.SH NAME
EZ_LightModelf, EZ_LightModelfv \- set lighting model parameters

.SH SYNOPSIS
.nf
.B #include <EZ.h>
.sp
.BI "void EZ_LightModelf(int "attr ", float " values )

.BI "void EZ_LightModelfv(int " attr ", float *" pvalues )

.SH ARGUMENTS
.sp
\fIattr\fR Specifies which attribute is being updated.
Must be one of EZ_LIGHT_MODEL_LOCAL_VIEWER, EZ_LIGHT_MODEL_AMBIENT
or EZ_LIGHT_MODEL_TWO_SIDE.
.sp
\fIvalues\fR Specifies the values for the specified \fIattr\fR.
.sp
\fIpvalues\fR Specifies the values for the specified \fIattr\fR in
an array of floats.

.SH DESCRIPTION
\fBEZ_LightModelf/EZ_LightModelfv\fR sets lighting model parameters.
.sp
If \fIattr\fR is EZ_LIGHT_MODEL_AMBIENT, \fIvalues\fR should consist
of 4 floats and \fIpvalues\fR should be an array of 4 floats, with
each in interval [0.0, 1.0].
.sp
If \fIattr\fR is EZ_LIGHT_MODEL_LOCAL_VIEWER or EZ_LIGHT_MODEL_TWO_SIDE,
\fIvalues\fR should be a single float point number. If \fIvalues\fR is
nonzero, it enables the corresponding capability.
