how does getdepth function work in MarchingCube algorithm?

I am trying to understand Marching Cube Algorithm, so for I think I have understood how triangles are formed and how normals are calculated in each grid. I can see there is a linked list kind of structure that links each grid to another. But when I…

vtkMarchingCubes export nifti surfaces to wavefront OBJ

I want to run vtkMarchingCubes on a nifti label set. Regions of voxels, for which I want to produce surfaces all share the same value. I have two problems. First, I seem to be setting up the algorithm incorrectly because the resulting vtkPolyData…

Using noise to generate marching cube terrain?

I've succesfully made a marching cubes class in C# XNA and am using Lib noise to generate 3d perlin noise, but when I tried to generate terrain using the values of the perlin noise as the densities for my marching cubes it generates a large chunk of…

How to generate 3D mesh from CT Slices (.raw) using marching cubes algorithm in C#?

I am trying to generate 3D mesh (isosurface extraction) from CT slices(.raw file) using the marching cubes algorithm. The RAW data is 8 bits 512x512 px and 207 slices. So the input is CT Raw data and the output is a 3D mesh of the CT Object Can you…

Is there any fast algorith to find maximum outer contour of figure?

I have a labeled matrix obtained from scipy.measure.label. Now for each feature I need to obtain its outer contour. I tried cv2.findContours but contour it find not consist with labels. I think there should be a simple algorithm to do this, but…
