Trucos de diseño para diseñar como locos
A couple of posts ago this blog talked about different ways to edit the vertices of an object in InDesign. The publication reached a commitment to further explain the shape functions and operations. Since it is also one of the most useful and common tools in design applications, I will dedicate a publication in detail.
There has always been considerable confusion with the name that this tool received in the Adobe suite, it is expected that the name of a function explain the purpose of it, which does not occur with the tool Pathfinder. This feature is intended to obtain aBoolean object resulting from the calculation of two given objects A and B.
Usually design’s applications called this function, more accurately, Boolean, Merger or Combination. It is possible that the ignorance many new designers have of this function is due precisely to the confusion generated by his name.
To apply this tool is essential that the surfaces of two objects overlap to a greater orlesser extent
Boolean fusion works as follows. Taking the role as operands two objects A and B, say that A is a rectangle at the bottom of the desk and B an ellipse that partially overlaps the rectangle A, the function will perform the following operations of Boolean algebra:
Applications such as QuarkXpress offer more interaction between the operands but most common is to find only the first four possibilities described.
The resulting object of this operation is a new surface assuming the properties of the two given operands, with control points themselves, as if it were drawn manually as shown in the image below. You can add new control points, edit existing ones, change the surface or combined with a new object.
Returning to the argument with which I began this publication, you can use Boolean combination’s functions in most of 2D and 3D applications with vector working surfaces. The Adobe suite have it under the name Pathfinder in most of its applications. Although Photoshop, for example, has this function built into the toolbar and allows use in selections and vector paths. In fact, the Adobe suite is so confused in this particular aspect of the tool Pathfinder than Illustrator has a completely different functionality, being called Boolean operations’ Shape Functions themselves. QuarkXpress referred to as Fusion and is available in the menu item.
