''September 28th, 2016''

The meeting happened informally between Ton Roosendaal and Dalai Felinto at the Blender Institute on top of the Viewport design posted on code.blender.org [1]. It is summed up here with its core points, to help refine the presented design towards an implementation and data flux document.

= Introduction =

The post on code.blender.org was aimed at the user experience, work structure and deliverables. It was built with a few assumptions that need extra clarification when we bring the original Blender 2.8 data design diagram [2] to the table:

[[Image:Blender 2.8 data levels.jpg]]

= Layers not plates =

It is fine to keep the concept of plates as the atomic components of the visualization pipeline. From the data evaluation and usability point of view, however, layers or passes may be a more clear concept. Part of the motivation for non-linear elements (i.e., plates) was to allow for individual data fetching per viewport. So it would be up to the viewport to determine if we would get animated fluids, particles, …

If we think on layers, we can expand Julian Eisel’s Layer Manager project [3] and build on it. This gives a direction for UI and usability as well.

= Layers belong to the scene data =

We will support per-viewport layer overwrite, and de/activation. But to determine which data (objects, …) we may use has to be set in a scene level. To illustrate this, think of a viewport that shows objects A and B, and another viewport that shows objects C and D. Which objects would appear in the Dopesheet? How about the outliner? And the node editor?

= UI/UX - user interface and usability =

The original idea was to keep user interface out of the development cycle until the Workflow sprint in late November. However it will be more powerful to explore a route (on top of the layer management project) to present and discuss at the sprint. We then adapt our functionalities after the sprint if needs be, or use it as a start point to tackle other areas of Blender.

= Documentation =
A diagram expanding the original Blender 2.8 data design will help keeping everyone on the same page. The idea is to put together a diagram with the viewport drawing dataflow and see how long it lives. An updated version of the posted document should be kept in wiki.blender.org for future reference and later updates.

= Next steps =

A new editor will be created to host the new drawing code. The idea is to port over any code that may be re-used, while getting one of the MVPs started. As soon as possible the gsoc layer code will be merged to start controlling the layers and exploring the new UI.
