Q1. Imagine that you are using a software a tool to create a 3d architectural scene. When you first start work on the scene, it always opens after just a couple of seconds and shows all objects, lights, and textures. However, after working on it for some weeks, adding additional objects to the scene, it now takes several seconds to load, and objects initially appear some random shade of color. Although you are allowed to interact with the scene, only later do the objects become textured.
