GLCOLORMATERIAL(3G) GLCOLORMATERIAL(3G)NAMEglColorMaterial - cause a material color to track the current colorC SPECIFICATIONvoid glColorMaterial( GLenum face, GLenum mode )PARAMETERSface 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.DESCRIPTIONglColorMaterial 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.NOTESglColorMaterial makes it possible to change a subset of material parameters 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 inde- terminate. 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.ERRORSGL_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 GETSglIsEnabled with argument GL_COLOR_MATERIAL glGet with argument GL_COLOR_MATERIAL_PARAMETER glGet with argument GL_COLOR_MATERIAL_FACESEE ALSOglColor, glColorPointer, glDrawArrays, glDrawElements, glDrawRangeElements, glEnable, glLight, glLightModel, glMaterial GLCOLORMATERIAL(3G)
