glMultiDrawArrays — render multiple sets of primitives from array data
Specifies what kind of primitives to render.
GL_POLYGON are accepted.
Points to an array of starting indices in the enabled arrays.
Points to an array of the number of indices to be rendered.
Specifies the size of the first and count
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
glMultiDrawArrays behaves identically to glDrawArrays except that
separate ranges of elements are specified instead.
glMultiDrawArrays is called, it uses
count sequential elements from each
enabled array to construct a sequence of geometric primitives,
beginning with element
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
glMultiDrawArrays have an
unspecified value after
glMultiDrawArrays returns. For example, if
GL_COLOR_ARRAY is enabled, the value of the current color is
glMultiDrawArrays executes. Attributes that aren't
modified remain well defined.
glMultiDrawArrays is available only if the GL version is 1.4 or greater.
glMultiDrawArrays is included in display lists. If
glMultiDrawArrays is entered into a
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.
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.
