Fundamental Understanding: Comprehending the Nature of AI 3D Generation

How AI Generation Works

AI 3D generation is essentially a mapping process from text or images to three-dimensional geometry. Understanding this helps us optimize inputs for better outputs. TRELLIS models used by platforms like Open3D.art are trained on massive 3D datasets, enabling them to understand object shapes, materials, proportions, and other characteristics.

Input Quality Determines Output Quality

Like the traditional "garbage in, garbage out" principle, AI generation quality largely depends on your input quality. A carefully designed prompt or high-quality reference image can often bring results exceeding expectations.

Prompt Engineering: Core Skills for AI Generation

Basic Prompt Structure

Effective prompts should follow this structure:

```

[Main Object] + [Style Description] + [Material Information] + [Size Constraints] + [Usage Description] + [Technical Requirements]

```

Example Comparison:

Keyword Weight Distribution

In prompts, words appearing earlier carry higher weight. Place the most important features first:

Correct Order:

1. Object type (most important)

2. Style characteristics (core)

3. Material properties (important)

4. Functional features (supplementary)

5. Technical requirements (constraints)

Style Consistency Keywords

To achieve stylistically unified model series, establish standard style keyword libraries:

Modern Minimalist: modern, minimalist, minimal, geometric, clean lines

Industrial Style: industrial, metal, raw, rough, mechanical feel

Nordic Style: Nordic, natural, cozy, wooden, simple

Sci-Fi Style: sci-fi, futuristic, high-tech, glowing, metallic texture

Image Preprocessing Tips

Use simple image editing tools for preprocessing:

1. Background Removal: Use tools like remove.bg

2. Brightness Adjustment: Ensure object clarity

3. Contrast Enhancement: Highlight object contours

4. Size Optimization: Recommend 1024x1024 pixels

Quality Control and Optimization Workflow

Necessary Post-Generation Checks

Conduct systematic checks after each generation:

Iterative Optimization Strategy

Don't expect perfection in one generation; establish iterative optimization workflow:

1. Rapidly Generate Multiple Versions: Generate 3-5 different versions at once

2. Select Best Foundation: Choose the version best meeting requirements

3. Targeted Improvements: Adjust prompts based on problems

4. Detail Optimization: Use professional software for final adjustments
