An addon uses SMPL's poses and global translation to drive cartoon character in Blender.

Overview

Blender addon for driving character

The addon drives the cartoon character by passing SMPL's poses and global translation into model's armature in Blender. Poses and global translation can be obtained from ROMP or any other 3D pose estimation model. If the model outputs poses and global translation at a high FPS, you can drive cartoon characters in Blender in real time.

Demo

The first demo uses ROMP outputs from the video, which is stored in a file.

The second demo uses ROMP outputs from the webcam in real time.

How to Use the add-on

Data Requester

This addon is a data requester that sends a data request over TCP to 127.0.0.1:9999.It gets one data at a time from the data server.

After running the addon by pressing ctrl+E in Blender, it keeps asking for data until the server closes the TCP connection. You can also press A to close the TCP connection.

Data Server

The data server is bound to 127.0.0.1:9999. After receiving a request from the data requester, one data is sent to the requester.

I've written server.py as a example data server (you only need to know a little about Python TCP to understand it).

Real-time data server can be found in ROMP.You just need to run webcam_blender.sh.

Data Format

The data is a Python list of four elements in the form of [mode,poses,global translation,current keyframe id].

  1. Mode is an integer, 1 for insert keyframe, 0 for no insert keyframe. Insert keyframes and animation rendering can be carried out later. Keyframes are generally not inserted in real-time mode to make real-time driving cartoon characters smoother.
  2. Poses is a list of length 72.
  3. Global translation is a list of length 3. If you don't need global translation, just go into [0,0,0].
  4. Current keyframe id is an integer.If you insert keyframes, you should set it to the correct keyframe id. If you don't insert keyframes, just set it to 0.

Steps

  1. Install the addon in Blender
  2. Run data server
  3. Press Ctrl+E in Blender to run addon
  4. Press A in Blender to stop addon or wait until the data transfer is complete

In step 3, you'd better select Armature, otherwise bugs may occur. Also, the mouse must be placed in the 3D viewport area(where the model is), otherwise the addon will not run.

Something about Blender

If you're not familiar with Blender, I've placed a blender project in the resources folder to help you.All you need to do is open it and follow Steps to achieve the effect shown in the Demo.(It's better to know something about animation in Blender.)

If you need a video background in the demo, select Compositing in the top menu bar, click Open Clip in the Movie Clip, and select your video.

图 2

If you are familiar with Blender and want to use your own models, you should make sure it's armature is SMPL's skeleton. The armature should name Armature and each bone has the same name as the bones in demo model(Only the 24 bones of SMPL skeleton are needed, and the fingers don't need to change their names).

    [simple-romp] How to use it?

    I tried to use it with simple-romp but it did not work. I already created an issue at the ROMP repository and described my problem here and here in detail.

    The author of the ROMP repository answered there:

    About live blender driving, please refer to this repo. https://github.com/yanch2116/CharacterDriven-BlenderAddon My colleague is responsible for maintaining this funciton now. Best regard.

    and closed the issue.

    @yanch2116 So how to solve it?

    My goal is to send the positions and quaternions of ROMP (or any other SMPL based solution) over the VMC protocol to other application (not Blender). Any ideas, whats the best way to do it?

    Also, I would like to know if there is a way to replace the 3D Character before I run the script and process the video so that I don't have to manually change it every time?

    I use ROMP v1.1 on Windows machine. But CDBA works with version 1.0 of ROMP I read installation and using documentation of ROMP v1.0 but i can't figured out all How can i use this addon properly? I'm not good at programming i'm animator and interested in your project. Can you write steps how to install and use ROMP with this addon,please?

    Hi, Looks like change another mixamo character not work

    I have ROMP driven SMPL model looks OK, but when using CDBA (I using script locally) driven mixamo model, result looks wrong:

    image

    I am using this bone mapper in your repo:

    bones_mixamo_smpl_mapper = {
        "Hips": "Pelvis",
        "LeftUpLeg": "L_Hip",
        "RightUpLeg": "R_Hip",
        "Spine2": "Spine3",
        "Spine1": "Spine2",
        "Spine": "Spine1",
        "LeftLeg": "L_Knee",
        "RightLeg": "R_Knee",
        "LeftFoot": "L_Ankle",
        "RightFoot": "R_Ankle",
        "LeftToeBase": "L_Foot",
        "RightToeBase": "R_Foot",
        "Neck": "Neck",

        "RightShoulder": "R_Collar",
        "Head": "Head",

        "RightArm": "R_Shoulder",
        "LeftForeArm": "L_Elbow",

        "LeftHand": "L_Wrist",
        "RightHand": "R_Wrist",
        "LeftHandIndex1": "L_Hand",
        "LeftHandMiddle1": "L_Hand",
        "RightHandMiddle1": "R_Hand",
        "RightHandIndex1": "R_Hand",
    }
    bones_smpl_mixamo_mapper = {v: k for k, v in bones_mixamo_smpl_mapper.items()}
    bone_name_from_index_character = {
        k: bones_smpl_mixamo_mapper[v] for k, v in bone_name_from_index.items()
    }
    
    

    Do u know why?

    also the hand look not right.

  • Detection variable: outputs = {'poses': poses, 'trans': trans[0]}

    Detection variable: outputs = {'poses': poses, 'trans': trans[0]}

    Hey, Yanchxx,

    May I ask, what is the output variable, I think "trans" is the translation between camera and object.

    What are the poses, is it the location x, y, z, or rotation x, y, z, degrees?

    Thank you 👍

  • Use keyframes to prevent pose shaking

    Use keyframes to prevent pose shaking

    I found that the avatar will shake drastically when running the webcam demo. And I set the mode =1 to insert keyframe record the webcam results for playback.

    Now, if we set one more condition for inserting keyframe, only the frame_idx % 3 == 0 or frame_idx % 5 == 0. This would allow the avatar to move along these keyframes much smoother.

    However, is there a way to let the webcam demo runs in real-time using the keyframe strategy I said? This skip keyframe strategy only seems to work with the recorded playback. The character is still moving on each frame when we are actually running in real-time.

    multiple people

    Hey, yanch2116, very impressive job done in visualizing 3D characters. I tested and it works, one question to ask, the code romp_server.py has the setting.show_largest=True, I am thinking, what is the condition with multiple people in the webcamera, when there are many people, the blender character keeps on shifting. Are they ways to solve this? 1, keep on the object tracker in single object_ID 2, visualize multiple 3D characters as input in the camera
