Some of the most widely used software includes:
- Autodesk Maya: Known for its robust features in animation, modeling, and rendering, Maya is a preferred tool in the film and gaming industries.
- Blender: A free and open-source tool, Blender offers a comprehensive suite of modeling, texturing, rigging, animation, and rendering tools. It's popular among indie developers and small studios.
- ZBrush: Renowned for its advanced sculpting tools, ZBrush is used to create highly detailed models, especially characters and creatures.
- 3ds Max: Another Autodesk product, 3ds Max is widely used in game development, architectural visualization, and industrial design.

3D modeling involves various techniques to create and refine models. Some of the common techniques include:
- Polygonal Modeling: This technique involves creating models using polygons, which are flat shapes with multiple sides. Polygonal modeling is suitable for creating detailed and complex surfaces.
- NURBS Modeling: Non-Uniform Rational B-Splines (NURBS) are used for creating smooth and mathematically precise surfaces. This technique is often used in automotive and product design.
- Sculpting: Digital sculpting allows artists to manipulate a model as if it were clay, adding intricate details and organic shapes. ZBrush and Blender are popular tools for digital sculpting.
- Procedural Modeling: This technique uses algorithms to automatically generate complex structures and patterns. It is often used in creating natural environments, like forests and terrains, in a more efficient way.
