Constructor & Destructor Documentation

Camera()

Camera::Camera ( Vec3 position, float moveSpeed = 0.015f, float mouseSens = 0.15f, Vec3 worldUp = Vec3(0.0f, 1.0f, 0.0f) )

inline

Construct a camera at position with speeds/sensitivity and an up axis.

Parameters

position	Initial world position.
moveSpeed	Linear speed per update (world units per frame).
mouseSens	Mouse sensitivity in degrees per pixel.
worldUp	World up vector used to build the orthonormal basis.

Member Function Documentation

disableMouse()

void Camera::disableMouse ( )

inline

Disable mouse-look and reset the internal cursor cache.

Resets the cached mouse position so the next mouseMove() call establishes a new reference without producing a jump.

enableMouse()

void Camera::enableMouse ( )

inline

Enable mouse-look processing in mouseMove().

mouseMove()

void Camera::mouseMove ( float xPosition, float yPosition )

inline

Update yaw/pitch from a new cursor position.

Parameters

xPosition	New cursor X in window coordinates (pixels).
yPosition	New cursor Y in window coordinates (pixels).

When enabled, computes pixel deltas since the previous call, scales them by mouseSens, applies them to yaw/pitch, clamps pitch to [-89,89], and rebuilds the basis. The first call after enabling only seeds the cache.

moveBack()

void Camera::moveBack ( bool b )

inline

Toggle backward motion along the view direction.

moveFront()

void Camera::moveFront ( bool b )

inline

Toggle forward motion along the view direction.

moveLeft()

void Camera::moveLeft ( bool b )

inline

Toggle motion to the left (strafe).

moveRight()

void Camera::moveRight ( bool b )

inline

Toggle motion to the right (strafe).

updatePosition()

void Camera::updatePosition ( )

inline

Integrate position one step based on active movement flags.

Applies moveSpeed along direction and right depending on which toggles are set. Call this once per frame.

viewMatrix()

Mat4 Camera::viewMatrix ( )

inline

Compute the view (camera) matrix.

Returns

Right-handed look-at matrix from position toward forward direction.
