tevbin(3G)tevbin(3G)NAMEtevbin - 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.
DESCRIPTIONtevbin 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.
