AV Bros. Page Curl Pro 2.x Tutorial

Introduction and Specific Terms Explanation

We will explain the techniques that we have used while preparing the samples for our gallery. Here we must say that we assume that you are familiar with the basic techniques described in the User Guide of AV Bros. Page Curl Pro, such as "How to orient the page in 3D space?", "How to texturize the page?", etc. If you are not, then please take a look at the "How TOs" in the User Guide (pp.48-53), because we will refer to them when necessary.

Note! When creating the design of the samples in the Gallery we used AV Bros. Page Curl Pro 2.2 (the 2.0 or 2.1 versions of the plug-in are suitable as well) installed under Adobe® Photoshop®. Any version of Photoshop started from version 7.0 is suitable without any special "corrections" for the host. You may also use any supported host, (Please check the appropriate list at http://www.avbros.com/english/pagecurlpro/index.html) just be aware that some of the features of the plug-in (E.g. the ability to use the content from any layer of the current document as the content of either side of the page.) are available only for Adobe Photoshop 7.0 and higher.

To make things easier, we will re-publish here the explanations of the specific terms that were described in the User Guide (p.3):

The Host: this is your image editing application. AV Bros. Page Curl Pro is the plug-in for your host.

The Page is the object that you are about to bend (to curl or fold). The Page has two sides: the Front side and the Back side.

An Active Layer of the current document is the layer with which you are working in your host. When you start the plug-in, you begin operate with the content of the Active Layer.

The Bend is the result of either the page curling or the page folding process.

The Multi-Bending: this is the term that we use to express the process of bending the page several times during one session of the plug-in.

The Conflict Area of the page is the part of the page where the conflict occurs between the active bend and other bends and where the page cannot be bent. This conflict takes place when the current settings of the active bend cannot be applied without breaking the page's surface.

3D Space is a term of the 3D graphics that is used to describe the virtual area that emulates the real space around us. Unlike 2D graphics, where all objects have only width and height, in 3D space the objects also have depth. Using mathematical terms: if in 2D graphics you use the X and Y-coordinates, then in 3D graphics you use the X, Y and Z-coordinates. The 3D space is represented by the sphere, which we divided in two (2) hemispheres (the Front and the Back hemispheres) for the most convenient orienting the page in 3D space.

The Central Point is the geometrical center of the page and is used as the center of the rotation of the page while orienting it in the 3D space.

The Bump Map is a grayscale image that you can use for producing the 3D-like effect of a texturized page.

The Backdrop is an image that is placed beneath the Page in the Main Preview area and is solely used for indicating the transparency under the curled, folded or transparent parts of the Page.
