RenderAttribRegistry

from panda3d.core import RenderAttribRegistry

class RenderAttribRegistry

Bases:

This class is used to associate each RenderAttrib with a different slot index at runtime, so we can store a list of RenderAttribs in the RenderState object, and very quickly look them up by type.

Inheritance diagram

static getGlobalPtr() → RenderAttribRegistry

static getMaxSlots() → int

getNumSlots() → int: Returns the number of RenderAttrib slots that have been allocated. This is one more than the highest slot number in use.

getNumSortedSlots() → int: Returns the number of entries in the sorted_slots list.

getSlot(type_handle: TypeHandle) → int: Returns the slot number assigned to the indicated TypeHandle, or 0 if no slot number has been assigned.

getSlotDefault(slot: int) → RenderAttrib: Returns the default RenderAttrib object associated with slot n. This is the attrib that should be applied in the absence of any other attrib of this type.

getSlotSort(slot: int) → int: Returns the sort number associated with slot n.

getSlotType(slot: int) → TypeHandle: Returns the TypeHandle associated with slot n.

getSortedSlot(n: int) → int: Returns the nth slot in sorted order. By traversing this list, you will retrieve all the slot numbers in order according to their registered sort value.

setSlotSort(slot: int, sort: int): Changes the sort number associated with slot n.
