Step 1: Create a new file

This is simply to have a clean area to work in. 'Nuff said.

Step 2: Create two spheres.

These will form the basic shape of our vase. Set their attributes by clicking on the [A]. Set the attributes for both according to these pictures.

Step 3: Create a torus.

This will eventually produce the flared neck of the vase. Click on the [E] to edit the radius (highlighted in red). Set it to 422 as shown.

Next, edit the attributes (highlighted in blue). Set it according to the picture.

Step 4: Create a cube.

This will create a flat portion as a base for our vase. Set its attributes to the ones shown.

Step 5: Create a cone.

This will indent the neck of the vase, giving it the illusion of being hollow. Set the attributes as follows.

Step 6: Create the vase!

At this stage your vase will look like a jumble collection of shapes. Which in fact it is. The final step in creating the vase is to select all of the above shapes, and group them together by clicking on the [G]. The shapes with negative attributes will remove pieces of the ones with positive attributes, thereby creating an elegant vase shape. Render you image and see how the negative shapes function

Step 7: Finishing touches: Texturing

This stage is entirely optional. You are free to apply your own textures, or materials from the standard library. Some examples are shown here. Also, I would recommend you go back and play around with the shapes, scale and position, and see how versatile this basic shape can be.

Here, we are going to apply a blue china texture, which is available in the support file at the start of the tutorial. Unzip the texture to somewhere you will able to find it easily.

Step 8: Applying the texture.

With your entire vase selected, click on the [M] to enter the materials lab.

On the texture palette to the right, click on the image texture button [P] (shown here in yellow). Then click on the image source editor button (shown in green). This will take you to another window, where you want to click on the first empty tile down the bottom (highlighted in red), and browse to where you unzipped the image. Then, make the second picture pure white by clicking the white circle above it (highlighted in yellow). Click the okay tick, and we have returned to the materials lab.

Click on the transformation tools button (shown as no. 3 in red) and adjust the scale by clicking on the centre of the scale control and dragging to the right. If you have altered the proportions or scale of the vase itself, you'll need to play around with this setting until it looks right. 10% should do if you have stuck to the tutorial.

Ensure that the settings in the centre are the same as in the diagram, and click the OK tick on the mat lab.

Step 9: You Render

Frame the vase in the window, and render. Voila! You have created a fully-textured vase. Congratulations. You now have a very classy vase to place in your renders.

Remember to save your file!

Hopefully this has given you an insight into negative shapes, and applying your own textures.
