Tutorials

The CEETRON Envision documentation provides a large collection of examples, tutorials and code samples. These pages cover a range of topics, from basic viewers to step-by-step tutorials for specific features.

The examples and tutorials are provided with full source code and can be compiled and run on several platforms and UI toolkits.

Tutorials

The tutorials focuses on how to use the different visualization features provided in CEETRON Envision. Select one of the tutorials in the list below to go directly to the documentation and the step-by-step instructions.

img_tt

UnstructGrid: Simple Model with Two Triangles
Shows how to create your own part and to use it in a model.
The geometry is a very simple structure containing two triangles only.

img_twr

UnstructGrid: A Simple Model with Results
Shows how to build an UnstructGridModel geometry, part and results.
The geometry is a very simple structure containing a single triangle and
a scalar result mapped as fringes, a vector result and a displacement result.

img_lf

UnstructGrid: Load Model from File and Set Up Model Specification
Shows how to create a data source by loading a VTFx file and how to setup a
model specification

img_cp

UnstructGrid: Create a Cutting Plane with a Scalar Result as Fringes
Shows how to create a cutting plane and show a scalar result mapped as
fringes to the surface.

img_is

UnstructGrid: Create an Isosurface
Shows how to create an isosurface based on a scalar result id and a scalar
value.

img_iv

UnstructGrid: Create an Isovolume
Shows how to create an isovolume based on a scalar result id and a maximum
and minimum scalar value. In addition, the scalar result will be shown as
fringes on the isosurface.

img_ps

UnstructGrid: Apply Part Settings to a Model
Shows how to apply some part settings to parts in the model.
(Part 1: Set invisible, Part 2: Set color to blue, Part 3: Set draw style
surface mesh, Part 4: Set opacity)

img_ss

UnstructGrid: Set Scalar Settings on a Loaded Model
Shows how to change scalar settings for visualized result.

img_vs

UnstructGrid: Set Vector Settings on a Loaded Model
Shows how to change vector settings for visualized result.

img_des

UnstructGrid: Using DataElementSets to Filter the Model
Shows how to use DataElementSets to filter the model by specifying which
elements that are visible.

img_cdr

UnstructGrid: Create a Custom DataReader to Add Support for Your File Format
Shows how to get your own analysis results into the UnstructGridModel by
creating a DataReader. It is a very simple reader that returns one hexahedron
element with one scalar, one vector, one displacement and one transformation
result, but it will work as a starting point for building your own file reader.

img_m

Visualization: Draw Bounding Box Using Markup Model
Shows how to create a data source by loading a VTFx file and drawing the
models bounding box as a markup model.

img_cn

Visualization: Create a Custom Navigation Handler to Support a Custom Navigation Scheme
Shows how to create a custom navigation scheme by subclassing the
cee::vis::CameraInputHandler.

img_h

Geometry: Highlight Clicked Parts
Shows how highlight parts as a response to a mouse press event.

img_g

Geometry: Create a Geometry Model
Shows how to create a geometry model with different parts and effects.

img_gt

Geometry: Create a Geometry Model with Texture
Shows how to create a geometry model using the texture effect to show a
scalar result.

img_gp

Geometry: Create a Geometry Model with Geometric Primitives
Shows how to create a geometry with geometric primitives like spheres,
boxes and cylinders.

img_r

Report: Create a Simple Word Report with a 3D Model
Shows how to generate a Word report containg a 3D model.

img_p

Plot2d: Create a Simple Overlay Plot
Creates a basic 2D plot and shows it as an overlay item in the view.

The code of the tutorials is also available without the step-by-step instructions on the Code Examples page to make it easier to copy the code into your projects.

TutorialRunner

The tutorials can also be tested directly in one of the TutorialRunner applications. These are called QtTutorialRunner, MfcTutorialRunner, and WxTutorialRunner and can be found in their respective folders under Tutorials in your installation.

Please note that the TutorialRunner framework is not meant to represent best-practice code, and only serves as a convenient way to demonstrate the code in the tutorials. Please compile them in-source to find necessary test data.

Demo Applications

We have created two demo applications; One for Qt and one for Windows Forms. These can serve as a starting point for your own application, as inspiration and a best-practice-coding-guide. They also give a more in-depth demonstration of the Core, Visualization, and UnstructGrid components.
