Nhấp vào hộp kiểm tra mượt mà để chuyển vào làm mịn. Trong 2,12 hình, bề mặt của quả cầu xuất hiện mượt mà hơn, mặc dù bạn có thể phát hiện faceting, đặc biệt là xung quanh chu vi của đối tượng. | T2. I chapter 2 introducing 3Ds max objects 2. Click the Wireframe label in the upper-left corner of the viewport and select Smooth Highlights from the context menu. Figure clearly shows the faceting because sphere s Smooth parameter overrides the viewport s Smooth Highlights rendering mode. 3. Click the Smooth check box to turn on smoothing. In Figure the sphere s surface appears smoother although you can detect the faceting especially around the perimeter of the object. 4. Click and drag the Segments spinner down so that the Segments value reads 4 the lowest possible value for a sphere. Figure shows that the sphere becomes a pyramid shape with the edges smoothed. FIGURE The sphere after changing the viewport rendering mode FIGURE The sphere after smoothing is turned back on FIGURE The smoothed sphere after the number of segments is lowered to four understanding standard primitives 73 5. Click the Smooth check box again to turn off smoothing. The sphere now looks like a pyramid with flat surfaces see Figure . FIGURE The sphere after Smoothing is turned off Smoothing provides the illusion of a gradual curve hiding the facets that are required to construct objects. In the extreme case where a sphere is reduced to four sides smoothing still provides the illusion of a smooth edge but it does not hide the sharp corners along the profile of the sphere s geometry. In situations where you need to show a smooth curved surface the Smooth parameter is essential. You can apply smoothing to all objects even if they do not have a Smooth parameter by default. You ll learn more about applying smoothing to objects in later chapters. Accessing Parameters Immediately after you create an object you can set its parameters on the Create tab of the Command panel. However if you create several objects and then decide you want to modify the parameters of an object you created earlier you ll need to use the Modify tab of the Command panel. 1. Click .
