3D modeling programs are software applications that allow users to create three-dimensional representations of objects or scenes. These programs enable artists, designers, and engineers to build digital models that can be manipulated and viewed from various angles. Common features include tools for shaping, texturing, and rendering, which help bring the models to life. Popular examples of 3D modeling programs include Blender, Autodesk Maya, and SketchUp. These tools are used in various industries, such as video game development, animation, architecture, and product design. They facilitate the visualization of concepts and enhance creativity in the design process.
