排斥效果的问题

[ytr2010]

开发者大大您好，生成出的图的边会出现交叉、重叠在一起的问题，例如这样一幅图:

3 8
4 8
4 7
1 10
6 10
3 6
1 2
3 5
8 9
2 8
7 8
1 7
3 7
8 10
3 4
6 7
1 3
1 5
2 9
6 9

很难将他们平铺的分散一些使更加美观，可能是边长限制的问题，有时会出现互相吸引的问题（将边长调大会非常明显）

像一号点，如果想挪动，会导致其他点一起挪动，无法更加美观。

其次是手动调整功能可以添加一个把边弯曲的功能吗？

csacademy 的效果好像还行

对不起，我的中文很菜，所以我用英语回复吧。

I think adding curved edge physics (like in csacademy) is a bit tedious, because of the way multi-edges are implemented... It's not impossible of course, but I'd rather find some simpler alternative.

After some experimenting, I think two things could help:

1. Support even longer edge lengths
2. Increase the node repulsions (specifically between nodes that aren't directly connected by an edge)

@satorimarch If you have any opinions you can mention too haha.

[satorimarch]

The current physics system cannot prevent edges from overlapping, regardless of parameters. It's especially obvious in tree mode. Bigger node repulsions doesn't mean resolving edge overlapping. However, I understand that implementing node-edge collision detection and bending edges dynamicly, like CS Academy, is challenging... and I agree your approach can relieve this issue.

Thanks for ur feedback! You may try out the dev branch to see if the new physics configurations (under "Appearance") feels natural to use. In the long run when I find the time, I might implement the node-edge collision detection to make it better.

Sorry, I forgot about this issue until someone reminded me. It looks good, so just merge the dev branch into main.

[anAcc22]

Don't worry bout it! I'll merge to main.
