Pre-rendering is done before the construction process begins to help clients understand the design idea and the building details effectively and easily. Real-time rendering is done once the first rendering is processed completely to change and further beautify the existing designs, effects and textures.

Rendering images is important for a project because it brings 3D models to life, offering a realistic and comprehensive visualization of a design before it is built or produced. This enhances communication between designers and clients, enables better decision-making, facilitates marketing, reduces costs associated with physical prototypes, and allows for easy design modifications.
