Cross mode integration

Open discussion about the cross mode future

Cross mode is excellent at drawing complex graphics

Cross mode is not Asciio

It uses Asciio as an environment to draw graphics.

We have discussed some points already but I think we should list them here and write a requirement about how Cross mode would work if it was integrated.

Difference with Asciio

• can't move objects as if they were connected, because they aren't
• connects anywhere not just at connection points
  • Asciio can connect anywhere but elements need to be setup accordingly
• fillers are extra elements
• fillers, I think, stops the user from selecting the arrow end to move it

Separation from Asciio

The graphics drawing mode, what we call Cross-mode today needs to be separated even more

• bindings need to go to a different file
• the application that starts it shouldn't be called Asciio, like the TUI is called Tasciio.
• code needs to be moved into another directory

Integration it into Asciio

What I believe the cross mode to be is a graphic overlay. a way to change how things look like without changing the underlying structure or adding anything.

in Asciio there should be very little difference between these renderings of the same objects.

The only differences are:

• Asciio is aware of the rendering overlay
• the elements have an extra attribute to tell the overlay they want to be drawn differently or not

New Asciio rendering pipeline

• is element part of an overlay
• is the rendering cache valid
• use cache or re-render
  • call overlay to get new strips
• display the element

optimization opportunities

• Asciio only calls the elements that are part of the overlay, overlay code can be simplified
• Asciio can keep a 2/3D map, the overlay doesn't need to compute it
  • 2D map is sparse
• Asciio can cache data generated from the overlay if necessary, simplifies the overlay

@nkh

Are you already integrating cross mode?

Or do you need to wait until I fix these little bugs you mentioned?

[nkh]

@qindapao I have merged it but it's not working, give me 30 min maxand if I can't find what it is I will push the merged code for you to look at.

I like the diff, a lot of code is gone.

@nkh 👌okay

@qindapao

I have created a separate ticket, let talk there until it's fixed.
