Porting Tracker

[ibgreen]

Basic Deck/Layer/View integration (no rendering)

Ensure we have the API to drive layer diffing

Environment (2 days)

• Setup CMakefile
• Setup test framework: https://github.com/google/googletest
• Setup Travis CI
• Setup cpplint
• Setup xcode project

math library (1 day)

• initial math library for 4x4 matrices, vector3 etc. (write our own but can change later).
• Rectangle

Viewport (10 days) - @isaacbrodsky

• Port viewport.js (Viewport base class)
• Port web-mercator-viewport.js (WebMercatorViewport)
• Port web-mercator-utils.js
• Port viewport-uniforms.js
• Port test cases

Viewport/View integration (5 days) @isaacbrodsky / @ibgreen

• Port view.js
• Port view-state.js
• Port view-manager.js
• Implement View.makeViewport
• Port test cases

JSON Support (10 days)

• Integrate jsoncpp (Json::Value)
• Implement basic Component/Props system to allow props to be set from JSON.
• Decide on how to handle properties (dynamic vs strongly typed).

Layer base class (5 days)

• Implement layer class and property diffing
• Test cases for layer
• Test cases for property diffing

Deck class (5 days)

• Scaffold Deck class.
• Scaffold LayerManager class.
• Implement Deck properties and property diffing.
• Integrate layers, push layers through property diffing.

Arrow Integration (15 days)

• Implement jsoncpp (Json::Value) to Arrow (Table) converter for inline tables.
• Change Layer.data prop to Arrow Table
• Make accessors to work on rows
• If not, create Row abstraction class for table? (Layer accessors need to work on "rows")
• Investigate if Arrow C++ Table has iteration facilities.
• Create test cases that show CSV files being parsed into Arrow Tables
• Create test cases that show JSON files being parsed into Arrow Tables
• Integrate arrow vcpkg module

C++ Math Expression Parser

• Select expression parser module
• Add expression support to JSON converter (@@= strings)
• Compatibility of expression syntax across JS/C++ (OK to change JS...)

Loaders

• Add support for loading data over the network

Rendering

• Dawn integration
• Investigate memory leaks

Out of scope

Interactivity (P2)

controllers (2 days)
