[Particle Effects] Dust Clouds #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Feature: Particle effect addition

Purpose of feature addition: Add particle effects to represent grass/mud being 
ripped up from the tyres, possibly based on the integral of the cars velocity 
(so that when the car is heavily accelerating it will spit stuff out as if it 
is struggling for traction).
Ensure this is not too graphically intensive.

Branch affected:
/branches/graphics-test

Currently building a particle model for this purpose.

Built the particle model as well as I can, awaiting method to find when wheels 
lose traction

I guess for now I could just give you the case where the brakes are on but the 
car is still moving?

Debugging the individual friction on a wheel at any given time hasn't really 
yielded anything interesting, but it seems the possible things to look at is 
endless..

I now also have slip angle calculations 
(http://en.wikipedia.org/wiki/Slip_angle) which are part of a much broader 
formula for friction by some guy called Pacejka, but it's way over my head at 
the moment.

I'll tidy up my code and commit some (hopefully useful) functions tomorrow :)
