3D / AI Dictionary

Hard 3D and AI terms, each explained in 2 simple lines.

What is the 3D / AI Dictionary?

The 3D / AI Dictionary is a free, searchable glossary for beginners in 3D rendering and AI art. It explains terms like GI, HDRI, denoiser, seed, prompt and inpainting in two short, plain-English lines each. Type a word to find it fast, then try the related tools to see the term in action.

Render

Turning a 3D scene into a final image or video on the computer.

V-Ray

The render engine for 3ds Max that calculates light the way it works in the real world.

Global Illumination (GI)

Light bouncing off walls and objects and spreading through the whole room.

HDRI

A 360° photo that gives the scene real lighting and reflections.

Noise

Grainy dots in a render, caused by low sampling.

Denoiser

A tool that cleans up render noise using AI or math.

Exposure

A camera setting for how bright or dark the image is.

Texture

An image applied to a surface, like a wood or marble pattern.

UV Mapping

The way a texture is laid out correctly on a 3D model.

Bump / Normal Map

An image that shows small surface detail (roughness) without changing the model.

Polygon

The small flat pieces that make up the shape of a 3D model.

Subdivision

Adding more polygons to make a model smoother.

Depth of Field

The object in focus stays sharp and the background is blurred.

Frame Buffer (VFB)

The V-Ray window where the render appears and you correct the color.

Prompt

The written instruction you give an AI about what to make.

Seed

The number behind an AI image. The same seed gives a similar result again.

Aspect Ratio

The ratio of an image’s width to its height, like 16:9 or 9:16.

Upscale

Making a small image bigger and more detailed.

Inpainting

Using AI to change only one part of an image.

Text-to-Video

Making a video with AI by typing what you want.

How to use this dictionary

  1. Type a word in the search box at the top, like noise, HDRI or seed.
  2. The list filters as you type and shows only the matching terms.
  3. Read the short meaning. Each term is explained in plain words, without heavy theory.
  4. Clear the search box to see every term again.

How to learn these terms faster

Do not try to memorize the whole list. Learn a term when you meet it in real work. If your render is grainy, read Noise and Denoiser, then try the fix. If an AI image keeps changing, read Seed and Prompt. Using a word once in a real project teaches more than reading it ten times.

The terms cover two worlds: 3D rendering in 3ds Max and V-Ray, and AI image and video tools. Many ideas overlap. Light, exposure and aspect ratio matter in both.

Terms by topic

  • Lighting: Global Illumination, HDRI, Exposure.
  • Image quality: Noise, Denoiser, Upscale, Depth of Field.
  • Models and surfaces: Polygon, Subdivision, Texture, UV Mapping, Bump / Normal Map.

Questions people ask

I am a complete beginner. Where should I start?

Start with Render, Texture, Exposure and Prompt. These four words explain most of what happens in a 3D or AI project.

Will you add more terms?

Yes, terms will be added when they come up in my tutorials and tools.

Is there a tool to fix the problems in this list?

Yes. Render Doctor shows the cause and the fix for common render problems like noise, dark rooms and burned highlights.
