3D Modeling is a complex process of creating a mathematical representation of three-dimensional surfaces and objects, commonly used in fields like game design, animation, and virtual reality. Coursera's 3D Modeling catalogue teaches you the fundamental concepts and techniques required to create, modify, and render 3D models. You'll learn how to use different modeling tools, understand the importance of topology and geometry in 3D space, apply textures and materials, light your scenes, and render the final product. You'll also gain a deeper understanding of industry-standard software like Blender, Maya, and 3DS Max, helping you to create visually stunning and realistic 3D models for various applications.
