##Superconductor ###Parallel Web Programming for Massive Visualizations

Public Backends

• Sequential JavaScript layout w/ canvas rendering
• WebCL layout w/ WebGL rendering
• Stale: CUDA, OpenCL, C++, ASMJS, Qt

Other Known

• Graphistry: Web workers layout w/ WebGL rendering
• Berkeley: Rust

###Compiling from source

• Install nodejs, java + ant, swi-pl
• In "superconductorjs", run "npm install"
• In "superconductorjs", run "make all"
• In "compiler", run "ant" . You may need to fix up "local.properties" (template in "local.properties.mac")

###Test

Run "./runTestWebServer.sh" from the main folder to launch a local test server

Unit tests (pixel/zoom tests report false negatives)

• Sequential (any browser): http://localhost:8888/examples/boxes/index.html?webworkerLayout=false&ignoreCL=true&ignoreGL=true
• WebCL (WebCL-enabled browser): http://localhost:8888/examples/boxes/index.html?webworkerLayout=false&ignoreCL=false&ignoreGL=false

Demos

• Treemap (WebCL): http://localhost:8888/examples/treemap/index.html?webworkerLayout=false&ignoreCL=false&ignoreGL=false
• 3D Line Graph (WebCL): http://localhost:8888/examples/linegraph-3d/

WebCL

The GPU version requires a browser with WebCL bindings.

Tested

OS X 10.8.5 and 10.9.2 Safari (Samsung): https://github.com/wolfviking0/webcl-webkit

Tip: Make sure WebGL is enabled from the developer menu. Tip: Try the n-body example that comes with WebKit
