tevbin(3G)

NAME
     tevbin -  selects a texture environment

FORTRAN SPECIFICATION
     subroutine tevbin(target, index)
     integer*4 target, index

PARAMETERS
     target   expects the texture resource to which the environment definition
              is to be bound.  There is only one appropriate resource, TVENV0.

     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
     tevbin 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 TVENV0.  Texture mapping
     is enabled when an environment definition other than 0 is bound to
     TVENV0, and a texture definition other than 0 is bound to TXTEXT.  (See
     texbin.)

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

     tevbin cannot be used while mmode is MSINGL.
