As we all know, in the three-dimensional relief effect simulation software, in particular to make models of relief is a very difficult. This paper introduces examples of ways in 3DS MAX Fine relief model in the production of specific methods and procedures. Learn this method to deal with relief in the MAX effect becomes very easy. MAX This tutorial has some basis for the readers.
Made in 3DS MAX the lifelike sculpture, especially relief effect, not so easy. Front of the Tiananmen Square (see below) is a typical example.
If made by hand modeling, even if the technology no matter how high, time would need a month or two, but can not guarantee results. In general we may think of carving effect, it identified with DISPLACE (displacement) modifier, or material in use DISPLACEMENT map with NURBS. However, results obtained in this way is very rough, difficult to accept. The author after a long period of exploration, and finally summed up a viable, efficient way, willing to share with friends.
1) Run 3DS MAX. Requirements 3DS MAX R3 above. I use the 3DS MAX 4.2.
2) Switch to Front View. Tap CREATE PANEL / GEOMETRY / PATCH GRIDS (Create Panel / geometry / patches) in the former view, creating a surface film (QUAD PATCH), 600 units in length, a width of 500 units. In fact the specific ratio required to be the best. Also we must remember to PATCH the length and width segments from the default of 1 to 6 and 5, in order to increase the complexity of the object. Shown in Figure 1.

5) The method to do the first secret is that relief displacement mapping on. Open the Material Editor, select the first sample of material, the material name from the default value to "displacement mapping" the diffuse reflection color (DIFFUSE) into your favorite color. MAP shutter opens, find DISPLACEMENT (displacement) map slot. Tap the map slot (above "NONE" word), pop-up material / map browser. In the right window, select "BITMAP" (bitmap) taken after the point of "OK" button, will pop up a dialog box select the bitmap file. Please choose me for grayscale (see below), this picture is a 256 color grayscale.
To use this map, it depends entirely on the luminance information in this chart because DISPLACEMENT displacement map, the darker the picture in place of a deeper relief effects (depression), the more light in place of the relief effect of the higher ( protruding). Image adjustment can be dealt with well in advance in PHOTOSHOP.
6) assigned to PATCH objects to this material. Found that there is no miracle, never stop using NURBS replace this PATCH, should not unravel the. Back to the main interface MAPS shutter. To change the default value of about 10 displacements. Shown in Figure 2.
Figure 2
7) what next? Add a lack of detail DISPLACE (displacement) modification devices? It entered a misunderstanding of the. Switch to modify the panel, in the modifier list to find * DISPLACE MESH space distortions class modifier, shown in Figure 3. This modifier will allow us to map the window to see the effect of displacement. This time window can be noted that the PATCH on with a small change is the lack of details of the relief effect.
Figure 3
8) The rendering window PATCH, results can be found not satisfactory. This is not adjusted * DISPLACE MESH modify parameters, since it is not enough surface area, surface, embossed effect the lack of details. Check the CUSTOM SETTINGS (user-defined settings) check box, after waiting more than ten seconds after the window PATCH relief effect out! Operation See Figure 4.
Figure 4
9) In the window, select the PATCH objects, right click and choose right menu PROPERTIES (property), you can see at this time there are more than 80,000 surface PATCH. The breakdown of the system default level is MEDIUM (middle). LOW (low) or HIGH (high) results from the decision of individual machines.
10) If the need is not a square column, start can PATCH into a cylinder, and add a UVW map (to use the cylindrical mapping method). But with the BEND modifier also allows a side piece into a cylinder. Add to PATCH a BEND (bending) modifier, the bending angle (ANGLE) is set to 360 degrees, and bending the shaft to select the X axis. This will be a "Panlong column" shape. Figure 5.

11) But this is not a model of the results obtained. Since * DISPLACE MESH is a space distortion modifier, using conventional methods of collapse, no matter how MESH collapse can not get a grid object. In 3DS MAX, the use of snapshot is a faster and better way. Select column, select the menu TOOLS / SNAPSHOT, in the pop-up a "snapshot" dialog box, confirm CLONE METHOD (copy option) for the MESH (grid object), press the OK button. Shown in Figure 6. This will be a real EDITABLE MESH objects. Remember to delete the original post.

12) The remaining work is to hit lights, to the "Panlong column" Fu and select the appropriate background material. As Panlong column is a symbol of luxury, I use the brass material. As the material issue is not the focus of this tutorial, so I would not go into details. The effect of the final rendering as shown in Figure 7. How, Heart of it!

Notice:
1) for the displacement of the gray-scale map is very important! If you take a plane that live and work has in general, the best expert to deal with you, please print the displacement map. The displacement map tutorial handled and not good enough, if handled better, so that the brightness over a smoother, bump requirements fully into account, the effect would be even better! 2) If the model found that there are many sharp points, increase the displacement map of the BLUR OFFSET (fuzzy offset) on it.
