Description: 将投影变换矩阵存储到一个一维数组中，与函数glFrustum，glOrtho，gluPerspective的相应参数相同，并比较当前投影矩阵和用所设计的函数所得结果。在屏幕上输出两个矩阵并进行比较。可使用glGetFloatv(GL_PROJECTION_MATRIX, ...)获得当前投影矩阵。-projection matrix storage to a one-dimensional arrays, and functions glFrustum. glOrtho, gluPerspective same as the corresponding parameters, and to compare the current projection matrix, and the use of design as a function of the results. On the screen two output matrix and compared. Use glGetFloatv (GL_PROJECTION_MATRIX. ...) access to current projection matrix.

Description: Torus
Display a static picture of a torus and the coordinate system axes.
Instead of using a primitive GL function (such as glOrtho or glFrustum) to set the viewing volume, it instead uses gluPerspective. gluPerspective must be done when the matrix mode is GL_PROJECTION.
Instead of using translates and rotates to position the objects into the view volume, it instead uses gluLookAt to position and orient the camera so that it is looking at the objects. gluLookAt must be done when the matrix mode is GL_MODELVIEW.
Shows that the combination of gluPerspective and gluLookAt is considerably more intuitive than the more primitive mechanism of glFrustum and plain object transformations.
Draws the torus using the fancy glutWireTorus function (which internally calls glVertex a zillion times).
