GuIrit is an ever-evolving GUI (Graphical User Interface) to IRIT. It is
under ever-going development but is certainly in a usable form. It
includes:
A graphically based user interface to create, display, manipulate and
process geometry.
Access to most of the functions in the IRIT interpreter (Irit.exe)
and build above the IRIT package. Any other IRIT (or arbitrary)
function could be easily exposed as well using DLL extensions (See below).
Programmable extension interface. Many of the existing functions in
GuIrit are built using this extension interfaces that allows one to create
external extension as DLLs (or shared libraries on non windows platforms)
without resorting to rebuilding guirit.exe.
Using wxWidgets, and hence it is
suppose to be relatively simple to port to other environments.
So far, GuIrit was tested on Windows XP/Vista/7 and Linux Fedora, and
to a lesser extent on MAC OSX. Herein, we provide executables for
Windows XP/Vista/7 as well as the C/C++ sources.
Some examples
Here are some short movie examples of the capabililies of GuIrit (You
will need the DivX, http://www.divx.com,
codec to see these movies):
Display 1:
A first example of display control over the geometry. Show how to
change different display modes, like wireframe/shaded display and
shadows and refelctions.
In all examples you can watch the Ctrl/Atl/Shift modifiers
state at the bottom right corner. For example "C LM" denotes
Control-Left-Mouse button.
Display 2:
A second example of more display control over the geometry. Show the
use of three shadows on the three pricipal planes.
Primitives and Booleans:
A simple example of primitive object creation using the
interactive update option of (numeric) parameters, using right-mouse
click-and-drag over numeric widgets. This example also shows a
simple Boolean operation - with its geometric parameter selection
performed via the GUI combo or by object-select-and-drag.
This demo uses GuIrit DLL extensions GuIritDllPrims.dll and
GuIritDllBoolOp.dll
Curve drawing and editing:
Ability to sketch a curve and then multiresolution editing of curves.
This demo uses GuIrit DLL extensions GuIritDllCrvSketch.dll and
GuIritDllMRCrv.dll
Construction an extruded surface:
Show one surface constructor (extrusion) by selecting a circle costructor
as its curve parameter which allows interactive update of all parameters
of both the circle and the extrusion constructors.
This demo uses GuIrit DLL extensions GuIritDllSurfaces.dll (for the
extrusion) and GuIritDllCurves.dll (for the circle). Again, right-mouse
click-and-drag is used to modify numeric widgets.
Dependencies:
Building a circular plate with two conical holes, that are computed
as Boolean subtraction.
Using (active) dependencies, any change in the parameters
of the circular plate (a cylinder) or the two (truncated) cones is
immediately reflected in the final result.
Malfatti: An example of using
the multivariate solver of Irit to solve the Malfatti problem in real
time - find the three largest (actually not the largest) circles
tangent to each other within a triangle (solution of 9 quadratic
equations in 9 variables).
Surface From Curves:
Fit a surface through curves while editing the curves
(and surface). Operation also known as skinning.
Simple Animation Creation:
Transform a truncated cone (including non-uniform scale) and then apply
the transformatio nto the cone, only to animate it in both motion and
color.
Manual Installation of the Windows version
If you use Windows XP and unless you have MS Visual Studio 2008
(9.0 .net) SP1 installed on your
system you will also be required to install (once only) the run time env. of this compiler from
Microsoft.
Go into the directory in 2, and run GuIritInstallGuiCfg.cmd (once only).
This creates a directory "%USERPROFILE%\Application Data\GuIrit" and
place there a default GUI configuration file.
Run GuIrit.exe. If everything worked out fine, you should see something
like in the "1st Run" section below.
The installation also includes some minimal documentation and a few
models as an example, in the Docs and Models sub directories.
Automatic Installation of the Windows version
If you use Windows XP, you can also download GuIritInstall.exe and execute it for
an automated installation
Run GuIrit.exe. If everything worked out fine, you should see something
like in the "1st Run" section below.
The installation also includes some minimal documentation and a few
models as an example, in the Docs and Models sub directories.
A comment in Windows 7. In Windows 7 the %USERPROFILE% expansion is
different and hence you will have to text-edit the cfg files and
GuIritInstallGuiCfg.cmd to the proper directory.
1st Run
Click on the image for an enlarged view.
Make sure, when you run GuIrit, that the messages that appear in the
bottom left window are not in the red color, meaning everything
loaded/initialized fine.
The sources
GuIrit is a graphical user interface for the IRIT modeling package and
is built using wxWidgets. This
means you will have to download these two packages and build them
before you can built GuIrit. These tasks are NOT trivial and unless
you consider yourself knowledgeable, please do not attempt this. I
cannot provide support and/or answer compilation questions. Yet, some
'readme' information could be found in the Docs subdirectory of the
Guirit Distribution. For latest (alpha version) GuIrit sources, see
here.
