Hi, I'm trying to decide the tool I'm going to use for my dissertation. And I want to learn people's opinion about OpenDX, VTK, IDL etc. Basically what I need a visualization package capable of volume rendering of high resolution CT data of bones. The second step involves getting quantitative results (bone volume, trabecular thickness) out of this data using thresholding techniques. Also polygon reduction of the 3d object and exporting into common 3d format are sometimes needed.
I used VTK for a while. It accepts and exports bunch of popular 3d data format. However I'm having a funny dll problem in Windows, and it takes forever to compile in RedHat 7 (because of library incompatibilities). I'm trying to learn OpenDX couple of weeks. Till now I couldnt succeed in making an isosurface. For those interested I provided an sample data set I'm using at http://susanville.eps.utexas.edu/~murat/dx The interslice spacing was 0.25 mm, and pixel spacing was 2mm on the original 512x512 data. It has been reduced to 100x100. Initially it used a RBG colormap, which I replace with AutoGrayScale function. I set the scalar value in isosurface for something around 120-130, a typical threshold I get from Scion Image. But it didnt change anything. I appreciate any suggestion/help you can offer. best, Murat
