3D文档管理控件Aspose.3D v19.6发布上线！加强气缸的创建！

Aspose.3D for .NET是一个功能丰富的游戏软件和计算机辅助设计（CAD）API，用于处理3D文档格式，无需任何3D建模和渲染软件依赖。支持Discreet3DS、WavefrontOBJ、FBX（ASCII，二进制）、STL（ASCII，二进制）、Universal3D、Collada、glTF、GLB、PLY、DirectX、Google Draco文件格式等。

Aspose.3D v19.6中的公共API更改

---

▲在类Aspose.ThreeD.Entities.Cylinder中添加了新的属性OffsetTop

////// Gets or sets the vertices transformation offset of the top side.
///public Vector3 OffsetTop
{
    get;
    set;
}

▲在类Aspose.ThreeD.Entities.Cylinder中添加新属性OffsetBottom

////// Gets or sets the vertices transformation offset of the bottom side.
///public Vector3 OffsetBottom
{
    get;
    set;
}

生成带有自定义偏移量的圆柱体的示例代码:

Scene scene = new Scene();
var fan = new Cylinder(2, 2, 10, 20, 1, false);
fan.OffsetTop = new Vector3(5, 3, 0);
scene.RootNode.CreateChildNode(fan).Transform.Translation = new Vector3(10, 0, 0);
var nonfan = new Cylinder(2, 2, 10, 20, 1, false);
scene.RootNode.CreateChildNode(nonfan);
scene.Save("test.obj", FileFormat.WavefrontOBJ);

左边的一个将OffsetTop设置为（5,3,0），很容易看到顶盖已经移动，整个躯干也受到影响。

▲在Aspose.ThreeD.Entities.Cylinder类中添加了新属性GenerateFanCylinder

////// Gets or sets whether to generate the fan-style cylinder when the ThetaLength is less than 2*PI, otherwise the model will not be cut.
///public bool GenerateFanCylinder
{
    get;set;
}

用于生成风扇式气缸和非风扇式气缸的示例代码：

Scene scene = new Scene();
var fan = new Cylinder(2, 2, 10, 20, 1, false);
fan.GenerateFanCylinder = true;
fan.ThetaLength = MathUtils.ToRadian(270);
scene.RootNode.CreateChildNode(fan).Transform.Translation = new Vector3(10, 0, 0);
var nonfan = new Cylinder(2, 2, 10, 20, 1, false);
nonfan.GenerateFanCylinder = false;
nonfan.ThetaLength = MathUtils.ToRadian(270);
scene.RootNode.CreateChildNode(nonfan);
scene.Save("test.obj", FileFormat.WavefrontOBJ);

左侧圆柱体具有GenerateFanCylinder = false，右侧圆柱体具有GenerateFanCylinder = true。

▲在类Aspose.ThreeD.Entities.Cylinder中添加了新的属性ShearTop

////// Gets or sets of the shear transform of the top side, vector stores the (x-axis, z-axis) shear value that measured in radian, default value is (0, 0)
///public Vector2 ShearTop
{
    get;
    set;
}

▲在类Aspose.ThreeD.Entities.Cylinder中添加了新的属性ShearBottom

////// Gets or sets of the shear transform of the bottom side, vector stores the (x-axis, z-axis) shear value that measured in radian, default value is (0, 0)
///public Vector2 ShearBottom
{
    get;
    set;
}

显示ShearBottom（ShearTop）用法的示例代码:

Scene scene = new Scene();
var cylinder1 = new Cylinder(2, 2, 10, 20, 1, false);
cylinder1.ShearBottom = new Vector2(0, 0.83);// shear 47.5deg in xy plane(z-axis)
scene.RootNode.CreateChildNode(cylinder1).Transform.Translation = new Vector3(10, 0, 0);
var cylinder2 = new Cylinder(2, 2, 10, 20, 1, false);
scene.RootNode.CreateChildNode(cylinder2);
scene.Save("test.obj", FileFormat.WavefrontOBJ);

左边的圆柱体为剪切底部到(0,0.83)，而右边的圆柱体为序数圆柱体。
