I was reading a few math books and i came across a snippet where the following lines of pseudo code were used to find the lookAt vector(The forward direction) Here it is.. X_Orientation = -Sin(Heading); Y_Orientation = cos(Heading); Z = 0; FinalX_position = CurrentPosition_X+X_Orientation*SomeFactor (Like 30 ,40 or 50); FinalY_position = CurrentPosition_Y+Y_Orientation*SomeFactor (Like 30 ,40 or 50); Final_Z = CurrentPosition_Z; The co-ordinate system used is Z Axis is height and Y axis is depth... (FinalX_position ,FinalY_position ,FinalZ ) will get transalated governed by the variable "SomeFactor". But i havent understood this fully ...Why do we need -Sin,+Cos....??? Could any1 kindly explain this to me in detail?..plz Are there better ways of doing this?? Thanks in anticipation
