Posted 31 Mar 2012Ok ButchDean, i know that my memory is finite but when i say "infinite" i mean a way in which i redraw terrain when it finished. Kilorn i will review tutorials about how i draw terrain, but, and forgive me for my insistence , what about xna vectors it is start from (0, 0, and 0) and what about force that start from position of object.
Posted 30 Mar 2012I will resist the urge to split hairs on those answers, but here goes. If you are aware of Newtonian Dynamics what is it about XNA's Vector3 type would be unsuitable for representing, say, velocity?
Thank you for your patience ... I do not speak English so I find some difficulty in writing and expressions.
For your question, I thought that all xna vectors starting from the (0,0,0) but the force is not the case. It starts from the position of the object.
So I want to create a new vector's class that consists of a start point and end point and the angles formed with axes, but I want to make sure the issue of xna vectors before I begin. I am having a another problem with the vectors and determine the direction of it. I wanted to know how to draw floor of the airport and make it infinite (but these issues had another question)
Posted 29 Mar 2012ok....1. velocity is rate of change of displacement over time and acceleration ia rate of change of velocity over time.
2. becuse acceleration is derivative of velocity and velocity is derivative of displacement.
3. Newton’s second law says that an acceleration of an object is due to a net external force
applied to the object. (F=m*a)
4. Integration is the opposite of differentiation that is, if i integrate displacement i get on velocity and if i integrate velocity i get on acceleration.
Posted 29 Mar 2012I want to simulate the airplane that act on it four aerodynamic forces and move accordingly. In other words i want to use Newton's second law of motion (and calculate the linear and angular velocity for the airplane). This is my aim of "physical model"
Posted 28 Mar 2012But these lessons do not learn how to build a physical model or I wrong??
