Member Function Documentation

virtual void Moteur3D::Camera::ApplyTransformation (   )  [virtual]

Applies the current transformation to the OpenGL's modelview matrix. This is a graphical-only function that should only use gl stuff. Implements Moteur3D::SGTransformation.

void Moteur3D::Camera::CalcTrans (   )  [protected]

Calculates the current transformation matrix from the Camera's coordinates and view destination. Used by ApplyTransformation only.

Vector3 Moteur3D::Camera::GetDestination (   )  [inline]

Returns the Camera's current destination. Returns: Camera's position vector.

Vector3 Moteur3D::Camera::GetPosition (   )  [inline]

Returns the Camera's current position. Returns: Camera's position vector.

void Moteur3D::Camera::LockView (   )  [inline]

Locks the view to the current destination position, which is set by calling LookAt().

void Moteur3D::Camera::LookAt (  Vector3  destination  )

Makes the Camera look at the desired coordinates. Parameters: destination  Coordinates Vector

Camera& Moteur3D::Camera::operator= (  const Camera &  c  )  [inline]

Affectation operand. Parameters: c  Camera to copy data from Returns: this Camera

void Moteur3D::Camera::SetPosition (  Vector3 *  pos  )

Sets the Camera's X, Y and Z position. If the Camera is locked on an object, it will keep on looking at it. Parameters: pos  position vector that will REPLACE the current camera's position.

void Moteur3D::Camera::Translate (  Vector3  v  )

Translates the Camera on its X, Y and Z axis at the same time. If the Camera is locked on an object, it will keep on looking at it. Parameters: v  translation vector, to ADD to the current camera's position.

void Moteur3D::Camera::TranslateX (  float  x  )

Translates the Camera on its X axis. If the Camera is locked on an object, it will keep on looking at it. Parameters: x  translation distance on the X axis

void Moteur3D::Camera::TranslateY (  float  y  )

Translates the Camera on its Y axis. If the Camera is locked on an object, it will keep on looking at it. Parameters: y  translation distance on the Y axis

void Moteur3D::Camera::TranslateZ (  float  z  )

Translates the Camera on its Z axis. If the Camera is locked on an object, it will keep on looking at it. Parameters: z  translation distance on the Z axis

void Moteur3D::Camera::UnlockView (   )  [inline]

Unlocks the view that was previously locked by LockView().
