| __init__ (const PandaNode node, const VertexTransform prev) |
|
const PandaNode | getNode () |
| Returns the PandaNode whose transform supplies this object. More...
|
|
const VertexTransform | getPrev () |
| Returns the VertexTransform object whose matrix will be composed with the result of this node's transform. More...

Public Member Functions inherited from VertexTransform |
| accumulateMatrix (LMatrix4 accum, float weight) |
| Adds the value of this transform's matrix, modified by the indicated weight, into the indicated accumulation matrix. This is used to compute the result of several blended transforms. More...
|
|
| getMatrix (LMatrix4 matrix) |
|
UpdateSeq | getModified (Thread current_thread) |
| Returns a sequence number that's guaranteed to change at least every time the value reported by get_matrix() changes. More...
|
|
| multMatrix (LMatrix4 result, const LMatrix4 previous) |
| Premultiplies this transform's matrix with the indicated previous matrix, so that the result is the net composition of the given transform with this transform. The result is stored in the parameter "result", which should not be the same matrix as previous. More...

Public Member Functions inherited from TypedWritable |
object | __reduce__ () |
|
object | __reduce_persist__ (object pickler) |
|
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...

Public Member Functions inherited from TypedObject |
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...
|
|
Public Member Functions inherited from ReferenceCount |
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...

This VertexTransform gets its matrix from the Transform stored on a node. It can also compose its node's transform with another VertexTransform, allowing you to build up a chain of NodeVertexTransforms that represent a list of composed matrices.
