Purpose
Pixal3D is an AI 3D workspace that runs in the browser, and its core purpose is to turn two-dimensional images into three-dimensional assets. After a user uploads a photo, they can download a textured GLB model; in addition, it offers a separate channel for generating FBX character animations from text prompts. According to the official description, image-to-3D is not about wrapping a generic mesh in a shell, but about elevating the pixels of the source image into geometry, so the side captured by the camera retains the colors, proportions, and surface details from the photo.
Main Capabilities
- Image to GLB (Pixal3D channel): Uses the Pixal3D model to generate a textured GLB asset from a single image, employing pixel-aligned back-projection to project the source pixels back onto the mesh, keeping surface colors and details in their original positions from the photo.
- Trellis 2 comparison channel: Runs Trellis 2 on the same image as a second reconstruction result, so users can keep whichever GLB performs better in the scene.
- Text to motion (Hunyuan Motion): Generates motion files from text prompts, with FBX and JSON downloads provided when the vendor returns them.
- Textured GLB delivery: Successful image-to-3D tasks provide a downloadable textured GLB containing PBR maps (including base color and roughness), which can be previewed on the page and opened in Blender, Unity, Unreal, or any GLB viewer.
- Free browser-local tools: Local tools such as GLB inspection, texture size calculation, and format conversion run entirely in the browser, do not upload files, and do not consume account credits, allowing you to inspect GLB structure, texture memory, and proportions before generation.
How to Use
- Upload an image: Start image-to-3D via a public image URL or by uploading a product, character, object, or concept reference image.
- Choose a 3D model: Pixal3D for high-fidelity image-to-3D, Trellis 2 as a comparison channel for a second reconstruction of the same image, and Hunyuan Motion for text-to-motion. Before generating, check the cost corresponding to the selected model and settings.
- Inspect the 3D result: Before downloading the GLB, verify the geometry, texture recovery, and output readiness status.
- Download the output: After a task succeeds, download the GLB from the workspace or account activity record, and inspect it before importing it into a scene.
The page also embeds the official Pixal3D research demo from the TencentARC Space,For comparison viewing; the samples in the official results gallery come from the official Pixal3D research paper gallery. Each sample shows the input image and a generated 3D GLB mesh link; GLB files open in a new tab.
Applicable Scenarios
According to official content, image-to-3D is suitable for scenarios generating GLB assets from a single photo, and can be used for subsequent import into engines such as Blender, Unity, and Unreal; the Trellis 2 channel is suitable when a second reconstruction result of the same image is needed for comparison; the text-to-motion channel is suitable for scenarios requiring FBX motion and motion JSON rather than a mesh. Topics mentioned in related guides include shooting methods for photos to 3D models, preparation of illustrations and renders for 2D image to 3D, input inspection standards for 3D pixels, STL conversion checks before 3D printing, AI 3D workflows, and upstream licensing for open-source image-to-3D models.
Limitations and Notes
- A single image cannot describe what it never showed. The back of an object, occluded hands, or a cropped bottom still need manual cleanup, so the official emphasis is that input inspection is more important than prompts.
- A default Pixal3D task costs 220 credits, and default Trellis 2 costs 160 credits; higher settings may cost more, so confirm the cost before generating and choose a credit package. New registration and browser trial credits are no longer issued; existing account balances retain their original validity period.
- Pixal3d.ai is an independently hosted service that uses the Pixal3D, Trellis 2, and Hunyuan Motion models through Fal, and is not affiliated with the research team; searching for Pixel3D may point to a different product.
- Regarding whether works made based on Pixal3D models can be sold, the rights depend on the terms of the provided source image and the model behind the selected channel; if a client or marketplace requires proof of commercial access, a commercial certificate can be downloaded from the account.
- Uploaded source images are only used for the generation task initiated, and outputs remain in the account history for re-download.
- The support contact is support@pixal3d.ai, and the account address and the task ID from the activity list must be provided; failed Pixal3D tasks are reviewed for credit refunds according to the refund policy.
Information Not Yet Provided
Official materials do not specify the specific data retention period, the average processing time for generation tasks, the resolution or file size limits for uploadable images, more parameter details beyond each model channel, or export formats other than GLB and FBX/JSON.
