API Änderungen

Aktualisiert den Objekt typ von Dictionary<String, Object> auf object in der Klasse Aspose.ThreeD.Entities.VertexElementUserData:

        /// <summary>
        /// The user data attached in this element
        /// </summary>
        public object Data { get; set; }

Wenn der alte Code mehrere Daten in VertexElementUserDataanhängt, sollten Sie jetzt mehrere VertexElementUserData verwenden.

Mit diesen Änderungen API können wir die Konvertierung von VertexElementUserData 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.ControlPoints.AddRange(controlPoints);
// Create polygons to mesh
// Front face (Z+)
mesh.CreatePolygon(new int[]{ 0, 1, 2, 3 });
// Right side (X+)
mesh.CreatePolygon(new int[]{ 1, 5, 6, 2 });
// Back face (Z-)
mesh.CreatePolygon(new int[]{ 5, 4, 7, 6 });
// Left side (X-)
mesh.CreatePolygon(new int[]{ 4, 0, 3, 7 });
// Bottom face (Y-)
mesh.CreatePolygon(new int[]{ 0, 4, 5, 1 });
// Top face (Y+)
mesh.CreatePolygon(new int[]{ 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.UserData, MappingMode.Polygon, ReferenceMode.Direct); ;
//The name of the UserData will be used as the field's name
userData.Name = "__FACE_ID";
userData.Data = new double[]{
        0,1,2,3,4,5
};
var triMesh = TriMesh.FromMesh(mesh);
Console.WriteLine("TriMesh:");
foreach(var vtx in triMesh)
{
        Console.WriteLine(vtx);
}

Die Ausgabe ist:

TriMesh:
Position = (-5,0,5), __FACE_ID = 0
Position = (5,0,5), __FACE_ID = 0
Position = (5,10,5), __FACE_ID = 0
Position = (5,10,5), __FACE_ID = 0
Position = (-5,10,5), __FACE_ID = 0
Position = (5,0,5), __FACE_ID = 1
Position = (5,0,-5), __FACE_ID = 1
Position = (5,10,-5), __FACE_ID = 1
Position = (5,10,-5), __FACE_ID = 1
Position = (5,10,5), __FACE_ID = 1
Position = (5,0,-5), __FACE_ID = 2
Position = (-5,0,-5), __FACE_ID = 2
Position = (-5,10,-5), __FACE_ID = 2
Position = (-5,10,-5), __FACE_ID = 2
Position = (5,10,-5), __FACE_ID = 2
Position = (-5,0,-5), __FACE_ID = 3
Position = (-5,0,5), __FACE_ID = 3
Position = (-5,10,5), __FACE_ID = 3
Position = (-5,10,5), __FACE_ID = 3

Position = (-5,0,-5), __FACE_ID = 4
Position = (5,0,-5), __FACE_ID = 4
Position = (5,0,-5), __FACE_ID = 4
Position = (5,0,5), __FACE_ID = 4
Position = (-5,10,5), __FACE_ID = 5
Position = (5,10,5), __FACE_ID = 5
Position = (5,10,-5), __FACE_ID = 5
Position = (5,10,-5), __FACE_ID = 5
Position = (-5,10,-5), __FACE_ID = 5
