Q: Hi, I have a question regarding this:

Display input.mnc.gz object.obj
(R - Objects)
(W - Scan object to volume)
Let’s say my object is a simple sphere, but the co-ordinates have sub-voxel accuracy. If i do the above, then the resulting label that gets loaded onto the image will indeed be a sphere, but, for every vertex in my object, the entire corresponding voxel is colored on the volume. Is there a way to just paint the points/coordinates of the object onto the volume, or connect the points via a thin line, instead of just lighting up the entire voxel?

The best solution I have thus far is to resample my input volume to 0.1 mm isotropic voxels for example, and then the resulting label is much thinner, but this creates a huge file and is a waste of space and time.

A: I’m not sure if this helps, but you can try polygons_to_lines to get only lines. Nonetheless, a vertex will still be the size of a voxel (1mm) and the lines will be 1mm too. It would have been nice if Display had the ability to draw at the screen’s resolution (in pixels). Today’s graphics cards would support it. :-)
