~Camera()

void update(float deltaTime)

void attach()

inline void reApplyScissor()

Re-applies the scissor-area defined via the viewport.

This can be useful if you changed the scissor-area and now wish to reset it.

void setScreenArea(int x, int y, int width, int height)

void setLookAt(

const fm_vec3_t &newPos,

const fm_vec3_t &newTarget,

const fm_vec3_t &newUp = {0, 1, 0}

)

Sets new camera values based on a look-at transform.

If you have an arbitrary rotation based camera prefer using ‘setPosRot’.

Parameters:

• newPos – camera eye

• newTarget – camera target

• newUp – camera up vector (+Y by default)

void setPosRot(const fm_vec3_t &newPos, const fm_quat_t &rot)

Sets a new camera by position and rotation.

If you have a look-at based camera prefer using ‘setLookAt’.

Parameters:

• pos – camera eye

• rot – rotation
