00:00As you go into VR and you have an avatar version of the AI and you can talk to them there,
00:07that's going to be really compelling. It's at a minimum creating much better NPCs and experiences
00:14when there isn't another actual person who you want to play a game with. You can just have
00:18AIs that are much more realistic and kind of compelling to interact with.
00:23Meta has launched a new text-to-3D generator AI that will transform your workflow.
00:28This revolutionary tool lets you create 3D models from simple text descriptions
00:33in a fraction of the time. Imagine crafting intricate characters, designing stunning
00:39environments, or generating unique props, all with just a few words. Meta's text-to-3D is
00:46your ultimate companion. Let's delve into its full capabilities. Meta's AI text-to-3D generator.
00:54Meta is known for its constant evolution in the realm of artificial intelligence,
00:59particularly with its content tagging system that adapts to new types of content and trends.
01:05Beyond these day-to-day applications, Meta's research wing is delving into more groundbreaking
01:10areas of AI technology. One of their most innovative developments is an AI tool called
01:15Meta 3D Gen. Meta 3D Gen represents a big leap forward in the field of generative AI.
01:22This tool is designed to generate 3D assets from text descriptions with a high degree of accuracy,
01:28as shown by the images on Meta handle on thread. The ability to create 3D models based solely on
01:34textual input is a game changer, especially for industries that rely heavily on digital
01:40content creation, such as gaming, virtual reality, and film. Meta claims that 3D Gen
01:46can produce outputs at speeds three to sixty times faster than professional artists. This
01:52remarkable efficiency does not come at the expense of quality. On the contrary, 3D Gen generates
01:58assets with high-resolution textures and material maps that are superior in quality compared to
02:04previous state-of-the-art solutions. This performance boost is achieved at three to ten
02:09times the speed of earlier methods, highlighting the system's huge advancements in both speed and
02:14quality. One of the standout features of Meta 3D Gen is its support for physically-based rendering.
02:21This is essential for creating 3D objects that look realistic under various lighting conditions,
02:26as depicted in the example here. This technology simulates the physical properties of materials,
02:32allowing the 3D assets generated by Meta 3D Gen to react to light in a way that mimics real-world
02:38materials. This means that objects created using this tool can appear hyper-realistic, enhancing
02:44the visual experience in any application where they are used. Moreover, Meta 3D Gen is not just
02:50about creating new 3D assets from scratch. It is also highly versatile in its ability to re-texture
02:56existing models. Whether the original model was generated by AI or created by an artist, Meta 3D
03:03Gen can apply new textures based on fresh text prompt. This feature allows for a high degree of
03:08customization and flexibility, enabling users to alter the appearance of 3D models to fit different
03:15themes or requirements without having to rebuild them from the ground up. How it works. Meta's 3D
03:21Gen uses a two-stage method that leverages the strengths of two foundational generative models,
03:27Asset Gen and Texture Gen, to create high-quality 3D models for immersive content.
03:32This approach involves a division of labor between the two models, where each focuses
03:37on different aspects of the 3D creation process, allowing for enhanced control and refinement,
03:44much like the way text-to-image generators function. The first stage in this process is
03:48handled by Meta's Asset Gen. Asset Gen is responsible for generating the 3D geometry
03:54of the object. When provided with a prompt, Asset Gen rapidly constructs the basic shape
04:00and structure of the object in three dimensions. This initial stage takes only about 30 seconds,
04:06during which the model also applies basic textures and physically-based rendering to the 3D object.
04:13Once the basic 3D geometry is created by Asset Gen, the process moves to the second stage,
04:19where Texture Gen takes over. Texture Gen's role is to refine and enhance the textures
04:24applied to the 3D object, ensuring high resolution and detailed surface properties.
04:30This optimization process happens swiftly, within the next 20 seconds. Texture Gen meticulously
04:37works on the textures, improving their quality and making them more realistic and detailed.
04:42This stage is crucial because it significantly enhances the visual fidelity of the 3D model,
04:48making it suitable for immersive content where high-quality visuals are essential.
04:53The separation of tasks between Asset Gen and Texture Gen allows for greater control over the
04:583D modeling process. Users can focus on refining specific aspects of the model independently,
05:05similar to how text-to-image generators allow for iterative refinement of generated images.
05:10Additionally, users can provide further textual inputs to retexture previously created 3D shapes.
05:17This feature is particularly useful for those who need to modify the appearance of an object
05:21without starting from scratch. For instance, if a user is satisfied with the shape of a 3D model,
05:27but wants to change its texture to fit a different context or aesthetic, they can simply input new
05:32textual instructions, and Texture Gen will apply the new texture accordingly. This flexibility
05:38significantly enhances the usability and adaptability of the 3D Gen system. You can
05:43easily make those adjustments without having to redo the entire model from scratch.
05:483D Gen Generation Process
05:51Meta 3D Gen generation process involves several sophisticated steps to achieve
05:57photorealistic quality, leveraging advanced techniques in computer graphics and machine
06:02learning. The first step in Meta 3D Gen's process is generating multiple views of the object. These
06:09views are not just simple 2D images, but are enhanced with detailed information about the
06:14object's appearance. Specifically, the views include factored shaded appearance in albedo.
06:20The shaded appearance refers to how the object looks under different lighting conditions,
06:25while albedo represents the inherent color of the object, independent of lighting and shadows. By
06:31capturing this information, Meta 3D Gen can accurately represent the object's visual properties
06:37from different angles. Next, the system reconstructs key physical attributes of the
06:42object, including its colors, metallicity, and roughness in a 3D space. These attributes are
06:49crucial for creating realistic models because they affect how the object interacts with light.
06:55For instance, metallicity determines how metallic or non-metallic the surface appears,
07:00influencing reflections and highlights. Roughness affects the surface texture,
07:06dictating how light scatters when it hits the object. To achieve this reconstruction,
07:11Meta 3D Gen uses a neural network trained via a method called deferred shading loss.
07:17Deferred shading is a technique in computer graphics where the rendering of light and
07:22shadow is postponed until after the initial geometry and texture information has been
07:27processed. By applying a deferred shading loss, the network learns to accurately recreate the
07:32object's appearance in 3D by comparing its predictions to the target appearance under
07:37various lighting conditions. This approach ensures that the reconstructed model maintains
07:42high fidelity to the original object. A critical output of this reconstruction process is the sine
07:48distance function. A sine distance function provides a mathematical representation of the
07:53object's surface by indicating the distance of any point in space to the closest point on the
07:58object's surface. From this function, a 3D mesh can be extracted. The mesh represents the object's
08:05geometry as a network of vertices, edges, and faces, forming a detailed structure that can be
08:12rendered in 3D space. After the mesh is created, a final texture refinement step is performed in
08:18the UV space. UV space refers to a 2D representation of the 3D surface used for texture mapping.
08:25This process involves unwrapping the 3D model onto a 2D plane where textures can be applied
08:30more efficiently. The texture refinement step significantly enhances the sharpness and detail
08:36of the model by fine-tuning the textures mapped onto the 3D surface. This step ensures that even
08:42the smallest details are accurately represented, resulting in a highly realistic and visually
08:48appealing final model. Potential application. The implications of this technology are vast.
08:55For instance, in the gaming industry, developers can use Meta 3D Gen to quickly generate a wide
09:01variety of assets, reducing the time and cost associated with manual 3D modeling.
09:07Similarly, in virtual reality, where the creation of immersive environments is key,
09:12this tool can expedite the process of populating these virtual spaces with detailed and realistic
09:18objects. In film and animation, artists can leverage Meta 3D Gen to produce detailed props
09:24and environments more efficiently, allowing them to focus more on creative storytelling.
09:29Additionally, the ability to generate and retexture 3D models based on text descriptions
09:35makes this tool accessible to users who may not have extensive experience in 3D modeling. By
09:41lowering the barrier to entry, Meta 3D Gen democratizes the creation of high-quality 3D
09:47content, enabling more people to participate in the production of digital assets. Beyond its immediate
09:52applications, Meta 3D Gen also opens up new possibilities for future innovations. As AI
09:59continues to improve, it could potentially generate even more complex and detailed models,
10:05further pushing the boundaries of what is possible in digital content creation.
10:10Moreover, the integration of this technology with other AI-driven tools and platforms could lead to
10:15even more sophisticated and automated workflows, transforming the way industries approach 3D
10:21modeling and rendering. The Future of 3D Generator
10:26One of the big issues in 3D generation is creating models that look convincing
10:30in both virtual reality and real-world applications. This difficulty arises because
10:36VR environments are particularly unforgiving when it comes to artificial detailing. In VR,
10:42users can view objects up close and from multiple angles, making any imperfections
10:47or lack of detail immediately noticeable. To create a believable experience, it is crucial
10:52to have as much detail as possible in the actual geometry of the models, rather than relying solely
10:58on textures. Currently, many AI models that generate 3D content tend to produce low-resolution
11:04geometry and rely heavily on textures to approximate details. This approach can work
11:10for certain applications where the models are not examined too closely. However, in VR, this method
11:16falls short because textures alone cannot provide the depth and realism needed when users can
11:22scrutinize every aspect of the environment. Metacompany, known for its advancements in AI
11:27and large language models like the recent Lama3, is addressing this challenge with its tool Meta3DGen.
11:34Meta3DGen aims to create more sophisticated 3D models that can meet the high standards required
11:40for VR and real-world applications. One of the main obstacles in this field is the limited
11:46availability of high-quality 3D datasets for training AI models. Unlike images and videos,
11:52which are abundant and easily accessible, 3D data is much scarcer and more complex to work with.
11:59Despite these challenges, the examples provided by Meta3DGen are remarkably promising. The tool
12:05leverages Meta's expertise in AI to push the boundaries of what is possible in 3D generation.
12:11By focusing on enhancing the actual geometry of the models, Meta3DGen can produce more detailed
12:18and realistic outputs. Meta is setting a new standard for 3D generation in both VR and real-world
12:25applications. The advancements made by Meta in the 3D generation space have broader implications
12:31for the industry. As tools like Meta3DGen become more sophisticated, they will enable creators and
12:38developers to produce higher-quality content, more immersive VR experiences, and more realistic 3D
12:45models in various applications, from gaming and entertainment to design and architecture.
