View Full Version : Viewing using Eye Points

10-24-2017, 06:02 PM
Hi, I have made a maze and am trying to view it. In order to view the maze I am told to implement the following functions:

mat4 look_at(GLfloat eyex, GLfloat eyey, GLfloat eyez,
GLfloat atx, GLfloat aty, GLfloat atz,
GLfloat upx, GLfloat upy, GLfloat upz);
mat4 frustum(GLfloat left, GLfloat right, GLfloat bottom, GLfloat top,
GLfloat near, GLfloat far);

Using these functions I am trying to view my maze at the center from above, and "fly" around it in a circle. Next, I need to "fly" down to the entrance of the maze by changing the viewpoint slowly until it is right in front of the entrance.

Here's what I'm struggling with - how to implement these functions. I don't even know where to start. Also, once implemented - what to set each argument in the functions as for the different viewpoints. Any help is appreciated!

If anyone could provide me with the implementation of GluLookAt I'd be very appreciative! Direct code or link would be great.
