All Known Subinterfaces:

ILcdOpenFlightNode

All Known Implementing Classes:

TLcdOpenFlightBSPNode, TLcdOpenFlightDegreeOfFreedomNode, TLcdOpenFlightExternalReferenceNode, TLcdOpenFlightFaceNode, TLcdOpenFlightGeometryNode, TLcdOpenFlightGroupNode, TLcdOpenFlightHeaderNode, TLcdOpenFlightInstanceDefinitionNode, TLcdOpenFlightInstanceReferenceNode, TLcdOpenFlightLevelOfDetailNode, TLcdOpenFlightNode, TLcdOpenFlightObjectNode, TLcdOpenFlightSubFaceNode, TLcdOpenFlightSwitchNode, TLcdOpenFlightTransformableNode, TLcdOpenFlightVertexNode

public interface ILcd3DMeshNode

Describes a node in a hierarchical tree of 3D meshes. Each node can contain geometry in the form of one or more ILcd3DMesh objects, Each node can furthermore have a transformation matrix that applies to itself and its children. This interface can be used to model scene graph style data formats such as Collada or OpenFlight.

Since:

2015.1

Method Summary

Modifier and Type	Method and Description
List<? extends ILcd3DMeshNode>	getChildren() Returns this node's children, or an empty list if the node is a leaf node.
List<? extends ILcd3DMesh>	getMeshes() Returns the geometry contained in this node, in the form of 3D meshes, or an empty list if this node does not contain any data.
double[]	getTransformation() Returns a transformation matrix that applies to this node and its children.

Method Detail

getMeshes

List<? extends ILcd3DMesh> getMeshes()

Returns the geometry contained in this node, in the form of 3D meshes, or an empty list if this node does not contain any data.

Returns:

a list of 3D meshes, possibly empty but never null

getTransformation

double[] getTransformation()

Returns a transformation matrix that applies to this node and its children. The matrix should be 4x4 elements in column-major order. This is the same convention used by OpenGL functions such as glLoadMatrix(). null can be returned and represents the identity matrix.

Returns:

a 4x4 column-major transformation matrix, possibly null

getChildren

List<? extends ILcd3DMeshNode> getChildren()

Returns this node's children, or an empty list if the node is a leaf node.

Returns:

a list of children, possibly empty but never null
