Sets a property for the display of trimmed NURBS surfaces.
FORTRAN (libfgl.a)
void setnurbsproperty(Int32 Property, Float32 Value)
SUBROUTINE SETNUR(property, value) INTEGER*4 property REAL value
The setnurbsproperty subroutine sets a property for the display of a trimmed Non-Uniform Rational B-Spline (NURBS) surfaces. The display of NURBS surfaces can be controlled in different ways. The following is a list of the display properties that can be affected.
| C | FORTRAN | Description |
| N_ERRORCHECKING | NERROR | If value is 1.0, some error checking is enabled. If error checking is disabled, the system runs slightly faster. The default value is 0.0. |
| N_PIXEL_TOLERANCE | NPIXEL | The value is the maximum length, in pixels, of edges of polygons on the screen used to render trimmed NURBS surfaces. The default value is 50.0 pixels. |
| property | Specifies the name of the property to be set. |
| value | Specifies the value to which the named property is to be set. |
