ChengduLittleA is back! This short passage is for LANPR's
(probable) GSOC2019 project.
Development logs are here!链2 Work in progress!
What is this
LANPR is a 3D NPR feature line rendering engine developed by ChengduLittleA, it is aimed to replace legacy Freestyle. If you are new to LANPR project, why not read the introduction链3 first? (in Chinese) Last year, ChengduLittleA has already made everything in LANPR work with Blender, and it can take on some basic production on NPR renderings. Learn more about LANPR's GSOC2018链4.
- Achieve LANPR to GPencil/SVG format (Co-operation with Darkdefender guy). If GPencil converting is OK then we can implement SVG export from generic GPencil data. Variable width information should be stored in Inkscape identifiable format (such as brush strokes). Layers should also be included.
- Make a more intuitive UI. Current UI is too developer-oriented, not really good for art producto work with. At least one present will be included, making LANPR ready to render in default style the moment you switch to the engine. Some parameters should be combined with Blender's internal ones to avoid strange value settings.
- Optimize composition of line and solid rendering results. Currently, render results are composed by a composition scene who directly links to the original one, there should be a better way. Composition method that Freestyle uses might bring some additional problems to LANPR's rendering process, additional considerations requires.
- Fix bugs in triangle-clipping algorithms.
- Camera shift should be supported. After supporting this function, LANPR can then implement non-linear perspective feature. (Must finish the previous task)
- Optimize shaders for drawing lines, and try to provide some simple line patterns. It might be possible that LANPR inherent Freestyle's Line modifier stuff, we'll see on the go.
- CPU/GPU calculation modes are fast enough now, so LANPR plans to deprecate image space edge detection mode (Snake mode). For circumstances who needs such function, one can easily done this in composition nodes.
Concerns on the plans for this GSoC:
- School schedule. I'm doing school project review this semester. So I will have to spend less time on GSoC (compared with last year). Under this condition, I choose to implement the most crucial and most required functions only.
- More focus on getting into master branch. Relatively lighter tasks would enable more time to be spent on code review.
This is not the final list, If you are users who use/will use LANPR for production, please contact ChengduLittleA to state your opinion. Thank you!
- Fast and stable output of LANPR will become the fundation of many production fields like Manga/Animations.
- LANPR produce accurate result for any model, which means it can also be used to display complex structures.
- The intuitive UI should lower the bar for the ones who wants to learn LANPR. The design should be simpler than Freestyle for the users.
Planned time schedule
|Development for||Estimated time||Remarks|
|GPencil/SVG exporting||1 Week|
|UI and composition workflow||1 Week|
|Clipping bug fixes and camera shift capability||1-2 Weeks|
|Shader optimization||1 Week|
|Code review and modifications||For the rest of the time|
|Freestyle line modifier adapatation||2 Weeks||Need investigation|
