rightThe X coordinate of the right side of the near projection plane in view space.
bottomThe Y coordinate of the bottom side of the near projection plane in view space.
topThe Y coordinate of the top side of the near projection plane in view space.
zNearZ distance to the near plane from the origin in view space.
zFarZ distance to the far plane from the origin in view space.
frustumPlanesFrustum planes struct that contains the view space coordinates of that define a viewing frustum.

戻り値

Matrix4x4 A projection matrix with a viewing frustum defined by the plane coordinates passed in.

説明

This function returns a projection matrix with viewing frustum that has a near plane defined by the coordinates that were passed in.

The corners of the near plane of the viewing frustum of the projection matrix are as follows:
top-left : (left, top, zNear)
top-right : (right, top, zNear)
bottom-right : (right, bottom, zNear)
bottom-left : (left, bottom, zNear)
