Auto Pathing

[VinskyStrauss]

Hi,
I'm currently trying to migrate a diagram from GoJS to the ngx-vflow. I think, It would be nice to have an automatic pathing algorithm for the edge between Node, because right now the edge will go through the nodes or cut each other. I found ngx-vflow really interesting. Thanks a lot for creating this library.

Hi! Do you have a live examples on GoJS or some other libraries? I would like to see how complex it would be to implement. It sounds like not a main priority, because I still need to add more basic things like a minimap

Hi, thanks for the reply. Here is a recording from the GoJS website as an Example.

Hi, there is this example as well from JointJS:

@VinskyStrauss thanks for example!

@jleroy-dev Thanks! Their implementation isn’t perfect, as there are still cases where lines collide with nodes, but it does look pretty cool.

Here's how I think this should be implemented:

• It likely shouldn’t be part of the core library. it could impact performance, increase the initial bundle size, and introduce potential bugs (such as lines occasionally colliding with nodes).
• I’ll add an API for drawing custom curves through a factory. The factory will receive flow data to calculate the curve accurately.
• Using this factory, I’ll experiment with an implementation as a gist or a separate npm package. This API will also allow others to create their own implementations—possibly even better ones, because I'm not good at math.
