AutoCAD 2006 and earlier versions

Hello everyone,

First of all, let’s learn about the landscapes first. Landscape is used to model an entity in 3 dimensions where we have only a 2 dimensional picture of that object. For example, flower, battery and stewpot that are shown in the render below are landscapes. Even though landscapes are composed of only a photo; they can create shadows over their own shapes.

Fig. 1

Now, together let’s take a close look at how landscapes are defined.

 

When you run the LANDSCAPE command, you can create a new landscape library by using landscape library window; you can edit landscapes in the library and add new ones.

Fig. 2

In order to create a new library, it is enough to save the existing one with a new name. By this way, we will have a new library with a different name and it will include all of the landscapes. By deleting the ones that we don’t want we can create a library that is suitable for us.

As we have created a new library, now let’s define a new landscape. In order to define a new landscape, we press “New” button and open Landscape Library New window. In order to define a landscape, first we need a photo of the object that we would like to define. Then, we have to make some adjustments on this photo. Let me give an example immediately, and show you what to do.

Let’s say that we need a cup. To do this, first we need to find a photo of a cup. In order to find photos I generally use Google Images website. Picture that you will find is generally a photo that has a mixed background, as shown in Fig. 3, so it cannot be used directly. First of all, we have to select the area in the background of our image and make it black. Then, we have to copy this photo and we have to select the area where our object is and make it white as shown in Fig. 5.

Now, let’s copy these photos to texture folder which is either the folder that we defined as Texture Maps Search Path or texture folder under AutoCAD directory. As the required picture files are ready, now we can define our landscape.

Fig. 6

We will write the name that we want to assign to the new landscape into the name part in Landscape Library New window. Then, we write the name of the file in Fig. 4 with its extension (name.jpg) as image file. And we write the full name of the picture in Fig. 5 as “Opacity Map File“. Due to the fact that we have put all of these files into a predefined directory, what we need to enter is only the filenames. However, if you put the files into any arbitrary directory but not the folder as I describes previously, then you have to write full names of the files including the directories into these fields.

In the upper left corner, in “Default Geometry” field, we are determining how the landscape looks like. If single face is selected, then our photo will be shown on one single face only. If “Crossing Face” option is selected, then the photo will be assigned to two different surfaces that are perpendicular to each other. This method can give better results for symmetrical objects. In this part, by using “View Aligned” option at the bottom part, we can make the landscape be perpendicular to our look. All of these entries are to construct a suitable set of settings. Thus, you can change all of these settings during or while you are inserting landscapes. From the following examples, you can see it more clearly. In Fig. 7, from left to right, “Single Face-View Aligned“, “Crossing Face-View Aligned“, “Single Face“.

Fig. 7

As you may have noticed, in Fig. 7, cups are sitting a little bit higher on the shelf. The reason for this is that there is a space under the picture that we use as resource. If you want the object to sit exactly on the surface, than there should be no space under the object. As we have created our own landscape, now we can insert it into our drawing.
Insertion work is quite simple. After you run the command, you adjust the required settings and select the point that you want as insertion point. Then you complete the command by OK button. Here, Height determines the height of the object in z direction in terms of dimension unit that is used in the drawing. As the height increases, width changes by the same proportion.

Landscapes were removed with AutoCAD 2007. It only works in version before AutoCAD 2007.
