NAME
glInterleavedArrays - simultaneously specify and enable several
interleaved arrays
C SPECIFICATION
void glInterleavedArrays(GLenum format, GLsizei stride,
const GLvoid * pointer);
PARAMETERS
format
Specifies the type of array to enable. Symbolic constants GL_V2F,
GL_V3F, GL_C4UB_V2F, GL_C4UB_V3F, GL_C3F_V3F, GL_N3F_V3F,
GL_C4F_N3F_V3F, GL_T2F_V3F, GL_T4F_V4F, GL_T2F_C4UB_V3F,
GL_T2F_C3F_V3F, GL_T2F_N3F_V3F, GL_T2F_C4F_N3F_V3F, and
GL_T4F_C4F_N3F_V4F are accepted.
stride
Specifies the offset in bytes between each aggregate array element.
DESCRIPTION
glInterleavedArrays lets you specify and enable individual color,
normal, texture and vertex arrays whose elements are part of a larger
aggregate array element. For some implementations, this is more
efficient than specifying the arrays separately.
If stride is 0, the aggregate elements are stored consecutively.
Otherwise, stride bytes occur between the beginning of one aggregate
array element and the beginning of the next aggregate array element.
format serves as a ``key'' describing the extraction of individual
arrays from the aggregate array. If format contains a T, then texture
coordinates are extracted from the interleaved array. If C is present,
color values are extracted. If N is present, normal coordinates are
extracted. Vertex coordinates are always extracted.
The digits 2, 3, and 4 denote how many values are extracted. F
indicates that values are extracted as floating-point values. Colors
may also be extracted as 4 unsigned bytes if 4UB follows the C. If a
color is extracted as 4 unsigned bytes, the vertex array element which
follows is located at the first possible floating-point aligned
address.
NOTES
glInterleavedArrays is available only if the GL version is 1.1 or
greater.
If glInterleavedArrays is called while compiling a display list, it is
not compiled into the list, and it is executed immediately.
Execution of glInterleavedArrays is not allowed between the execution
of glBegin() and the corresponding execution of glEnd(), but an error
may or may not be generated. If no error is generated, the operation is
undefined.
glInterleavedArrays is typically implemented on the client side.
Vertex array parameters are client-side state and are therefore not
saved or restored by glPushAttrib() and glPopAttrib(). Use
glPushClientAttrib() and glPopClientAttrib() instead.
For OpenGL versions 1.3 and greater, or when the ARB_multitexture
extension is supported, glInterleavedArrays only updates the texture
coordinate array for the client active texture unit. The texture
coordinate state for other client texture units is not updated,
regardless of whether the client texture unit is enabled or not.
Secondary color values are not supported in interleaved vertex array
formats.
ERRORS
GL_INVALID_ENUM is generated if format is not an accepted value.
GL_INVALID_VALUE is generated if stride is negative.
