Fire Simulator

[ashimo]

This example displays flames by simulating them mathematically, not just by showing a series of precomputed images. The fire in this demo is procedurally generated locally on the client machine. It is not an animated series of pictures, but instead a complex mathematical function that has been downloaded to your computer as programming code.

Description
This demo shows the combination of high level programming constructs for graphical events with fast, pixel-level graphics control. It also demonstrates how high-level constructs can be created by the programmer if they are needed and don't currently exist.

The fire itself combines:

• Random number generator
  
• Spectrum
  
• Displacement Mesh
  
• Blur Algorithm
  

The algorithm contains:

• A distortion field to swirl the fire
  
• A blur that spreads the flame
  
• A flame generator
  
• A dispersion filter
  

Note that any user modifications are handled at the user machine, without server interaction.

Instructions

• Select and de-select the various checkboxes that relate to the algorithm for drawing / animating the fire. Alterations of these boxes change the dynamics of the fire without needing to transmit or receive any additional instructions or pictures from the network server.
  
• You can use the check boxes to turn on and off the convection and dispersion, replace the jets with a checkerboard pattern, and turn the animation on and off.
