i am struggeling with the usage of the 3D Viewer Plugin. I have greyscale Images where the darkest regions display regions of high intensity. Now i would like to get an 3D Image via the 3D-Viewer-Plugin displaying those regions on white background. It works for me when i first invert all images so that i have white objects on black background (Picture A). Then the black background is transparent in the viewer but its not working vor white background for me (Picture B). Also when i try to use the threshold function of the 3D Viewer it does not change anything no matter what number im typing in.
Second question would be if it is possible to get an coordinate system in the viewer so that i know on which coordinates my objects are.
And before i open the next topic here is my third question: is it possible to interpolate between two pictures? The thing is that those pictures from which i want to construct the 3D Object are made by XRT and in reality there is 10 µm space between the pictures. One pixel has a size of 5.4 µm so i need the space between the voxels of two pictures with an interpolated voxel.
I’m thinking very hard about this the whole week but i cannot find an answer.
I really would apreciate help!
