Matrix4.setToProjection介绍

[英]Sets the matrix to a projection matrix with a near- and far plane, a field of view in degrees and an aspect ratio. Note that the field of view specified is the angle in degrees for the height, the field of view for the width will be calculated according to the aspect ratio.
[中]将矩阵设置为具有近平面和远平面、以度为单位的视野和纵横比的投影矩阵。请注意，指定的视野是高度的角度（以度为单位），宽度的视野将根据纵横比计算。
