model LODs collection including meshes creation.

Declaration
[Unmanaged]
public bool SetupLODs(int[] meshesCountPerLod)
Parameters
System.Int32[] meshesCountPerLod

The meshes count per lod array (amount of meshes per LOD).
Returns
System.Boolean

True if failed, otherwise false.

SetupSkeleton(SkeletonNode[])

Setups the skinned model skeleton. Uses the same nodes layout for skeleton bones and calculates the offset matrix by auto.

Declaration
[Unmanaged]
public bool SetupSkeleton(SkeletonNode[] nodes)
Parameters
SkeletonNode[] nodes

The nodes hierarchy. The first node must be a root one (with parent index equal -1).
Returns
System.Boolean

True if failed, otherwise false.

SetupSkeleton(SkeletonNode[], SkeletonBone[], Boolean)

Setups the skinned model skeleton.

Declaration
[Unmanaged]
public bool SetupSkeleton(SkeletonNode[] nodes, SkeletonBone[] bones, bool autoCalculateOffsetMatrix)
Parameters
SkeletonNode[] nodes

The nodes hierarchy. The first node must be a root one (with parent index equal -1).
SkeletonBone[] bones

The bones hierarchy.
System.Boolean autoCalculateOffsetMatrix

If true then the OffsetMatrix for each bone will be auto-calculated by the engine, otherwise the provided values will be used.
Returns
System.Boolean

True if failed, otherwise false.
