getViewProjection()

glm::mat4 NewCamera::getViewProjection ( ) const

inlinenodiscard

Alias for getViewProjectionMatrix() — kept short for callsite ergonomics.

getViewProjectionMatrix()

glm::mat4 NewCamera::getViewProjectionMatrix ( ) const

inlinenodiscard

Return the combined view-projection matrix.

setAspect()

void NewCamera::setAspect	(	float	width,
		float	height )

Set the aspect ratio from pixel dimensions (modifies projection matrix).

Parameters

width	Viewport width in pixels.
height	Viewport height in pixels.

setEye()

void NewCamera::setEye

(

glm::vec3

eye

)

Set the camera eye position in world space (modifies view matrix).

Parameters

eye	World-space position.

setFov()

void NewCamera::setFov

(

float

fovyDegrees

)

Set the vertical field of view in degrees.

Parameters

fovyDegrees

Vertical FOV in degrees.

setTarget()

void NewCamera::setTarget	(	float	pitch,
		float	yaw,
		float	roll )

Set the view direction from pitch, yaw, and roll (all in radians).

Roll rotates the up vector around the forward axis, used for camera tilt during wallruns.

Parameters

pitch	Pitch angle in radians.
yaw	Yaw angle in radians.
roll	Roll angle in radians.

setUp()

void NewCamera::setUp

(

glm::vec3

up

)

Explicitly set the camera up direction, overriding setTarget's up vector.

Parameters

up	The desired up direction.

setZFar()

void NewCamera::setZFar

(

float

zFar

)

Set the far clip plane distance.

Parameters

zFar	Far clip distance.

setZNear()

void NewCamera::setZNear

(

float

zNear

)

Set the near clip plane distance.

Parameters

zNear

Near clip distance.
