如何保持形状ILCube [英] How to keep shape in ILCube

问题描述

我想绘制一些3D曲面与ILNumerics。我注意到，ILCube不保持表面的形状，如果我旋转它，那是因为它试图以适应ILPanel多维数据集。如果我使用ILCamera，但是，它将保持形状，但在它周围有没有立方体。下面是一个例子，

I want to plot some 3d surfaces with ILNumerics. I noticed that ILCube does not keep the shape of surface if I rotate it and it is because it tries to fit the cube in the ILPanel. If I use ILCamera, however, it will keep the shape but there is no cube around it. Here is an example,

private void ilPanel1_Load(object sender, EventArgs e)
{
    var scene = new ILScene();
    ILArray<float> A = ILSpecialData.torus(0.75f, 0.25f);
    var sf = new ILSurface(A);
    var pc = new ILPlotCube();
    pc.TwoDMode = false;
    scene.Add(pc);
    pc.Add(sf);
    sf.Colormap = Colormaps.Jet;
    var cb = new ILColorbar();
    cb.Location = new PointF(1, .1f);
    sf.Children.Add(cb);
    ilPanel1.Scene = scene;
}

和的结果是

和ILCamera

private void ilPanel1_Load(object sender, EventArgs e)
{
    var scene = new ILScene();
    ILArray<float> A = ILSpecialData.torus(0.75f, 0.25f);
    var sf = new ILSurface(A);
    var cam = scene.Camera;
    cam.Add(sf);
    sf.Colormap = Colormaps.Jet;
    var cb = new ILColorbar();
    cb.Location = new PointF(1, .1f);
    sf.Children.Add(cb);
    ilPanel1.Scene = scene;
}

和的结果是

有没有什么办法让ILCube保持表面的形状？或添加一个立方体周围表面到ILCamera？谢谢你。

Is there any way to make the ILCube to keep the shape of the surface? Or add a cube around the surface to the ILCamera? Thanks.

推荐答案

剧情立方体目前不支持等于轴的纵横比。但它是相当简单的添加这个自己。

Plot cubes currently do not support equal axis aspect ratios. But it is fairly simple to add this yourself.

有关你的榜样，情节立方体（圆环）的含量沿Z轴拉长，圆环体，因为延伸的Z比X或Y方向更小。因此，积魔方选择拉伸内容，以提供更好的细节。

For your example, the content of the plot cube (torus) is stretched along the Z axis, because the extend of the torus along Z is smaller than in X or Y direction. Hence, the plot cube chooses to stretch the content to give better details.

为了显示不变形的圆环，确保情节立方体的轴范围等于在所有方向上：

In order to show the torus without distortion, make sure the axis range of the plot cube equals in all directions:

pc.Limits.Set(new Vector3(-1,-1,-1), new Vector3(1,1,1));

缺点：你将不得不调整限值（添加/删除/修改，即数据）。每次设定的情节多维数据集的内容被修改。

Drawback: you will have to adjust the Limits setting everytime the content of the plot cube is modified (ie. data is added / removed / altered).
