comment How to modify tick's range in Image3D
Are you sure not a total reverse? My test shows that total reverse is the right to go. And I remember before your updating, your image3D is the same as OP, but now your image3D is clearer, this is weird, because I can't get such a clear image3D as yours

Sorry, I don't get it. What do you mean by "I don't know why mine is more clear, I get pretty much the same image from OP that I would get from my code"

I think we should Reverse[colorArray,{1,2,3}] before Image3D, to make the coordinate back to normal

@JasonB And also I just realize there is one more problem in coordinate. Check out tutorial/ImageProcessing, in the coordinate section. The coordinate should be upside down, because Image3D stack from top to bottom.

@JasonB Why now your image is much clear than OP's? I can not reproduce your image. What have you done?

@JasonB An update is enough, it is a small improvement : )

@JasonB Hi, Jason B. I found you actually don't need to create an empty Frame. Just embedded the Image3D in Show and apply the Ticks options in Show is a direct way.

comment weird behaviour of Listable fortran Librarylink function: different result each evaluation
@MarcoB But the .dll intel compiler generate gives correct answer when it is not Listable. So I think it is due to mma. mma's thread parallelization make a correct dll gives wrong answer

I notice in the human head example, the size is 100, that means if it were simply array of pixels, it should be 7MB, am I right?

I reconsidered and realized that I actually don't know the basic of rasterization, I am not familiar with image compression, wish you could correct me if I am wrong : )

comment How to make image3d smaller? Is `ImageResolution` useful?
Hi, Bill S. Thank you very much for your answer. But I think your approach maybe not what I want. Take the CT human head as an example, I think your method probably can not achieve that effect. I think the head should be generated in high detail first, and then efficiently rasterized and adjust resolution instead of directly deleting data point. I tried your method on my data, it seems not producing good looking quality.

@Louis Thank you very much. very useful link. But it is not dealing image3d. How to implement it to image3d?

@bbgodfrey Thank you bbgodfrey. That works. But the size reduction is not enough.
