New Animation System for Irrlicht

buhatkj · Post by **buhatkj** » Tue May 29, 2007 4:17 am

Updated from SVN, and once I added CBoneSceneNode.h, .cpp and IBoneScenenode.h to the VC++ 2005 project everything compiled nicely. First thing I noticed is that when my b3d mesh loads up in my test app, it's animations automatically play at the proper speed instead of being ridiculously slow, that's an improvement by itself! I will test out some more stuff now and let y'all know.

but is the joint control only for b3d format or also for .x and .ms3d formats?

All the formats will be using the same animator with the new animation system, so the bone control will work for all formats. But the x and ms3d loaders haven't been converted over yet. If none is willing to convert them, I'll do it when I have some time. converting them basically involves changing where it stores the data from the mesh, and deleting it's animator stuff.

since i own an milkshape license, i'll volunteer for the ms3d loader... i make no promises about the x loader though, that one will be hard!

thanks bitplane. I haven't got around to getting milkshake yet so it would be tricky.

I'll have a look an the x loader later, if none wants to. hopefully it's not to hard, it already has a separate loader and animator. It's method of loading the mesh is different but the structure of the loaded mesh is pretty similar. It still looks like a fair bit of work.

Wait a second so if I update from SVN I can start manipulating B3D node's bones right away?

well yes, but it's in a branch of the SVN, and you have to change an if(0) to if(1), as I said above.

Luke, I think is way better option b3d than x (me saying this, lol ) , counting on probs people tend to have exporting x, specially from blender...(edit: I have zero probs, but simply, people read less the doc than I

and also, an expert 3d artist does not let certain problems happen...)

Hi there i just tested exporting a model from blender into irrlicht and moving the bones in the SVN version and it works great!

I had absolutely no problems controlling the bones even though I had to set a negative scale to compensate for mirroredmesh/invertednormals!

Good job!

Note to users: To manipulate a bone use "getJointNode()" on an animated mesh and pass that function a string containing the bones name then you can just use "setRotation" on the returned pointer and everything is honkydory, very nice irrlicht integration!

I'm glad it worked for you, I'll develop it and add better support soon. I've switched to Linux, so it may be a few more days before I get use to it all, and can work on the skinnedMesh stuff again.

just need to recompile the latest svn irrlicht? or is it in the .../branches/SkinnedMesh folder?

Luke · Post by **Luke** » Sat Jun 09, 2007 1:12 pm

yeah it's just the ./branches/SkinnedMesh

alright transitions (smoothly blending between two animations) now work.

the new animation plays while blending which I think looks nice

the code could be faster, but it works.

(a bit of joint control(the head looking around), and shows transitions between animations)

(transitions, bumpmapping and looks cool

Hi, everyone!

I've just read this whole thread. First of all, great work Luke & all contributors on this task

I've just got an idea to contribute to Irrlicht, as well as to New Animation System by implementing Lightwave files loader (.lwo and .lws). I'm using LW natively in my engine, and I've implemented really lot of LW-specific features so far.

My question is: What would be the best place to start with the task? B3D loader? I only need several hints and directions just for the beginning.

Best regards to all!
