to enable and -disable it, call _cmnd(Enable) and _cmnd(Disable). -.P -When one of the _cmnd(EvalCoord) commands is issued, -all currently enabled maps of the indicated dimension are evaluated. -Then, -for each enabled map, -it is as if the corresponding GL command had been issued with the -computed value. -That is, -if _const(MAP1_INDEX) or -_const(MAP2_INDEX) is enabled, -a _cmnd(Index) command is simulated. -If _const(MAP1_COLOR_4) or -_const(MAP2_COLOR_4) is enabled, -a _cmnd(Color) command is simulated. -If _const(MAP1_NORMAL) or _const(MAP2_NORMAL) is enabled, -a normal vector is produced, -and if any of -_const(MAP1_TEXTURE_COORD_1), -_const(MAP1_TEXTURE_COORD_2), -_const(MAP1_TEXTURE_COORD_3), -_const(MAP1_TEXTURE_COORD_4), -_const(MAP2_TEXTURE_COORD_1), -_const(MAP2_TEXTURE_COORD_2), -_const(MAP2_TEXTURE_COORD_3), or -_const(MAP2_TEXTURE_COORD_4) is enabled, then an appropriate _cmnd(TexCoord) command is simulated. -.P -For color, -color index, -normal, -and texture coordinates the GL uses evaluated values instead of current values for those evaluations -that are enabled, -and current values otherwise, -However, -the evaluated values do not update the current values. -Thus, if _cmnd(Vertex) commands are interspersed with _cmnd(EvalCoord) -commands, the color, -normal, -and texture coordinates associated with the _cmnd(Vertex) commands are not -affected by the values generated by the _cmnd(EvalCoord) commands, -but only by the most recent -_cmnd(Color), -_cmnd(Index), -_cmnd(Normal), and -_cmnd(TexCoord) commands. -.P -No commands are issued for maps that are not enabled. -If more than one texture evaluation is enabled for a particular dimension -(for example, _const(MAP2_TEXTURE_COORD_1) and -_const(MAP2_TEXTURE_COORD_2)), -then only the evaluation of the map that produces the larger -number of coordinates -(in this case, _const(MAP2_TEXTURE_COORD_2)) -is carried out. -_const(MAP1_VERTEX_4) overrides _const(MAP1_VERTEX_3), -and -_const(MAP2_VERTEX_4) overrides _const(MAP2_VERTEX_3), -in the same manner. -If neither a three- nor a four-component vertex map is enabled for the -specified dimension, -the _cmnd(EvalCoord) command is ignored. -.P -If you have enabled automatic normal generation, -by calling _cmnd(Enable) with argument _const(AUTO_NORMAL), -_cmnd(EvalCoord2) generates surface normals analytically, -regardless of the contents or enabling of the _const(MAP2_NORMAL) map. -Let -.sp -.ce -.EQ -bold m ~=~ {partial bold p} over {partial u} ~times~ - {partial bold p} over {partial v} -.EN -.ce 0 -.sp -.br -Then the generated normal $ bold n $ is -.br -.ce -$bold n ~=~ bold m over { || bold m || }$ -.ce 0 -.sp -.br -If automatic normal generation is disabled, -the corresponding normal map _const(MAP2_NORMAL), -if enabled, -is used to produce a normal. -If neither automatic normal generation nor a normal map is enabled, -no normal is generated for -_cmnd(EvalCoord2) commands. -.SH ASSOCIATED GETS -.nf -_cmnd(IsEnabled) with argument _const(MAP1_VERTEX_3) -.br -_cmnd(IsEnabled) with argument _const(MAP1_VERTEX_4) -.br -_cmnd(IsEnabled) with argument _const(MAP1_INDEX) -.br -_cmnd(IsEnabled) with argument _const(MAP1_COLOR_4) -.br -_cmnd(IsEnabled) with argument _const(MAP1_NORMAL) -.br -_cmnd(IsEnabled) with argument _const(MAP1_TEXTURE_COORD_1) -.br -_cmnd(IsEnabled) with argument _const(MAP1_TEXTURE_COORD_2) -.br -_cmnd(IsEnabled) with argument _const(MAP1_TEXTURE_COORD_3) -.br -_cmnd(IsEnabled) with argument _const(MAP1_TEXTURE_COORD_4) -.br -_cmnd(IsEnabled) with argument _const(MAP2_VERTEX_3) -.br -_cmnd(IsEnabled) with argument _const(MAP2_VERTEX_4) -.br -_cmnd(IsEnabled) with argument _const(MAP2_INDEX) -.br -_cmnd(IsEnabled) with argument _const(MAP2_COLOR_4) -.br -_cmnd(IsEnabled) with argument _const(MAP2_NORMAL) -.br -_cmnd(IsEnabled) with argument _const(MAP2_TEXTURE_COORD_1) -.br -_cmnd(IsEnabled) with argument _const(MAP2_TEXTURE_COORD_2) -.br -_cmnd(IsEnabled) with argument _const(MAP2_TEXTURE_COORD_3) -.br -_cmnd(IsEnabled) with argument _const(MAP2_TEXTURE_COORD_4) -.br -_cmnd(IsEnabled) with argument _const(AUTO_NORMAL) -.br -_cmnd(GetMap) -.SH SEE ALSO -_cmnd(Begin), -_cmnd(Color), -_cmnd(Enable), -_cmnd(EvalMesh), -_cmnd(EvalPoint), -_cmnd(Index), -_cmnd(Map1), -_cmnd(Map2), -_cmnd(MapGrid), -_cmnd(Normal), -_cmnd(TexCoord), -_cmnd(Vertex) |
