Modeling and texturing a photorealistic fishA Lightwave Tutorial
In this tutorial we're going to do things a little differently then you may be used to. Because our goal is to model and texture a realistic fish, we're going to start with the texture map as the basis for building our model. Please note that although I'm partial to LightWave, this tutorial is applicable to any 3d application that supports images in the modeler viewport. Please feel free to download the images on this page and follow along.
1. I started out by scanning a photo of a fish on a flatbed scanner (figure 1), this had to be separated from the background and retouched with paint and clone tools in Photoshop. The gamma curves were also adjusted to provide a sharp and saturated image which will become the color map for our fish. Name this image color_map and save it. You may also use a real fish as a basis for your texture, although you may have to fillet it to make sure it lays flat on the scanner. There are a couple of advantages to this method, 1. it will provide you with the sharpest, most authentic texture, and 2. when your boss sees you filleting a fish on your office desk and gingerly slapping it on a scanner he'll think you're in bad need of a break and give you the week off.
2. In photoshop, turn the full-color scan into a grayscale image, and boost the contrast to get a nice definition between the dark and light tones. This image (figure 2) will be used as a template to model the fish, as well as a texture map to control diffusion. Name it gray_map and save.
