Public Member Functions | |
__init__ () | |
setProperties (int properties) | |
Sets the set of properties that determines which polygons are allowed to be grouped together into a single polyset. More... | |
![]() | |
bool | collapseGroup (const EggGroup group, int bin_number) |
May be overridden in derived classes to specify whether a particular group node, apparently redundant, may be safely collapsed out. More... | |
str | getBinName (int bin_number, const EggNode child) |
May be overridden in derived classes to define a name for each new bin, based on its bin number, and a sample child. More... | |
int | getBinNumber (const EggNode node) |
EggBin | makeBin (int bin_number, const EggNode child, EggGroup collapse_from) |
May be overridden in derived classes to construct a new EggBin object (or some derived class, if needed), and preload some initial data into as required. More... | |
int | makeBins (EggGroupNode root_group) |
The main entry point to EggBinMaker. More... | |
prepareNode (EggNode node) | |
May be overridden in derived classes to perform some setup work as each node is encountered. More... | |
bool | sortsLess (int bin_number, const EggNode a, const EggNode b) |
May be overridden in derived classes to create additional bins within a particular bin number, based on some arbitrary property of nodes. More... | |

__init__ () | |
__init__ (const EggObject copy) | |
clearUserData () | |
Removes all user data pointers from the node. More... | |
clearUserData (TypeHandle type) | |
Removes the user data pointer of the indicated type. More... | |
EggUserData | getUserData () |
Returns the user data pointer most recently stored on this object, or NULL if nothing was previously stored. More... | |
EggUserData | getUserData (TypeHandle type) |
Returns the user data pointer of the indicated type, if it exists, or NULL if it does not. More... | |
bool | hasUserData () |
Returns true if a generic user data pointer has recently been set and not yet cleared, false otherwise. More... | |
bool | hasUserData (TypeHandle type) |
Returns true if the user data pointer of the indicated type has been set, false otherwise. 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... | |

A specialization on EggBinMaker for making polysets that share the same basic rendering characteristic.
This really just defines the example functions described in the leading comment to EggBinMaker.
It makes some common assumptions about how polysets should be grouped; if these are not sufficient, you can always rederive your own further specialization of this class.

__init__ | ( | ) |

setProperties | ( | int | properties | ) |
Sets the set of properties that determines which polygons are allowed to be grouped together into a single polyset.
This is the bitwise 'or' of all the properties that matter. If this is 0, all polygons (within a given group) will be lumped into a common polyset regardless of their properties.
