-lines, -bitmaps, -and all polygons -(when two-sided lighting is disabled), -or just front-facing polygons -(when two-sided lighting is enabled). -The other set, -\f2back-facing\fP, -is used to shade back-facing polygons only when two-sided lighting is enabled. -Refer to the _cmnd(LightModel) reference page for details concerning one- and -two-sided lighting calculations. -.P -_cmnd takes three arguments. -The first, -_param1, -specifies whether the -_const(FRONT) materials, the -_const(BACK) materials, or both -_const(FRONT_AND_BACK) materials will be modified. -The second, -_param2, -specifies which of several parameters in one or both sets will be modified. -The third, -_param3, -specifies what value or values will be assigned to the specified parameter. -.P -Material parameters are used in the lighting equation that is optionally -applied to each vertex. -The equation is discussed in the _cmnd(LightModel) reference page. -The parameters that can be specified using _cmnd, -and their interpretations by the lighting equation, are as follows: -.TP 20 -_const(AMBIENT) -_param3 contains four integer or floating-point values that specify -the ambient RGBA reflectance of the material. -Integer values are mapped linearly such that the most positive representable -value maps to 1.0, -and the most negative representable value maps to \-1.0. -Floating-point values are mapped directly. -Neither integer nor floating-point values are clamped. -The initial ambient reflectance for both front- and back-facing materials -is (0.2, 0.2, 0.2, 1.0). -.TP -_const(DIFFUSE) -_param3 contains four integer or floating-point values that specify -the diffuse RGBA reflectance of the material. -Integer values are mapped linearly such that the most positive representable -value maps to 1.0, -and the most negative representable value maps to \-1.0. -Floating-point values are mapped directly. -Neither integer nor floating-point values are clamped. -The initial diffuse reflectance for both front- and back-facing materials -is (0.8, 0.8, 0.8, 1.0). -.TP -_const(SPECULAR) -_param3 contains four integer or floating-point values that specify -the specular RGBA reflectance of the material. -Integer values are mapped linearly such that the most positive representable -value maps to 1.0, -and the most negative representable value maps to \-1.0. -Floating-point values are mapped directly. -Neither integer nor floating-point values are clamped. -The initial specular reflectance for both front- and back-facing materials -is (0, 0, 0, 1). -.TP -_const(EMISSION) -_param3 contains four integer or floating-point values that specify -the RGBA emitted light intensity of the material. -Integer values are mapped linearly such that the most positive representable -value maps to 1.0, -and the most negative representable value maps to \-1.0. -Floating-point values are mapped directly. -Neither integer nor floating-point values are clamped. -The initial emission intensity for both front- and back-facing materials -is (0, 0, 0, 1). -.TP -_const(SHININESS) -_param3 is a single integer or floating-point value that specifies -the RGBA specular exponent of the material. -Integer and floating-point values are mapped directly. -Only values in the range [0,128] are accepted. -The initial specular exponent for both front- and back-facing materials -is 0. -.TP -_const(AMBIENT_AND_DIFFUSE) -Equivalent to calling _cmnd twice with the same parameter values, -once with _const(AMBIENT) and once with _const(DIFFUSE). -.TP -_const(COLOR_INDEXES) -_param3 contains three integer or floating-point values specifying -the color indices for ambient, -diffuse, -and specular lighting. -These three values, -and _const(SHININESS), -are the only material values used by the color index mode lighting equation. -Refer to the _cmnd(LightModel) reference page for a discussion -of color index lighting. -.SH NOTES -The material parameters can be updated at any time. -In particular, -_cmnd can be called between a call to _cmnd(Begin) and the corresponding -call to _cmnd(End). -If only a single material parameter is to be changed per vertex, -however, -_cmnd(ColorMaterial) is preferred over _cmnd -(see _cmnd(ColorMaterial)). -.P -While the ambient, diffuse, specular and emission material parameters -all have alpha components, only the diffuse alpha component is used in -the lighting computation. -.SH ERRORS -_const(INVALID_ENUM) is generated if either _param1 or _param2 is not -an accepted value. -.P -_const(INVALID_VALUE) is generated if a specular exponent outside the range -[0,128] is specified. -.SH ASSOCIATED GETS -_cmnd(GetMaterial) -.SH SEE ALSO -_cmnd(ColorMaterial), -_cmnd(Light), -_cmnd(LightModel) |
