AI‑Driven 3D Content Creation and Optimization for E‑commerce

3D models bring plasticity and editability to intelligent design, extending the limits of 2D design, but they face clear constraints: modeling efficiency, model quantity, and 3D design cost.

In product display, the importance of matching people‑goods‑scene is evident. With the rise of 3D, VR and other new media, beyond traditional images and short videos, 3D model‑based content creation is becoming a key format.

From the user side, consumers consider color, style, functionality and comfort when buying large furniture. From the seller side, 3D content creation improves efficiency, e.g., phone manufacturers use 3D models for short videos with dynamic backgrounds for different SKUs.

The workflow is divided into three core steps:

Creation : generate diverse content from 3D models, 2D images or text.

Delivery : deploy the content as product hero images or short videos.

Optimization : use online traffic feedback to refine 3D content through atomic design elements.

Current bottlenecks include high demand for quality assets, lack of historical data for 3D/AR/VR formats, copyright risks, and high professional production costs.

Our solution introduces:

Creative background generation (txt2img) and AI‑style transfer (img2img) to boost efficiency and user experience.

Diffusion model fundamentals (DDPM, DDIM) and sampling optimizations that reduce computational load while preserving quality.

Shapley‑value based feature importance (with sampling‑based approximation) for design interpretability.

A multi‑level traffic amplification framework comprising cold‑start modeling, flow‑control, and design‑feedback loops.

Algorithmic details: DDPM assumes small Gaussian noise per step; DDIM derives an iterative formula that maintains Gaussian reversibility, drastically cutting sampling steps. Further Taylor‑expansion of the integral form yields second‑order approximations that further reduce sampling requirements.

We also build a unified 2D/3D feature system (pose, camera parameters) to enable pairwise loss functions that guide design decisions.

Future work will continue to expand 3D content efficiency and experience, leveraging the described techniques to push the boundaries of AI‑generated visual commerce.
