Volume Render

Volume Render GUI with mouse change able color and alpha maps

Description

This is a Fast Volume Render application, using OpenGL surfaces.

Color and alpha maps can be changed on the fly by dragging and creating markers in a histogram with the mouse.

Note:
There is a bug / memory leakage in the Matlab function colormap incombination with OpenGL. If there is a solution please leave a message ...

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7.5 (R2007b)

Matlab has been traditionaly VERY slow in 3d visualization (see isosurfaces)
However, I have seen minor speed improvements in r2008a
To full exploit OpenGL is a real need and this contribution goes in that direction

getrangefromclass () function missing. Could you post please?

Thanks,

Petr

Petr,
getrangefromclass() returns [0 1] or if integer:
range=double([intmin(class) intmax(class)]);

It is good cool staff, however, when I used for a new data, it did not work for me, and I can not figure out :(

I guess it will be nice if you can provide one more example and show how to adjust inputs for your cool package, thanks,

Very Nice. Been looking for something like this.

works very good with my real data but it doesn't work with my synthetic data. Where can I find any explanation (the concept) of this code?

[Dirk-Jan Kroon]

That only your real data works and not your synthetic is probably caused by the data-type of your volume and value-range of your data. Maybe you have to convert the data first to uint8 with a range of 0...255 before you can use the viewer.
