Notes on REFERENCES section of Heretic II Corvus model

For frame "conjure11", which is frame #230 in the model...

For location of left hand, which is reference #0...

Origin: (146, 215, 207)- similar, but not quite, vertex 358, 266, 309, 307 or 270
Direction: (141, 175, 266)
Up: (230, 170, 179)

For location of the blade, which is reference #5...

Origin: (30, 138, 246) - similar, but not quite, vertex 258, 211, 208
Direction: (118, 185, 266)
Up: (103, 117, 192)

Note that verteces 208 and 211 are part of the blade geometry.

For nearly all frames, the Origin coordinates for each reference point are
in the range (0..255). The Corvus and Kiera "partfly" (frame 0) have some
negative coordinates and some coordinates greater than 255. Corvus frame 469
has one negative origin.

The Direction and Up coordinates of reference points in many (most?) frames
are outside the (0..255) range.

Although the floating point date type is used to store the coordinates,
all coordinate values are integers.

The references seem to be used mostly to place effects such as Corvus' shadow,
spell origins, and blade flames. They seem in general to be not exactly on the model geometry, but just a short distance away from it.
