Faithful image-to-GLBPixel-aligned 3D

Faithful image-to-GLB with pixel-aligned 3D

Use the fal production path for saved Pixal3D and Trellis 2 GLB jobs, then compare a second model lane before spending cleanup time.

Choose a credit pack to generate. New accounts get 1 free image credit, then 1 more per daily check-in; a default Pixal3D job costs 220 credits. Existing balances keep their original expiry.

Three-model API comparison

Pick the right model lane before spending credits

Pixal3D and Trellis 2 both convert an image URL into GLB assets. Hunyuan Motion uses a text prompt to create FBX motion. The workspace keeps those lanes behind one authenticated task and credit pipeline.

Rehosts provider files to R2 when possible.
Pixal3D
Default image-to-3D lane
fal-ai/pixal3d
API input
image_url, seed, resolution 1024/1536, texture_size, SLat steps, decimation_target
API output
model_glb + PBR texture + seed
Strength
Best default for pixel-aligned reconstruction: image features are back-projected into 3D so the front view stays closer to the source.
Watch point
Requires a public source image URL; cropped, occluded, or low-light subjects still need manual cleanup.
Credit lane
180-390 credits
Trellis 2
Alternative image-to-3D pass
fal-ai/trellis-2
API input
image_url, seed, resolution 1024/1536, decimation_target, texture_size, remesh
API output
model_glb
Strength
Useful when you want a second geometry interpretation before spending time in downstream tools.
Watch point
The mesh can read structure differently, especially on thin parts, so inspect the GLB before handoff.
Credit lane
160-310 credits
Hunyuan Motion
Text-to-motion lane
fal-ai/hunyuan-motion/fast + fal-ai/hunyuan-motion
API input
prompt, seed, duration 0.5-12s, guidance_scale, output_format
API output
fbx_file + motion_json + seed
Strength
Best when the deliverable is timing, pose change, or character animation rather than static geometry.
Watch point
Prompt specificity matters: duration, body part, action order, and ending pose should be explicit.
Credit lane
60 / 80 credits

A character walks forward, turns around, and waves with natural timing.

Detailed accessory sample for Pixal3D
Pixal3D

Detailed accessory

Accessories need high-resolution source images so small material details survive the handoff.

3D pixel, pixel 3D, and 3D AI

Match a 3D pixel, pixel 3D, or 3D AI request to the right lane

A 3D pixel build is the default lane in this workspace: your source image is back-projected so every pixel stays tied to the surface of the GLB instead of being wrapped loosely around it. A search for pixel 3D, or for 3D pixels, means that same image-to-3D pass, and the wider 3D AI comparison adds the Trellis 2 route plus Hunyuan Motion text-to-motion. For the full sequence from a public image URL to an exported GLB, check the credit cost above and run the first job on this page. Starting from a picture? Follow the photo to 3D model shooting guide for photographs, or the 2D image to 3D model guide for illustrations and renders.

FAQ

AI 3D generator: answers before your first GLB

The questions people ask before running an image-to-3D job in this workspace, answered in plain terms.

  1. 1

    What is 3D pixel modeling?

    A 3D pixel search usually means image-to-3D where every pixel of the source picture stays tied to the model's surface instead of being wrapped loosely around it. Pixal3D does this through back-projection, lifting pixel features into 3D so the front view of the generated GLB stays faithful to the reference image. It is not voxel art: the pixel grid does not become a block grid. To run it, upload a clear image or paste a public image URL in the workspace above, choose the Pixal3D lane, and download the textured GLB.

  2. 2

    What is an AI 3D generator?

    An AI 3D generator turns one image or a text prompt into a downloadable 3D model. On pixal3d.ai the image-to-3D lanes return a textured GLB mesh with PBR maps, and the text-to-motion lane returns FBX motion, all run through the Fal provider in your browser with no GPU or install needed.

  3. 3

    How do I turn an image into a 3D model?

    Upload one clear image or paste a public image URL, pick the Pixal3D or Trellis 2 lane, and submit. The workspace previews the GLB in the page and then lets you download it. A full subject, a clean silhouette, and a simple background give the most faithful front view.

  4. 4

    What file formats does the generator output?

    Image-to-3D runs return a GLB mesh with PBR textures that you preview and download in the browser. Text-to-motion runs return FBX plus motion JSON. Free browser tools on this site also convert GLB to OBJ or STL.

  5. 5

    How much does a generation cost?

    Pixal3D runs cost 180 to 390 credits, Trellis 2 runs cost 160 to 310 credits, and text-to-motion costs 60 or 80 credits, with the exact price shown beside the submit button. A default Pixal3D job costs 220 credits, and new accounts get 1 free image credit plus 1 per daily check-in.

  6. 6

    Do I need to install anything or own a GPU?

    No. The hosted workspace runs the models on the provider side, so a browser is enough. Running the open Pixal3D repository locally is a separate Linux and CUDA workflow that you do not need for the hosted lanes.
