对图形的一些处理-some of the graphics processing

二次曲面，其功能是能够创建二次物体。通过OpenGL基于屏幕像素块所覆盖的区域对每一块覆盖的范围值进行计算，然后在RGBA模式中,OpenGL用该值与Alpha值相乘。-conicoid, and its function is to create two objects. Adoption of OpenGL-based screen pixel block area covered for each one covering the value calculated, and then RGBA model, the value of using OpenGL and Alpha value multiplication.

/* Draw circles of radius 9, 8 and 7 with the colours shown around (0,0) Draw the x and y axis Draw the diagonal line Draw the 12 by 6 quad around (0,0) When the left mouse button is pressed the diagonal line moves as shown. When the right button is pressed the diagonal line is reset to its original position The right button also toggles the direction from + to - x Pressing Esc exits the program */-/* Draw circles of radius 9, 8 and 7 with the colours shown around (0,0) Draw the x and y axis Draw the diagonal line Draw the 12 by 6 quad around (0,0) When the left mouse button is pressed the diagonal line moves as shown.
