Preface:

The author has issued six "Render Tutorial" 8 "play up the experience," and "Modeling of the 22 examples of exaggeration", but still require some beginner steps in detail. Recently, members of a CAD 2008 【】 rendering problems with the title, for help in mapping CAD2008 in the specific methods, this response to the article for the novice CAD users a high version of the reference rendering.

First, set the "global" parameter, so that block with the color rendering

Generally speaking, those who are not specifically designated material attached to a block (or pixels), and three-dimensional body of the pixels are subject to material panel's "overall" control of the ball material, that is, the "overall situation" of set parameters to control its rendering block. For example as follows:

There is a plate of three-dimensional map, to be turned into a white porcelain plates, how do set up?

In my opinion: To play up the ceramic materials, they are advised in the use of materials: Type: true; model: tiles, glazed can. Accordingly, in the material panel, "Global" ball material, the selection of type: real; model: tiles, glazed; color: white; reflective about 90 degrees; refraction: around 1.4. 1 left as illustrated below:

This setting, no longer attached to the three-dimensional entities of any material, the implementation of "playing up" command, you can play up the white porcelain of the right as shown in the above chart.

If you want to play up the color of porcelain for the other, the color can be changed. Of course, if a face plate attached to the other material, then attached to the surface will be a different color.

Second, how to assign raster image as a material entity

For example, to play up the blue and white porcelain plate for how to do?

First of all, the panel material to hit the "Create a New Material" button, can be named as the "blue", and then, in the "diffuse map" in your browser and select blue-and-white image files.

Secondly, in the "Material Editor" select the type: real; model: tiles, glazed. Other parameters can be set up like the first.

Once again, assigned to the material (pictures) also need to adjust the plan, and above in 2007, the hit "material" board "texture mapping" button can be set up right: in the "zoom and balance" cards, the general the proportion of units used is "for object", U, V flat from 1.0, if unhappy on the adjustment of the ratio of the following value or offset value, the debugger must do repeatedly, there is no fixed parameters or patterns. Set up after the panel material 2 such as illustrated below:

After this set, you can assign materials to the plate (picture), but assigned to the entire three-dimensional body of material, sometimes unhappy, there has been assigned to the plate image, the graphics are messy (as shown in illustration 3 left) This plan needs to be adjusted a bit.

How do? By "mapping" feature to adjust. In the "map" functions are: planar map, rectangular mapping, cylindrical mapping, spherical mapping of four, according to the appropriate object of "mapping" method to adjust the material has been affixed with a picture, especially for surface and round three-dimensional pieces, it is difficult to picture affixed in place it is sometimes necessary to use "cuboid map" or "spherical mapping" function repeatedly adjusted, and the "mapping" function and it is very difficult to master, one must move the computer mouse run very far, it has to be very difficult to adjust the patient in place.

On the plate, if the pattern at the end of the disk in place to adjust, then hit "map / print map" feature, hold down the Ctrl key and set the bottom line activation loop, you can see the corners with "▲"-shaped zoom box, the box will live set at the end of the pattern on the Reformed (see illustration 3 below right). Then, re-adjustment of the disk images are in place, the same as, the Reformed left icons such as shown in illustration 4. Finally, the top plate of the ring also adjust the pattern in place (for example, as shown in Illustration 4).

As sub-plate and the edge of the back plate, such as the laws do not need and then design, make it a color, then hold down the Ctrl key and activate the associated coil, and then hit the panel material "from the selected object deleted material "button. (See Illustration 5 arrows indicate Department)

This setting, the surface is no longer attached to any other material, and then the implementation of "playing up" command, you can play up the effect of a blue and white porcelain plate is as follows Fig.

Third, how different the picture would be, respectively, by surface mapping

If the paste after "Mission to spend Lunar New Year", side plate affixed to blue, how do? The answer: This is the need to re-panel materials "to create a new material" can be named as material 1, and then, in the "diffuse map", the browser and select the "Lunar New Year Flower Mission," the image file. In this way, the ball three materials, and its parameters such as the illustration shown in Figure 6.

How to assign disk, respectively, at the end of the ring and set it above? The second paragraph above has been described here is not re-Syria, followed by adjustment of only Reformed pattern out of the screenshot.

1, with "flat map" feature to adjust, "Lunar New Year flowers" Reformed after pictures to the screenshot (Illustration 7):

2, with "flat map" feature to adjust, "blue" ring pattern to the disk Reformed screenshot (Illustration 8):

3, with "flat map" feature to adjust, "blue" ring pattern to the disk are similar to the screenshot method Reformed omitted.

This set-up and adjustment operations, the implementation of "playing up" command, the map rendering results obtained are as follows:

Fourth, the four sub-surface texture mapping

If you would like the effect of Figure 2 for the disc are eight missions for the flowers, and the side plate sub-rendering for the gold color, this is the four sub-surface of the material. Here, we would also like to create a yellow material, type: High metal; Color: golden yellow, reflecting the value should be around 60, high color white metal, low metal, if necessary, reflection mapping needs to be set up, otherwise, metal color will dim. Rendering the effect of this plan are as follows:

Fifth, both texture mapping and bump mapping of the background graphics

Bump mapping is generally light gray display, but in the "diffusion" can change its color. However, it is necessary to reflect the change in color, but also take into account the color texture mapping, it also would "diffuse map" to adjust the slider to the appropriate location, so that the existing pattern, color and more uniform, and See illustration 9 cursor arrow Department follows:

Other material parameters with the former, this set, then the implementation of "playing up" command, it turned into a porcelain embossed ocher, as follows:
