Alchemist
Overview :
Alchemist is a technology that utilizes a pre-trained text-to-image model and synthesized data to allow users to edit the material properties of objects in images. It achieves parameterized control over specific material properties, such as roughness, metallicity, base color saturation, and transparency, through fine-tuning on synthesized datasets. The main advantages of this technology include the ability to alter object properties while maintaining the geometric shape and lighting of the image, and even realistically filling in backgrounds, hidden internal structures, and refraction effects when objects become transparent.
Target Users :
Alchemist targets architects, artists, designers, and anyone requiring precise adjustments of material properties within images. This technology is particularly suited for professionals who need to quickly iterate and visualize material changes during the design process, as well as for users looking to creatively edit images without compromising their realism.
Use Cases
Architects use Alchemist to quickly preview the effects of repainting a room.
Artists leverage this technology to adjust material textures in digital artworks, enhancing visual impact.
Designers experiment with material editing using Alchemist during the product prototype design phase.
Features
Provides precise control over material properties in images, such as color, glossiness, or transparency.
Achieves fine adjustments of material properties through fine-tuning on synthesized datasets.
Allows users to edit material properties while preserving the realism of the image.
Handles complex visual component decomposition challenges, such as distinguishing between object shadows and colors.
Supports the use of edited images for 3D tasks, such as NeRF reconstruction, to synthesize scenes from new perspectives.
In user studies, the editing results from Alchemist are found to be more realistic and favored by users compared to baseline methods.
How to Use
1. Select an image that requires material property editing.
2. Identify the material properties you wish to adjust, such as color, glossiness, or transparency.
3. Use the Alchemist model to input the image and editing instructions.
4. Adjust the editing intensity as needed to define the extent of property changes.
5. Observe the output from the Alchemist model and fine-tune based on feedback.
6. If satisfied, utilize the edited image for further design or 3D tasks.

Stable Fast 3D
Stable Fast 3D (SF3D) is a large reconstruction model based on TripoSR that can create textured UV-mapped 3D mesh assets from a single object image. The model is highly trained and can produce a 3D model in less than a second, offering a low polygon count along with UV mapping and texture processing, making it easier to use the model in downstream applications such as game engines or rendering tasks. Additionally, the model predicts material parameters (roughness, metallic) for each object, enhancing reflective behaviors during rendering. SF3D is ideal for fields that require rapid 3D modeling, such as game development and visual effects production.
