What is the need of fractals in computer graphics?

Fractals are essential in computer graphics for creating complex and realistic patterns that mimic natural phenomena, such as mountains, clouds, and Coastlines. Their self-similar nature allows for the generation of intricate details at various scales without requiring immense amounts of data. Additionally, fractals contribute to efficient rendering techniques, enabling dynamic environments and textures that enhance visual realism while optimizing performance. Overall, they are a powerful tool for artists and developers in producing visually captivating graphics.
