3DMLoader for Three.js

Willem · September 4, 2020, 12:23pm

Hi Luis,

I’m trying to setup example files for our developer and find that not all curvetypes are supported.
Rhino file:
test_curves.3dm (42.3 KB)

imported in https://threejs.org/editor/

It looks like polycurves are not supported yet.

Is there some documentation or can you point me to the code where I can find what types of curves should already supported?

EDIT @Luis I fount this code , but I’m not sure if I an make sense of it.

github.com

mrdoob/three.js/blob/2327f4efd4b6713fd4820d50a26e5432c6ea9b69/examples/jsm/loaders/3DMLoader.js#L1054


				// console.log(`${property}: ${object[property]}`);

			}

		}

		return result;

	}

	function curveToPoints( curve, pointLimit ) {

		var pointCount = pointLimit;
		var rc = [];
		var ts = [];

		if ( curve instanceof rhino.LineCurve ) {

			return [ curve.pointAtStart, curve.pointAtEnd ];

		}

Further test makes it appear as if the curves are not rendered.
I exploded 1 curve as a test, and that does show up, bot I found that some curve object are selectable but not visible. Maybe due to the 100 point limit?

All in all very promising as it will eliminate a time bottleneck in our current coversion from Rhino to web!

Thanks
-Willem
