![]() In practice, it is often helpful to allow AUTOPO to determine its topology without assistance – just to see which areas need more guidance – (this applies to Flow Guides, too). You can paint these regions with freehand Brush Tools, or you can make more precise designations by using the “E” Panel tools. In models where you desire more polygonal density (for displacement purposes), 3DCoat allows you to designate these areas with a “mask”. But if you don’t care about edge loops and need quads to mess quickly, use it. Retopology Using Instant Meshes Old-style quadrangulation 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 for using 3DCoat’s default Auto-Retopo engine. Since our algorithm avoids global optimization, and its key steps scale linearly with input size, we can process extremely large meshes and point clouds, with sizes exceeding several hundred million elements. Our full pipeline executes instantly (in less than a second) on meshes with hundreds of thousands of faces, enabling new 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 layer in the VoxTree. 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. UV seams and Maps are created automatically.ĪUTOPO for Per Pixel: Runs AUTOPO and places the result in the Paint Room for painting with the “per-pixel” method. UV seams and Maps are created automatically.ĪUTOPO with MV Paint: Runs AUTOPO and places the result in the Paint Room for painting with the “Micro-vertex” method. ![]() Now voxelize+hardsurface combination has sense.ĪUTOPO: Create edge loops with AUTOPO: This routine creates surface topology based on your specifications in the following dialogs and places the resulting polygonal mesh in the Retopo Room.ĪUTOPO with Ptex: Runs the routine mentioned above and places the resulting mesh in the Paint Room for painting using Ptex. You need to turn on “Hardsurface” mode to enable this detection. It creates “feature strokes” automatically in this case. Now it works correctly with low-poly meshes (even with irregular triangulation with long triangles).Īlso, it may detect sharp edges even over relatively “soft” voxelized objects. Once mastered, these automatic tools will often produce completely usable models – ready for texturing and even animation – all with the minimum manual input and toil.Īuto-repo got an essential update. We continue to refine these routines to greatly reduce the number of man-hours needed to create 3D assets from start to finish – all within 3DCoat. We first brought you the most accurate and efficient automatic routines for adding usable Topology to Sculptural models – both organic and hard surfaced.
