An animated horse 3D model typically includes detailed anatomy, realistic textures, and smooth animations. These models are often rigged for movement, allowing for lifelike actions such as walking, running, jumping, or grazing. High-quality models may feature advanced details like muscle movement and fur simulation, while low-poly versions are optimized for performance in games or virtual reality. They are widely used in projects like films, games, and simulations to bring a sense of realism and dynamism to scenes.
