A 3D walkthrough is a technology that allows the users to view the interiors of buildings and plans of constructions. The homebuyers can get a vivid interpretation of the construction along with all the details with virtual house walkthrough.
Many 2D animations attempt to give the reality of a 3D world. When we talk about 3D animation, we usually refer to animations that were created by moving a camera around a three-dimensional object to give a perfect representation of the model. For certain applications, rendering something in a 3D world saves a lot of time.
Let’s say we want to animate a molecule of water by having the molecule spin. Animating this in a 2D space would require us to create images for every frame of the spin then cycle those images together to create the illusion of a 3D environment. With a 3D editing program, we simply model three spheres into the shape of a water molecule, and tell the molecules to spin for any length of time we desire. The computer renders the in-between images perfectly.
