static TypedWritable *const | Null = (TypedWritable*)0L |
This describes the structure of a single array within a Geom data.
Indicates a coordinate-system transform on vertices.
Encodes a string name in a hash table, mapping it to a pointer.
This class defines the physical layout of the vertex data stored within a Geom.
See GeomVertexFormat for the parent class which collects together all of the individual GeomVertexArrayFormat objects.
A particular array may include any number of standard or user-defined columns. All columns consist of a sequence of one or more numeric values, packed in any of a variety of formats; the semantic meaning of each column is defined in general with its contents member, and in particular by its name. The standard array types used most often are named "vertex", "normal", "texcoord", and "color"; other kinds of data may be piggybacked into the data record simply by choosing a unique name.
The layout consists of a list of named columns, each of which has a numeric type and a size.
The columns are typically interleaved within a single array, but they may also be distributed among multiple different arrays; at the extreme, each column may be alone within its own array (which amounts to a parallel-array definition).
Thus, a GeomVertexFormat is really a list of GeomVertexArrayFormats, each of which contains a list of columns. However, a particular column name should not appear more than once in the format, even between different arrays.
There are a handful of standard pre-defined GeomVertexFormat objects, or you may define your own as needed. You may record any combination of standard and/or user-defined columns in your custom GeomVertexFormat constructions.
This is used to tokenify names so they may be used efficiently in low-level Panda structures, for instance to differentiate the multiple sets of texture coordinates that might be stored on a Geom.
InternalNames are hierarchical, with the '.' used by convention as a separator character. You can construct a single InternalName as a composition of one or more other names, or by giving it a source string directly.
TransformStates are the primary means for storing transformations on the scene graph.
Transforms may be specified in one of two ways: componentwise, with a pos-hpr-scale, or with an arbitrary transform matrix. If you specify a transform componentwise, it will remember its original components.
TransformState objects are managed very much like RenderState objects. They are immutable and reference-counted automatically.
You should not attempt to create or modify a TransformState object directly. Instead, call one of the make() functions to create one for you. And instead of modifying a TransformState object, create a new one.

virtual |
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.
Reimplemented from TypedWritable.

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

Called by the BamReader to perform any final actions needed for setting up the object after all objects have been read and all pointers have been completed.

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().
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.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
