Any values between !! are unsigned characters
= +
= "BMT"!v! where v is the version (as unsigned char starting at 0)
= ||||assignBRDF|
= "c"!t!eeeaaafrl where (all floats) e = eye, a = lookAt, f = fov (degrees),
r = aspect ratio, l = lens radius, and t is the type (0 only)
= "p"!t!!nn! !t! is vertexDataFormat !nn! is num vertices
= ppp|pppnnn|pppnnnuu|pppuu p = pnt coord n = normal coord u = uv coord
= "m"!t!!nnnn!!mmmm!
!nnnn! is number of vertices (norms and uvs too if present) !mmmm! is number
of tris is an array of ints (length = 3 * numTris
= "b"!nnnn!!ssss!!c!* !nnnn! is the name index (increase from zero by one
in the file) and !ssss! is the length of the material data (!c!)
= "B"!nnnn! !nnnn! is the name index (increase from zero by one in the file)
= "l"!tt!

= "i"!iiii!!mmmmmmmmmmmmmmmm!"i"!iiii!
iiii is 4byte instance ID (increasing from 0 by one, m* is 3x4 float matrix
= "I"!iiii!!mmmmmmmmmmmmmmmm! as above.

WARNING This file format is not meant to be editable. There may be order specific or numbering specific things in the file. Currently, the material ID is expected to increase by one from zero for each material read in the file. The instance ID is also expected to increase this way (

No swapping done. Assumes all multibyte quantities are in SGI byte order.

RiBMTReader(istream &);

Default Constructor (must have an istream handy)

    RiBMTReader(istream &);

RiBMTReader(RiIORead *in, int instNumber);

Reads an inst. Does not insert it into instList. That's for reading or for instances within this instance.

    RiBMTReader(RiIORead *in, int instNumber);

~RiBMTReader();

Destructor

    virtual ~RiBMTReader();

bool Read();

Read the input stream and return true for success.

    virtual bool Read();

bool ReadGeometry();

Read in everything after the initial header (needed for instances)

    bool ReadGeometry();

bool ReadCamera();

Read in a camera and construct it.

    bool ReadCamera();

bool ReadPolygon();

Read in a polygon and build it.

    bool ReadPolygon();

bool ReadTriMesh();

Read in a polygonal mesh (UNIMPLEMENTED)

    bool ReadTriMesh();

bool ReadMaterial();

Handle materials (somehow)

    bool ReadMaterial();

bool ReadPointLight();

Handle all point/Maya style lights

    bool ReadPointLight();

bool ReadSetMaterial();

Handle setting the current material

    bool ReadSetMaterial();

bool ReadInstance(bool &EOI);

Handle the creation of an instance (after delegating the reading) Note that the creation is a reference as well. EOI is set to true if the Read call closes the instance.

    bool ReadInstance(bool &EOI);

bool ReadReferenceInstance();

Handle the reference of an instance

    bool ReadReferenceInstance();
