   Calculate new matrix position values
  I have an objectxpos,ypos,zposi have the angles at which it travellingxangle,yangle,zanglei have the velocity at which it travelsvelusing these what would be the methodology to calculate its new positionor a link if you have one, I dont need the code but rather the methodolgy to calculate the new position with the necessary deviations  
  Seems like thats pretty much the same problem, I have. ;-) In case you found a solution, could you please keep me posted?Thanks,TroneX    LightBrain website relaunched, BomberFUN only USD 9.99visit http://www.lightbrain.de;  check out the tutorials on this very site dealing with matrices and stuff. not a bad idea when you plan to render those graphics in 3d anyway  ;  oh and btw... wouldnt it be easier to have the speed represented as a vector anyway? that would make it a simple mattr of adding the speedvector to the positionvector. and besides a speedvector is much more convient for other calculations aswell.  ;  Eelco, i agree with you. Is there a particular article here or anywhere else that deals with that?thanks,nick  ;  store your velocity vector. When the object turns, multiply the velocity vector by the relative rotation matrix. When the object accelerates/decelerates, multiply the velocity vector by a scaling matrix. To move an object, make a translation matrix out of the velocity vector and multiply the position by the translation matrix.    How appropriate. You fight like a cow.  ;  If you have position P and direction D and velocity v, then the new position P'' is given by:  P'' = P + D*v;  Does anyone have a link or book recommendation that thoroughly  shows examples and explanation of calculating all of these formulas?  ;  http://www.google.comsearch for "rotation matrix", "scaling matrix", "translation matrix".    How appropriate. You fight like a cow.  ;  So out of curiosity I understand to get a new position i would multiply a velocity matrix by the objects position matrix to get his new position.But if an object lets say has a velocity of 5.0 how would I define his matrix. any pointers?
