Development of an OpenVX* application can be done by creating a regular C project, adding the required include directories and manual writing the setup and teardown of OpenVX* boilerplate code, such as OpenVX* context and graph creation.
Another option is to create an OpenVX* project. Creating an OpenVX* project automatically generates the OpenVX* boilerplate host side code and provide convenient way to create and modify OpenVX* graphs.
An OpenVX* project is a regular C project that consists of several directories and files, as described in this chapter. Some of these files are automatically generated by the tool.
Opening the New OpenVX* Project Wizard
To create a new OpenVX* project, you can use the New OpenVX* Project wizard. Use one of the available options to launch this wizard:
- Click on the File menu and choose New -> Other… -> OpenVX -> OpenVX Project.
- Right click anywhere in the Project Explorer and choose New -> Other… -> OpenVX -> OpenVX Project.
- Click the New button () in the Tool bar and choose OpenVX -> OpenVX Project.
Using the New OpenVX* Project Wizard
In the New OpenVX* Project wizard window:
- Enter the Project Name
- Click on the Finish button to create the project
Viewing the Newly Created Project
The Project Explorer shows the newly created OpenVX* project.
The created project contains the following files:
main.c- Contains main function code including the setup and teardown of OpenVX* boilerplate host code such as OpenVX* context creation and graph verification.
common.c/h- Contains common functionality such as generic functions for keeping track of and releasing of OpenVX* primitives and other allocated objects.
Graphsfolder - Contains OpenVX* graphs of the application. Each graph is represented by two files (
.c). When creating a new application, this folder contains
hello_world.hfiles for the sample "hello_world" graph.
When creating an OpenVX* project, the following windows are displayed in the Eclipse main window:
- Kernels List Window – Contains a list of all available kernels. When new OpenVX* project is created, all the available kernels for the selected OpenVX* runtime are enumerated in the Kernels List Window. The available set of kernels are categorized into sub sections based on the kernel namespaces
- Graph Designer – Editor area for OpenVX* graph
- Property Window – Presents the properties of a selected node.
