OpenShapeFactory: open-source geometry kernel

May 17, 2012

Abstract

This is the official documention of OpenShapeFactory, in the followingsections we will introduce the reader to OpenShapeFactory, and documentin detail every command available to the system. OpenShapeFactory is anopen-source BREP programming language, it enables to automate BREPsusing an economical codex of functions and routines, OpenShapeFactorymakes extensive use of the open-source BREP geometry kernel Open-Cascade, and the Qt Library for Graphical User Interface and scriptingfacilities.

1 Introduction

Figure 1: Diagram of OpenShapeFactory internal structure

OpenShapefactory is a MiddleMan between you, OpenCascade and QT, itserves as a Geometry Factory wrapping OpenCascade, and providing a single-point of entry to the creation of most geometrical operations.In a Gecko - Open-ShapeFactory allows you to:

1. create Brep-Geometry: i.e ( sweeps, loft surface, revolvesurface, face,edge,etc);

2. visualize the geometry into a 3d viewport.

3. link QtWidget’s created manually in the Qt-Designer to Update Functionsthat Create Geometry.

4. Get direct access to the HSF library using QtScript( ECMA/Javascript)using the ScriptWidget.

5

2 Boundary Representation

The Geometry in OpenShapeFactory is represented using Boundary Represen-tation, Boundary representation models are composed of two parts: topologyand geometry (surfaces, curves and points). The main topological items are:faces, edges and vertices. A face is a bounded portion of a surface; an edge is abounded piece of a curve and a vertex lies at a point. Other elements are theshell (a set of connected faces), the loop (a circuit of edges bounding a face) andloop-edge links (also known as winged edge links or half-edges) which are usedto create the edge circuits. The edges are like the edges of a table, bounding asurface portion.[from Wikipedia]

Part I

Interface

3 The Application

Figure 2: Main Interface of OpenShapeFactory

The openshapefactory is divided literally between a 2d surface left and a3d surface right as shown on figure 2. the 2d surface is a diagrammatic panelwhere widgets are loaded, in the case of the precompiled download, a QScintillatext-editor widget with programmatic access to the openshapefactory is auto-matically added as the only widget. To the right of the 2d panel you have the

6

3d view port, any change to the code that results from a visible shape will beimmediately visible in the 3d view port.

3.1 Code Editor

Figure 3: The Code Editor

3.2 Menus and Toolbars

Figure 4 indicates the available menus and toolbars:

3.3 ViewPort Manipulations

basic 2d manipulations:

1. panning : right-click and drag on 2d panel background

2. zoomming : use the scroll-wheel on your mouse, or the right side of yourtouch pad on a laptop

3. moving widgets : left-click and drag on the gray area around any widget

7

Figure 4: Menus and Toolbars

basic 3d viewport manipulation:

1. panning : press control + holding down the middle mouse button(scrollwheel)

2. zoom : press control + holding down the left mouse button

3. orbit : press control + holding right mouse button

OpenShape Factory Commands

4 Sliders

4.1 getval(position,minval,maxval)

creates a slider in the front end of the scriptwidget, position is the order inwhich you would like to display the slider in the front end, if you specify 0 asthe position it will be the first.

Minvalue is the left limit of the slider, Maxvalue is the right limit of theslider

5 File System and Misc

5.1 getfile

Displays a filesystem dialog to locate a file and returns the filepath of the fileselected.

5.2 getfileonce(filenamepath)

same as getfile except forces the system to load the file only once, notice howcheck shows on the interface allowing the user to select whether they want torespect the single execution of the operation.

5.3 getdir

opens a filesystem dialog for locating a directory or folder

5.4 getdironce(dirpath)

same as getdir except forces the system to load the directory only once, noticehow check shows on the interface allowing the user to select whether they wantto respect the single execution of the operation.

5.5 readcsv(filename);

9

5.6 watchfile(filepath)

link the evaluation of the script to execute, for every change in the file speci-fied by filepath. if for instance you watch an igs file and that file is afterwardsmodified by Rhino or Catia, simply by overriding the file, the code in Open-Shapefactory will re-evaluate.

Part III

OpenShapeFactory ExamplesIn this section we will introduce, examples to illustrate the use of OpenShape-

Factory.

20 Make a single Point

Type the following code in the code editor and see the geometry update as youtype.

p1 = makepoint(0,0,0) // create a point

vis(p1) // showpoint on viewport

21 Make a Point Loop


for(i = 1 ; i < 100 ; i++)

{

p1 = makepoint(i*i,i*10,0) // create a point


}

22 Make a Line Between 2 points






l1 = makelineptpt(p1,p2) // make a line between 2 points

vis(l1) //show the line in the viewport

23 Kilian Roof

In this example we demonstrate how to create a loft surface by developing acustom crossection using user defined functions, also populating panels on thesurface using a user defined panel delegate function as shown in figure ??.

17

Figure 8: Kilian roof Example

I have provided an utility function called panelize, this function subdivides asurface into rectangular regions, as many regions you want on the u direction ofthe surface, and as many regions you want on the v direction. on each region youwill always get 4 points, this is the signature required by your custom function,in this case called mypanel, this function accepts 4 points, inside the functionyou can do anything you want with those 4 points, the 4 points represent the 4corners of each panel, in this case we draw 2 diagonals across p1-p3 and p2-4,since this executed over all panels, we get the effect of diagonals running acrossthe overall surface, when in fact the effect is only being executed on a per panelbasis, have fun!.

when running this example make sure the x1 x2 x3 and x4 sliders are dis-tributed in an incrementing order at first, for example set x1 at 0 , x2 at 25 ,x3 at 50 and x4 at 100

the sliders represent the 3 points of the spine controlling the surface, if theyare twisting in space the surface might not generate as nicely, the z value ofeach point controls the width of the crossection at each interval.

minval = -300

maxval = 300

x1 = getval(0,minval,maxval)

y1 = getval(1,minval,maxval)

z1 = getval(2,0,maxval)
