Public API and Backwards Incompatible Changes

See the list of any changes made to the public API such as added, renamed, removed or deprecated members as well as any non-backward compatible change made to Aspose.3D for .NET. If you have concerns about any change listed, please raise it on the Aspose.3D support forum.

API changes

The new features (Collada animation importing and exporting) in 18.4 do not introduce API changes.

The API changes in 18.4 are in two categories:

  1. For the consistence in Aspose.3D for Java API
  2. Removed obsoleted methods

SetData and SetIndices methods to Aspose.ThreeD.Entities.VertexElement class

Definition - C#

 /// <summary>

/// Load data

/// </summary>

/// <param name="data"></param>

public void SetData([] data);

/// <summary>

/// Load indices

/// </summary>

/// <param name="data"></param>

public void SetIndices(int[] data);

The new added methods are used to keep the API consistent between Aspose.3D for Java and Aspose.3D for .NET:

Code example - C#

 //Modified from

// UVs

Vector4[] uvs = new Vector4[]


    new Vector4( 0.0, 1.0,0.0, 1.0),

    new Vector4( 1.0, 0.0,0.0, 1.0),

    new Vector4( 0.0, 0.0,0.0, 1.0),

    new Vector4( 1.0, 1.0,0.0, 1.0)


// Indices of the uvs per each polygon

int[] uvsId = new int[]




// Call Common class create mesh using polygon builder method to set mesh instance 

Mesh mesh = Common.CreateMeshUsingPolygonBuilder();

// Create UVset

VertexElementUV elementUV = mesh.CreateElementUV(TextureMapping.Diffuse, MappingMode.PolygonVertex, ReferenceMode.IndexToDirect);

// Copy the data to the UV vertex element 

elementUV.SetData(uvs); //Equivalent to elementUV.Data.AddRange(uvs);

elementUV.SetIndices(uvsId); // Equivalent to elementUV.Indices.AddRange(uvsId);

Adds AddChildNode method to Aspose.ThreeD.Node class

Definition - C#

 /// <summary>

/// Add a child node to this node

/// </summary>

/// <param name="node">The child node to be attached</param>

public void AddChildNode(Aspose.ThreeD.Node node);

Code Example - C#

 Scene scene = new Scene();

Node newChild = new Node();

scene.RootNode.AddChildNode(newChild); // Equivalent to scene.RootNode.ChildNodes.Add(newChild);

Adds AddElement method to Aspose.ThreeD.Entities.Geometry class

Definition - C#

 /// <summary>

/// Adds an existing vertex element to current geometry

/// </summary>

/// <param name="element">The vertex element to add</param>

public void AddElement(Aspose.ThreeD.Entities.VertexElement element);

The new added methods are used to keep the API consistent between Aspose.3D for Java and Aspose.3D for .NET APIs

Code example - C#

 Mesh mesh = new Mesh();

VertexElement uv = new VertexElementUV();


Removes GetControlPointIndex from Aspose.ThreeD.Entities.NurbsSurface class

Definition - C#

 public int GetControlPointIndex(int u, int v)

Removes Load, Save and ToBitmap methods from Aspose.ThreeD.Render.ITextureUnit class

These methods were marked as obsoleted in version 17.8, the equivalent replacements can be found in the derived interfaces ITexture1D/ITexture2D/ITextureCubemap.

Definition - C#

 public void Load(Aspose.ThreeD.Render.TextureData bitmap)

public void Save(string path, System.Drawing.Imaging.ImageFormat format)

public void Save(System.Drawing.Bitmap bitmap)

public System.Drawing.Bitmap ToBitmap()
