3D Part Preview added to Parts Tracker

[Lasse Deleuran]

I think what is wanted is the colors for all the quads/tri/and subparts in the top level file to be randomized.

The following should cover that scenario:

Code:

// Half-Harlequin-mode:
      var acceptedColors = [1, 2, 4, 5, 13, 14, 19, 22, 25, 27, 69, 71, 72, 73, 74, 77, 288, 308, 484];
      THREE.LDRStep.prototype.addSubModel = function(subModel) {
        subModel.colorID = acceptedColors[Math.floor(Math.random() * acceptedColors.length)];
        this.subModels.push(subModel);
      }
      LDR.LDRGeometry.prototype.fromPartType = function(loader, pt) {
        loader.getMainModel().IS_MAIN_MODEL = true;
        let geometries = [];
        if(pt.steps.length === 0) {
          console.warn("No steps in " + pt.ID);
          return; // Empty - just make empty.
        }
        if(pt.IS_MAIN_MODEL) { // Harlequin the triangles and quads:
          pt.steps.forEach(step => {
            step.quads.forEach(quad => quad.colorID = acceptedColors[Math.floor(Math.random() * acceptedColors.length)]);
            step.triangles.forEach(triangle => triangle.colorID = acceptedColors[Math.floor(Math.random() * acceptedColors.length)]);
          });
        }

        pt.steps.forEach(step => {
            let g = new LDR.LDRGeometry();
            g.fromStep(loader, step);
            geometries.push(g);
        });

        this.replaceWith(LDR.mergeGeometries(geometries));
      }

It took me a bit longer to come up with this solution that I would like to admit!
