Detailed Description
Indicates which faces should be culled based on their vertex ordering.
Definition at line 26 of file cullFaceAttrib.h.
Member Function Documentation
◆ write_datagram()
Writes the contents of this object to the datagram for shipping out to a Bam file.
Reimplemented from RenderAttrib.
Definition at line 232 of file cullFaceAttrib.cxx.
References Datagram::add_bool(), Datagram::add_int8(), and RenderAttrib::write_datagram().
Member Data Documentation
◆ get_actual_mode
|
inline |
Returns the actual culling mode, without considering the effects of the reverse flag.
See also get_effective_mode().
Definition at line 48 of file cullFaceAttrib.h.
◆ get_effective_mode
| CullFaceAttrib::Mode CullFaceAttrib::get_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.
Definition at line 50 of file cullFaceAttrib.h.
◆ get_reverse
|
inline |
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.
