void GLAPIENTRY glInterleavedArrays( GLenum format,
GLsizei strid )
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.
strid Specifies the offset in bytes between each aggregate array ele‐
ment.
DESCRIPTION
glInterleavedArrays lets you specify and enable individual color, nor‐
mal, texture and vertex arrays whose elements are part of a larger ag‐
gregate array element. For some implementations, this is more efficient
than specifying the arrays separately.
If strid is 0, the aggregate elements are stored consecutively. Other‐
wise, strid bytes occur between the beginning of one aggregate array el‐
ement and the beginning of the next aggregate array element.
format serves as a ``key'' describing the extraction of individual ar‐
rays from the aggregate array. If format contains a T, then texture co‐
ordinates are extracted from the interleaved array. If C is present,
color values are extracted. If N is present, normal coordinates are ex‐
tracted. Vertex coordinates are always extracted.
The digits 2, 3, and 4 denote how many values are extracted. F indi‐
cates 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 unde‐
fined.
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.
