ehmdjii@Posted: Thu Jan 11, 2007 11:16 pm : hello,
i am writing an md5exporter in mel.
if i understood it then the baseframe part in an md5anim file is a frame to which all other frames are relative. right?
my question is how do i get the baseframe?
what is it? is it the bindbose?
technically i can choose the baseframe myself as long as the relative joint rotations and translations in the other frames are correct. right?
Kamikazee@Posted: Thu Jan 11, 2007 11:23 pm : I thought there are already some importers/exporter written for Maya, so you could try to take a look in those. (Given that they are made in MEL too.)
ehmdjii@Posted: Fri Jan 12, 2007 10:58 am : really?
i have been searching for a maya (8) exporter for a long time now, but wasnt successful yet. if there are some, i'd be glad if you could point me to them.
elusive@Posted: Fri Jan 12, 2007 11:20 am : There is a md5toMaya importer that works very well.
Exporting animations from Maya to md5 is only possible with the MayaImportX86.dll from Doom3 afaik.
But this dll is only avaible for Maya 4-7 unfortunately.
ehmdjii@Posted: Fri Jan 12, 2007 11:26 am : thanks.
yepp the dll has not been working for maya8 for me.
maybe i can look into that importer to get information for my exporter.
but back to the original question:
what exactly is the definition of this "baseframe" int the md5anim file.

Yep that's right. If you use the first animation frame as the baseframe instead of the bindpose, chances are that you can save some md5anim filesize because values that never change from their baseframe value don't have to be included in the animation data.
ehmdjii@Posted: Sat Jan 13, 2007 8:39 pm : thanks der_ton.
i know you are more into max and blender, but do you by any chance know a way on how to get the weights positions in maya?
der_ton@Posted: Sun Jan 14, 2007 10:39 am : I don't know MEL or Maya well, but in Blender and Max there is no such thing as weight positions. You have to calculate the md5 weight positions from the vertex positions and the bone transform matrices. A "weight position" is the position of that weight's vertex, expressed in that weight's bone's local coordinate space.
weight.pos = vertex.bindpose_pos * inverted(bone.bindpose_modelspacematrix)
In other words, the weight position is such that
vertex.animated_pos = weight.pos * bone.animated_modelspacematrix
which is the core of skeletal animation, and which probably looks more familiar.

elusive@Posted: Fri Jan 12, 2007 11:20 am : There is a md5toMaya importer that works very well.
Exporting animations from Maya to md5 is only possible with the MayaImportX86.dll from Doom3 afaik.
But this dll is only avaible for Maya 4-7 unfortunately.
ehmdjii@Posted: Fri Jan 12, 2007 11:26 am : thanks.
yepp the dll has not been working for maya8 for me.
maybe i can look into that importer to get information for my exporter.
but back to the original question:
what exactly is the definition of this "baseframe" int the md5anim file.

Yep that's right. If you use the first animation frame as the baseframe instead of the bindpose, chances are that you can save some md5anim filesize because values that never change from their baseframe value don't have to be included in the animation data.
ehmdjii@Posted: Sat Jan 13, 2007 8:39 pm : thanks der_ton.
i know you are more into max and blender, but do you by any chance know a way on how to get the weights positions in maya?
der_ton@Posted: Sun Jan 14, 2007 10:39 am : I don't know MEL or Maya well, but in Blender and Max there is no such thing as weight positions. You have to calculate the md5 weight positions from the vertex positions and the bone transform matrices. A "weight position" is the position of that weight's vertex, expressed in that weight's bone's local coordinate space.
weight.pos = vertex.bindpose_pos * inverted(bone.bindpose_modelspacematrix)
In other words, the weight position is such that
vertex.animated_pos = weight.pos * bone.animated_modelspacematrix
which is the core of skeletal animation, and which probably looks more familiar.

thanks a lot der_ton.
anybody happens to know what the corresponding variables are in MEL?
i.e. how do i query vertex.bind_pos and bone.bindpose_modelspacematrix ?
thanks!

ehmdjii@Posted: Thu Jan 11, 2007 11:16 pm : hello,
i am writing an md5exporter in mel.
if i understood it then the baseframe part in an md5anim file is a frame to which all other frames are relative. right?
my question is how do i get the baseframe?
what is it? is it the bindbose?
technically i can choose the baseframe myself as long as the relative joint rotations and translations in the other frames are correct. right?
Kamikazee@Posted: Thu Jan 11, 2007 11:23 pm : I thought there are already some importers/exporter written for Maya, so you could try to take a look in those. (Given that they are made in MEL too.)
ehmdjii@Posted: Fri Jan 12, 2007 10:58 am : really?
i have been searching for a maya (8) exporter for a long time now, but wasnt successful yet. if there are some, i'd be glad if you could point me to them.
