Keywords

💡Chat Avatar

Chat Avatar is an AI tool that is capable of generating photorealistic 3D avatars. It uses either conversational text or multiple images to create these avatars. In the video, the tool is used to create a model of the actress Scarlett Johansson and is also demonstrated to generate avatars in various styles such as 'hero style' and 'tunify style'. It's central to the video's theme of showcasing how AI can be used to create realistic 3D models from textual descriptions or images.

💡Photorealistic 3D Rigged Model

A photorealistic 3D rigged model refers to a three-dimensional representation of an object or character that closely resembles real-life visuals and is equipped with a rigging system that allows for movement and animation. In the context of the video, the Chat Avatar tool generates such models, which are shown to match the original images of the actress used as a base, demonstrating the high level of detail and realism the technology can achieve.

💡Dream Face

Dream Face is the technology behind the Chat Avatar tool, which enables it to create realistic 3D characters. The video mentions a published paper on this technology, indicating that it is a researched and developed method for generating 3D avatars. It is a key component of the Chat Avatar's functionality and is integral to the video's demonstration of creating 3D models from images or text.

💡Text-to-Avatar Generation

This process involves using text prompts to generate a 3D avatar. The Chat Avatar tool interacts with the user through a chat interface, asking questions about the character and creating prompts for the user to refine the avatar's design. In the video, the user generates a model of Scarlett Johansson by typing in her name, which is a clear example of text-to-avatar generation in action.

💡Image-to-Avatar Generation

This is the process of uploading one or more images to create a 3D avatar. The video demonstrates this by uploading a single image and later, multiple images to generate a composite 3D model. The user can adjust the weight of each image to influence the final model, showcasing the flexibility and customization options available in the Chat Avatar tool.

💡Avatar Styles

The video discusses different styles that can be applied to the generated avatars, such as 'hero style' and 'tunify style', which are reminiscent of styles seen in Pixar and Disney characters. These styles are applied to the base model to give it a distinct look and personality, demonstrating the customization capabilities of the Chat Avatar tool.

💡Base Mesh

The base mesh is the initial 3D model structure that forms the foundation of the final 3D avatar. In the video, the base mesh is shown to match the original image upon which the avatar is based, indicating the accuracy of the Chat Avatar tool in creating a model that is faithful to the source material.

💡Rigged Body

A rigged body in 3D modeling refers to a model that has an underlying system of controls, often visualized as a skeleton, which allows for the manipulation of the model's pose and movement. In the video, the Chat Avatar tool provides the option to include a rigged body when generating the model, which is essential for animation purposes.

💡Blender Add-in

The Blender add-in for Chat Avatar is a plugin that allows users to import the generated 3D avatars into Blender, a popular 3D modeling and animation software. The video demonstrates how to install and use this add-in to bring the avatar into Blender, highlighting the tool's integration with existing 3D modeling ecosystems.

💡EV Render

EV Render, or Eyeon Render, is a rendering engine that can be used within Blender to produce high-quality images or animations. The video mentions switching to EV render mode to check the texture of the eyes on the imported 3D model, indicating its use for evaluating the final visual output of the avatar.

💡Blend Mode

The blend mode in 3D rendering and graphics determines how the colors of an object blend with the colors of the layers beneath it. In the context of the video, changing the blend mode to 'Alpha Hashed' is shown as a method to correct the appearance of the eyes' texture in the 3D model, demonstrating a common technique for adjusting visual effects in 3D rendering.

💡Shape Keys

Shape keys in 3D modeling are a set of predefined shape variations for a model that can be morphed between to create animations or different expressions. The video references checking the shape keys of the model to ensure that the facial expressions work correctly, which is a common practice in character animation to add lifelike movements to the avatar.
