The initial value is _const(MODULATE). +.TP +_const(TEXTURE_ENV_COLOR) +_param3 returns four integer or floating-point values that are the +texture environment color. +Integer values, +when requested, +are linearly mapped from the internal floating-point representation +such that 1.0 maps to the most positive representable integer, +and \-1.0 maps to the most negative representable integer. The initial +value is (0, 0, 0, 0). +.SH NOTES +If an error is generated, +no change is made to the contents of _param3. +.P +When the _arbstring(multitexture) extension is supported, _cmnd returns +the texture environment parameters for the active texture unit. +.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(ActiveTextureARB), +_cmnd(TexEnv) |
