Bones debug output:

I guess this means I need to check the original values versus the provided values. I also need to check if I need to multiply by the parent.

Got bones and weights working, next step is to figure out how to implement animations.

self.setMatrix(matrix)

Example Code:

if rotKeyType == 0 or rotKeyType == 1 or rotKeyType == 4:
self.rotKeyType = noesis.NOEKF_INTERPOLATE_LINEAR
else:
print("WARNING: Unsupported rotation key type:", rotKeyType)
return
for i in range(0, numKeys):
if rotKeyType == 0 or rotKeyType == 1:
#quats
keyTime = bs.readFloat()
w = bs.readFloat()
keyVal = NoeQuat( (bs.readFloat(), bs.readFloat(), bs.readFloat(), w) ).toMat43(1).toQuat()
self.rotKeys.append(NoeKeyFramedValue(keyTime, keyVal))
elif rotKeyType == 4:
#radians
xyz = [ [], [], [] ]
for i in range(0, 3):

for j in range(0, numSubKeys):
keyTime = bs.readFloat()
if radianKeyType == 0 or radianKeyType == 1:
xyz[i].append(NoeKeyFramedValue(keyTime, bs.readFloat()*noesis.g_flRadToDeg))
elif radianKeyType == 2:
#possible todo - interpolate as bezier
xyz[i].append(NoeKeyFramedValue(keyTime, bs.readFloat()*noesis.g_flRadToDeg))
bezierIn = bs.readFloat()
bezierOut = bs.readFloat()
else:
print("WARNING: Unsupported radian rotation type:", radianKeyType)
return
#this is largely untested, because the model i found using it only used it for the eyes,
#and it's hard to tell if it really works just based on eyes. (that's what she said)
xyz = rapi.mergeKeyFramedFloats(xyz)
for anglesKey in xyz:
self.rotKeys.append(NoeKeyFramedValue(anglesKey.time, NoeAngles(anglesKey.value).toMat43_XYZ().toQuat()))
It looks like key framed value is going to be the best option for implementing the version of animations I have, which defines a time and then gives a set of transformations at that given time.
