NAME    [Toc]    [Back]

     tevbind -	selects	a texture environment

C SPECIFICATION    [Toc]    [Back]

     void tevbind(target, index)
     long target, index;

PARAMETERS    [Toc]    [Back]

     target   expects the texture resource to which the	environment definition
	      is to be bound.  There is	only one appropriate resource,
	      TV_ENV0.

     index    expects the name of the texture environment that is being	bound.
	      Name is the index	passed to tevdef when the environment was
	      defined.

DESCRIPTION    [Toc]    [Back]

     tevbind specifies which of	the previously defined texture mapping
     environments is to	be the current environment.  The texture environment
     defines how the results of	the texture function are applied.  Texture
     environments are defined using tevdef.

     By	default	environment definition 0 is bound to TV_ENV0.  Texture mapping
     is	enabled	when an	environment definition other than 0 is bound to
     TV_ENV0, and a texture definition other than 0 is bound to	TX_TEXTURE_0.
     (See texbind.)

NOTES    [Toc]    [Back]

     IRIS-4D G,	GT, and	GTX models, and	the Personal Iris, do not support
     texture mapping.  tevbind is ignored by these machines.  Iris Indy,
     Indigo Entry, and XL support texture mapping except for lines.  Use
     getgdesc to determine whether texture mapping is supported.

     tevbind cannot be used while mmode	is MSINGLE.
