Specifies a pointer to an array of two, three, or four elements, specifying x, y, z, and w coordinates, respectively. Description The GL maintains a 3D position in window coordinates. This position, called the raster position, is used to position pixel and bitmap write operations. It is maintained with subpixel accuracy. See glBitmap, glDrawPixels, and glCopyPixels. The current raster position consists of three window coordinates (x, y, z), a clip coordinate value (w), an eye coordinate distance, a valid bit, and associated color data and texture coordinates. The w coordinate is a clip coordinate, because w is not projected to window coordinates. glRasterPos4 specifies object coordinates x, y, z, and w explicitly. Chapter 16 375
