Text, image, or video in
Start from a prompt, one reference image, or one short video. Combine text with either media type — image and video stay mutually exclusive.

AI 3D World Generator
Turn text, an image, or a short video into an explorable 3D world. Walk through the scene in full screen, frame any view, and send snapshots back to Canvas for your next image or video.
Optional: add one image or one video (up to 30s). Image and video cannot be used together.
What is an AI 3D world generator?
An AI 3D world generator creates a navigable three-dimensional scene from text, an image, or a short video. On Topview, the output is a Gaussian Splat (SPZ) world you can enter in full screen, move through with keyboard and mouse, and capture into Canvas — not a downloadable mesh file for printing or game engines.
Why create a 3D world here
Built for creators who need explorable scenes that feed the rest of their image and video workflow.
Explorable Gaussian Splat worlds
Results open as immersive SPZ scenes you can walk through, not flat skyboxes or static previews.
Screenshot back to Canvas
Capture any viewpoint in ratios from 9:16 to 21:9 and drop a new image node next to your 3D World card for downstream creation.
Marble 1.1 and Marble 1.1 Plus
Choose Marble 1.1 for a standard world or Marble 1.1 Plus for a Larger World. Credits are shown before you generate.
Three ways to start a 3D world
Match the input to the scene you already have.
Text to 3D world
Describe location, architecture, lighting, and mood. Best when you are inventing a space from scratch.
Image to 3D world
Use one photo or concept still as visual reference. Panoramas (≥2:1) can stand alone as the sole media input.
Video to 3D world
Upload one short clip (MP4 / MOV / WebM, up to 30s and 100MB) to guide structure and motion cues.
How to create a 3D world
Three input paths. One Canvas workflow.
01
Open 3D World in Canvas
From the Creation sidebar or right-click menu, open the 3D World dock on your Infinite Canvas.
02
Add text, an image, or a video
Describe the scene, upload one image, or upload one video up to 30 seconds. Pick Marble 1.1 or Marble 1.1 Plus, then generate.
03
Enter, explore, and capture
When the card succeeds, enter full-screen exploration, move with WASD and mouse look, then screenshot the framing you want back onto the canvas.
What is a Gaussian Splat world?
A Gaussian Splat represents a scene as millions of tiny ellipsoids instead of a traditional polygon mesh. That makes free camera movement and view capture feel natural. Topview uses this format so you can explore the generated world and pull stills into your Canvas pipeline — it is not the same as an image-to-3D-model tool that exports GLB or STL.
What creators use 3D worlds for
Environment concepting
Block out locations for storyboards, ads, and film-style sequences before committing to final plates.
Product and brand spaces
Build branded rooms or outdoor sets, then capture hero angles for image and video campaigns.
Shot planning from inside the scene
Walk the space, lock FOV and aspect ratio, and send screenshots into image or video generation next.
