Derive the projection matrix for an image plane at z = 0 with the camera at(0,0,−1) pointing down the negative z-axis. The viewing plane is a squarewindow with height and width in the range [−1,1].Given the following coordinates of a pyramid, project the points of the pyramidonto the image plane using the projection matrix in part 1.D =0 0 −1 0 11 0 0 0 0−4 −3 −4 −5 −4(c) Plot the points as they would appear on the image plane. This will strictly bea 2D plot. Do not plot the points that would be occluded by visible faces ofthe cube.
