What is the application of shade in an architectural rendering?

In architectural rendering, shade is used to enhance realism by simulating how light interacts with surfaces and structures. It helps to define form, depth, and texture, making elements appear more three-dimensional. Additionally, effective shading can highlight design features and create a mood or atmosphere, guiding the viewer's attention and emphasizing spatial relationships within the design. Ultimately, it contributes to a more convincing and visually appealing representation of the proposed architecture.
