Better Air friction Calculations

Postby Mystery » Thu Mar 04, 2010 1:04 pm

To my knowledge Airfriction works on the basis of the angles of vertices compared to the angle of travel. So a shape with many internal components would be slowed down significantly more then a single polygon.

A much more realistic approach could be to calculate the external vertices and treat it as a single polygon.

To my knowledge fixating objects together made Algodoo treat it as a single object (More then less) my guess is this would only be an adding on to the current fixation codes.

I also once posted a topic because of wrong air friction while working on an artillery. it doesn't deal with the shape itself but with the direction the object moves to.

It's very good that you mention it. Would be very cool to see those air friction "problems" to be fixed.

This is definitely a good idea. I support it 100%
But how would the program know which vertices are external?

I had to do a double take when I saw who posted this. It's a good suggestion.
:clap: Hooray for Mystery!
