Speak briefly, PixiJS + BJS VS orthographic camera.
What am I trying to achieve is drawing a contour on a ground and let the user create an extrusion from it.
So, if you’re familiar with such tools, you may see that drawing lines usually done with 2D scene.
I think, best user expirience will be with PixiJS, but and I also believe it is gonna be hell for me
maybe you can share something on jsfiddle?
