view up vector
In 3D computer graphics, the vector that defines which direction is 'up' for the camera or view transformation.
Setting the view up vector along the Y-axis makes the Y-axis the up direction.
The view matrix is the transformation matrix derived from the camera position, look direction, and view up vector.
View direction is the forward-looking direction of the camera, while the view up vector defines the upward orientation.
A compound of ビュー (view), 上方向 (up direction), 定義 (definition), and ベクトル (vector), directly translating the English term 'view up vector'.
