Detailed Description

The class for controlling the camera. The interface is specified in yaw, pitch, and roll ("human" coordinates) but all interpolation is done with full rotation matrices and quaternions.

"MoveXXX" functions move the camera correcting for time, so the input to "MoveXXX" functions is a velocity.

"SetXXX" functions set the position of the camera, so the input is a rotation or

"PanXXX" functions move the camera over time on a path. The Pan functions, when the panning is complete, will call the camera listeners.

Member Function Documentation

void lilith3d::Camera::MoveCamera	(	float	xVelocity,
		float	yVelocity,
		float	zVelocity
	)

Move the camera relative to the current position. The change is in terrain (world) coordinates.

void lilith3d::Camera::MoveCameraAxial2D	(	float	axialVelocity,
		float	perpVelocity
	)

Move the camera in camera coordinates - an axial velocity is ahead, and the perpendicular to the side. Moves without changing the camera Z.

void lilith3d::Camera::MoveCameraAxial3D

(

float

axialVelocity

)

Move the camera in camera coordinates - an axial velocity is ahead, and the perpendicular to the side.

void lilith3d::Camera::PanCamera	(	float	x,
		float	y,
		float	z,
		float	yaw,
		float	pitch
	)

Smoothly move the camera by interpolation.

void lilith3d::Camera::PanCamera	(	U32	millisec,
		float	x,
		float	y,
		float	z,
		float	yaw,
		float	pitch
	)

Smoothly move the camera by interpolation, using a specified time.

float lilith3d::Camera::CalcPitch

(

)

Calculate the latitude of where the camera is looking. This coresponds to pitch, but isn't an Euler Angle representation.

float lilith3d::Camera::CalcYaw

(

)

Calculate the longitude of where the camera is looking. This coresponds to yaw, but isn't an Euler Angle representation. Longitude 0 is the x axis.
