![]() In areas of your model where loop consistency is desired and there are no branching areas, use Through guides, longitudinally and laterally, starting and stopping the guide line outside of the mesh area. Fingers should be given guides that start and the tip and continue beyond the wrist, when possible (the longer the better). In these cases, the guide should be drawn as a continuous line starting before the shoulder and extending beyond the wrist and well into the hand area. where an arm meets a shoulder or an arm joins a hand). The best practice, when dealing with organic shapes that have appendages (arms, legs, fingers), is to start and stop the guide lines before and after connecting joints, where a thinner piece of geometry meets a thicker piece (i.e. However, adding guides which do not reach far enough can result in this unpleasant twisting of edge loops and polygon rings. Retopology Using Instant Meshes Old-style quadrangulationįlow Guides: When no guides are placed by the user, AUTOPO usually produces good polygon flow throughout the resulting mesh, with no unwanted twisting. For further information about Instant Meshes, please visit the following website of IGL and their more detailed demonstration of it. Instant Meshes: This video is a brief overview of the Integration of the “Instant Meshes” Auto-Retopo engine into 3DCoat, as an option to using 3DCoat's default Auto-Retopo engine. Since our algorithm avoids any global optimization, and its key steps scale linearly with input size, we are able to process extremely large meshes and point clouds, with sizes exceeding several hundred million elements. #3D COAT AUTORETOPO FULL#Our full pipeline executes instantly (less than a second) on meshes with hundreds of thousands of faces, enabling new types of interactive workflows. The method is simple to implement and parallelize, and it can process a variety of input surface representations, such as point clouds, range scans and triangle meshes. Our algorithm produces meshes with high isotropy while naturally aligning and snapping edges to sharp features. We present a novel approach to remesh a surface into an isotropic triangular or quad-dominant mesh using a unified local smoothing operator that optimizes both the edge orientations and vertex positions in the output mesh. If you do not like the automatic result, you can always go to the Retopo Room to manually adjust the mesh to suit your needs.Īlso, when using this function, 3DCoat will automatically create a new sub-object in the Paint tab for each object If the object is not fully symmetrical, the program will keep symmetry only whenever possible. It is a good idea to enable symmetry planes to force symmetry during the process of creating automatic topology - (assuming you want a symmetrical object). There are a few things to note about the AUTOPO tools. UV seams and Maps are created automatically. AUTOPO for Per Pixel: Runs AUTOPO and places the result in the Paint Room for painting with the “per-pixel” method. AUTOPO with MV Paint: Runs AUTOPO and places the result in the Paint Room for painting with the “Micro-vertex” method. AUTOPO with Ptex: Runs the routine mentioned above and places the resulting mesh in the Paint Room for painting using Ptex. Now voxelize+hardsurface combination really has sense.ĪUTOPO: Create edge loops with AUTOPO: This routine creates surface topology based on your specifications given in the following dialogs, and places the resulting polygonal mesh in the Retopo Room. You need to turn on “Hardsurface” mode to enable this sort of detecting. It creates “feature strokes” automatically in this case. Now it works correctly with lowpoly meshes as well (even with irregular triangulation with long triangles).Īlso it may detect sharp edges even over relatively “soft” voxelized objects. ![]()
