Return true if object transformation is set

void tlp::Camera::initGl ()

Init Gl parameters

void tlp::Camera::initLight ()

Init light

void tlp::Camera::initModelView ()

Init modelview

void tlp::Camera::initProjection (bool reset = true)

Init projection with the scene viewport. Load identity matrix if reset is set as true

void tlp::Camera::initProjection (const Vector< int, 4 > & viewport, bool

reset = true)
Init projection with the gived viewport. Load identity matrix if reset is set as true

bool tlp::Camera::is3D () [inline]

Return if the camera is a 3D one

void tlp::Camera::move (float speed)

This moves the camera forward or backward depending on the speed
