Setting the point of origin of a 3D volume in a 3D window

Post by Grégory Operto »

Hi everybody,

I am creating small AimsData volumes that I'd like to display around a specific vertex of a mesh. I used to create big volumes full of zeros except in the area covered by my small volume of interest, which gives exactly what I want. But it is consumes time and memory, in particular when there are several time steps in my volume. I was then wondering if there wouldn't be a way to set the reference location of any volume in a 3D window, either at run-time or while writing the .ima file, so that I can shift my small volume along the mesh.

Thanks for any help :)

Not all volume formats accepts an origin. But if you know the translation between your mesh and your volume, you can use a transformation to register them.
