Unigine Integration into SDL Application

This article describes the sample located in the <UnigineSDK>/source/samples/App/GLAppSDL/ folder.

The sample demonstrates how to embed Unigine into an SDL-based application, namely:

• Create a simple SDL-based application
• Integrate Unigine into the application
• Initialize the OpenGL mode

In this sample, the engine controls the main loop by itself: the doUpdate(), doRender() and doSwap() functions are overridden and call the update(), render() and swap() functions respectively.

To run the sample, you should perform the following:

1. Download development libraries from the SDL website.
   Notice

   Only SDL version 1.2 is supported.
2. Extract the downloaded compressed folder and place it into the sample folder.
3. Change the path to the SDL.h header file in the GLAppSDL.cpp if necessary. For example:
   Source code (C++)

   #include "SDL/include/SDL.h"

   Notice

   By default, the SDL/SDL.h path is used.
4. Prepare the development environment (according to the operating system used).
5. Specify paths to the SDL/include/ and SDL/lib/x86 (or SDL/lib/x64) folders in your IDE.
6. Rebuild the sample (see how to rebuild a sample application in Windows or Linux)
7. Run the main.py script from the sample folder.
