This section includes description of samples provided together with the SDK. Samples included in the SDK developer pack are fully functional samples that you can build and run to see how the SDK works. You can reuse any of the code and techniques in the samples.

SDK QML GL Demo

Starting with the version 3.0, the NAVTOR SDK supports two rendering platforms: software rendering and GPU accelerated rendering with OpenGL.

SDK QML GL Demo Description

The SDK OpenGL QML sample demonstrates the GPU accelerated OpenGL chart rendering technics in the Qt Quick (c) application with the use of the shared texture.

The sample consists of the following folders:

• /pro - project files
  
• /res – resources
  
• /src – sources
  
• src/backend – classes that interact with the NAVTOR SDK
  
• src/gui - the user interface.
  

The application is based on QQuickView and uses QQuickFramebufferObject to integrate the NAVTOR SDK GPU accelerated OpenGL chart rendering.

The important detail in integration of the chart rendering is when and how to get the OpenGL context from the Qt Quick scene graph and how to synchronize the Qt Quick scene graph rendering with the NAVTOR SDK chart rendering.

It’s important because in this sample the NAVTOR SDK OpenGL renderer uses the shared texture, which allows to use the rendered texture by identifier without extracting the texture from one OpenGL context (NAVTOR SDK) to another (Qt Quick).

This method gives a performance advantage, although it is a bit more complicated, because it requires a synchronization mechanism.

Below are the sequence diagrams of the application startup and rendering.

How to build on Linux x64

1. Open the sdk_sample_qml_gl.pro file in Qt Creator (c)
2. Configure project
3. Add Addition arguments: BUILDTYPE=Debug_x64 or Release_x64 depending on the build configuration. See below:
