unsigned short int | getMode () |
Returns the specified antialias mode. More... | |
unsigned short int | getModeQuality () |
Returns the specified antialias mode, with the type bits masked out. This therefore indicates only the requested quality settings: one of M_faster, M_better, M_dont_care, or zero (unspecified). More... | |
unsigned short int | getModeType () |
Returns the specified antialias mode, with the quality bits masked out. This therefore indicates only the requested type of antialiasing: M_none, M_auto, or some specific combination. More... | |
![]() | |
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. More... | |
const RenderAttrib | compose (const RenderAttrib other) |
Returns a new RenderAttrib object that represents the composition of this attrib with the other attrib. In most cases, this is the same as the other attrib; a compose b produces b. Some kinds of attributes, like a TextureTransform, for instance, might produce a new result: a compose b produces c. More... | |
const RenderAttrib | getAutoShaderAttrib (const RenderState state) |
Returns the variant of this RenderAttrib that's most relevant for associating with an auto-generated shader. This should be a new RenderAttrib of the same type as this one, with any superfluous data set to neutral. Only the parts of the attrib that contribute to the shader should be reflected in the returned attrib. The idea is to associate the auto-generated shader with the most neutral form of all states, to allow it to be shared across as many RenderState objects as possible. More... | |
size_t | getHash () |
Returns a suitable hash value for phash_map. More... | |
int | getSlot () |
const RenderAttrib | getUnique () |
Returns the pointer to the unique RenderAttrib in the cache that is equivalent to this one. This may be the same pointer as this object, or it may be a different pointer; but it will be an equivalent object, and it will be a shared pointer. This may be called from time to time to improve cache benefits. More... | |
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. In most cases, this is the same as the other attrib; !a compose b produces b. Some kinds of attributes, like a TextureTransform, for instance, might produce a new result: !a compose b produces c. More... | |
bool | lowerAttribCanOverride () |
Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact. More... | |

str | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string. Returns empty string on failure. More... | |
bool | encodeToBamStream (String data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. Returns true on success, false on failure. More... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. This counter is normally incremented automatically whenever the object is modified. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients. More... | |
![]() | |
TypeHandle | getType () |
Derived classes should override this function to return get_class_type(). More... | |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More... | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. More... | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. More... | |
![]() | |
int | getRefCount () |
Returns the current reference count. More... | |
ref () | |
Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More... | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More... | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More... | |
bool | unref () |
Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More... | |

static const RenderAttrib | make (unsigned short int mode) |
Constructs a new AntialiasAttrib object. More... | |
static const RenderAttrib | makeDefault () |
Returns a RenderAttrib that corresponds to whatever the standard default properties for render attributes of this type ought to be. More... | |
![]() | |
static int | garbageCollect () |
Performs a garbage-collection cycle. This is called automatically from RenderState::garbage_collect(); see that method for more information. More... | |
static TypeHandle | getClassType () |
static int | getNumAttribs () |
Returns the total number of unique RenderAttrib objects allocated in the world. This will go up and down during normal operations. More... | |
static | listAttribs (Ostream out) |
Lists all of the RenderAttribs in the cache to the output stream, one per line. This can be quite a lot of output if the cache is large, so be prepared. More... | |
static bool | validateAttribs () |
Ensures that the cache is still stored in sorted order. Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderAttrib objects). More... | |
![]() | |
static TypedWritableReferenceCount | decodeFromBamStream (str data, BamReader reader) |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on that string. Returns NULL on error. More... | |

unsigned short int getMode | ( | ) |
Returns the specified antialias mode.
unsigned short int getModeQuality | ( | ) |
Returns the specified antialias mode, with the type bits masked out. This therefore indicates only the requested quality settings: one of M_faster, M_better, M_dont_care, or zero (unspecified).
unsigned short int getModeType | ( | ) |
Returns the specified antialias mode, with the quality bits masked out. This therefore indicates only the requested type of antialiasing: M_none, M_auto, or some specific combination.
|
static |
Constructs a new AntialiasAttrib object.
The mode should be either M_none, M_auto, or a union of any or all of M_point, M_line, M_polygon, and M_multisample. Also, in addition to the above choices, it may include either of M_better of M_faster to specify a performance/quality tradeoff hint.
If M_none is specified, no antialiasing is performed.
If M_multisample is specified, it means to use the special framebuffer multisample bits for antialiasing, if it is available. If so, the M_point, M_line, and M_polygon modes are ignored. This advanced antialiasing mode is only available on certain graphics hardware. If it is not available, the M_multisample bit is ignored (and the other modes may be used instead, if specified).
M_point, M_line, and/or M_polygon specify per-primitive smoothing. When enabled, M_point and M_line may force transparency on. M_polygon requires a frame buffer that includes an alpha channel, and it works best if the primitives are sorted front-to-back.
If M_auto is specified, M_multisample is selected if it is available, otherwise M_polygon is selected, unless drawing lines or points, in which case M_line or M_point is selected (these two generally produce better results than M_multisample)
