//Create a transform that translates (1, 0, 0) then rotates alone the y axis pi radian.

var m  = Matrix4.RotateFromEuler(0, Math.PI, 0) * Matrix4.Translate(1, 0, 0);

添加新类Aspose.ThreeD.实用程序.ComposeOrder和Aspose.ThreeD.实用程序.TransformBuilder

变换构建器通过一系列操作简化了变换矩阵的创建。

 //use prepend order so the calculation is performed from left to right:

var m = (new TransformBuilder(ComposeOrder.Prepend))

    //Change the (x, y, z) into (x + 1, y, z)

    .Translate(1, 0, 0)

    //Rotate alone with the Y axis with 180deg will change the (x, y, z) into (-x, y, -z)

    .RotateEulerDegree(0, 180, 0)

    //Scale by 2 will change the (x, y, z) into (2x, 2y, 2z)

    .Scale(2)

    //change the (x, y, z) into (z, y, x)

    .Rearrange(Axis.ZAxis, Axis.YAxis, Axis.XAxis)

    .Matrix;



//Apply this matrix on a (0, 0, 0) vector, then we get the right result (0, 0, -2)

var t = m * Vector3.Origin;

成员更新为Aspose.ThreeD.Formats

此更改引入了一个新的类Aspose.ThreeD.Formats.PlyFormat，它允许您对单个网格而不是整个场景进行编码:

 public static readonly Aspose.ThreeD.FileFormat PLY;

//Changed to

public static readonly Aspose.ThreeD.Formats.PlyFormat PLY;



// sample code

// Create a cylinder object and save it to ply file

FileFormat.PLY.EncodeMesh(new Cylinder(), "cylinder.ply");

添加新类Aspose.ThreeD.Formats.PlySaveOptions

Ply格式没有官方标准，不同的应用程序可能对其顶点格式有不同的定义，此类允许您定义Ply格式的详细信息。例如，纹理坐标组件的默认组件名称是 ‘u’ 和 ‘v’，但是某些应用程序使用 ’s’ 和 ’t’，然后您可以使用此类更改名称:

 //Save as binary PLY format, the default value is ASCII

PlySaveOptions opt = new PlySaveOptions(FileContentType.Binary);

//change the components to 's' and 't'

opt.TextureCoordinateComponents.Item1 = "s";

opt.TextureCoordinateComponents.Item2 = "t";

//save the mesh

FileFormat.PLY.EncodeMesh(new Cylinder(), "cylinder.ply", opt);
