3D in Photoshop: The Ultimate Guide for Creative Professionals

Mensagem por IuriMonteiro em Qua Fev 23, 2011 9:47 pm

With the introduction of 3D capabilities starting in CS3, concept artists had the potential to introduce 3D models into their concept scene. It was best at that stage of development to texture the 3D model in its native program and allow Photoshop to simply read what was already created. Then CS4 came along which made some great improvements in how well it handled 3D geometry. Its ability to use its painting tools directly on the 3D object was a feature that artists greatly appreciated, but even then there were limitations.

Now we are going to explore what are, in my humble opinion, some great improvements in CS5’s 3D texturing engine.

Texturing infuses character into the 3D object to bring out the personality needed to tell a story. Without this your object is naked and lifeless. Texturing is an art within itself and some artists will specialize in just that. A great amount of time can be invested into this e days or weeks depending on the demands of the creative director.

Real-life objects absorb light to some degree and what we see is the results after absorption. If you look at objects around you, whether they are fabric, water, leaves or even a mountainous landscape, it is important to break down what we are seeing into their surface types. Basically, 3D programs identify and manipulate objects as several surface types by breaking them up into materials. For more information on materials, see Chapters 1 and 4.

Keep in mind that this chapter is written for the artist who has little or no knowledge of 3D creation; however there is the desire to add 3D content to their workflows, to introduce eye-catching effects as well as greater flexibility with their designs. We will accomplish this through the use of an online database that will provide quite a bit of the 3D content that we can use for our personal projects. Although we will provide a few companies for you to consider, we will focus on one online company that has created a plugin for CS5 that will import 3D objects directly into the 3D layers. The company is 3DVIA (www.3dvia.com).

We are going to illustrate a common compositing concept in this chapter. We will import a concept car from 3DVIA to use as the main character in our scene. We will illustrate it by showing it speeding through the wet streets of a downtown area of a city block that we will also download through 3DVIA database.

Note: This tutorial requires some basic knowledge of Photoshop tools such as the Clone Stamp, Transform, Various Shape Tools, Gradients and more. If you are not familiar with these tools, you should first learn these before proceeding.

Ok, let's start creating!
