fglDrawArrays(3G)	       OpenGL Reference		     fglDrawArrays(3G)

NAME
     fglDrawArrays - render primitives from array data

FORTRAN SPECIFICATION
     SUBROUTINE fglDrawArrays( INTEGER*4 mode,
			       INTEGER*4 first,
			       INTEGER*4 count )

PARAMETERS
     mode   Specifies what kind of primitives to render.  Symbolic constants
	    GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES,
	    GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_QUAD_STRIP,
	    GL_QUADS, and GL_POLYGON are accepted.

     first  Specifies the starting index in the enabled arrays.

     count  Specifies the number of indices to be rendered.

DESCRIPTION
     fglDrawArrays specifies multiple geometric primitives with very few
     subroutine calls. Instead of calling a GL procedure to pass each
     individual vertex, normal, texture coordinate, edge flag, or color, you
     can prespecify separate arrays of vertices, normals, and colors and use
     them to construct a sequence of primitives with a single call to
     fglDrawArrays.

     When fglDrawArrays is called, it uses count sequential elements from each
     enabled array to construct a sequence of geometric primitives, beginning
     with element first. mode specifies what kind of primitives are
     constructed, and how the array elements construct those primitives. If
     GL_VERTEX_ARRAY is not enabled, no geometric primitives are generated.

     Vertex attributes that are modified by fglDrawArrays have an unspecified
     value after fglDrawArrays returns. For example, if GL_COLOR_ARRAY is
     enabled, the value of the current color is undefined after fglDrawArrays
     executes. Attributes that aren't modified remain well defined.

NOTES
     fglDrawArrays is available only if the GL version is 1.1 or greater.

     fglDrawArrays is included in display lists. If fglDrawArrays is entered
     into a display list, the necessary array data (determined by the array
     pointers and enables) is also entered into the display list. Because the
     array pointers and enables are client-side state, their values affect
     display lists when the lists are created, not when the lists are
     executed.

ERRORS
     GL_INVALID_ENUM is generated if mode is not an accepted value.

     GL_INVALID_VALUE is generated if count is negative.

     GL_INVALID_OPERATION is generated if fglDrawArrays is executed between
     the execution of fglBegin and the corresponding fglEnd.
