2.8 topics #1783

i might not be available to do any of this. |
|
why? |
|
external pressures :/ |
|
what does mean |
|
not sure from what I understand
( not a massive issue... but if we don't follow the new convention it will be lifeless ) Not sure if or how Node subclasses will be treated. Lukily we already prefix most of those anyway :) |
|
we can definitely already migrate menus/operators and panel to be consistent with the regex Blender will use: pattern = `[A-Z][A-Z0-9_]*_MT_[A-Za-z0-9_]+` |
|
If Sverchok does not work with Blender 2.8, I will stick with 2.79 for a
while.
|
|
2.8 doesn't draw the nodeview properly on my crappy Lenovo laptop. I've been told to wait about 6 months before taking 2.8 serious enough to work on GL code. |
|
if we keep up to date with 2.79 nightly builder bot builds the final step-over to 2.8 will be less of a jump. |
|
External pressure :) Like a comet set on direct path with Earth ? :) |
comets. the universe's answer to ignorance :) |
|
Bl_idname. What to do? Not clear to me. Where to read? |
|
The link at the top @nortikin is all the information we've been given. But .. for example # SvMoveSocketOpExp(Operator, MonadOpCommon)
SvMoveSocketOpExp -> SV_OT_MoveSocketOpExp |
|
I am not sure if we need to manually pass bl_idname = "node.sverchok_move_socket_exp"it might already default to something else if we don't. # bl_idname = "ops.SV_OT_MoveSocketOpExp"will need to experiment. |
|
Oops, I didn't know github would create a notice here if I linked this issue from my repository, sorry. Since I'm here already: |
|
Changing in user interface: |
|
I am very curious on how SV can just work in 2.8, maybe there will be some
changes.

ImportError: cannot import name 'glBegin' |
|
BGL go crazy |
|
Some more news about Blender 2.8 UI: https://developer.blender.org/T55386 |
|
New node editor is coming:
|
|
2.8 is already alpha. |
|
Sverchok can be forced to "work" on 2.8. But without all nodes what use BGL, and nodetree updates only on frame change. Also no way to link new objects to scene. Some icons missing. Here testing branch: https://github.com/nortikin/sverchok/commits/Blender-2.8-testing |
|
I heard on |
|
Yes, I received the same from them. It is okay... ish... The only thing I am worrying about is that there might be too small gap between "python api stabilization" and "blender release" dates for us to update sverchok. |
|
i think it's perfectly acceptable for a non trivial add-on (like Sverchok) to take some time to update. Once the scripting interface is ready for the bgl replacement. i'm not going to spend time doing this, i wish others didn't either. ( i already did tests early on : https://github.com/nortikin/sverchok/tree/b28_test ) |
|
https://developer.blender.org/T56644 |
|
https://devtalk.blender.org/t/everything-nodes-with-sverchok/2029 also they say it is better place. |
|
bgl now exists again in 2.8 nightly builds, but glBegin and _End are no longer supported ImportError: cannot import name 'glBegin' from 'bgl' (unknown location)seems like we must now construct proper VBO. i'll dig into this. :) |
|
looks like fun :) |
|
https://wiki.blender.org/wiki/Reference/Release_Notes/2.80/Python_API/Addons and Also not register_module, but register_class |
|
|
|
|
well, if we acess own class, will it looks like: sverchok.trees['__name__'].datasteps[3]=np.array([.....])? |
|
not sure.. but am tempted to start the port very soon. (and no backward compatibility... time for a fresh start? ) keep it very basic at the start.. only very few nodes. |

i'm starting the 2.8 port now. i need distraction or something :) |
|
lol.. where is nodeview in 2.8 now ? :) |
|
that is a question... How AN deal? |

it's already partially working, it was a lot of work... adding the viewers back today (new versions of existing viewer/objects nodes) |
|
|
|
current status is here in this pullrequest: #2299 |
|
|
|
Can be useful. |

closing this because i dont want to have todolists in two places for the same project |
This issue hopes to collect major Blender Python API changes that may or may not affect sverchok.
see: https://wiki.blender.org/index.php/Dev:2.8/Source/Python/UpdatingScripts
bpy.utils.register_modulefunction, this doesn't affect us much..or maybe at all.bl_idnameof operators/menus/headers/panels and uiLists.update=updateNodeto traverse the graph.bgldrawing ( stethoscope, vdmk2, indexviewer ) are all impacted.bpy.types(small task- done!)bpy.types(big task- done!)Regisering classes
A suggestion on that page gives: ( i like this.. we can use this a lot..can even use our own version of this for pre 2.8 sverchok ..)
this will work for most node files, i'm not immediately aware that any nodes register scene variables directly in
register(but there might be one or two)bl_idname
...
BGL
a few
bglfunctions that we use are now dropped frombgl. I'm not sure how large the impact on the drawing code is. Good opportunity to write a new Viewer node.see : https://gamedev.stackexchange.com/questions/34108/opengl-vbo-or-glbegin-glend
