Viewport Project

This document aims to describe the 2.8 Viewport Project, and to help facilitate discussion and communication on the project. Only high-level details (goals, tasks, etc) should be in this document. For lower-level implementation details, please use this page. It should also be noted, that this project is a workflow and user experienced focused project and is not focused on performance and under-the-hood improvements to Blender's viewport drawing. For such improvements, look at the OpenGL project. Weekly progress reports can be found on this page.

Objective

Improve the workflow and user experience of Blender's 3D viewport including improvements to previewing for rendering and exporting.

Roadmap

Discussion Items

The following are items to be discussed for eventual inclusion into the project.

Roadmap!
Physically-based rendering following Unreal Engine 4's model
Move selecting and picking outside of OpenGL (default bvhs everywhere)
- Note: OpenSubiv needs special attention since it doesn't support ray tracing, could be solved by adding patches to BVH which can be rasterized on CPU
Better rendering of selection outline / indication in the viewport
Workflow modes (sculpters, modelers, animators, game designers, etc)
- Ways to config this and switch efficiently
Good material previewing of cycles nodes
Blender as a shader editor
- Be able to use those shaders for previewing assets before export
OpenGL 3.2 Core minimum
Look into OpenGL 4 + AZDO (try to be compatible with Vulkan as well) for hardware that supports this
Allow viewport to be reused by game engine
Support viewport renders from command line/in headless mode

Goals

TODO: Formalize some of the discussion items into concrete goals
