common points within the plane.(2) lines and planes intersect that line and plane have only one common point (vertical is also a kind of intersection).(3) lines and planes are parallel, i.e. straight lines and planes have no common points.The relation between plane and planeThe relationship between plane and plane in 3-D space is similar to the relationship between lines and lines in 2-dimensional space:(1) Two planar intersections (coincident is a special intersection).(2) Two planes parallel.

with only a small number of function calls. The uses the previously defined PT array to implement the three steps in the following program example. Glenableclientstate (Gl_vertex_array); Glvertexpointer (3, Gl_int, 0, PT); Glubyte Vertindex [] = (6, 2, 3, 7, 5, 1, 0, 4, 7, 3, 1, 5, 4, 0, 2, 6, 2, 0, 1, 3, 7, 5, 4, 6); Gldrawelements (Gl_quads, Gl_unsigned_byte, Verindex);The First command, Glenableclientstate (Gl_vertex_array), activates the client's ability (in this case, the vertex array)

Algorithm Description:　　For a general position ellipse, for example, you can pan the center to the coordinate origin, determine the ellipse pixel point set at the standard position of the center at the origin, and then pan to the position, transforming the problem into a standard position of the ellipse's drawing problem.If the long and short axes of an ellipse are not parallel to the axis x and y, then the rotation coordinate transformation can be used to transform the problem into a standard p

As the heat of summer approaches, temperatures are now rising markedly. Summer notebook friends often encounter a notebook due to indoor temperature is too high to cause all kinds of computer crashes or blue screen failure, the main reason for the high temperature of the notebook is that the notebook heat is bad, especially some use a notebook for a year or two, the probability of failure in summer is many, the reason is mainly due to the external tem

The arithmetic of digital differential analysis drawing line in computer graphicsModern computer graphics, our programmers often encounter drawing programming problems, and now there are a lot of drawing API, in other words, the graphical API is very rich, from TC graphic to Windows gdi/gdi+, as well as the cross-platform open standard OpenGL. These APIs provide

information about the algorithm, see Chapter 1 "hide and hide ". Dot Matrix and vector Lattice charactersIn the dot matrix font, each character is represented by a bitmap (as shown in Figure 2.5) and expressed in a matrix called a character mask. Each element is a binary number, if this bit is 1, it indicates that the stroke of the character passes through this bit, And the pixel is set to the color of the character. If this bit is 0, it indicates that the stroke of the character does not pa

command to set the net colorused for these color caches:Glclear (Gl_color_buffer_bit);We can also use the Glclear function to set the initial value of other caches that are valid in OpenGL. They are the cumulative cache (accumulation buffer) that holds the harmonic color information, the depth cache (depth buffer) that holds the depth value of the scene object (distance from the viewing location), and the template cache (stencil buffer) that defines the gra
