What is 3D Modeling?
3D modeling is the process of creating three-dimensional representations of objects using specialized software. Unlike 2D images which only have width and height, 3D models have width, height, and depth.
How 3D Models Work
A 3D model is made up of:
- Vertices - Points in 3D space (X, Y, Z coordinates)
- Edges - Lines connecting vertices
- Faces - Flat surfaces bounded by edges
Together, these form a mesh - the wireframe structure of any 3D object.
> [!INFO] > Think of a mesh like a digital wireframe sculpture - the more vertices and faces, the smoother and more detailed the model!
Why Learn 3D Modeling?
3D modeling skills are valuable in many industries:
| Industry | Applications |
|---|---|
| Gaming | Characters, environments, props |
| Film/Animation | VFX, animated movies |
| Architecture | Building visualization |
| Product Design | Prototypes, packaging |
| 3D Printing | Physical object creation |
| Web/AR/VR | Interactive experiences |
What You'll Create
In this course, you'll learn to:
- Navigate 3D space
- Create basic shapes (primitives)
- Transform objects (move, rotate, scale)
- Apply materials and colors
- Export models for web and 3D printing
> [!TIP] > No artistic experience is needed! 3D modeling is about understanding shapes and space - skills anyone can learn.
