该资源是一本专门针对3D游戏贴图创作的专业指南，利用Adobe Photoshop这一强大的图像编辑软件来提升游戏艺术的品质。作者Luke Ahearn是该领域的专家，由知名出版商Focal Press（Elsevier的副品牌）出版。这本书涵盖了3D游戏纹理设计的各个方面，旨在帮助读者从新手成长为专业游戏艺术家。
在书中，你将学习到如何通过Photoshop创作出逼真的3D游戏纹理，包括但不限于以下关键知识点：
1. **纹理基础**：了解纹理在3D游戏中的重要性，以及它们如何影响游戏世界的视觉效果。理解不同类型的纹理，如颜色贴图、法线贴图、置换贴图、镜面贴图等，以及它们各自的作用。
2. **Photoshop工具和技术**：深入掌握Photoshop的工具和功能，如选择工具、画笔工具、克隆图章、滤镜、图层混合模式等，这些都是制作高质量3D游戏纹理的关键。
3. **纹理绘制**：学习如何绘制和编辑纹理，包括色彩理论、纹理细节的添加、纹理的无缝拼接等技巧。
4. **摄影纹理采样**：了解如何从现实世界中获取灵感，使用照片作为参考进行纹理创作，以及如何处理和编辑这些照片以适应游戏环境。
5. **UV映射**：学习如何在3D模型上合理分配纹理，理解UV坐标和展开技术，确保纹理在3D模型上的正确显示。
6. **工作流程和效率**：探讨高效的工作流程，如何组织项目文件，以及使用Photoshop脚本和动作提高工作效率。
7. **后期处理和优化**：学习如何对纹理进行最后的润色，以及如何优化纹理以减少游戏性能的影响，保持游戏流畅运行。
8. **案例研究**：书中可能包含实际的游戏项目案例，分析这些项目中的纹理设计决策和创作过程，提供实践指导。
9. **版权和许可**：了解关于复制、存储和传输作品的版权法规，以及如何获得使用他人素材的授权。
通过这本全面的教程，读者不仅能够掌握3D游戏纹理的制作技术，还能了解到与之相关的法律和行业规范，从而在游戏艺术领域建立起坚实的基础。无论你是游戏开发新手还是寻求提升的专业人士，这本书都是一份宝贵的参考资料。
Five: The Sci-fi Setting
This is the first tutorial chapter. The sci-fi scene looks complex due
to the geometry and effects present, but in actuality the texture set
is very simple. We will start by taking from the concept sketch ideas
for the base materials we will create for the scene and from that
base build a simple and versatile set of textures. This method
produces textures that can be used in various ways and are
designed to be used with the newer technology coming out
(shaders like bump and normal mapping, etc.).
Six: The Urban Setting
In this chapter we will learn to work more faithfully to the detail in a
concept sketch or any reference material that may be given to us.
When you create textures for a game environment, you are usually
creating them for a world that has been thought out, detailed, and
developed to the point that showcasing your creativity is not the
primary goal of your work. You are showcasing your talent and
ability to recreate what you see in the materials in front of you. We
will build a set of textures as they were traditionally created, in sets:
base, wall, floor, and ceiling. This chapter focuses on breaking out
not only the base materials that need to be created for a scene,
but also the detail textures as well. Even though this approach is
falling by the wayside due to technological advances, it is still an
applicable skill to many games and applications and a good skill to
have when you are required to work with more advanced
technology. We always start with the basics to build a material
(shape, color, texture) and build detail on top of that. What you end
up with is a full texture set that is easily altered and built upon.
By the end of the chapter you will have created all the textures
needed for the urban environment as seen in the concept sketch.
Seven: The Fantasy Setting
This is a long chapter, so be ready to pace yourself. This chapter
combines the creation of many high-detail textures that are used in
a high polygon-count scene. We will use the Path Tool in Photoshop
to create the fancy curves you see in the scene, and we will do some
basic hand painting that will produce great results. Finally, we will
look at the process of creating the textures used in a shader.
Eight: The Outdoor Setting
In this chapter we will create a set of textures for a forest that can
be altered to look spooky, friendly, or fanciful. Using the basic
approach presented here to break out the elements of an outdoor
scene, you can also create a similar set of textures for any outdoor
environment; jungle, desert, etc. I will also introduce the use of
photo source in texture creation. I mentioned in the very beginning
of the book that the use of photo source to create textures is not
