Advanced Bonsai Workshop #2: Toolboxes and visual editor

The second part of a workshop series on the Bonsai programming language. This session covers the visual programming language concepts, editor and various abstractions included in the built-in packages.

1. Advanced Bonsai Workshop https://bitbucket.org/horizongir/bonsai January 18-21, 2016 Bonsai = Rx + VPL + Packages
2. Be Reactive Ask Questions
3. Workshop Programme 1. From databases to data streams 2. Bonsai toolboxes and visual editor 3. Observable combinators: An algebra for data streams 4. Representing discrete states with data streams
4. Bonsai toolboxes and visual editor January 19, 2016 Advanced Bonsai Workshop
5. Bonsai = Rx + VPL + Packages var stream = Camera().Select(Grayscale) .Sample(KeyDown()) .Do(SaveImage);
6. Bonsai is a visual programming language for manipulating reactive streams
7. Bonsai can be extended by installing new NuGet packages
8. The (growing) list of Bonsai packages • Dsp • Vision • Audio • Arduino • OSC (Open Sound Control) • Windows.Input • Scripting • Shaders • …
9. Replay: hot → cold
10. Publish: cold → hot
11. Bonsai branches publish by default
12. Types for image processing: IplImage 89 147 156 157 155 47 123 165 155 148 45 89 146 150 156 43 72 123 163 181 42 73 142 185 201 82 119 174 196 192 138 168 194 177 152 183 190 178 152 134
13. Types for multi-channel data: Mat 89 147 156 157 155 47 123 165 155 148 45 89 146 150 156 43 72 123 163 181 42 73 142 185 201 82 119 174 196 192 138 168 194 177 152 183 190 178 152 134
14. Creating property editors for online calibration
15. Visualizers can be stacked for context
16. Visualizers can be stacked for context
17. Visualizers can be stacked for context
18. Bonsai VPL = Expression Tree This means that things like this can make sense
19. Interfacing with the external world: Arduino
20. Externalized properties can be dynamically mutated online
21. Running Bonsai in batch processing mode 1. Externalized properties become command-line arguments 2. Batch mode terminates when ALL streams complete
22. Image synthesis: the GPU graphics pipeline Romain Vergne http://romain.vergne.free.fr/blog/
