You may also be able to create a slice with a clipping plane in the renderer or by using a custom shader in the GL viewport. The GL camera also has settings for near and far planes that are passed to the renderer.</p> <p>Everything in K-3D has points and these already have many types of "x,y,z space-distortion" type nodes, even function based ones that take user properties as input, so they are fully parametric!</p> <p>For splines we have nurbs curves and there is an SVG importer that can take drawings from Inkscape in a way that causes an update if you change your .svg file. </p> http://www.k-3d.org/forums/topic/tube-meshes-slicing-in-degrees-or-percents-and-splines#post-2759 Sun, 20 Dec 2009 23:18:45 +0000 Kronoes 2759@http://www.k-3d.org/forums/ <p>It would be nice to have a Tube Polygonal/Primitive. Also to have a slice Node Properties/plugin for all the Polygonal/Primitives. gmax has this, it's a good way to make cutaways of electric motors. Say you want to make a turbine and cut it in half without the cut being permanent. You can do this in gmax and after you are satisfied you make the mesh(Polygonal/Primitive) editable. You could do this with buildings and all kinds of things. When I design I usually never make the mesh(Polygonal/Primitive) editable, I save it under a different name, (exp: e for editable and u for uneditable. Twist and Rotation would be good Node Properties/plugin for Toruses as well as for the other Polygonal/Primitives. Splines simulate wires really well and thats in gmax too. You can use splines to create the thread of a screw bolt or nut, springs, and wires for electronics and for coils. </p>
