bool Camera::isInCollisionBox	(	glm::vec3	transVec,
		bool	xz
	)		`[private]`

Checks whether movement moves the camera outside of the permitted bounding box.

The bounding box is decided by terrW, terrH, xzLim, yLimLo and yLimHi.

Parameters:

transVec	Vector corresponding to the translation attempted.
xz	Boolean that decides if a check for xz or y should be made.

Returns:: false if tested movement would move the camera outside of it's bounding box, otherwise true.

Note that up here means according to the camera view direction, not necessarily in world coordinates.

Parameters:

d	Amount to move the camera up.

Definition at line 135 of file camera.cpp.

void Camera::rotate	(	char	direction,

Parameters:

d	Amount to move the camera to the left (negative moves it to the right).

Definition at line 126 of file camera.cpp.

void Camera::translate	(	GLfloat	dx,
		GLfloat	dy,
		GLfloat	dz
	)

dy	Amount to move the camera along the y axis.
dz	Amount to move the camera along the z axis.

Definition at line 90 of file camera.cpp.

void Camera::uploadCamData ( GLuint program )

Uploads the camera data to the specified shader.

Parameters:

program Shader program to upload the camera information to.
