Can a polygon mesh be converted to a B-spline surface?
In particular, if you set two adjacent control points to the same location in 3D space, you get a triangle. (c.f. Bézier triangle) Any polygon mesh can be subdivided into a triangle mesh through well-known methods. Once you have done that, you can just separately convert each triangle into a 2×2 b-spline surface.
How can I construct a 3D model from a polygon mesh?
I have a polygon mesh and I have done all the analysis to determine what surfaces I need to be able to construct a 3D model out of it. How can I, using Open CASCADE, construct a model using information such as where planes are located or the shape of a b-spline surface?
How to convert a quad mesh to a T-spline?
1. Insert your mesh (Insert/Insert Mesh) 2. Create a form 3. In the sculpt environment, go to the Utilities/Convert 4. Select the Convert Type of Quad Mesh to T-Splines Using this two-step workflow, you can convert any mesh as a T-spline model without creating a tessellated solid!
How to convert a quad mesh to a solid?
This article describes some best practices for first converting your polygon mesh to a quad mesh, and then converting it to a solid body for use in downstream operations. The main challenge to converting a mesh to a solid is avoiding production of a tessellated solid.
How to edit Rhino meshes in polygon format?
View and edit them with the various Rhino commands that apply to meshes (see Bonus > Mesh ). They can be exported to in polygon mesh formats like STL, DXF, 3DS, and OBJ. Meshes created during Save and Export (such as .stl) have the same mesh settings dialogs (“Detailed Controls”) as the other types.
What happens when you convert NURBS to polygon mesh?
The resulting polygonal object will continue to be the last valid (computed) polygonal surface that was visible. In some cases when converting multiple NURBS patches to a single polygonal mesh you may notice strange shading effects on the mesh. This is because of the normals.
Can a polygon mesh be subdivided into a triangle?
Any polygon mesh can be subdivided into a triangle mesh through well-known methods. Once you have done that, you can just separately convert each triangle into a 2×2 b-spline surface. Thanks for contributing an answer to Computer Science Stack Exchange! Please be sure to answer the question.
