fglGetDetailTexFuncSGIS(3G)

NAME
     fglGetDetailTexFuncSGIS - get detail texture scaling function


FORTRAN SPECIFICATION
     SUBROUTINE fglGetDetailTexFuncSGIS( INTEGER*4 target,
                                         CHARACTER*8 points )


PARAMETERS
     target  The texture whose detail texture scaling function is to be
             retrieved.  Must be GL_TEXTURE_2D.

     points  A pointer to a floating-point array which receives the retrieved
             detail texture function.  Each pair of elements in the array
             receives an LOD (level-of-detail) value and a scaling function
             value.

DESCRIPTION
     fglGetDetailTexFuncSGIS retrieves the detail texture scaling function
     samples specified by fglDetailTexFuncSGIS.  See fglDetailTexFuncSGIS for
     a discussion of detail texturing.

NOTES
     The number of elements in points may be queried by calling
     fglGetTexParameter with target set to GL_TEXTURE_2D and pname set to
     GL_DETAIL_TEXTURE_FUNC_POINTS_SGIS.

ERRORS
     GL_INVALID_ENUM is generated if target is not an allowable value.

     GL_INVALID_OPERATION is generated if fglGetDetailTexFuncSGIS is executed
     between the execution of fglBegin and the corresponding execution of
     fglEnd.


MACHINE DEPENDENCIES
     On RealityEngine, RealityEngine2, and VTX systems detail texturing may
     not be used when rendering to pixmaps.

     RealityEngine, RealityEngine2, and VTX systems do not support
     fglGetDetailTexFuncSGIS correctly.
