| 00:01 | Welcome to the Spoken Tutorial on 3D Objects in LibreOffice Draw. |
| 00:05 | In this tutorial, you will learn how to create 3D objects using the following options:
Extrusion 3D Toolbar 3D Rotation Object. |
| 00:16 | You will learn to edit and apply 3D effects to objects and create special effects using Duplication. |
| 00:24 | To use this tutorial, you must be familiar with Basic and Intermediate level tutorials in Draw. |
| 00:30 | Here, we are using: Ubuntu Linux version 10.04 as our operating system and LibreOffice Suite version 3.3.4. |
| 00:40 | Let’s create a geometry chart which shows a 2D shape and equivalent 3D form. For example, a square is a 2D object, a cube is its 3D form. |
| 00:53 | We have a new Draw file here, named as "3DObjectsChart". |
| 00:59 | Before we begin the drawing, let’s enable the grids and the guide lines. We have learnt about this in previous tutorials. |
| 01:08 | From the Main menu, click on View, select Grid and Display Grid. |
| 01:17 | Then again click on View, select Guides and Display Guides. |
| 01:23 | I want to set both the rulers to centimeters. |
| 01:29 | Place the mouse pointer on the horizontal ruler. Now, right-click and select Centimeter. |
| 01:38 | Place the mouse pointer on the vertical ruler. Again, right-click and select Centimeter. |
| 01:45 | Let us now draw a text-box on the top of the page. |
| 01:49 | Let’s insert the text: "Geometric shapes in 2D and 3D", inside it. |
| 01:55 | Let us now divide the page into two vertical halves using a snap line. |
| 02:01 | Click on the vertical ruler and drag it to the Draw page. |
| 02:05 | A vertical dotted line appears. |
| 02:08 | Place the dotted line on the page such that the page is divided into two halves. |
| 02:14 | Let’s insert a text-box on the left side and type "2D Shapes" inside it. |
| 02:23 | Let’s draw another text-box on the right side and type "3D Shapes" inside it. |
| 02:30 | Let us enable the 3D toolbars. |
| 02:33 | From the Main menu, click on View, select Toolbars and 3D-Objects. |
| 02:43 | Again, click on View, select Toolbars and 3D-settings. |
| 02:53 | The 3D-Objects and 3D-Settings tool-boxes are displayed. |
| 03:02 | We will first draw the 2D shapes. |
| 03:05 | We will draw a rectangle, a square, a circle and a triangle and place them one below the other. |
| 03:14 | The method of obtaining a 3D object, using a 2D object is called Extrusion. |
| 03:19 | Basically, the surface is moved outward to create the 3D object. |
| 03:25 | First, let us change the colour of the rectangle to "Turquoise 1". |
| 03:31 | Let’s make a copy of the rectangle. |
| 03:35 | Let’s drag the copied rectangle and place it on right half of the page. |
| 03:40 | Now, while it is still selected, right-click to view the context menu. |
| 03:45 | Now, click on Convert and select To 3D. |
| 03:48 | The 2D rectangle is converted to a cuboid. |
| 03:52 | Let’s type "Rectangle" inside the rectangle shape. |
| 03:55 | However, we cannot type text inside 3D objects. |
| 04:00 | To type text, we need to use the Text tool. |
| 04:04 | Click on the Text tool and draw a text-box inside the cuboid. |
| 04:10 | Type the text "Cuboid"' inside it. |
| 04:14 | The text-box and the cuboid are treated as two separate objects. Therefore, let’s group them. |
| 04:21 | Similarly, we can colour and convert the square, circle and triangle into 3D objects. |
| 04:30 | We have used extrusion to create a chart of 2D and 3D figures. |
| 04:36 | Pause this tutorial and do this assignment. |
| 04:40 | Add a new page to your Draw file. |
| 04:42 | Draw a square and type the text "Square". |
| 04:46 | Convert the square with text to 3D. |
| 04:49 | Compare with the text from the 2D square text. |
| 04:53 | Hint: Use the 3D Settings toolbar to create 3D objects. |
| 04:58 | Draw also provides ready-made 3D shapes. |
| 05:01 | You can insert these shapes using the 3D Objects toolbar. |
| 05:09 | Let’s insert a new page in our Draw file. |
| 05:13 | Let’s select a shape from the 3D-Objects toolbar, say Shell. |
| 05:18 | Then draw it on the page. |
| 05:24 | Draw also allows you to create 3D objects using body rotation on 2D objects. |
| 05:33 | Let’s draw a 2D shape, say a circle, on our Draw page. |
| 05:39 | Right-click for the context menu and select Convert. Then choose To 3D Rotation Object. |
| 05:47 | Observe what happens to the circle. It is now a 3D object. |
| 05:54 | Click on the Fontwork Gallery icon on the Drawing toolbar at the bottom. |
| 05:59 | Let us select Favorite 16 and click on the OK button. |
| 06:04 | The text Fontwork is displayed on our Draw page. |
| 06:09 | We can re-size this text as required. |
| 06:12 | Now, we may want some other text in its place. How do we do that? |
| 06:17 | Simply double-click inside the text "Fontwork". |
| 06:21 | Now, you will be able to see the word Fontwork in black colour within the larger text. |
| 06:26 | Select this text and type "Spoken Tutorials". |
| 06:30 | Now, click anywhere on the Draw page. |
| 06:33 | The words "Spoken Tutorials" will now be displayed on the page. |
| 06:36 | Next, let us learn how to apply effects on 3D objects. |
| 06:41 | Let us apply effects to a spherical shape. |
| 06:44 | So, let us select it and right-click for the context menu. Now select 3D Effects. |
| 06:51 | You can see various options here. |
| 06:57 | For demo purpose, let us change Depth parameter to 3cm. |
| 07:05 | Under Segments, let us change Horizontal to 12. |
| 07:10 | Under Normal, let us select Flat option. |
| 07:14 | Observe the appearance of the object in its preview window. |
| 07:19 | Now, click on the Assign icon at the top right-hand corner of the dialog-box. |
| 07:26 | Next, click on the X mark at the top left-hand corner to exit the dialog-box. |
| 07:32 | Observe our shape now. The effects we selected have been applied to it. |
| 07:38 | Here is an assignment for you. Create a similar picture like the one shown on the slide. |
| 07:45 | Use the 3D Effects dialog-box to achieve this. |
| 07:49 | You can also create special effects using Duplication with 2D and 3D objects. |
| 07:55 | Let’s create a new page and draw a rectangle in it. |
| 08:00 | Let us create an effect using Duplication on the 2D rectangle. |
| 08:04 | From the Main menu, select Edit and click Duplicate. |
| 08:09 | The Duplicate dialog-box appears. |
| 08:12 | Let us enter the following values - Number of copies = 10 |
| 08:18 | Under Placement, X Axis = 10 |
| 08:26 | Y Axis = 20 |
| 08:30 | Angle = 0 degrees. |
| 08:34 | We will keep the Enlargement Width and Height as default. |
| 08:44 | We will change the Start color to Yellow, End color to Red. |
| 08:57 | Click OK. |
| 08:58 | Look at the great special effects that we have got! |
| 09:04 | You can get many more effects by changing the angles and the other values. |
| 09:09 | This brings us to the end of this tutorial. |
| 09:12 | In this tutorial, we have learnt how to create 3D objects using the following options:
Extrusion 3D toolbar 3D Rotation Object. |
| 09:23 | We have learnt to edit 3D objects and apply 3D effects to objects. |
| 09:27 | We also learnt to create special effects using Duplication'. |
