◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getScale()

const LVecBase4 getScale ( )

Returns the scale to be applied to colors.

◆ hasAlphaScale()

bool hasAlphaScale ( )

Returns true if the ColorScaleAttrib has a non-identity scale in the alpha component (ignoring RGB), or false otherwise.

◆ hasRgbScale()

bool hasRgbScale ( )

Returns true if the ColorScaleAttrib has a non-identity scale in the RGB components (ignoring alpha), or false otherwise.

◆ hasScale()

bool hasScale ( )

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).

◆ isIdentity()

bool isIdentity ( )

Returns true if the ColorScaleAttrib is an identity attrib, false if it is either an off attrib or it has a scale.

◆ isOff()

bool isOff ( )

Returns true if the ColorScaleAttrib will ignore any color scales inherited from above, false otherwise.

This is not the same thing as !has_scale(); a ColorScaleAttrib may have the "off" flag set and also have another scale specified.

◆ make()

static const RenderAttrib make ( const LVecBase4  scale)
static

Constructs a new ColorScaleAttrib object that indicates geometry should be scaled by the indicated factor.

◆ makeDefault()

static const RenderAttrib makeDefault ( )
static

Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.

◆ makeIdentity()

static const RenderAttrib makeIdentity ( )
static

Constructs an identity scale attrib.

◆ makeOff()

static const RenderAttrib makeOff ( )
static

Constructs a new ColorScaleAttrib object that ignores any ColorScaleAttrib inherited from above.

You may also specify an additional color scale to apply to geometry below (using set_scale()).

◆ setScale()

const RenderAttrib setScale ( const LVecBase4  scale)

Returns a new ColorScaleAttrib, just like this one, but with the scale changed to the indicated value.
