java - Math behind a 3rd person camera -


I am trying for some time now and I think nothing about the third person's camera . I just want to create a simple 3 person camera but it becomes difficult because I am in 3D. So far, I can do a camera on 1 plane, but after that it's messed up. If I know any person then I am using libgdx with model libgdx.

I do not need to give you codes for this, I just need help about the information in which I have information. I know the velocity in x and z, the rotation of the object x y z, and its position at x y z I can keep an eye on the camera for the object, so what I have to do, behind it and in the after it does not matter what the orientation is for the object. Any link or explanation is highly appreciated :)

Solution:
In the comment, Xoppa posted a link to its tamper proof The camera provides and it's amazing because it was not an answer, so I accepted it, but what did I want for it? In response to this question, Expo gets all credit links, it is easy to find.

I will update the position of the player after each frame: 

  camera.up.set (0,1,0); // Be sure to make sure // if it is necessary // always after the lookAt () call of the last frame camera.exion.set (player.position) .add (-UNITS_BACK, UNITS_UP, 0). Totate (vector 3.up, player.engal); camera.lookAt (player.position); Camera.update ();   
 Where  player.angle  is the number of counter-clock, facing the player from the X-axis.  
 This is a simple exit point. You probably want to exclude the movement by limiting that speed on which the camera can be transferred or it can give the movement of the second position in the direction of this goal and the second rotating movement.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
