I got rather tired of there being multiple definitions of mostly compatible
plane types (and I need a common type anyway). dplane_t still exists for
now because I want to be careful when messing with the actual bsp format.
The params are eye position, flags and synctype. Provision is made for
reading them from a text block on export, but nothing is done other than
retrieving the text block.
The biggest part of the speedup is reading from blender's image only once
(it seems that every read does so from GL rather than memory: ouch). Also,
cache the results for each color.
The size is actually the average area in quake units of the mesh's
triangles. Again, my results are slightly smaller (0.025).
With this, all calculable fields are set. Only eye position, flags and
synctype remain.
The calculated radius is a smidge (0.05) smaller than the original
(invisibl.mdl), but I think that's due to the difference in source data: id
used the original models, I'm using their output.
Blender must have an active shape key before shape key animation will work.
This fixes the models being locked to the first frame until a shape key is
selected via the UI.
I /did/ see the warning about vertex index 0 in the obj importer script,
but I didn't take it seriously enough. This fixes both the twisted texture
on a couple of faces, and the truly mangled tris when exporting (using
invisibl.mdl for testing).
There seems to be some problems with the UVs, only one frame is exported,
and various model params don't get set (eye position, size, bounding
radius, synctype, flags), but the size and shape look right in qf :).
Except for the normal index in the frame bounds (and potentially frame
names with junk after the terminating nul), the output is identical to the
input for:
mdl=MDL().read("invisibl.mdl")
mdl.write("test.mdl")
But only if they seem to be related (ie, the frame name is the same up to
the number). This will later become optional, but it allows me to test
some of the frame group code.
