Syntax
[C/C++:]
void gSetFacetMaterialProps(int face, int amb, int diff, int spec, int emit, float shine, float trans);
[F90:]
subroutine gSetFacetMaterialProps(face, amb, diff, spec, emit, shine, trans)
integer, intent(in) :: face,amb,diff,spec,emit
real, intent(in) :: shine,trans
Arguments
face
Facet face
|
= GFRONT, |
Sets material properties for front face |
|
= GBACK, |
Sets material properties for back face |
amb
Ambient reflection colour
diff
Diffuse reflection colour
spec
Specular reflection colour
emit
Emission colour
shine
Specular concentration (shininess) as percentage
trans
Translucence (filtering) (0.0-1.0)
Description
The routine gSetFacetMaterialProps() sets the current facet material properties for either the front or back faces of all subsequently drawn facets (or objects). This overrides any material properties set using the material table using gSetMaterialIndex().
The parameters
amb,
diff,
spec and
emit are all integer values that may be indices into the GINO colour table or 24-bit RGB true colour values as returned by the function gTrueCol(). If any of the particular properties are not required the colour black (colour index 1 - GBLACK) should be used.
Translucence values less than 1.0 (opaque) are only utilized if surface blending is switched on by the gSetShadingMode() routine.
