Background (1) - Overview
Computer Graphics Metafile
ISO (International Organization for Standardization) standard for
vector and composite vector/raster picture definition since 1987.
HyperText Markup Language
The cornerstone of the W3C's open web platform; a framework
designed to foster innovation and develop the full potential the
web has to offer.
Web Graphics Library
A JavaScript API for rendering interactive 3D computer graphics and 2D
graphics within any compatible web browser without the use of plug-ins.

Background (2) – HTML5
• HyperText Markup Language (HTML)
• Core technology of the Internet used for structuring and presenting content
on the World Wide Web
• Not owned, non-proprietary
• HTML5 adds many new syntactic features including:
• <video>, <audio> and <canvas> elements
• Additionally the integration of the SVG graphics format
• The new features are primarily designed to enable multimedia delivery
without using plug-ins
• Device-independent design to work on broad array of devices PCs,
smartphones and tablets
• Introduces several application programming interfaces (APIs) for complex web
applications

Background (3) – WebGL
• JavaScript API for rendering interactive 3D and 2D graphics
• Designed and maintained by the non-profit Khronos Group
• Completely integrated into all the web standards of the
browser permitting GPU acceleration.
• No plug-in required in a compatible web browser
• WebGL is widely supported in modern browsers.

• ActiveX weaknesses
• Has to be installed on the target computer
• Strongly criticized for security problems
• ActiveX Browser Support
• Microsoft Edge browser - Support dropped
• Good indication the technology will phased out
• Chrome and Firefox still support ActiveX
• Future strategy unknown
• A solution without the reliance on a plug-in will be beneficial
New Technology ActiveX alternative?
