   Tranforming Obstacles to characters local space
  Yeah, so im on the final steering behaviour for my game. Its obstacle avoidance. It isnt really that hard, but all the methods i look up say its best to transform the obstacles to the characters local space. I dont know how to do this. Can anyone fill in the blanks please? Cheers.   
  From what I have learned you take the objects transform and multiply it by the characters inverse transform. The transforms are their respective WORLD transforms.   ;  When you say objects transform, im assuming you mean the objects world matrix?   ;  Yes, just the inverse object to world space matrix. You may not need to do that though.You could use the dot product between the target vector and your "right" vector to determine whether to steer right or left and by how much.
