GLCOLORMATERIAL(3G)					   GLCOLORMATERIAL(3G)

NAME
       glColorMaterial - cause a material color to track the current color

C SPECIFICATION
       void glColorMaterial( GLenum face,
			     GLenum mode )

PARAMETERS
       face  Specifies	whether	 front,	 back, or both front and back material
	     parameters should track the current color.	 Accepted  values  are
	     GL_FRONT,	GL_BACK,  and GL_FRONT_AND_BACK.  The initial value is
	     GL_FRONT_AND_BACK.

       mode  Specifies which of several material parameters track the  current
	     color.   Accepted values are GL_EMISSION, GL_AMBIENT, GL_DIFFUSE,
	     GL_SPECULAR, and GL_AMBIENT_AND_DIFFUSE.  The  initial  value  is
	     GL_AMBIENT_AND_DIFFUSE.

DESCRIPTION
       glColorMaterial	specifies  which material parameters track the current
       color.  When GL_COLOR_MATERIAL is enabled, the  material	 parameter  or
       parameters specified by mode, of the material or materials specified by
       face, track the current color at all times.

       To enable and disable GL_COLOR_MATERIAL, call  glEnable	and  glDisable
       with  argument  GL_COLOR_MATERIAL.  GL_COLOR_MATERIAL is initially dis‐
       abled.

NOTES
       glColorMaterial makes it possible to change a subset of material param‐
       eters  for  each vertex using only the glColor command, without calling
       glMaterial.  If only such a subset of parameters is to be specified for
       each   vertex,	calling	  glColorMaterial  is  preferable  to  calling
       glMaterial.

       Call glColorMaterial before enabling GL_COLOR_MATERIAL.

       Calling glDrawElements, glDrawArrays, or glDrawRangeElements may	 leave
       the  current  color  indeterminate,  if the color array is enabled.  If
       glColorMaterial is enabled while the current  color  is	indeterminate,
       the lighting material state specified by face and mode is also indeter‐
       minate.

       If the GL version is 1.1 or greater, and GL_COLOR_MATERIAL is  enabled,
       evaluated  color	 values affect the results of the lighting equation as
       if the current color were being modified, but no change is made to  the
       tracking lighting parameter of the current color.

ERRORS
       GL_INVALID_ENUM is generated if face or mode is not an accepted value.

       GL_INVALID_OPERATION   is  generated  if	 glColorMaterial  is  executed
       between the execution of glBegin and  the  corresponding	 execution  of
       glEnd.

ASSOCIATED GETS
       glIsEnabled with argument GL_COLOR_MATERIAL
       glGet with argument GL_COLOR_MATERIAL_PARAMETER
       glGet with argument GL_COLOR_MATERIAL_FACE
