##Description

Wizi provides a interface for Visulization applications like VTK to visualize heavy data sets in a light-weight and fast manner on the web browser.

Wizi makes it possible to deploy heavy visualizations on run heavy visualizations on a remote server or cluster and deploy them at a remote client withot heavy infrastructure cost at the client side. Wizi uses simple image delivery mechanism to achieve this.

##Supported Applications

• VTK ( 6 >= )
• More to be devloped

##Requirements

• Python 2.7 (Not tested on Python 3)

##Usage

This example uses VTK with python.

Assemble the VTK pipeline till the vtkRenderWindow & plug it to the required wizi iteractor.

Important: Do not connect the RenderWindow to vtkRenderWindowInteractor as it creates a pop up window.

import wizi
# asseble the vtk pipeline till the renderwindow.
# give the renderwindow to wizi's interactor

iren = wizi.VTKTrackBallCameraInteractor(renderwindow)
server = wizi.WiziServer(iren)
server.start() 

Open the visulization in the browser

##For Development

1. Extend the functionality to Mayavi by writing modules. Practically - any 3D application's offscreen renderwindow and Camera can be used to write a module to extend wizi's functionality to the module. Look into wizi_offscreen.py.
2. VTKTrackBallCameraInteractor is just one way of interacting with the offscreen renderwindow. More ways of interacting with renderwindow.
3. Implement "diff"-ing and compression for image delivery for faster and light-weight visualization
