Camera view matrix
Author
my cameras data sturcture is :
pos : x, y, z
lookvector : x, y, z
i want to set view from this camera. I know that I must use a
transilate and rotate matrix but which...
please help
If your using openGL try using the gluLookat. It allows you to position and move a camera by specifing a look vector for the direction the camera is to point in and a position for the camera in 3D space. Make sure you include the OpenGL utlility libary though (glu.h) and glu32.lib
Hope this helps

are u using directx or openGL ?
its quite easy ..
if u are using dx, just read up some of the sdk samples
like the billboard or dolphin. . you can get
some camera code for there. .
{ Stating the obvious never helped any situation !! }

I''m using openGL, but first I want to understand how it ( transform to camera coord. )works
I want to see a that matrix. View Matrix = rotation * transilate.
and I know, that transilate matrix is:
1 0 0 0
transilate = 0 1 0 0
0 0 1 0
-px -py -pz 1
[ px, py, pz ] - camera position coord. but....
RotateMatrix = ???
