GLUORTHO2D: Specify a two-dimensional world coordinate system glvertex*: Select a coordinate location. The function must be placed between Glbegin/glend Glbegin (gl_points): Draw one or more points, each specified in the Glvertex function. The end string is finally ended by the Glend statement. Glbegin (Gl_lines): Displays a set of straight line segments whose endpoint coordinates are specified in the Glvertex function. The end string is finally ended by the Glend statement. Glbegin (Gl_line-strip): Displays the polyline glbegin (gl_line-loop) specified for Gl_lines same structure: Displays the closed polyline specified with the same structure as gl_lines. glrect*: Displays a fill area on the XY plane Glbegin (Gl_polygon): Displays a fill polygon whose vertices are given in Glvertex and terminated by the Glend statement. Glbegin (gl_triangles): Displays a set of fill triangles that describe the same structure as Gl_polygon Glbegin (Gl_triangle-strip): Displays a filled triangle with the same description structure as the Gl_polygon. Glenableclientstatef (Gl_vertex_array): Active OpenGL vertex array facilities glvertexpointer (size, type, stride, array) : Specifies an array of coordinate values gldrawelements (Prim,num.type,array): Displays a specified primitive type from the array data glnewlists (ListID, Listmode): Defines a set of commands as a display table, End glgenlists with glendlist statement: Generates one or more display table identities Glislist: Determines whether a display table identifies a query function that is used Glcalllist: Executes a display table Gllistbase: Specifies the displacement of the display table identity array glcalllists: Executes multiple display tables Gldeletelists: Deletes the specified list of displayed tables glrasetrpos*: Specifies a two-dimensional or three-dimensional current position for the frame cache. This position is used as a reference glbitmap (W, H, x0, y0, xshift, yshift, pattern) for bitmap and pixel graph patterns: Specifies the bitmap pattern to map to the pixel location corresponding to the current position gldrawpixels (W, H, type, format, pattern): Specifies the pixel graph pattern to map to the pixel location corresponding to the current position Gldrawbuffer: Select one or more cache glreadpixels to store the pixel map: deposit A pixel in the specified array glcopypixels: Copy a pixel from one cache to another GLLOGICOP: Select a logical operation after activating with constant GL_COLOR_LOGIC_OP to combine the two pixels group Glutbitmapcharacter (font, char) : Select a font and a bitmap profile character to display glutstrokecharacter (font, char): Select a font and a contour character to display Glutreshapefunc: Specifies the work when the display window size changes
