Although it is not mandatory for the project of exam, it is interesting to try to create the texture or color per vertex, at least for the model obtained with David Scan. The operation, to be performed always with MeshLab is relatively simple: you have to “attack” HD photos on the object to exactly reproduce the realistic surface.\u00a0The color projection is a viable alternative to complex calculations of light scattering, it is necessary that you have the information on the chamber and the surface is completely covered. This operation is called “texture mapping” and allows, ultimately, to create an image (a png file, in our case) that describes perfectly the surface of the object.<\/p>\n
The coloring process is exactly the same for both acquisitions. The following is the description of work performed with David Scan, but what about NextEngine the speech is the same.<\/p>\n
Step 1 – Photo shoots<\/strong>
\nThe first step is to acquire high-quality picture of the item with the related information on the camera used. To achieve this I used a SLR camera EOS 60D, the generic features of the photos are as follows,\u00a0and below the photos (resized) used:<\/p>\n\n
