Public Member Functions | |
int | getOutputs () |
Returns the AuxBitplaneAttrib output bits. | |
![]() | |
int | compareTo (const RenderAttrib other) |
Provides an arbitrary ordering among all unique RenderAttribs, so we can store the essentially different ones in a big set and throw away the rest. | |
const RenderAttrib | compose (const RenderAttrib other) |
Returns a new RenderAttrib object that represents the composition of this attrib with the other attrib. | |
int | getHash () |
Returns a suitable hash value for phash_map. | |
int | getSlot () |
const RenderAttrib | getUnique () |
Returns the pointer to the unique RenderAttrib in the cache that is equivalent to this one. | |
const RenderAttrib | invertCompose (const RenderAttrib other) |
Returns a new RenderAttrib object that represents the composition of the inverse of this attrib with the other attrib. | |
bool | lowerAttribCanOverride () |
Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact. | |
output (Ostream out) | |
write (Ostream out, int indent_level) | |
![]() | |
object | __reduce__ () |
object | __reduce_persist__ (object pickler) |
VectorUchar | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. | |
bool | encodeToBamStream (VectorUchar data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. | |
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. | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. | |
![]() | |
TypeHandle | getType () |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. | |
![]() | |
int | getRefCount () |
Returns the current reference count. | |
ref () | |
Explicitly increments the reference count. | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. | |
bool | unref () |
Explicitly decrements the reference count. | |

Ensures that the cache is still stored in sorted order. | |

Modern frame buffers can have 'aux' bitplanes, which are additional bitplanes above and beyond the standard depth and color.
This attrib controls what gets rendered into those additional bitplanes. It can also affect what goes into the alpha channel of the primary color buffer.
ABO_glow: copy the glow map into the alpha channel of the primary frame buffer. If there is no glow map, set it to zero. Caveat: it is not possible to write glow or depth values to the framebuffer alpha channel at the same time as using alpha blending or alpha testing. Any attempt to use transparency, blending, or alpha testing will cause this flag to be overridden.
ABO_aux_normal: put the camera-space normal into the into the R,G components of the first auxiliary bitplane.
ABO_aux_modelz: put the clip-space Z coordinate of the center of the model (after perspective divide) into the B channel of the first auxiliary bitplane.
ABO_aux_glow: put a copy of the glow map into the alpha channel of the first auxiliary bitplane. If there is no glow map, set it to zero.
AuxBitplaneAttrib is relevant only when shader generation is enabled. Otherwise, it has no effect.
