For orthographic parallel projection:
glOrtho(left, right, bottom, top, near, far);
glOrtho2D(left, right, bottom, top);
Here left, right define the x-direction extents, bottom, top define y-direction extents and near, far define the z-direction extents of the view volume. gluOrtho2D is exactly like glOrtho, but with near = -1 and far = 1. That is, gluOrtho2D views points that have z-value between -1 and 1. Usually, gluOrtho2D is used when drawing two-dimensional figures that lie in the xy-plane, with z = 0.
What is reflection? The reflection is actually the transformation that produces a mirror image of an object. For this use some angles and lines of reflection.
What is Aspect ratio? The ratio of vertical points to the horizontal points essential to produce length of lines in both directions of the screen is known as the Aspect ratio.
what is refresh buffer/ identify the content and organisation of the refresh buffer for the case of raster display and vector display.
examples and equation of reflection
Consider at line segment AB in the Figure k, parallel to the z-axis along with end points A (3, 2, 4) and B (3, 2, 8). Perform a perspective projection on the z = 0 plane from the
