Change Details

This is a rough proposed outline of tasks to work on for the code quest (based on discussion between @campbellbarton & @sergey). * Blender 2.8 ** Interface *** COW display evaluated data, edit original. ** Depsgraph *** Building depsgraph from an arbitrary ID block. **** This can be used for efficient calculation of motion paths. **** Viewport motionblur **** Sequencer prefetch rendering frames (in threads). *** Best get input from Sergey. *** Performance (investigate) *** COW ** Modifiers *** Remove derived-mesh ** Layers *** UI (design) *** Check Performance For larger scenes current layer system likely has poor performance given the way linked lists are used. It would be good to measure what the difference w/ 2.7x is, if this is something to address, set as TODO or if we can leave as-is. *** Moving between layers *** Best get input from Dalai More work is needed to finish this off, not sure how much. *** How do set-scenes work w/ layer visibility? ** Asset Manager? Make it part of code-quest??? *** Needs discussion w/ Bastien (just focus on this until it's done?). Suggest to finalize design w/ UI guys, can fix technical issues later. ** Drawing Code Basics *** Workbench Engine *** Add back some missing options? - xray, wireframe. *** OpenGL selection has remaining bugs Maybe small, need investigaion. *** Sculpting Bugs *** Performance (investigate) *** Clipped output (alt-b) ** Drawing API's *** Resolved fixed buffer size for immediate mode. *** GPU - cleanup naming, remove deprecaed API's. *** Move to GPU (use BLI_threads) Use blender's code style. *** Wayland (ok after code-quest!) ** Overrides *** UI Design *** See: Bastien, Dalai for UI, more development, testing. Depends on COW. *** Access from Python (for later). ** Workspace *** Topbar design (keep redo panel where it is) *** Fix crashes in scene linking. *** Finalize object mode design & stabilize. *** Finalize bare minimum for release, possible extras. ** Operators *** Port to COW *** Undo system restructure and make linear (optional) *** Multi-object edit-mode (optional) ** Tools *** 101 Project, design is needed. ** Manipulators *** UI Design Reevaluate existing design. check if any changes are needed. *** More work to do, polish, usability, continued development. *** Confirm current API design is OK to go ahead with. We could re-evaluate a handful of minor things. *** Use to replace notifiers over the rest of Blender. ** Python API *** COW support At least exporters should export evaluated data> *** Various minor changes T47811 (best handle after the code-quest). *** Update all add-ons (again, after code-quest) ** Versioning *** Tests loading complex production files. Ensure basics are supported & no crashes. *** Check if we can make 2.8 files load in 2.7x On basic level, all layers visible. ** Refactor *** Split some files to help w/ merge conflicts Check files over ~3000 LOC, also use common sense! *** CMake: remove BLENDER_SORTED_LIBS P522 ** Sequencer *** Scene strips w/ COW, layers.. drawing engines? *** Make breaking changes **** Transform especially has very strange behavior **** Remove grading in linear space option. *** FUN: Camera navigation in sequencer (optional). (pixel based options making output at different sizes confusing) while we dont have time for a large project, we could improve things we know are bad-by-design. *** Prefetch frames (optional, nice to have, fits nice w/ COW) ** Physics & Particles *** Bring back 2.7x level of support Make the modules a blackbox, keep existing files working-ish. ** Remove deprecaed features *** Blender Internal! *** Texture Nodes (redo or remove - currently) *** Armature Sketch *** BGE Player *** Mesh Legacy Format (pre BMesh). *** Remove tessface **** Cycles: use looptri (detect quads if needed). **** Remove from RNA: Python IO needs updating **** Particles: We need operator to re-distribute to tris (can't do in readfile). **** BVH utils uses still. *** Remove non-triple buffer drawing. *** Screen Capture *** Frame Server *** AVI-RAW/JPEG *** Remove Current BGE Implementation in 2.8 Replace with interaction mode at later date. * After Code-Quest Topics ** Nodes *** Move cycles away from hard-coded C definitions.
