NAME

       glDrawArrays - render primitives from array data

C SPECIFICATION

       void glDrawArrays(GLenum mode, GLint first, GLsizei count);

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, GL_TRIANGLES_ADJACENCY and GL_PATCHES are
           accepted.

       first
           Specifies the starting index in the enabled arrays.

       count
           Specifies the number of indices to be rendered.

DESCRIPTION

       glDrawArrays 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 glDrawArrays.

       When glDrawArrays 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 glDrawArrays have an unspecified value after glDrawArrays 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 count 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.

       GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible with the input
       primitive type of the geometry shader in the currently installed program object.
