Bases: RenderAttrib

Specifies how polygons are to be drawn.

enum Mode
enumerator M_none = 0

No adjustments are made to normals.

enumerator M_rescale = 1

Normals are counterscaled by the transform’s uniform scale, if supported by the graphics API.

enumerator M_normalize = 2

Normals are scaled to unit length; potentially expensive.

enumerator M_auto = 3

Normals are counterscaled in the presence of a uniform scale transform, or normalized in the presence of a non-uniform scale transform.

static int get_class_slot(void)
static TypeHandle get_class_type(void)
Mode get_mode(void) const

Returns the render mode.

static ConstPointerTo<RenderAttrib> make(RescaleNormalAttrib::Mode mode)

Constructs a new RescaleNormalAttrib object that specifies whether to rescale normals to compensate for transform scales or incorrectly defined normals.

ConstPointerTo<RenderAttrib> make_default(void)

Constructs a RescaleNormalAttrib object that’s suitable for putting at the top of a scene graph. This will contain whatever attrib was suggested by the user’s rescale-normals Config variable.
