Channels
The pipeline is divided into the following channels:
#define	TOPO_CHANNEL   (1<<0)
	The topology channel - the face or polygon structures.
#define	GEOM_CHANNEL   (1<<1)
	The vertices of the object.
#define	TEXMAP_CHANNEL   (1<<2)
	The texture vertices and procedural mappings.
#define	MTL_CHANNEL   (1<<3)
	This is no longer used.
#define	SELECT_CHANNEL   (1<<4)
	The sub-object selection channel.
#define	SUBSEL_TYPE_CHANNEL   (1<<5)
	The current level of selection.
#define	DISP_ATTRIB_CHANNEL   (1<<6)
	The miscellaneous bits controlling the item's display.
#define	VERTCOLOR_CHANNEL   (1<<7)
	The color per vertex channel.
#define	GFX_DATA_CHANNEL   (1<<8)
	The used internally by 3ds Max for stripping.
#define	DISP_APPROX_CHANNEL   (1<<9)
	Displacement approximation.
#define	EXTENSION_CHANNEL   (1<<13)
	The channel used by extension channel objects.
#define	TM_CHANNEL   (1<<10)
	The ObjectState TM that flows down the pipeline.
#define	EDGEVISIBLITY_CHANNEL   (1<<11)
	For internal use.
#define	DONT_RECREATE_TRISTRIP_CHANNEL   (1<<12)
	For internal use.
#define	GLOBMTL_CHANNEL   (1<<31)
	This is no longer used.
#define	OBJ_CHANNELS   (TOPO_CHANNEL|GEOM_CHANNEL|SELECT_CHANNEL|TEXMAP_CHANNEL|MTL_CHANNEL|SUBSEL_TYPE_CHANNEL|DISP_ATTRIB_CHANNEL|VERTCOLOR_CHANNEL|GFX_DATA_CHANNEL|DISP_APPROX_CHANNEL|EXTENSION_CHANNEL)
#define	ALL_CHANNELS   (OBJ_CHANNELS|TM_CHANNEL|GLOBMTL_CHANNEL)
Object Channel Indices
The following are the indices that may be used for the object channels. These values are used in the methods Object::UpdateValidity(), Object::SetChannelValidity() and Object::ChannelValidity().
#define	TOPO_CHAN_NUM   0
	The topology channel number.
#define	GEOM_CHAN_NUM   1
	The geometry channel number.
#define	TEXMAP_CHAN_NUM   2
	The texture vertices and procedural mappings channels number.
#define	MTL_CHAN_NUM   3
	This is no longer used.
#define	SELECT_CHAN_NUM   4
	The sub-object selection channel number.
#define	SUBSEL_TYPE_CHAN_NUM   5
	This is the current level of selection number.
#define	DISP_ATTRIB_CHAN_NUM   6
	The display channel number.
#define	VERT_COLOR_CHAN_NUM   7
	The vertex colors number. This is also used for the second mapping channel.
#define	GFX_DATA_CHAN_NUM   8
	The stripping, edge list, etc. channel number.
#define	DISP_APPROX_CHAN_NUM   9
	The displacement approximation channel number.
#define	EXTENSION_CHAN_NUM   10
	The extension object channel number.
