[Bug] The example of contourrendering cannot display contours on 3D

[IrvingLu]

Describe the Bug

The example of contourrendering cannot display contours on 3D saw that the code for this example removed the 3D display, and I don't understand why it was removed. When I try to display the outline, I will report the following error：

undefined is not iterable (cannot read property Symbol(Symbol.iterator)) TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator)) at Function.from () at updateContourSets (http://localhost:3000/tutorial.js:136362:41) at handleContourSegmentation (http://localhost:3000/tutorial.js:136332:3) at Object.render (http://localhost:3000/tutorial.js:136241:105) at http://localhost:3000/tutorial.js:137342:44 at Array.map () at SegmentationDisplayTool.renderSegmentation (http://localhost:3000/tutorial.js:137327:75) at SegmentationRenderingEngine._triggerRender (http://localhost:3000/tutorial.js:156046:37) at http://localhost:3000/tutorial.js:155922:14

It was not removed really you still can render contour in 3D. if it does not work it is a bug, but for 2D rendering of contours you have to use the new svg based contour rendering

Thank you for your reply. It is indeed not working. I have updated it to the latest version and now it is reporting the following error：

Can we take a step back? Please explain your use case. Why do you want to render contours in the 3D volume rendering?
