Unfortunate Situation of Computer Animation in Video Games

Computer animation in video games is a challenging task because it involves creating a beautiful virtual world populated with characters that Interact with each other. However, previous techniques have failed to deliver high-quality motion and generality. If the quality of motion is high, it does not transfer to new scenes, or the transfer is not of high quality. This situation is unfortunate because it limits the creative freedom of video game developers.

Previous Techniques

Traditional computer animation techniques rely on manually creating key frames. This process is time-consuming and results in stiff and repetitive movements. More recently, computer animation researchers have used motion capture technologies to Record real human movements and transfer these movements to virtual characters. However, this approach suffers from a lack of generality, and the movements do not transfer to new scenes or new characters effectively.

Lack of Quality of Motion or Generality

The lack of quality of motion or generality in computer animation techniques limits the creativity of video game designers. This situation not only affects the development of video games but also has implications for other fields like robotics and virtual reality.

AMP Technique in Virtual Environment

The Adversarial Motion Priors (AMP) technique was presented at SIGGRAPH 2021, offering a solution for the problems of computer animation in virtual environments. The technique creates high-quality motions for characters in video games that can interact with the scene as well.

Dataset of Real Clips of Movements

The AMP technique is Based on a dataset of real clips of movements such as running, jumping, and rolling. The technique learns to use these movements for characters in video games to finish a level.

High-Quality Motions Transferable to New Environments

The AMP technique generalizes to new objects and environments. The high-quality motions created by the technique encourage solving tasks with style.

Generalizes Interactions with the Scene

The AMP technique not only allows characters to run around in the scene but also teaches them to interact with the scene. This capability is a significant innovation in computer animation in video games.

Innovation of the AMP Technique

The innovation of the AMP technique is in its ability to Create high-quality motions that generalize to new environments and objects. Moreover, the techniques encourage solving tasks with style.

High-Quality Motions Encouraged to Solve Tasks with Style

The AMP technique can create high-quality motions that are encouraged to solve tasks with style. This innovation is ideal for video games that require smooth, natural movements.

Generalizes to New Environments and Objects

The AMP technique can generalize to new objects and environments by training with a variety of object types, orientations, and locations.

Strict Testing with External Perturbations

The AMP technique underwent strict testing by computer graphics researchers who tried to sabotage the characters in video games with external perturbations. The characters demonstrated that they could overcome the challenges and complete the task efficiently.

Limitations of the Technique

The AMP technique is not perfect, as its success rates are not at a hundred percent. Moreover, external perturbations like throwing boxes or tripping the characters lower the success rates by 3 to 10 percent.

Success Rates

While the success rates are not at a hundred percent, they are still respectively above 90 percent. Future research may Seek to improve the success rates or filter them to approach near a hundred percent for real applications.

Effects of External Perturbations

The effects of external perturbations on the success rates are observable but are still respectable. Even when the characters are treated badly, they still perform well.

Conclusion

The Adversarial Motion Priors (AMP) technique offers an innovative solution to the challenges of computer animation in video games. The technique creates high-quality motions for virtual characters that generalize to new environments and objects. The innovation encourages solving tasks with style, making the technique a significant milestone in video game development.
