Visualize voxel data in viewport

Post by jgascon » Thu May 10, 2012 2:02 pm

Hi,

I am working in a medical image project and we would like to use Blender as visualizer and editor of volumetric data.

After watching the video http://www.youtube.com/watch?v=7PSPiUrrXsg I am aware that Blender is capable of loading and rendering volumetric models.

Moreover I have seen that Blender is capable of displaying smoke in the viewport in real time, but, is it also capable of displaying voxel and volumetric data in the viewport?

Would it be very difficult to add this functionality?

Thank you very much!

Jorge

Another nice vid showing how to RENDER voxel data:

but displaying it in viewport seems not possible, unless you use vertices. Mesh verts can be used as density input for a point density texture. Verts show in viewport as black/orange dots.
I'm sitting, waiting, wishing, building Blender in superstition...

Hi! thank you for the video, but I think that I have found a solution, I do not know if it could be very difficult to implement or not.


Thanks to Kai Kostack, I have found a way to render voxels in real time, using the BGE. Thanks to Martinsh:

But... Could it be possible to have a visualization mode in blender in order to display things with GLSL shaders enabled? You know: Wireframe mode, solid mode, ... , shaders mode...

What do you think about this feature?

Hello. I would appreciate i you could tell me how did you used blender game engine to visualice the voxel data.
I'm doing some ullustrations for my phd in neuroscience and i've got a lot of photos taken by a transmission electron microscope. My aim is to build a reconstruction taking the voxel data as an accurate reference. So i need to visualice the voxel on the air. Not only after rendering.
Thanks
