Advanced 3D Photorealism Techniques by Bill Fleming

By Bill Fleming

This e-book, like Bill's previous one, bargains commonly with detailing of versions (geometry) merely. It doesn't talk about fabrics extensive, or lights, worldwide Illumination and so forth. So a wide a part of what makes scenes photrealistic isn't touched upon. extra importantly, his geometry detailing options will doubtless upload a few zillion polygons. No dialogue on that both- no scheme is gifted to maintain a count number of polygons, or preserve them inside good limits.
Without right lights and fabrics, invoice doesn't rather produce photorealistic results.
The description of imaginary worlds and creatures is unimaginative and tedious.
The underlying ideas are noteworthy, yet should be summarised in a single web page- which i believe invoice *has* performed: it is there someplace on the internet.

This is the most important element of natural 3D images. The tiny specular highlights on the bumps bring the surface to life. Let’s face it, a smooth, dull worm would be less than realistic. Ditto for leaves, bark, and even rocks. Yes rocks. While they aren’t typically wet, they do have tiny crystals that reflect light, which is particularly evident in granite. Objects don’t need to be alive to be specular. Let’s take a look at how specularity impacts the photorealism in the Goblin toilet image.

The problem areas. In this case; you’ll want to use a clone tool with the opacity set to 100 percent to remove the reflection of the photographer. You’ll also need to be careful not to clone over the cracks in the glass. These are great details that shouldn’t be removed. To avoid erasing the cracks, use a smaller brush, which will give you more control. 15. 13. Now for the disaster area. The upper right windowpane is a mess. You’ll need to remove some reflections and the caulking while keeping the cracks intact.

There isn’t much in the way of enamel paints and metals in the wilderness, so the amount of reflected light is dramatically reduced. Of course, there are still a number of objects and surfaces that do reflect light in nature, such as water, rocks, ice, mud, or any wet or crystalline object. Have you ever noticed that everything is completely illuminated on the water or in snow-covered environments? That’s because the light is being reflected by the wet specular surfaces. You’ll find that things are much brighter after it rains because moisture is covering eve g, making all objects reflect light.
