Returns the pointer to the unique RenderAttrib in the cache that is equivalent to this one. More... | |

fillin (DatagramIterator scan, BamReader manager) | |
This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. More... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More... | |

enum Mode |
CullFaceAttrib::Mode getActualMode | ( | ) |
Returns the actual culling mode, without considering the effects of the reverse flag.
See also get_effective_mode().

static |
|
static |
CullFaceAttrib::Mode getEffectiveMode | ( | ) |
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.
bool getReverse | ( | ) |
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 make_reverse(), which defines a CullFaceAttrib that reverses whatever the sense of culling would have been.
|
static |
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 |
Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be.
|
static |
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.
int class_slot |
CullFaceAttrib::Mode effective_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.
CullFaceAttrib::Mode mode |
Returns the actual culling mode, without considering the effects of the reverse flag.
See also get_effective_mode().
bool reverse |
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 make_reverse(), which defines a CullFaceAttrib that reverses whatever the sense of culling would have been.
