3D Modeling Services
3D modeling is the backbone of every CGI workflow. It covers all types of product rendering, animation, configurators, AR, and VR. No matter how advanced the final result looks, everything starts with a clean, accurate, well-optimized 3D model. If the model is incorrect, even the most advanced lighting, materials, or animation will fail to look realistic.
A professional 3D model can be built from almost any input: photographs, CAD drawings, technical blueprints, video references, 360° walkarounds, or even 3D scans. What matters is translating these sources into geometry that meets the needs of rendering or real-time engines.
Just as importantly, models for photorealistic rendering and models for real-time interaction (AR/VR/web) are two very different categories.
• Rendering models prioritize micro-details and realism. • Real-time models prioritize polygon efficiency and speed.
This guide explains all major modeling types, categories, complexity levels, reference requirements, outputs, software, and the complete workflow used at CGIFurniture.
Types of 3D Modeling
Below are the essential modeling types used in product visualization, along with examples, applications, and key benefits.

Levels of Modeling Complexity
Below is a clear breakdown of the four main levels of furniture 3D modeling, based on CGIFurniture’s internal standards. Understanding these categories will help you identify the right model type for your product and plan your CGI budget more accurately.
1. Simple Models

What they are: Simple models feature minimal geometry and very few details. They are built from basic shapes such as cubes, spheres, cylinders, and work perfectly for straightforward furniture items such as basic chairs, tables, benches, or simple shelving.
Characteristics:
- No seams, stitches, or fittings
- No complex texturing
- Often created from ready-made geometry and standard texture maps
- Fastest and easiest to produce
- Typical production time: ~1 working day
- Price range: ~$40–$60
- When to choose this level: For minimalist products with clean geometry and no ornamental elements. Ideal for quick prototyping or basic catalog imagery.
2. Medium Complexity Models

What they are: Medium-level models include furniture with slightly more nuanced geometry — still fairly simple, but featuring more components and visible details.
Examples: Sideboards, bedside tables, TV consoles, chests of drawers, and similar cabinet pieces.
Characteristics:
- Moderate amount of decorative elements
- Simple fittings
- Common and uncomplicated textures
- Suitable for minimalistic or modern designs
- Typical production time: ~1 working day
- Price range: ~$80–$120
- When to choose this level: For furniture with clean lines but a bit more structural complexity. Perfect for most catalog-ready models.
3. Complex Models

What they are: This tier covers furniture that requires intricate geometry, rich textures, and precise detailing.
Examples: Chesterfield sofas, upholstered armchairs, refined cabinetry, or furniture made of premium materials.
Characteristics:
- Detailed stitching, quilting, and fittings
- Challenging textures (leather, silk, unique woods, stone patterns)
- May require retopology in 3ds Max to optimize geometry for smooth performance
- Suitable for real-time rendering, AR/VR, configurators, and 360° viewers (if requested)
- Typical production time: ~2 working days
- Price range: ~$140–$200 When to choose this level: When the product has elaborate detailing or when the 3D model needs to be optimized for interactive digital experiences.
4. Highly Complex Models

What they are: The top tier is used for furniture sets, multi-element compositions, or designs with extreme levels of sophistication.
Examples: Intricate furniture collections, items with carving, weaving, ornate materials, or many small components.
Characteristics:
- Large number of individual parts
- Extensive custom texturing and material creation
- Often requires retopology
- Each element is built with a fully customized approach
- Most time-consuming and detail-heavy modeling process
- Typical production time: ~2 working days (sometimes more, depending on set size)
- Price range: ~$220–$400
- When to choose this level: For luxury furniture brands, high-end marketing, or any product where visual realism and material accuracy are critical.
Factors Affecting Complexity
- Availability of CAD files or dimensions — the more accurate the references, the faster the workflow.
- Reference gaps — missing angles or low-quality photos increase complexity.
- Rigging requirements — hinges, openings, sliding parts, mechanisms.
- Material complexity — intricate textures, fabrics, patterns.
Reference Requirements
To create an accurate model, ideal references include:
- 360° video walkarounds
- Exact dimensions (height, width, depth)
- Close-ups of materials and details
- Finish options (colorways, hardware variations)
- Technical drawings or CAD if available
Accurate data reduces revisions and ensures scale precision.
