![]() I think it’s very unlikely, given how good native SubD is, that Clayoo will continue to exist for much longer. With all of that said, Rhino SubD is still much, much better than Clayoo already for a number of reasons, the most dramatic being that Clayoo doesn’t play well with rhino osnaps, which is incredibly frustrating. This fits with “build in box mode” thinking) I prefer Clayoo’s implementation of lofting and extruding degree 1 curves (Clayoo’s subdivisions across option splits each segment individually.WYSIWYG preview, with sliders for adjusting the number of segments across and along when executing many SubD creation commands.Knife (there are easy but slow workarounds for this in Rhino right now, though).The features Clayoo has that Rhino SubD lacks that I think are the most important to add are: Array symmetry and multi-symmetry seem like they’re jobs better suited to grasshopper, but I guess there’s no reason for them not to be available in Rhino. Mesh wires are drawn in viewports for preview, and the dialog box stays on screen for more adjustments.There are a few missing functions that I hope will be high on the agenda during early R8 WIP development. The default value is 4 and the accepted range is 1 to 5. A smaller level results in faster meshing, less accurate meshes, and lower polygon count. This setting controls the adaptive or absolute subdivision level of the meshes converted from SubD objects. SubD meshing parameters for raytracing Level Step three and four can introduce new mesh vertices on edges. Only the second step can introduce new mesh vertices in the interior of the meshed surface. In all further steps, new triangular faces can be introduced in the mesh. In the first step, all mesh faces are quadrangles. Meshing error is typically measured as the distance between the mesh edges midpoints and the surface. This step does nothing if “ Jagged seams” is true or if the object being meshed is not a polysurface.Īll vertices generated by the meshing process are exactly on the surface. The fourth step combines coincident vertices along the joined surface edges to fill the gaps. This step does nothing if the object being meshed is a single untrimmed surface. The third step trims the mesh along the trimmed surface edges. This step does nothing if “ Refine mesh” is false. ![]() The second step refines the grid by subdividing some quadrangles of the initial grid until each quadrangle meets the meshing criteria. The spacing of this grid can vary along each direction, and is estimated to roughly meet the meshing criteria set in NURBS meshing parameters. If the surface is trimmed, the shrunk copy of the surface is used for this step. The first step creates a regular rectangular grid of vertices on the surface. Meshing a surface or polysurface in Rhino happens in up to four steps: How NURBS surfaces are converted to meshes? In the mesh refinement step, quadrangles are subdivided until the angle between surface normals is smaller than this value. Two vertices are neighbors if they are at the opposite ends of a single edge. In the initial grid step, this value controls the approximate maximum angle made by the surface normals at neighboring mesh vertices. ![]() If there is also an explicit non-zero Maximum distance, edge to surface value set in the dialog, then the mesher will use the smallest number for each surface. This value will be smaller as the Density setting gets closer to one, and for smaller surfaces. The formula is based on the size of the surface being meshed, and is used to generate a per-surface value for the Maximum distance, edge to surface parameter. Larger values result in a mesh with a higher polygon count. The default value is 0.5, and acceptable values are between 0 and 1. It uses a formula to control how close the polygon edges are to the original surface. ![]() Densityĭensity is the parameter controlled by the slider in the simple mesh controls dialog. All steps except the fourth are run independently for each face. Many of these parameters are shared between the first and second steps.
