gluLookAt
I''m having some problems with the camera command "gluLookAt". Well not really a problem, it''s more of a lack of information. I was wondering if there might be some page or someone that can explain 2 me what all the numbers inside the function does, well I know what they do, but what they determine.
gluLookAt(0.0f, 0.0f, 10.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f);
I know that the "10.0f" defines the camera position along the "Z-axis" but what do the other define??
Here''s what you need, copy-pasted straight from the documentation:
The gluLookAt function defines a viewing transformation.
void gluLookAt(
GLdouble eyex,
GLdouble eyey,
GLdouble eyez,
GLdouble centerx,
GLdouble centery,
GLdouble centerz,
GLdouble upx,
GLdouble upy,
GLdouble upz
);
Parameters
eyex, eyey, eyez
The position of the eye point.
centerx, centery, centerz
The position of the reference point.
upx, upy, upz
The direction of the up vector.

);
