CullFaceAttrib¶

from panda3d.core import CullFaceAttrib

class CullFaceAttrib¶

Bases: RenderAttrib

Indicates which faces should be culled based on their vertex ordering.

Inheritance diagram

enum Mode

enumerator M_cull_none = 0¶: Cull no polygons

enumerator M_cull_clockwise = 1¶: Cull clockwise-oriented polygons

enumerator M_cull_counter_clockwise = 2¶: Cull counter-clockwise-oriented polygons

enumerator M_cull_unchanged = 3¶: Do not change existing cull behavior

property class_slot → int ¶

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().

static getClassSlot() → int ¶

static 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 a CullFaceAttrib 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 other CullFaceAttrib objects in the scene graph. M_cull_clockwise will be treated as M_cull_counter_clockwise, and vice-versa. M_cull_none is unchanged.

property mode → Mode¶: Returns the actual culling mode, without considering the effects of the reverse flag. See also getEffectiveMode().

property reverse → 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 a CullFaceAttrib that reverses whatever the sense of culling would have been.
