I thought I would post this even though it is in it's early stages. It isn't ready for the WIP board yet.

How it works:
I am using Enhanced Animations to extract the animation.
The editor will make a Skeletal Structure by creating bones.
The information is applied to a Skeletal Structure.

To Do:
- Another character with a different bone structure can play the animation I extracted. Effectly copying animation from one character to another.
- Another idea I had was to do this on a vertex level.
- Rag Dolls
- Blending From Physics + Animation. (Using procedural animation to get into position for playing the next animation)
- Bone Editor: Add bones to any object with or without limbs for animation and ragdollin.

ScreenShots:

What I am Demonstrating in this ScreenShot:
- Make Capsule Command
- Animation
- Joints

What I am working on: Getting it to work for Enhanced Animation Data.



What I am Demonstrating in this ScreenShot:
- Character Shop Default Data (Cleaning up the Data took forever!)
- Data Loaded Successfully.
- Save/Load Feature Finished

What I might add: 3D Lines



What I am Demonstrating in this ScreenShot:
- Default.DBO object with limbs + links
- 3D Lines

What I might add:
- Set Joint Names
- Bone Limbs
- Set Bone Names
- Scale Data



Current Problem:
There a small problem I can't seem to figure out. I have Limb Offsets and I need to calculate the Limb World Position. I played around with this for a few weeks and can't seem to figure it out.

I found somewhere on the forums:
World Position = Limb Parent Position + Limb Offset and I tried it and it didn't work.

Edit: No, using Position Limb won't work for what I am doing. I need the algorithm for future features. Thanks.

Edit: Here is the complete bone structure:



@ Mod - Can you change Thread to: Skeletal animation? It would best explain what I am actually trying to do.

I hope to get a demo up soon!

LIMB POSITION command maybe?

I must protest.

The subject header of this thread is VERY misleading. I did not get what I was expecting!!!

@Brendy boy - The animation data is all offsets. I need to convert the offsets to world positions.

@Neco - It is your problem if you are not getting what you are expecting. :p

Animation + RagDoll though a Skeletal Bone Structure is what you should expect once I release a demo. :p

I heard not having a sense of humor can be fatal.

Lighten up a little...

Overhalling the entire demo to look more like Character Shop. Working on building a default bone structure.

I'll be very impressed and happy if you can achieve what you are aiming for here. Applying the animation from one object to another with different bone structures would be very difficult...

Best of luck to you, keep it up!

So this would have somewhat the same features that you have in 3ds Max to rig character? Something like 3ds Max biped?
That would be very useful, atleast for people who don't own Max.

The physics -> animation -> physics sounds very interesting, looking forward to hear more!

@TuPP3 - In 3DS max I would think that vertexs are bound to each bone. This was one of my ideas to be implemented at a later time.

Been quite busy. I managed to get the default bone structure data completed. I have to write a few functions to automatically adapt the default bone structure to another bone structure. This will take a while.

This is Interesting! Have you thought about implementing BVH animation to this somehow? I've been meaning to utilize BVH in my upcoming projects. Having over 2500 free animations from
http://www.cgspeed.com/2010/07/cgspeed-daz-friendly-release-of-over.html
to choose from with your system would rock the house! The BVH format seems suitable for bone systems.

@Todd Riggins - It is on my todo list.

Right now I writing my own bone format as a memblock. A memblock can be added to an object. (.dbo) I am just extracting animation data from one object and applying to another with a seperate bone structure.

My ToDo List:
- Default Structure
- Skeleton/Bone Editor
- RagDolls
- Read in BVH Files
- Add Bones to objects such as plants + Apply physics. = Plants with physics!

@Everyone -
Sorry, but I have been busy so there hasn't been much progress.

Updates:

Sorry, things are progressing slowly. I finally finished the default data structure in the form of a memblock. Saved and Loaded Successfully.

What data I have so far:
- Default Joint List:

- Limb Links/Parent Data
- Default Joint Position Data

When I finish a few things I will have two files. A .dbo with the Joint Position Data and the Default Joint List with Parent Data.

What I am working on next:
- Sort Joints According by Parent, Child, Parent...
- Scale the Data to Model Loaded
- Draw 3D Lines instead of the Default Model
- Joint Snap Tool: Line up Joints to the Default Joint Strucuture
- Auto Assign: Automatically Assign Joints from the Model to the Joint Structure

Here is a screenshot:


Still haven't had much help with my problem. It would greatly help me when I get around to the animation part of this project.

Current Problem:There a small problem I can't seem to figure out. I have Limb Offsets and I need to calculate the Limb World Position. I played around with this for a few weeks and can't seem to figure it out.

I found somewhere on the forums:
World Position = Limb Parent Position + Limb Offset and I tried it and it didn't work.

Edit: No, using Position Limb won't work for what I am doing. I need the algorithm for future features. Thanks.

Thanks,

DigitalFury

Sounds like the same problem I was stuck on. Sven B shared code that does this. Here's the link:

I finally got the default.dbo object finished. It took a lot of work with all the limb positions and limb links by re-working the data like a million times. I have an object that I can now base the memblock data off of this object. I can use this object to scale and manipulate the data so it matches another bone structure. I am going to try a quick animation test to make sure that advanced animation will work with this. If it doesn't I have a lot more work to get the animation to apply to this bone structure.

ScreenShot:


Will have more information soon!

Updates:

Few updates to the default bone structure:
- Outputed an Object with limbs and limb links

Working on adding bones to this object.

Enhanced Animation can't be used to copy animation. Each animation file is set to a certain OAC or object and I can't change that data. Also I can't read the OAC data so my only option is learning how the .x format works.

What I am working on now:
- Reading in .bvh files and applying to my default bone structure
- Reading/writing .x animation

I will let everyone know of anything new as I make progress.

I am going to put a pause on this project until next year. I am working on a small video game demo.

I am going to resume researching animation and ragdolls and post updates on this thread or post links to the posts.

Here is a quick demo showing how the editor would work. I am working on some auto create bone algorithms right now.

Check out my project for more details!
