What is Gaussian Splatting (and how does it work)?

Gaussian Splatting is a 3D rendering technique that represents a scene as millions of colored, transparent particles. While excellent for viewing, it does not produce a usable geometric mesh. Neural4D is an alternative that reconstructs scenes directly into watertight polygonal meshes (like .glb or .fbx), making them instantly ready for gaming or 3D printing.

What makes Neural4D's text to 3D better than other AI tools?

Neural4D uses the Direct3D-S2 engine with Spatial Sparse Attention (SSA). SSA focuses computational resources on critical geometric features and semantic transitions simultaneously. This ensures complex parts like joints, organic details, and thin features are watertight and structurally sound, rather than hallucinated.

What file formats can I export for professional use?

You can export industry-standard formats including .obj, .fbx, .glb, and .usdz for high-fidelity rendering, as well as .stl for 3D printing. For supported formats, Neural4D provides a complete PBR texture set (Normal, Metallic, Roughness) to ensure seamless integration into professional pipelines.

Can I sell 3D models I generate with Neural4D?

Yes, paid subscribers retain 100% commercial ownership of all generated assets. Free users receive 50 power per week for personal, non-commercial exploration.

How long does it take to generate a 3D model from text?

Neural4D generates production-ready models in approximately 90 seconds. We utilize global GPU clusters to ensure consistent speed for users in any region.

Neural4D-2o is the first true Conversational 3D Engine. Stop rolling the dice with random text-to-3D prompts. Generate, edit, and refine production-ready 3D meshes iteratively through natural language dialogue.

Conversational 3D Capabilities

Why conversational? Traditional AI 3D generators give you a single shot. If the sword is too short, you have to start over. Neural4D-2o remembers your context and allows you to iteratively modify the 3D geometry and materials just by chatting.

Iterative Prompting

Chat with the engine to modify specific parts of your model. Ask to "make the sword longer" or "change the armor to sci-fi style" without losing your base mesh.

Contextual Awareness

Neural4D-2o remembers your previous prompts. It understands the history of your design, allowing for complex, multi-step 3D modeling workflows.

Multi-Modal Reasoning

Neural4D-2o understands both text instructions and visual references simultaneously. Upload a sketch and use conversation to fine-tune the resulting 3D geometry seamlessly.

A New Paradigm in 3D Creation

Refine characters dynamically for game development

Dynamic Asset Refinement

Game developers can tweak asset proportions interactively. Tell Neural4D-2o to "scale down the character's shoulders by 10%" and get immediate tri-mesh updates.

Conversational Geometry Fixes

If a generated model has a thin part that will break during 3D printing, simply chat: "thicken the base to ensure it's printable" and receive a fixed STL file.

Interactive PBR Texturing

Change textures on the fly. You can type "make the wooden texture look more weathered and metallic" and Neural4D-2o will swap out the PBR maps seamlessly.

Rapid Ideation

Product designers can brainstorm in 3D. Start with a basic shape and iteratively chat your way to a highly detailed, complex polygonal structure.

How Conversational 3D Works

1. Generate the Base Mesh

Start the conversation with a simple text prompt or image upload. Neural4D-2o will instantly generate a high-quality triangular mesh as your starting point.

Chatting with Neural4D-2o to edit the mesh

2. Chat to Refine & Edit

Don't start over if it's not perfect. Type instructions into the chat like "add spikes to the armor" or "make it red". The AI understands your intent and modifies the existing mesh.

3. Export Tri-Faces to Any Engine

Once the conversation has led to the perfect model, export your watertight triangular mesh directly to .FBX, .GLB, or .STL for immediate use in Unreal, Unity, or your slicer.

Conversational 3D FAQs

What is Conversational 3D Generation?

Conversational 3D Generation is a new AI workflow where you use a chat interface to iteratively build and modify a 3D model. Instead of relying on a single text prompt, you converse with the AI engine to refine shapes, colors, and geometry step-by-step.

What kind of topology does Neural4D-2o generate?

Neural4D-2o generates highly optimized triangular meshes (tri-faces). These watertight tri-meshes are perfect for 3D printing and are natively supported by all major game engines like Unity and Unreal Engine 5.

Can it remember my previous edits?

Yes. Neural4D-2o features contextual awareness. If you tell it to "change the color to blue" and then "make the handle longer", it will execute both edits without forgetting the context of your previous chat messages.

Is it available in the standard API?

The conversational state management is currently available through our Studio interface. API support for conversational sessions will be available in the upcoming v2.0 endpoint release.
