I have a question related with an inconsistency in ES SC 1.0 specification. According to the spec., glLightModef API function is one of the supported API functions in a list of 101 API. glLightModelf specifies a single-valued lighting model parameter and normally, its accepted parameters are GL_LIGHT_MODEL_LOCAL_VIEWER and GL_LIGHT_MODEL_TWO_SIDE. However, according to ES SC 1.0 spec., both of these parameters are non-supported. So, there is no accepted parameter left to be used with glLightModelf. Is it correct? Will glLightModelf always generate GL_INVALID_ENUM error? Then, why it is in supported API list for ES SC?
Any help would be great! Thanks!
