Advanced

This page provides links to a number of advanced topics. We mean aspects or possibilities of EJS authoring that are already there (i.e. they are not hidden), but most people do not know or use.

Examples

• Use the available digital libraries to find examples
• Specially the OpenSourcePhysics collection at Compadre for Physics simulations

Description

• Import HTML pages created with your favorite editor
• Built-in translation feature for Description pages

Model

• Real time variable (This is a new feature stating in some releases of EJS 4.3.7.)
• Using your own files
  • Using users' JAR libraries
  • Adding Import statements
  • Data files
• ODE editor
  • Preliminary code
  • Adaptive step solvers
    • Reading the step size
    • Error handling code
  • Advanced dialog
    • Synchronization
    • Internal step size
    • Memory
  • Solving DDE (Delay Differential Equations)
• Events
  • Types of events
  • Zeno effect action
• Model Elements
  • Function and DIfferentiable Function
  • Statistics
  • Parallel computing
  • Hardware elements

View

• Custom view elements
• Video element (requires Xuggle)
• 3D views:
  • Primitives, Groups, Rotations, and VRML objects
  • toSpaceFrame() and toBodyFrame()

Running Simulations

• Flow chart of the execution of a simulation created with EJS
