How do I position a 2D camera in OpenGL?
- by Elfayer
I can't understand how the camera is working.
It's a 2D game, so I'm displaying a game map from (0, 0, 0) to (mapSizeX, 0, mapSizeY).
I'm initializing the camera as follow :
Camera::Camera(void)
: position_(0.0f, 0.0f, 0.0f), rotation_(0.0f, 0.0f, -1.0f)
{}
void Camera::initialize(void)
{
glMatrixMode(GL_PROJECTION);
…
