The optimal algorithm can be configured to minimize the length of added edges or minimize the area of generated triangles. Click on the images below to get a full screen image of a reconstructed ear or full head from an MRI scan. Solids may also be reconstructed by extracting isosurfaces in the volume data. Several algorithms may be used for this. The algorithms implemented in Vaidak are Marching Cubes, Marching Tetrahedra, and the SpiderWeb algorithm.
Volume rendering allows the user to bypass the reconstruction and view the volume directly.
The rendering approach used in Vaidak is that of Ray Casting. A ray is cast from each pixel in the image space through the volume being rendered. Data values in the volume map to color and opacity values given in a colormap.
