¶ Bases:
RenderAttrib
Applies a scale to colors in the scene graph and on vertices.

bool
has_alpha_scale
(void) const¶ Returns true if the
ColorScaleAttrib
has a non-identity scale in the alpha component (ignoring RGB), or false otherwise.
-
bool
has_rgb_scale
(void) const¶ Returns true if the
ColorScaleAttrib
has a non-identity scale in the RGB components (ignoring alpha), or false otherwise.
-
bool
has_scale
(void) const¶ Returns true if the
ColorScaleAttrib
has a non-identity scale, false otherwise (in which case it might be an off attrib or an identity attrib).
-
bool
is_identity
(void) const¶ Returns true if the
ColorScaleAttrib
is an identity attrib, false if it is either an off attrib or it has a scale.
-
bool
is_off
(void) const¶ Returns true if the
ColorScaleAttrib
will ignore any color scales inherited from above, false otherwise. This is not the same thing as !has_scale(); aColorScaleAttrib
may have the “off” flag set and also have another scale specified.
-
static ConstPointerTo<RenderAttrib>
make
(LVecBase4 const &scale)¶ Constructs a new
ColorScaleAttrib
object that indicates geometry should be scaled by the indicated factor.
-
static ConstPointerTo<RenderAttrib>
make_default
(void)¶ Returns a
RenderAttrib
that corresponds to whatever the standard default properties for render attributes of this type ought to be.
-
static ConstPointerTo<RenderAttrib>
make_identity
(void)¶ Constructs an identity scale attrib.
-
static ConstPointerTo<RenderAttrib>
make_off
(void)¶ Constructs a new
ColorScaleAttrib
object that ignores anyColorScaleAttrib
inherited from above. You may also specify an additional color scale to apply to geometry below (usingset_scale()
).
-
ConstPointerTo<RenderAttrib>
set_scale
(LVecBase4 const &scale) const¶ Returns a new
ColorScaleAttrib
, just like this one, but with the scale changed to the indicated value.
