class | GeomVertexFormat |
This describes the structure of a single array within a Geom data.
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.

int GeomVertexArrayFormat::add_column | ( | InternalName * | name, |
int | num_components, | ||
GeomVertexArrayFormat::NumericType | numeric_type, | ||
GeomVertexArrayFormat::Contents | contents, | ||
int | start = -1 |
||
) |
Adds a new column to the specification.
This is a table of per-vertex floating-point numbers such as "vertex" or "normal"; you must specify where in each record the table starts, and how many components (dimensions) exist per vertex.
The return value is the index number of the new data type.

int GeomVertexArrayFormat::add_column | ( | const GeomVertexColumn & | column | ) |
Adds a new column to the specification.
This is a table of per-vertex floating-point numbers such as "vertex" or "normal"; you must specify where in each record the table starts, and how many components (dimensions) exist per vertex.
Adding a column with the same name as a previous type, or that overlaps with one or more previous types, quietly removes the previous type(s).
The return value is the index number of the new data type.

ReferenceCount *& | ref_ptr, | ||

BamReader * | reader = NULL |
||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

void ReferenceCount::ref | ( | ) | const [inline, inherited] |
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.
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.

bool TypedWritable::require_fully_complete | ( | ) | const [virtual, inherited] |
Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.
If this is the case, override this method to return true, and be careful with circular references (which would make the object unreadable from a bam file).
