I'm using jit.gl.gridshape / capsule, with one of the dimension hugely stretched (use the scale attribute for that)

The result is quite nice (seems like infinite lines in my 3D universe)

I'd like to calculate the distance between the cam and those structures.

 helped a bit to learn again some formulas.

Basically, the faster calculation is the distance between a segment & a point.

To define the segment (my hugely stretched object), I need coordinates of extremities' points..

Is there a way to draw gridshape using those coordinates, natively?

Preferring to ask before to design a factory to do that :)

maybe you want to draw your shape using jit.gl.path instead of gridshape?

that way you can specify the two endpoints.

the distances calculation will be easier like that and visually, I'll work with this primitive and I have so much to learn about texture/capture/slab stuff... to make them glowing, distorting light or I don't know what :p

Hi Robert,
just tested.
it sounds PERFECT for me.

Calculate a distance between the cam and big gridshape segment ?
