The STL file contained more than 700000 triangles, and, due to noise and lack of accuracy in the process, it exhibited a large number of disconnected components. The STL file was then processed at the Institute of Industrial Automation using software tools developed in-house. After removing the noise, we were left with 4 components. It was vital that these components retained their spatial relationship after manufacturing, and, therefore, the model had to be modified by introducing interconnecting structures. Bars were also needed to enhance the rigidity of the physical model.
Chromosomes are extremely complex.
Several visualization techniques are used to understand their structure, including electron microscopic tomography, hidden line removal, stereo projections, and animations. Physical models, though, may become an indispensible tool for researches in the field.
