**Bam Format** # Bam Format This is the technical documentation for the .bam format. This is generally not useful except for developers who insist on writing their own tools to manipulate .bam files without using the Panda APIs. ## Bam versions The .bam format has a major.minor version scheme. The format is designed to be backward compatible, so that .bam files created with older versions of Panda3D will generally work with newer versions of Panda3D, although occasionally compatibility has been broken due to major changes in the Panda3D structures. Forward compatibility is not considered, though, so Panda3D will refuse to read .bam files with a higher version number. This means you can read Panda3D 1.8 bams in Panda3D 1.9, but not vice versa. As of Panda3D 1.7.1, We try not to bump the .bam version between minor releases of Panda3D, so that .bam files created with Panda3D 1.8.1 will still load in Panda3D 1.8. The table below shows the .bam version associated with each Panda release. The first column shows the Panda version, the second shows which version .bam files it will output (and also the maximum that it will read), and the third shows the minimum .bam version that it will read. | Panda version | Writes | Reads | | ------------- | ----------- | ----- | | 1.0.x | 4.14 | 4.0 | | 1.1.0 | 5.4 | 5.0 | | 1.1.1 | 5.6 | 5.0 | | 1.2.x | 6.3 | 6.0 | | 1.3.x | 6.4 | 6.0 | | 1.4.x | 6.12 | 6.0 | | 1.5.0 | 6.14 | 6.0 | | 1.5.1, 1.5.2 | 6.15 | 6.0 | | 1.5.3, 1.5.4 | 6.16 | 6.0 | | 1.6.x | 6.14 | 6.14 | | 1.7.0 | 6.22 | 6.14 | | 1.7.1, 1.7.2 | 6.24 | 6.14 | | 1.8.x | 6.30 | 6.14 | | 1.9.x | 6.37 | 6.14 | | 1.10.0-1.10.5 | 6.21 - 6.44 | 6.14 | | 1.10.6-1.10.9 | 6.21 - 6.45 | 6.14 | Note that Panda3D 1.10 is able to write older .bam files. This can be done by putting this in Config.prc: ``` bam-version 6 21 ``` When not set, the default is to write the latest supported version that is still readable by the .0 version of that release branch. For example, 1.10.6 through 1.10.9 will write bam 6.44 by default. ## Bam header The bam format is composed of a series of datagrams. Each datagram is prefixed by an unsigned 32-bit size number. Exceptionally large datagrams are encoded by writing 0xffffffff as the size, followed by an unsigned 64-bit integer containing the actual size. Most .bam structures are stored in little-endian format. Certain structures can be stored in a different endian format, where specially tagged as such. Currently, this applies to vertex data. The endianness of this special data is indicated by the file header. .bam files (but not .bam streams) begin with the six-character magic string `pbj\0\n\r`. This can be used to uniquely identify .bam files. It includes a carriage return and newline character to help detect files damaged due to faulty ASCII/binary conversion. This is followed directly by the file header, the structure of which is detailed below. When a version number is indicated, it indicates that a field has been added in that version, so a backward compatible reader should not read that field if the .bam version is lower than the indicated number. | Bytes | Type | Name | Minver | Description | | ----- | ------ | ---------------- | ------ | ---------------------------------------------------------------------------------------------------------------------------------- | | 4 | uint32 | | | Size of header datagram (should be 6) | | 2 | uint16 | bam_major_ver | | Major .bam version, as detailed above. | | 2 | uint16 | bam_minor_ver | | Minor .bam version, as detailed above. | | 1 | uint8 | file_endian | 5.0 | Endianness of vertex data (everything else is little-endian). 0 if big-endian, 1 if little-endian. | | 1 | bool | stdfloat_double | 6.27 | True if fields marked "stdfloat" contain 64-bit floating point numbers instead of 32-bit. Before 6.27 they were implicitly 32-bit. | ## Objects What follows the header is essentially a list of objects. There is usually (but not necessarily) a single root object at the beginning, and all children and other dependent objects follow. For a .bam file containing model/animation data, this is the root node of the scene graph. Each object has a sequentially increasing unique ID, by which it is referenced by other objects. The special ID 0 is reserved to indicate a NULL pointer. Of note is that object IDs are stored as 16-bit unsigned integers, but as soon as an object with ID 65535 is encountered, all future object IDs and references to it are stored as 32-bit integers. An object may occur more than once in the .bam stream, for example if it was modified since it was first written. The first time an object is written it also specifies type information. Each type is identified with an arbitrarily chosen type index, followed by the name of the type. It also contains hierarchical information about the parent classes, which is useful when a reader does not understand eg. a PandaNode derivation but will still be able to reconstruct the base node. Information about each type is only written the first time a type with a particular index is encountered. ## Object stream Before version 6.21, the header was followed by a continuous stream of objects. This means that in order to determine whether the object and its dependencies have been completed, the reader must keep track of the number of objects referenced Version 6.21 resolves this by inserting special codes in the object stream that can be used to specify a nested structure of objects. When writing out an object, a `push` code is first inserted, after which the object is written out, followed by the objects that were referenced the object, each of them also prefixed by an object code. Only then is the `pop` written out, indicating that the object is complete. Of course, the dependent objects themselves may write nesting `push` and `pop` codes, so in order to determine whether an object structure has been completely read, it is necessary to count the number of `push` and `pop` codes encountered. The object code is a single 8-bit integer that can take on the following values: | Value | Name | Description | | ----- | --------------- | ---------------------------------------------------------------------------------------------- | | 0 | BOC_push | Increments the nesting level. Followed by a single object definition. | | 1 | BOC_pop | Decrements the nesting level. Followed by another object code. | | 2 | BOC_adjunct | This code is followed by a single object. This is the implied value before 6.21. | | 3 | BOC_remove | Followed by a list of object IDs that are no longer important to the file and may be released. | | 4 | BOC_file_data | Followed by an auxiliary data record that may be requested by certain objects. | As an example, this is what the structure looks like for a node referencing two different textures: ``` PUSH PandaNode ADJUNCT Texture ADJUNCT Texture POP ``` Since it may be difficult for a writer to know before writing an object whether it will reference other objects, the following is also perfectly legal: ``` PUSH PandaNode PUSH Texture POP PUSH Texture POP POP ``` ## Type encoding Unless specified otherwise, all integer types are little-endian. (Note that there is an endianness field in the header, but it only affects geometry buffer data.) - bool: Booleans are stored as a single byte that is either 1 (for true) or 0 (for false). - string: Strings are encoded as a uint16 length indicating the number of characters that directly follow. - stdfloat: Usually float32, but can be float64 if stdfloat_double in the header is set to 1. - pointer: An integer identifying the referenced object. 0 represents the NULL pointer. This is uint16 until object ID 0xFFFF has been encountered in the stream, then it becomes uint32. Arrays of multiple objects are usually expressed by first outputting a length field, which itself can vary on size depending on how many objects are usually present in this array. ## Object reference This is an incomplete list of objects and their .bam encoding scheme. The "minver" column indicates which bam version the field was introduced in; if writing a bam file with a version older than that, the field should not be written out. Blocks in grey indicate either an optional field (the presence of which depends on the value of the indicated other fields) or a block that is repeated for each element in an array (usually indicated by a preceding length field). ### Geom

### TransformState All nodes must have a TransformState reference, but it is perfectly fine to create a single TransformState referring to the identity transformation and refer to that in all nodes that don't have an explicit transform. Since transform states are immutable in Panda3D, there are no negative consequences from sharing them between different nodes. Transformations can be expressed in various ways. Besides the specially marked "identity" and "invalid" transforms, there may be componentwise specification of the transformation, or a matrix can be specified. Both may be specified, but this is not necessary as Panda3D will calculate one from the other at request.
