Notes:
Photorealism is a term that refers to the ability of a computer-generated image or animation to closely resemble a photograph or real-life scene. In the context of virtual humans, photorealism refers to the ability of a digital character to look and behave as realistically as a real human.
There are many factors that contribute to the photorealism of a virtual human, including the quality of the 3D model, the accuracy of the facial expressions and body movements, the realism of the skin, hair, and clothing, and the overall level of detail and fidelity in the character’s appearance and behavior.
To achieve photorealism in a virtual human, developers may use a variety of techniques, including high-quality 3D modeling, motion capture, facial animation, and skin and hair rendering. They may also use machine learning algorithms to help generate realistic facial expressions and movements.
Overall, the goal of photorealism in virtual humans is to create digital characters that are indistinguishable from real humans, both in terms of appearance and behavior. This can be used for a variety of applications, including entertainment, training, and education.
- Photorealistic virtual humans are digital characters that are designed to closely resemble real humans in terms of appearance and behavior. These characters are created using a variety of techniques, including 3D modeling, motion capture, facial animation, and skin and hair rendering. The goal of creating photorealistic virtual humans is to create digital characters that are indistinguishable from real humans, both in terms of appearance and behavior.
