I wonder know the dataset of this paper(includes the classify between buildingmass, roof or stairs and the pointNet training dataset) maybe something unpublished, it's very pleasure to share them with me. : ) have fun

Regarding dataset: You can search for "procedural modeling" techniques, especially referring to this paper [1]. This is a rather traditional computer graphics algorithm. Through adjusting L-system grammars, you can automatically generate a large number of 3D building models very fast. Once you get the hierarchy/mesh of the buildings, you can easily extract any desired information (including edges and corners). Certainly, you can also jitter the edges to approximately simulate the human-drawn strokes.

For your information, I attached some buildings that were generated by my implemented L-system algorithm, which is indeed a powerful approach to rapidly generate numerous 3D models. Thus, I strongly recommend you try the algorithm in the paper [1] as well if you would like to do some building-related stuff.

But.... I am afraid that you may have to re-implement it from scratch, because unfortunately, many CG (graphics) researches are not open-source. They typically involve heavy workloads and huge programming efforts, thereby making them valuable properties to the owners.

If you need further information, you can leave your WeChat ID 微信 here (I guess you're chinese too? or at least study in CN).

I will contact you very soon after you get back to me. (I will delete the message with your Wechat ID once it's done).

Wish you a happy new year.
