property
effective_mode
→ Mode¶ Returns the effective culling mode. This is the same as the actual culling mode, unless the reverse flag is set, which swaps CW for CCW and vice- versa. Also, M_cull_unchanged is mapped to M_cull_none.
-
getActualMode
() → Mode¶ Returns the actual culling mode, without considering the effects of the reverse flag. See also
getEffectiveMode()
.

getClassType
() → TypeHandle¶
-
getEffectiveMode
() → Mode¶ Returns the effective culling mode. This is the same as the actual culling mode, unless the reverse flag is set, which swaps CW for CCW and vice- versa. Also, M_cull_unchanged is mapped to M_cull_none.
-
getReverse
() → bool¶ Returns the ‘reverse’ flag. If this is true, the actual cull direction (clockwise vs. counterclockwise) is the reverse of what is specified here. This allows support for
makeReverse()
, which defines aCullFaceAttrib
that reverses whatever the sense of culling would have been.
-
static
make
(mode: Mode) → RenderAttrib¶ Constructs a new
CullFaceAttrib
object that specifies how to cull geometry. By Panda convention, vertices are ordered counterclockwise when seen from the front, so the M_cull_clockwise will cull backfacing polygons.M_cull_unchanged is an identity attrib; if this is applied to vertices without any other intervening attrib, it is the same as applying the default attrib.
-
static
makeDefault
() → RenderAttrib¶ Returns a
RenderAttrib
that corresponds to whatever the standard default properties for render attributes of this type ought to be.
-
static
makeReverse
() → RenderAttrib¶ Constructs a new
CullFaceAttrib
object that reverses the effects of any otherCullFaceAttrib
objects in the scene graph. M_cull_clockwise will be treated as M_cull_counter_clockwise, and vice-versa. M_cull_none is unchanged.
