Returns the shading model the system uses to draw filled polygons.
FORTRAN (libfgl.a)
Int32 getsm( )
INTEGER*4 GETSM
The getsm subroutine returns the shading model that the system uses to draw filled polygons. The returned value of this function indicates which shading model is now active.
Note: This subroutine cannot be used to add to a display list.
There are two possible return values:
| C | FORTRAN | Description |
| FLAT | FLAT | The system draws a filled polygon with a constant color across the entire surface of the polygon. |
| GOURAUD | GOURAU | The system draws a filled polygon with a color that varies as a linear interpolation of the colors at the polygon's vertices. |
This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.
| /usr/include/gl/gl.h | Contains C language constant and variable type definitions for GL. |
| /usr/include/gl/fgl.h | Contains FORTRAN constant and variable type definitions for GL. |
