Six parameters are defined: +.TP 22 +_const(AMBIENT) +_param3 returns four integer or floating-point values representing the +ambient reflectance of the material. +Integer values, +when requested, +are linearly mapped from the internal floating-point representation +such that 1.0 maps to the most positive representable integer value, +and \-1.0 maps to the most negative representable integer value. +If the internal value is outside the range [\-1, 1], +the corresponding integer return value is undefined. The initial value is +(0.2, 0.2, 0.2, 1.0) +.TP +_const(DIFFUSE) +_param3 returns four integer or floating-point values representing the +diffuse reflectance of the material. +Integer values, +when requested, +are linearly mapped from the internal floating-point representation +such that 1.0 maps to the most positive representable integer value, +and \-1.0 maps to the most negative representable integer value. +If the internal value is outside the range [\-1, 1], +the corresponding integer return value is undefined. The initial value is +(0.8, 0.8, 0.8, 1.0). +.TP +_const(SPECULAR) +_param3 returns four integer or floating-point values representing the +specular reflectance of the material. +Integer values, +when requested, +are linearly mapped from the internal floating-point representation +such that 1.0 maps to the most positive representable integer value, +and \-1.0 maps to the most negative representable integer value. +If the internal value is outside the range [\-1, 1], +the corresponding integer return value is undefined. The initial value is +(0, 0, 0, 1). +.TP +_const(EMISSION) +_param3 returns four integer or floating-point values representing the +emitted light intensity of the material. +Integer values, +when requested, +are linearly mapped from the internal floating-point representation +such that 1.0 maps to the most positive representable integer value, +and \-1.0 maps to the most negative representable integer value. +If the internal value is outside the range [\-1, 1.0], +the corresponding integer return value is undefined. The initial value is +(0, 0, 0, 1). +.TP +_const(SHININESS) +_param3 returns one integer or floating-point value representing the +specular exponent of the material. +Integer values, +when requested, +are computed by rounding the internal floating-point value to the +nearest integer value. The initial value is 0. +.TP +_const(COLOR_INDEXES) +_param3 returns three integer or floating-point values representing the +ambient, diffuse, and specular indices of the material. +These indices are used only for color index lighting. +(All the other parameters are used only for RGBA lighting.) +Integer values, +when requested, +are computed by rounding the internal floating-point values to the +nearest integer values. +.SH NOTES +If an error is generated, +no change is made to the contents of _param3. +.SH ERRORS +_const(INVALID_ENUM) is generated if _param1 or _param2 is not an +accepted value. +.P +_const(INVALID_OPERATION) is generated if _cmnd +is executed between the execution of _cmnd(Begin) +and the corresponding execution of _cmnd(End). +.SH SEE ALSO +_cmnd(Material) |
