Member Function Documentation

◆ getFrustum()

std::array< Plane, 6 > Camera::getFrustum ( ) const

Returns the camera's frustum in world space.

Note
Order of the planes is: left, right, top, bottom, near, far.

◆ getFrustumCorners()

std::array< glm::vec3, 8 > Camera::getFrustumCorners ( ) const

Returns the camera's frustum corners in world space.

Note
Order of the corners is: [0] near bottom right, [1] near bottom left, [2] near top right, [3] near top left, [4] far bottom right, [5] far bottom left, [6] far top right, [7] far top left.

◆ rotation()

glm::quat Camera::rotation ( bool  ignorePitch) const

Returns the camera's rotation as a quaternion.

Parameters
ignorePitchIf true, the pitch (up/down rotation) is ignored. Good if you want to move on XZ plane only.
Returns
Quaternion representing the camera's rotation.

◆ windowResizeEvent()

void Camera::windowResizeEvent ( ResizeEvent *  ev)
overridevirtual
