GLMULTIDRAWARRAYS(3G)						    OpenGL 3.3						     GLMULTIDRAWARRAYS(3G)

NAME

       glMultiDrawArrays - render multiple sets of primitives from array data

C SPECIFICATION

       void glMultiDrawArrays(GLenum mode, const GLint * first, const GLsizei * count, GLsizei primcount);

PARAMETERS

       mode
	   Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES,
	   GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY and
	   GL_TRIANGLES_ADJACENCY are accepted.

       first
	   Points to an array of starting indices in the enabled arrays.

       count
	   Points to an array of the number of indices to be rendered.

       primcount
	   Specifies the size of the first and count

DESCRIPTION

       glMultiDrawArrays specifies multiple sets of 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 glMultiDrawArrays.

       glMultiDrawArrays behaves identically to glDrawArrays() except that primcount separate ranges of elements are specified instead.

       When glMultiDrawArrays 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.

       Vertex attributes that are modified by glMultiDrawArrays have an unspecified value after glMultiDrawArrays returns. Attributes that aren't
       modified remain well defined.

NOTES

       GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are available only if the GL version is
       3.2 or greater.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if primcount is negative.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is
       currently mapped.

SEE ALSO

       glDrawElements(), glDrawRangeElements()

NAME

       glMultiDrawElements - render multiple sets of primitives by specifying indices of array data elements

C SPECIFICATION

       void glMultiDrawElements(GLenum mode, const GLsizei * count, GLenum type, const GLvoid ** indices, GLsizei primcount);

PARAMETERS

       mode
	   Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES,
	   GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY and
	   GL_TRIANGLES_ADJACENCY are accepted.

       count
	   Points to an array of the elements counts.

       type
	   Specifies the type of the values in indices. Must be one of GL_UNSIGNED_BYTE, GL_UNSIGNED_SHORT, or GL_UNSIGNED_INT.

       indices
	   Specifies a pointer to the location where the indices are stored.

       primcount
	   Specifies the size of the count array.

DESCRIPTION

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

       glMultiDrawElements is identical in operation to glDrawElements() except that primcount separate lists of elements are specified.

       Vertex attributes that are modified by glMultiDrawElements have an unspecified value after glMultiDrawElements returns. Attributes that
       aren't modified maintain their previous values.

NOTES

       GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are available only if the GL version is
       3.2 or greater.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if primcount is negative.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer
       object's data store is currently mapped.
