Class RotationChunk

java.lang.Object
  com.microcrowd.loader.java3d.max3ds.chunks.Chunk
      com.microcrowd.loader.java3d.max3ds.chunks.RotationChunk

public class RotationChunk
extends Chunk

Extracts the rotation information from the 3ds file. Rotations occur about a pivot at a position within a local coordinate system. The rotation information is provided to the KeyFramerInfoChunk which then converts it to a global coordinate system and applies animation information. KeyFramerInfoChunk for more information about using animations from a 3ds file

Field Summary

static java.lang.String

ROTATION_TAG String that will be used as a data object in the transform that the RotationInterpolator will be a child of so it may be look up later.

Constructor Summary

RotationChunk()

Method Summary

Quat4f	getQuaternion(Vector3f axis, float angle) This converts a 3ds angle and axis to a quaternion rotation.
void	loadData(ChunkChopper chopper) Loads the quaternion for a rotation of a shape and notifies mesh info chunk.

Method Detail

loadData

public void loadData(ChunkChopper chopper)

Loads the quaternion for a rotation of a shape and notifies mesh info chunk.

Overrides:

loadData in class Chunk

Parameters:

chopper - the ChunkChopper containing the state of the parser.

getQuaternion

public Quat4f getQuaternion(Vector3f axis,
                            float angle)

This converts a 3ds angle and axis to a quaternion rotation. Successive rotations are relative to the first so each rotation must be made absolute by multiplying it with its predecessor
