glMultiDrawArrays - render multiple sets of primitives from array data
void glMultiDrawArrays(GLenum mode, const GLint * first, const GLsizei * count,
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,
GL_TRIANGLES_ADJACENCY and GL_PATCHES 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 call to
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
Vertex attributes that are modified by glMultiDrawArrays have an unspecified value after
glMultiDrawArrays returns. Attributes that aren't modified remain well defined.
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.
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.
