パラメーター

left The X coordinate of the left side of the near projection plane in view space.
right The X coordinate of the right side of the near projection plane in view space.
bottom The Y coordinate of the bottom side of the near projection plane in view space.
top The Y coordinate of the top side of the near projection plane in view space.
zNear Z distance to the near plane from the origin in view space.
zFar Z distance to the far plane from the origin in view space.
frustumPlanes Frustum 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)
