Title: View matrix and camera rotation (OpenGL 3.2)
Post by: Akzyl on February 11, 2013, 21:59:04
Hello.
Can you help me with a little problem i'm trying to rotate camera (you know LOK UP, LOOK DOWN, TURN LEFT, TURN RIGHT).
Based on
The Quad with Projection, View and Model matrices
http://lwjgl.org/wiki/index.php?title=The_Quad_with_Projection,_View_and_Model_matrices

i assume that i need to do something with viewMatrix but I have no idea how to go about it.

you need basic understanding on how opengl handles a matrix

http://www.khronos.org/opengles/sdk/1.1/docs/man/glLoadIdentity.xml (http://www.khronos.org/opengles/sdk/1.1/docs/man/glLoadIdentity.xml)

select matrix, load-matrix etc.

maybe that helps too : http://www.songho.ca/opengl/gl_transform.html (http://www.songho.ca/opengl/gl_transform.html)
