art3mis Posted February 17, 2018 Share Posted February 17, 2018 (edited) Not sure if I should post this in Coding as the solution would be in VEX Have a simple physics simulation with a box Primitive, Solver and and Trail SOPs to create a 3d 'dashed line'. The problem is my 'dashes' aren't oriented so that they are tangential to the curve. Here is my initial VEX set up @v = {5,5,0}; v@gravity = {0,-0.1,0}; My .hip is also attached. Any VEX wizards able to help? Am familiar with Parallel Transport to compute normals on curved lines http://www.entagma.com/td-fundamentals-parallel-transport/#more-1145 but was hoping there was a simpler solution that allowed use of the Trail SOP. 3d_dash.hiplc Edited February 18, 2018 by art3mis Quote Link to comment Share on other sites More sharing options...
Deviner Posted February 20, 2018 Share Posted February 20, 2018 Hey Jim, I hope that's what you need. 3d_dash.hiplc Quote Link to comment Share on other sites More sharing options...
art3mis Posted February 20, 2018 Author Share Posted February 20, 2018 Thanks! I ended up using a Carve SOP with a copytopoints operation but I think this is a more elegant solution. Quote Link to comment Share on other sites More sharing options...
