Hi all,
We realized the existing TriangleMesh API is too restrictive to support
additional vertex formats in the future, for examples, user specified
normal and multi-texture units. We will need to make at least 2 changes
to allow TriangleMesh be used for a range of vertex formats in the future:
1) The faces of TriangleMesh needs to be a new class that extends
ObservableIntegerArray. We can then add methods (in the future) to
provide views to the different components of the faces.
2) The following constants in TriangleMesh need to turn into instance
methods:
public static final int NUM_COMPONENTS_PER_POINT = 3;
public static final int NUM_COMPONENTS_PER_TEXCOORD = 2;
public static final int NUM_COMPONENTS_PER_FACE = 6;
Changes made to TriangleMesh:
- public static final int NUM_COMPONENTS_PER_POINT = 3;
- public static final int NUM_COMPONENTS_PER_TEXCOORD = 2;
- public static final int NUM_COMPONENTS_PER_FACE = 6;
- public final ObservableIntegerArray getFaces()
+ public final ObservableFaceArray getFaces()
Methods added to TriangleMesh:
/**
* Returns the number of elements that represents a Point.
*
* @return number of elements
*/
public final int getPointElementSize()
/**
* Returns the number of elements that represents a TexCoord.
*
* @return number of elements
*/
public final int getTexCoordElementSize()
/**
* Returns the number of elements that represents a Face.
*
* @return number of elements
*/
public final int getFaceElementSize()
New Class:
public interface ObservableFaceArray extends ObservableIntegerArray
Note: This class adds no new methods or fields in JavaFX 8.
Thanks,
