Bottle on table

This tutorial will show how to create the simple scene of the following picture:

Creating the table

To create the table, use the right button of the mouse and select the new/primitive/box command from the pop-up menu.
A box will appear in the windows. Now, you have to resize the box in order to have a table. Select the object (when selected, an object has green shape) and click on the control points on the vertices to scale it, as described in the following image.

In order to see the object in the camera view, you have to set up the camera. You can do this simply by selecting the camera and moving it: in this way you will able to see the box. Assuming that you have scaled the box in order to obtain a table shape you can see now the results in the following image.


 

Creating the legs of the table

Now, you can create the legs for the table. To do these, you have to use cylinders, if you want rounded legs. The cylinders can be created using the usual command clicking on the right button of the mouse (New/primitive/cylinder). Now, select the cylinder and scale it. In order to have four cilinders you have to duplicate the first with the command Edit/Duplicate. Move the four cylibders and position them at the angles of the table.
 

Assigning a material

The table you have obtained now needs a material. Behemot Editor allows you to create, modify and delete materials. Behemot provides a material library also, in which you can save the materials you have created. In order to work with materials see Objects, materials and textures.
To assign a material that you have already created follow these steps:

Now your object has been assigned.
 

Assigning a texture

You can now apply to the table a texture, for example the image wood.jpg. This texture has already been created and is stored in the same directory of the scene. To apply the texture to the object you have to map the object before. The command Edit/Mapping/Create allows you to create a mapping for this object, which is planar and so also the mapping will be planar. It will appear two axis, X and Y, and you have to position them in order to cover the object surface.
At last, you have to hide the mapping coordinates (Edit/Mapping/Hide).
Now, you can apply the texture wood.jpg to the table. Follow these steps:

Now the table has the texture "wood".
 

Adding a lamp

In order to correctly render the scene you have to add a lamp (and this is true for all scenes!!).
You can add lamps from the right-clicking menu New/lamp, and you can choose between three types of lamps.
Now you can start with a first test rendering.
 

Creating the bottle

To create the bottle it may be suitable to work in a layer different from the default one. So, you can create a new layer using the command Layer/create. Assign a name to it, say "bottle", then use command Layer/select and select the layer "bottle". Now you are ready to work clearly to draw thw bottle. To help you in doing this, you can press the button F12 and the axis will appear.
Now, you are ready to draw the shape of the bottle. Click with the right button of the mouse and choose New/curve/polyline.New control point must be added selecting a control point and pressing the 'a' button; the selected control point may be deleted using the 'd' key (more information on curve page). Then move the control points of the curve in order to trace the bottle profile, as you can see in the following image.

Now that you have created the profile, you can create the brep, as shown in the following image.

The bottle so obtained will appear, in the front and the top view, as shown here:

To come back to the default layer use command Layer/select and choose "default".
You have now to move and scale the bottle in order to put it onto the table. You need only to assign a material to the bottle to complete the scene. You can do this using command Edit/material/modify and changing the parameters in the box shown below.
