How to modify tick's range in Image3D
Suppose we have an array of color data
colorArray = ParallelTable[With[{v = RandomReal[]},
Append[List @@ ColorData["LightTemperatureMap"][v], If[v >= .8, .5, 0]]
], {z, 0, .1, .005}, {y, 0, 1, .1}, {x, 0, 10, 2}];
And we use Image3D to visualize…

Limited Opacity Levels in Image3D?
I'm trying to render a simple spherical distribution where the opacity varies with radius using Image3D. Unfortunately, the outcome is not very appealing, with discrete colors showing up in the rendering:
You can see that not only are the colors…

Plotting Voxel in mathematica
I am developping a 3D reconstruction application. I recuperate the voxels coordinates (the coordinate of each voxel) of the object that I need to reconstruct. Each voxel have a dimensions like this 5cm*5cm*5cm. I need to reconstruct this volume. I…

How to remove white margins of a rendered image of an Image3D object?
This question is related to this. In the case of Graphics3D, there is an option for Method->{"ShrinkWrap"->True}, however, there is no such option for Image3D.
Consider an example as
head = ExampleData[{"TestImage3D", "CThead"}];
and a sample…

Add points to 3D image
I have 2D image data set for 3D image.
Since my data is very large, in this question, I use sample data.
testdata = Import["ExampleData/CTengine.tiff", "Image3D"];
sl = Image3DSlices[testdata];
(The the structure of my own data is same as…

Import 3D image
Is there a way of importing 3D images to Mathematica that will not be unicoloured? I would like to use a colourful 3D image in a discrete mapping so that one can visually see the transformation and relocation of the pixels.
Thanks in advance!

How is the sample 3D image of Knee is created?
The sample 3D image of knee in Mathematica is the MRI of Markus van Almsick(https://www.youtube.com/watch?v=s1ot5MltxM8&spfreload=1).
The corresponding image dimension is {128, 128, 128}.
However, normally MRI consists of 20-25 2D slices. If this is…
