Is there a way to draw a line with the mouse and have it be the center of a 3D tube?
I started by wondering if this would be possible using parametric equations with
Make Parametric Grid Mesh.
In my googling, I've found related "bent tube" things like sweeping a spline, extruding, torus knots, or making a tunnel in a game.
Regarding proper bends, I guess this means having some way to calculate the tangent from point to point? I can't quite imagine doing bends with parametric equations in
Make Parametric Grid Mesh, but this is where I am now. (I also want the radius to be dynamic for "blobby" or "liquid" like drawing, later).
It would be cool if
Make Tube (with its walls and caps) could somehow draw along a curve like this. Extrusion tools would also be cool (probably already a FR?). Also, I know @khenkel has the
Make Mesh with Values node, but that's a couple more degrees away from my current skill set.
