[070704] Explosion generator created for the Unify Community Explosivo contest.

A novel aproach introduced in this article was used for the layout and expansion of the explosion. The technique is based on L-systems and fractal tree growing algorithms to simulate the expanding gasses of an explosion. Alpha blended particle rendering was choosen to give the explosion more volume as additive/multiplied particles tend to look a bit flat.

Parameters controlling the explosion are exposed and listed to the left. To change the parameters of the explosion simply click the corresponding line and drag the mouse up and down..

The parameters are:

• Branch Count - Initial Number of branches
• Branch Count Multi - Multiplier for the branch count applied for each iteration
• Max iterations - Max number of iterations (branch splits)
• Branch Life - How long a branch lives and grows
• Life Random - Life Randomnes
• Life Multi - Multiplier for Branc Life applied for each iteration
• Branch Force - How fast the branch grows
• Branch Direction x,y,z - Initial growing direction of branch
• Branch Dir Rnd Angle - Random angle offset from growing direction
• Branch Dir Rnd Multi - Multiplier for the Random growing angle applied for each iteration.
• Branch Gravity x,y,z - Branch gravity
• Particle Min Size - Particle Minimum Size
• Particle Max Size - Particle Maximum Size
