Simultaneously specifies and enables several interleaved arrays.
OpenGL C bindings library: libGL.a
void glInterleavedArrays(GLenum format, GLsizei stride, const GLvoid *pointer)
|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, or GL_T4F_C4F_N3F_V4F are accepted.|
|stride||Specifies the offset in bytes between each aggregate array element.|
The glInterleavedArrays subroutine 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 seperately.
If stride is zero then the aggregate element are stored consecutively, otherwise stride bytes occur between aggregate array elements.
The format enumerant 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.
The glInterleavedArrays subroutine 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 glBegin and the corresponding glEnd, but an error may or may not be generated. If an error is not generated, the operation is undefined.
The glInterleavedArrays subroutine is typically implemented on the client side with no protocol.
Since the vertex array parameters are client side state, they are not saved or restored by glPushAttrib and glPopAttrib. Use glPushClientAttrib and glPopClientAttrib instead.
GL_INVALID_ENUM is generated if format is not an accepted value.
GL_INVALID_VALUE is generated if stride is negative.
