Visualization Engine for .NET (C# and Visual Basic)

This section describes the 2d and 3d visualization capabilities of ILNumerics. The rendering engine has been redesigned to better adapt the development of interactive technical applications and scientific visualizations with C# and .NET. It now provides many features of modern game engines, abstracting away platform specifics and the low level details of computer graphics.

Following features are realized in the 2d and 3d visualization API:

  • Simple setup
  • Simple and efficient scene definition
  • Seamless integration with ILNumerics efficient memory management
  • Reusable scenes, MVC model
  • Multiple driver support, robust auto-selection of OpenGL or GDI+
  • Shader support
  • Clean multithreading model
  • Transparent memory buffer sharing
  • One file, managed only deployment
  • Optimized for fast general 3D visualizations
  • Optimized for scientific data plotting (line plots, surface plots, contour plots)
  • Optimized for application development, interactivity and extensibility
  • Dynamic capabilities, everything is updateable at runtime

Quick Start Guide

A quick start guide for the Visualization Engine is given in the Getting Started Section. Visit this guide and come back afterwards!

Default Interaction with ILPanel

In general, if not configured otherwise, the default mouse interaction on all scene objects in ILNumerics Visualization Engine works as follows:


Left mouse button: drag -> Rotation

Right mouse button: drag -> Pan

Mouse wheel -> Zoom In / out

Left Click -> Selection

Double Click -> Reset view

CTRL + Left button + drag -> Rotate around LookAt axis

SHIFT + drag -> fine adjust

ALT + drag -> restrict to horizontal or vertical direction

Interactive Web-Examples

Note, in the following documentation sections we will concentrate on creating scenes instead of windows. We will utilize the ILNumerics web components in the client browser. If in a code area a scene is created, it is converted to a visual image on the fly and immediately displayed. Try modifying the code and generate your own visualizations on demand!

Read more about visual code examples and the ILNumerics web component in the Web Examples How to.
