FlashWorld: High-quality 3D Scene Generation within Seconds

Generate 3D scenes in ~7 seconds from text or image prompts with camera trajectory!

Note: This demo uses ZeroGPU with a 15-second budget. Please ensure your camera trajectory is reasonable.

1. Prompts

2. Camera Trajectory

3. Resolution
Resolution (NxHxW)

Output

Instructions:

  1. Optional: Upload an image prompt
  2. Optional: Enter a text description
  3. Required: Provide camera trajectory as JSON
  4. Select resolution (24 frames recommended)
  5. Click "Generate 3D Scene"

The camera JSON should contain an array of cameras with:

  • quaternion: [w, x, y, z] rotation
  • position: [x, y, z] translation
  • fx, fy: focal lengths (pixels)
  • cx, cy: principal point (pixels)

Tips:

  • Generation takes ~7 seconds on GPU
  • Download the PLY file to view in 3D viewers
  • Use reasonable camera trajectories (not too many frames)
