API Änderungen

Aktualisiert den Objekt typ von Map<String, Object> auf Object in der Klasse com.aspose.threed.VertexElementUserData:

    /**
     * The user data attached in this element
     */
    public Object getData();
    
    /**
     * The user data attached in this element
     * @param value New value
     */
    public void setData(Object value);

Wenn alter Code mehrere Daten in Vertex Element UserData anhängt, sollten jetzt mehrere Vertex Element UserData verwendet werden.

Mit diesen Änderungen API können wir die Konvertierung von Vertex Element UserData in TriMesh unterstützen oder sogar in glTF exportiert werden:

Beispiel code:

//Manually define a cube
Vector4[]controlPoints = new Vector4[]{
        new Vector4(-5.0, 0.0, 5.0, 1.0),
        new Vector4(5.0, 0.0, 5.0, 1.0),
        new Vector4(5.0, 10.0, 5.0, 1.0),
        new Vector4(-5.0, 10.0, 5.0, 1.0),
        new Vector4(-5.0, 0.0, -5.0, 1.0),
        new Vector4(5.0, 0.0, -5.0, 1.0),
        new Vector4(5.0, 10.0, -5.0, 1.0),
        new Vector4(-5.0, 10.0, -5.0, 1.0)
};
// Initialize mesh object
Mesh mesh = new Mesh();
// Add control points to the mesh
mesh.getControlPoints().addAll(Arrays.asList(controlPoints));
// Create polygons to mesh
// Front face (Z+)
mesh.createPolygon(0, 1, 2, 3);
// Right side (X+)
mesh.createPolygon(1, 5, 6, 2 );
// Back face (Z-)
mesh.createPolygon(5, 4, 7, 6);
// Left side (X-)
mesh.createPolygon(4, 0, 3, 7);
// Bottom face (Y-)
mesh.createPolygon(0, 4, 5, 1);
// Top face (Y+)
mesh.createPolygon(3, 2, 6, 7 );

//create a user data to store face id for each face, this is done by specifying MappingMode to Polygon
var userData = (VertexElementUserData)mesh.createElement(VertexElementType.USER_DATA, MappingMode.POLYGON, ReferenceMode.DIRECT);
//The name of the UserData will be used as the field's name
userData.setName("__FACE_ID");
userData.setData(new double[]{
        0,1,2,3,4,5
});
var triMesh = TriMesh.fromMesh(mesh);
System.out.println("TriMesh:");
for(var vtx : triMesh)
{
        System.out.println(vtx);
}

Die Ausgabe ist:

TriMesh:
POSITION = (-5.0,0.0,5.0), __FACE_ID = 0.0
POSITION = (5.0,0.0,5.0), __FACE_ID = 0.0
POSITION = (5.0,10.0,5.0), __FACE_ID = 0.0
POSITION = (5.0,10.0,5.0), __FACE_ID = 0.0
POSITION = (-5.0,10.0,5.0), __FACE_ID = 0.0
POSITION = (5.0,0.0,5.0), __FACE_ID = 1.0
POSITION = (5.0,0.0,-5.0), __FACE_ID = 1.0
POSITION = (5.0,10.0,-5.0), __FACE_ID = 1.0
POSITION = (5.0,10.0,-5.0), __FACE_ID = 1.0
POSITION = (5.0,10.0,5.0), __FACE_ID = 1.0
POSITION = (5.0,0.0,-5.0), __FACE_ID = 2.0

POSITION = (-5.0,0.0,5.0), __FACE_ID = 4.0
POSITION = (-5.0,0.0,-5.0), __FACE_ID = 4.0
POSITION = (5.0,0.0,-5.0), __FACE_ID = 4.0
POSITION = (5.0,0.0,-5.0), __FACE_ID = 4.0
POSITION = (5.0,0.0,5.0), __FACE_ID = 4.0
POSITION = (-5.0,10.0,5.0), __FACE_ID = 5.0
POSITION = (5.0,10.0,5.0), __FACE_ID = 5.0
