6 glDrawArrays - render primitives from array data
7
9 void glDrawArrays(GLenum mode, GLint first, GLsizei count);
10
12 mode
13 Specifies what kind of primitives to render. Symbolic constants
14 GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES,
15 GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP,
16 GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY,
17 GL_TRIANGLES_ADJACENCY and GL_PATCHES are accepted.
18
19 first
20 Specifies the starting index in the enabled arrays.
21
22 count
23 Specifies the number of indices to be rendered.
24
26 glDrawArrays specifies multiple geometric primitives with very few
27 subroutine calls. Instead of calling a GL procedure to pass each
28 individual vertex, normal, texture coordinate, edge flag, or color, you
29 can prespecify separate arrays of vertices, normals, and colors and use
30 them to construct a sequence of primitives with a single call to
31 glDrawArrays.
32
33 When glDrawArrays is called, it uses count sequential elements from
34 each enabled array to construct a sequence of geometric primitives,
35 beginning with element first. mode specifies what kind of primitives
36 are constructed and how the array elements construct those primitives.
37
38 Vertex attributes that are modified by glDrawArrays have an unspecified
39 value after glDrawArrays returns. Attributes that aren't modified
40 remain well defined.
41
43 GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY,
44 GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are available
45 only if the GL version is 3.2 or greater.
46
48 GL_INVALID_ENUM is generated if mode is not an accepted value.
49
50 GL_INVALID_VALUE is generated if count is negative.
51
52 GL_INVALID_OPERATION is generated if a non-zero buffer object name is
53 bound to an enabled array and the buffer object's data store is
54 currently mapped.
55
56 GL_INVALID_OPERATION is generated if a geometry shader is active and
57 mode is incompatible with the input primitive type of the geometry
58 shader in the currently installed program object.
