Chapter 7 G glGetMap glGetMap glGetMapdv, glGetMapfv, glGetMapiv: return evaluator parameters. C Specification void glGetMapdv( GLenum target, GLenum query, GLdouble *v) void glGet GLenum target, GLenum query, GLfloat *v) void glGetMapiv( GLenum target, GLenum query, GLint *v) Parameters target query v Specifies the symbolic name of a map. Accepted values are GL_MAP1_COLOR_4, GL_MAP1_INDEX, GL_MAP1_NORMAL, GL_MAP1_TEXTURE_COORD_1, GL_MAP1_TEXTURE_COORD_2, GL_MAP1_TEXTURE_COORD_3, GL_MAP1_TEXTURE_COORD_4, GL_MAP1_VERTEX_3, GL_MAP1_VERTEX_4, GL_MAP2_COLOR_4, GL_MAP2_INDEX, GL_MAP2_NORMAL, GL_MAP2_TEXTURE_COORD_1, GL_MAP2_TEXTURE_COORD_2, GL_MAP2_TEXTURE_COORD_3, GL_MAP2_TEXTURE_COORD_4, GL_MAP2_VERTEX_3, and GL_MAP2_VERTEX_4. Specifies which parameter to return. Symbolic names GL_COEFF, GL_ORDER, and GL_DOMAIN are accepted. Returns the requested data. Description glMap1 and glMap2 define evaluators. glGetMap returns evaluator parameters. target chooses a map, query selects a specific parameter, and v points to storage where the values will be returned. The acceptable values for the target parameter are described in the glMap1 and glMap2 reference pages. query can assume the following values: GL_COEFF v returns the control points for the evaluator function. One-dimensional evaluators return order control points, and two-dimensional evaluators return uorder times vorder control points. Each control point consists of one, two, three, or four integer, single-precision floating-point, or double-precision floating-point values, depending on 199
