Tài iệu Photoshop cs5 by Dayley part 103

Một lần nữa bạn có cơ hội để nâng cao chất lượng vẽ của bạn bằng cách hy sinh thời gian xử lý. Tùy chọn này được thiết lập theo mặc định để làm cho đối tượng 3D của bạn trong chế độ (sơn) để tương tác khi bạn thao tác và chỉnh sửa đối tượng của bạn, bạn đang làm việc với họ trong thời gian thực chứ không phải chờ đợi sau mỗi lần di chuyển cho đối tượng của bạn phải được tái kết xuất | Chapter 23 Using the 3D Panel to Edit 3D Scenes and Settings Quality Again you are given the opportunity to improve the quality of your rendering by sacrificing processing time. This option is set by default to render your 3D object in Interactive painting mode so that as you manipulate and edit your objects you are working with them in real time rather than waiting after each move for your object to be re-rendered. When you are finished creating manipulating and adding texture to your object you want the final draft to be rendered in the highest quality possible. At this point choose Ray Traced Final Draft from the Quality drop-down menu. This process takes several minutes at best so be sure you are ready to complete the final rendering. Paint On The Paint On option allows you to choose a texture to use to paint on using the 3D paint mode. If you choose a texture that has not been created for your object Photoshop creates it for you. Painting on these textures doesn t actually leave painted pixels behind it just makes changes to the texture. When you paint on a glossy texture for instance you make changes to the glossiness of your 3D object. Global Ambient Color Double-click the Global Ambient Color swatch to change the color of the reflective surfaces in your 3D scene. This light doesn t cast any direct light or shadows but it can add a cool or warm tone to your scene. Creating cross sections Creating a cross section is another very versatile option found in the scene settings within the 3D panel. A cross section is created by cutting into a 3D object and looking into it. Cross sections have several varied uses. Cross sections are great for use with architectural renderings. A cross section allows you to see inside the models of 3D buildings. You can see in Figure 23.9 that I cut the roof off this simple room to show you the inside of it. You can see that this could be a very valuable application for looking at or editing more complex buildings or furnished .
