如何在 ILNumerics 中进行手动着色？

Question

我用 ILNumerics 制作了一些盒子（图片右侧）。正如您在左侧看到的那样，每个框都有不同的属性。

实际上，我想按照我的定义为框着色。颜色本身取决于“Delta Rho”，它的最大值 = 1，最小值 = -1。我也想显示彩条。如何让它发生？有人知道吗？

顺便说一句，这是我的代码：

private void createBlockBody(BlockBody BlockBody, ILScene scene, ILPlotCube plotCube)
    {
        ILArray<double> A = ILMath.rand(1, 20) * 4 + ILMath.vec(1, 20);
        plotCube.Add(new ILTriangles("tri")
        {
            Positions = new float[,] { 
            // front side
            {(float) BlockBody.UpperLeftPoint.X,(float) BlockBody.UpperLeftPoint.Y, (float) BlockBody.UpperLeftPoint.Z}, 
            {(float) BlockBody.UpperLeftPoint.X + (float) BlockBody.dx, (float) BlockBody.UpperLeftPoint.Y + (float) BlockBody.dy, (float) BlockBody.UpperLeftPoint.Z},
            {(float) BlockBody.UpperLeftPoint.X + (float) BlockBody.dx, (float) BlockBody.UpperLeftPoint.Y, (float) BlockBody.UpperLeftPoint.Z},

            {(float) BlockBody.UpperLeftPoint.X,(float) BlockBody.UpperLeftPoint.Y, (float) BlockBody.UpperLeftPoint.Z},

找到答案了！

plotCube.Add(box);
var colormap = new ILColormap(Colormaps.Jet);
Vector4 key1 = colormap.Map((float)BlockBody.Rho, new Tuple<float, float>(-1, 1));
var test = key1.ToColor();
box.Color = test;
