Hi everybody, I was wondering if anyone have some ideas to import, read and use x/y/z positions of a vector file ?

what source material would that be that hosts your 3d vectors an .obj file then you can check the objLoader library.

I can provide models in dwg, obj, stl, 3ds, sat, so yes I will try the objloader library, thanks. But can I really read each points of the model and use them with the objloader library?

The first step for me would be doing this in 2D: importing a vector file (ai, dwg, dxf or whatever) and READING each point(x/y) of the drawing to re-use these informations to make some transformations on the drawing, or to make a calculator who can transform the geometrical informations (x/y) into motors informations (with arduino for example).

So my question is can I read the coordinates of a vector drawing already done with another software (autocad, solidworks, illustrator..)?

Answer is in sojamo's useful link.

Quote:
This library contains a class for loading/rendering a .OBJ file (OBJModel) and a class for accessing each vertex (Vertex) which can be primarily used to addressing vertexes in the model file and transform it.

Vertexes in OBJ formats is like this: (ASCII Format)
Code:

o object_name_example
v 525 200 -375
v 525 200 -475
v 625 200 -475
v 625 200 -375
v 525 200 -575
v 625 200 -575

The OBJLoader is working very well. If you only need paths or 2D shapes (no Curves, no Solids, no complex Textures) , OBJ format should be basic enough to help you to do this.
