  1. Hi, When using createTube(...) if the path consists of two Vertex3 objects that form a vertical line (same x and z coords), the mesh is not displayed. Here's a playground example: http://www.babylonjs-playground.com/#O8WDR#13. The first two meshes are not displayed, and the second two are. Thanks, Eric
  2. Hello, I've got the following "simple" code. This will be the most complex my model gets, probably, but currently it is not working. I receive the following error when I call BABYLON.Mesh.CreateTube, //... var tp = createArchPoints(10, 32); var tube = BABYLON.Mesh.CreateTube('my tube', tp, 2, 12, null, BABYLON.Mesh.CAP_ALL, scene); //... Which my arch points are created using the very helpful Quadratic Bezier calculation. var createArchPoints = function(dim, count) { var po = new BABYLON.Vector3(0,0,0); // origin var pc = new BABYLON.Vector3(0,0,dim); // control var pd = new BABYLON.Vector3(dim,0,dim); // destination var points = BABYLON.Curve3.CreateQuadraticBezier(po, pc, pd, count); return points; } I know the radius, will be constant; so I do not want a radius function. The points themselves, as far as I can tell, appear to be realistic, as expected. Is there something I need to do to dress the CreateQuadraticBezier result before passing them to CreateTube? My assumption is that one returned a Vector3[], which the other expects as a parameter, but I could be wrong, it's hard to tell sometimes with JavaScript being weakly typed. Any other calculations I need will be along the lines of rectangles in 3D space, even with a couple of transformations and translations, but these are more straightforward in my mind. To help with response, my level of js confidence is growing probably 4 out of 10; 3D about the same, my frame of reference are libraries like Helix Toolkit for WPF (C#) in which I've already done a similar model, just wanting to do something like that with Babylon; also loosely familiar with THREE, so probably same, 4 out of 10. That to say, I'm learning, but I can discuss halfway intelligently. Thank you... Regards, Michael Powell
  3. Hi guys! I have a tube mesh, created with an array of Vector3 points. I update this tube mesh adding new points to the path, but for some reason it's giving me errors like Uncaught TypeError: Cannot set property '0' of null Uncaught TypeError: Cannot set property 'x' of undefined http://babylonjs-playground.com/#85J9N#10 What am I doing wrong?
