The creation of 3D models and animations is primarily enabled by technologies like computer graphics and 3D modeling software. Software such as Autodesk Maya, Blender, and Cinema 4D allows artists and designers to create complex, visually stunning designs. These tools provide features like polygon modeling, texture mapping, and animation rigging. Moreover, advancements in virtual reality (VR) and augmented reality (AR) further enhance these technologies, enabling immersive experiences. The integration of physics engines also allows for realistic interactions and movements within these environments.
