3D modeling and 3D rendering are two stages of CGI creation. Businesses request images from 3D artists for a variety of purposes. For example, to showcase products for sale or create visuals of renovated hotel rooms before the renovation is finished. The first step is to create 3D models or meshes of the room and each item in the room. Next, the artist designs a realistic material or texture for each item such as a marble countertop or chrome faucet. Each is painstakingly colored and textured to look just like the real thing. At this point, the second stage of CGI creation takes place.

At this stage, also called visualization, the 3D artist arranges the models in a three-dimensional space and customizes lighting using scientific calculations – this is where having a background in physics is very helpful and why our 3D artist stands apart from most with his background. Simulations for creating water also use physics and incorporating this knowledge can mean the difference between water that looks static or plastic and water that looks real. It’s now time to render the image which results in a series of passes covering direct and indirect lighting, gloss, and ambient occlusion, then composite all passes to make a final image.

When done well, a 3D artist’s image is indistinguishable from a photo, making it an economical alternative to expensive on-site photo shoots.
