add size_space to pygfx.PointsMaterial scatter kwargs#689

FlynnOConnell

The size_space property of PointsMaterial controls which coordinate space to use for the sizing of each point. Default is screen, which using logical pixel values mapped to the screen. Zooming into a plot causes the thickness of circles to remain the same thickness. see here

This aims to allow the other options of CoordSpace Enum to be used instead (world, model, screen).

I'm not immediately seeing the need for a GraphicFeature here, but I could be wrong?

kushalkolar

All aspects of a graphic are managed by a GraphicFeature class and exposed to the user as properties: https://www.fastplotlib.org/ver/dev/developer_notes/graphics.html#graphic-properties

Lines also have a thickness_space parameter so this feature can actually be settable with a property of the PositionsGraphic base class.

kushalkolar

A good start!

This doesn't need to be specific to scatters, pygfx line material also uses a thickness_space property that takes the same args and does an analogous thing so this can be in the PositionsGraphic base class.

Will also need a simple test when you're done, see this for an outline:

fastplotlib/tests/test_positions_graphics.py

               fig = fpl.Figure() 
        
               kwargs = dict() 
        
               for kwarg in ["thickness"]: 
        
                   if locals()[kwarg] is not None: 
        
                       # add to dict of arguments that will be passed 
        
                       kwargs[kwarg] = locals()[kwarg]

               graphic = fig[0, 0].add_line(data=data, **kwargs) 
        
               if thickness is None: 
        
                   thickness = 2.0  # default thickness 
        
               assert isinstance(graphic._thickness, Thickness) 
        
               assert graphic.thickness == thickness 
        
               assert graphic.world_object.material.thickness == thickness 
        
               if thickness == 0.5: 
        
                   assert isinstance(graphic.world_object.material, pygfx.LineThinMaterial) 
        
               else:

Eye test looks like everything checks out. will work on a test case next

kushalkolar

Since you've added/changed the API you will need to regenerate the API docs:

in docs/source:

delete the api dir

with the env activated, run:

python generate_api.py

add and commit docs/api

kushalkolar

black is still unhappy, just do black fastplotlib/

only black format the fastplotlib source dir, not the examples or tests etc.

FlynnOConnell

plz tell black to stop complaining

FlynnOConnell

@kushalkolar I don't even have a guess for why the docs failed

Run SamKirkland/FTP-Deploy-Action@v4.3.5 Error: Error: Input required and not supplied: server

kushalkolar

I think it's trying to access the credentials which are repo secrets and it won't since you're on a fork, we'll figure out later how to make docs upload from forks. Anyways the docs built without issues so that's fine and everything else LGTM.
