Introduction

GB/T 48021 "Information Technology - Computer Graphics and Image Processing and Environmental Data Representation" is proposed to consist of two parts.

---Part 1: Humanoid Animation Architecture. The purpose is to define the architecture for representing humanoid figures in networked 3D graphics and multimedia environments.

The systematic architecture of the model.

---Part 2: Humanoid Animation Motion Data Animation. The purpose is to define the animation generated using graphics tools, scanning devices, and motion capture.

1 Scope

This document specifies the method for motion capture animation using HAnim humanoid models. The humanoid model consists of models with specific joints and movements.

The data captures the articulated character composition. According to ISO/IEC 19774-1, each character consists of joints and limbs, arranged hierarchically.

structure.

This document includes the following.

a) Motion capture concepts related to humanoid model animation;

b) The concept of motion capture data;

c) Transferring or exchanging motion parameters and motion capture animation data between different humanoid character models;

d) Map the structure of the motion capture data to the structure of the HAnim object;

e) Using HANIM motion capture animation with an interpolator;

f) Define HANim actions using HANimMotion objects;

g) A method for generating and specifying HAnim motion capture animations.

This document describes a standard method for swapping human animations using motion capture technology. This document does not mandate the use of any specific...

The runtime system is used to render HANIM characters or animations.
