Model optimization

Definition

Model optimization is the process of improving a 3D model by reducing its complexity while maintaining visual fidelity and accuracy. This involves techniques that balance polygon count and texture resolution to enhance performance in rendering and usability in various applications, including gaming and installation art. An optimized model not only performs better but also loads faster, making it essential for real-time applications.
