EZ_DefineMaterial(3)		EZWGL Functions		  EZ_DefineMaterial(3)

NAME
       EZ_DefineMaterial, EZ_BindMaterial - define material parameters

SYNOPSIS
       #include <EZ.h>

       EZ_Material *EZ_DefineMaterial(float *parameters)
       void EZ_BindMaterial(int face, EZ_Material *material)

ARGUMENTS
       parameters  Specifies material properties.

       face Specifies a face, either EZ_FRONT or EZ_BACK or EZ_FRONT_AND_BACK.

       material Specifies a pre-defined material.

DESCRIPTION
       EZ_DefineMaterial defines a material based on the specified parameters.
       The defined material can later be bind to one of the two current	 mate‐
       rials.

       parameters specifies an array of floating point symbols and values that
       defines the material properties.	 parameters must contain a sequence of
       lighting	 symbols,  each followed by the appropriate number of floating
       point values.  The last symbol must be EZ_NULL_F, which is  itself  not
       followed by any values.

       The symbols are:

	  EZ_EMISSION_F specifies the emisive color of the material, must fol‐
	  lowed by 4 floats in the range [0.0, 1.0] that specify the intensity
	  of the RGBA components of the color.

	  EZ_AMBIENT_F	specifies the ambient color of the material, must fol‐
	  lowed by 4 floats in the range [0.0, 1.0] that specify the intensity
	  of the RGBA components of the color.

	  EZ_DIFFUSE_F	specifies the diffuse color of the material, must fol‐
	  lowed by 4 floats in the range [0.0, 1.0] that specify the intensity
	  of the RGBA components of the color.

	  EZ_SPECULAR_F	 specifies  the	 specular  color of the material, must
	  followed by 4 floats in the range [0.0, 1.0] that specify the inten‐
	  sity of the RGBA components of the color.

	  EZ_SHININESS_F  specifies  the  shininess of the material, must fol‐
	  lowed by a non-negative floating point  number  that	specifies  the
	  shininess exponent.

	  EZ_COLOR_INDICES_F  specifies the indices that to be used for light‐
	  ing calculations in index mode. Must be  followed  by	 three	floats
	  that specify the ambient, diffuse and specular color indices.

       EZ_BindMaterial	binds the specified pre-defined material to the speci‐
       fied current material.
