Dear all,<br><br>I'm trying to transform my mesh surface. Here is the exact order I operate it.<br><br>First, I scale and rotate it. Then, I get the world coordinates of a specific point on it. And I compute the display coordinates of this point. During this process, I keep this mesh surface off screen since it is generated.<br>
<br>The problem is, I just scale and rotate it slightly. But the display coordinates are significantly changed. Is this because I keep it off screen? If so, how can I solve this?<br><br>I'll be really appreciate if anyone can give me some advice.<br>
<br>Best wishes<br>Wenlong<br>
