公共API和向后不兼容的更改

请参阅对公共API所做的任何更改的列表，如添加、重命名、删除或不推荐使用的成员，以及对Aspose.3D for .NET所做的任何非向后兼容的更改。如果您对列出的任何更改有疑问，请在Aspose.3D支持论坛。

将成员添加到Aspose.ThreeD.Deformers.Bone类

C#

 /// <summary>

/// Gets the weight for control point specified by index

/// </summary>

/// <param name="index">Control point's index</param>

/// <returns>the weight at specified index, or 0 if the index is invalid</returns>

public double GetWeight(int index)

/// <summary>

/// Sets the weight for control point specified by index

/// </summary>

/// <param name="index">Control point's index</param>

/// <param name="weight">New weight</param>

public void SetWeight(int index, double weight)

/// <summary>

/// Gets the count of weight, this is automatically extended by <see cref="SetWeight"/>

/// </summary>

int WeightCount{ get;}

/// <summary>

/// Gets or sets the transform matrix of the bone.

/// </summary>

Aspose.ThreeD.Utilities.Matrix4 BoneTransform{ get;set;}

将成员添加到Aspose.ThreeD.Deformers.MorphTargetChannel类

C#

 /// <summary>

/// Gets the weight for the specified target, if the target is not belongs to this channel, default value 0 is returned.

/// </summary>

/// <param name="target"></param>

/// <returns></returns>

public double GetWeight(Aspose.ThreeD.Entities.Geometry target)

/// <summary>

/// Sets the weight for the specified target, default value is 1, range should between 0~1

/// </summary>

/// <param name="target"></param>

/// <param name="weight"></param>

public void SetWeight(Aspose.ThreeD.Entities.Geometry target, double weight)

在类Aspose.ThreeD.Entities.NurbsCurve中添加成员

C#

 /// <summary>

/// Evaluate the nurbs curve

/// </summary>

/// <param name="steps">The evaluation frequency between two neighbor knots, default value is 20</param>

/// <returns>Points in the curve</returns>

public Aspose.ThreeD.Utilities.Vector4[]Evaluate(double delta)

/// <summary>

/// Evaluate the curve's point at specified position

/// </summary>

/// <param name="u">The position in the curve, between 0 and 1</param>

/// <returns></returns>

public Aspose.ThreeD.Utilities.Vector4 EvaluateAt(double u)

示例代码:

C#

 public static void Main(string[]args)

{

    NurbsCurve curve = new NurbsCurve();

    curve.ControlPoints.AddRange(new Vector4[]{

        new Vector4(-28.0118217468262, 53.0359077453613, 0, 1),

        new Vector4(8.95330429077148, 64.7735290527344, 0, 1),

        new Vector4(35.7778739929199, 42.424259185791, 0, 1),

        new Vector4(24.8725852966309, -4.86993026733398, 0, 1),

        new Vector4(-35.7778739929199, -34.192684173584, 0, 1),

        new Vector4(-18.6066780090332, -57.1458396911621, 0, 1),

        new Vector4(17.733715057373, -64.7735290527344, 0, 1)

    });

    curve.KnotVectors.AddRange(new double[]{0, 0, 0, 0, 0.25, 0.5, 0.75, 1, 1, 1, 1});

    foreach (var pt in curve.Evaluate())

    {

        Console.WriteLine(pt);

    }

}

将成员添加到Aspose.ThreeD.Entities.NurbsCurve类

C#

 /// <summary>

/// Convert the nurbs surface to the mesh

/// </summary>

/// <returns></returns>

public Aspose.ThreeD.Entities.Mesh ToMesh()

将成员添加到Aspose.ThreeD.Transform类

一些FBX文件包含一个非零的节点前/后旋转值，这两个属性将它们暴露给用户，并允许您操作它们。

C#

 /// <summary>

/// Gets or sets the pre-rotation represented in degree

/// </summary>

Aspose.ThreeD.Utilities.Vector3 PreRotation{ get;set;}

/// <summary>

/// Gets or sets the post-rotation represented in degree

/// </summary>

Aspose.ThreeD.Utilities.Vector3 PostRotation{ get;set;}

将成员添加到Aspose.ThreeD.Utilities.MathUtils类

C#

 /// <summary>

/// Convert a number from radian to degree

/// </summary>

/// <param name="x">The x component in radian value.</param>

/// <param name="y">The y component in radian value.</param>

/// <param name="z">The z component in radian value.</param>

/// <returns>The degree value.</returns>

public static Aspose.ThreeD.Utilities.Vector3 ToDegree(double x, double y, double z)

/// <summary>

/// Convert a vector from degree to radian

/// </summary>

/// <param name="x">The x component in degree value.</param>

/// <param name="y">The y component in degree value.</param>

/// <param name="z">The z component in degree value.</param>

/// <returns>The radian value.</returns>

public static Aspose.ThreeD.Utilities.Vector3 ToRadian(double x, double y, double z)

旧代码示例:

C#

 MathUtils.ToDegree(new Vector3(x, y, z));

MathUtils.ToRadian(new Vector3(x, y, z));

现在可以简化为:

C#

 MathUtils.ToDegree(x, y, z);

MathUtils.ToRadian(x, y, z);

成员在Aspose.ThreeD.Formats.GLTFSaveOptions中更新

旧定义

 System.Func<Aspose.ThreeD.Shading.Material, Aspose.ThreeD.Shading.Material> MaterialConverter{ get;set;}

新定义

 //New definition

Aspose.ThreeD.Formats.MaterialConverter MaterialConverter{ get;set;}

MaterialConverter的定义与旧函数具有相同的签名<Material, Material>:

C#

 /// <summary>

/// Custom converter to convert the geometry's original material to GLTF's PBR material.

/// </summary>

/// <param name="mat">Old material instance</param>

/// <returns>New material instance</returns>

public delegate Material MaterialConverter(Material mat);

添加新类Aspose.ThreeD.Entities.VertexElementVector4

此类是VertexElementNormal，VertexElementVertexColor，VertexElementBinormal，VertexElementTangent，VertexElementUV和VertexElementSpecular的新基类。它不会影响用户的侧代码。

成员被修改为Aspose.ThreeD.Entities.NurbsCurve类

旧定义

 System.Collections.Generic.List<double> KnotVectors{ get;}

新定义

 IArrayList<double> KnotVectors{ get;}

成员被修改为Aspose.ThreeD.Entities.Nurbdirection类

旧定义

 System.Collections.Generic.List<double> KnotVectors{ get;}

新定义

 IArrayList<double> KnotVectors{ get;}
