To create a basic application:

-

To develop a GL application, you have to call elm_config_accel_preference_set before creating a window. It makes an application to use GPU. To use the Direct Rendering mode, you have to set the same option values (depth, stencil, and MSAA) to a rendering engine and a GLView object. You can set the option values to a rendering engine using the elm_config_accel_preference_set() function and to a GLView object using the elm_glview_mode_set() function. If the GLView object option values are bigger or higher than the rendering engine's, the Direct Rendering mode is disabled.

To develop a GL application, you have to call elm_config_accel_preference_set before creating a window. It makes an application to use GPU. To use the Direct Rendering mode since Tizen 2.4, you have to set the same option values (depth, stencil, and MSAA) to a rendering engine and a GLView object. You can set the option values to a rendering engine using the elm_config_accel_preference_set() function and to a GLView object using the elm_glview_mode_set() function. If the GLView object option values are bigger or higher than the rendering engine's, the Direct Rendering mode is disabled.

First, you should declare the global variable using ELEMENTARY_GLVIEW_GLOBAL_DEFINE(), then create a GLView object and use ELEMENTARY_GLVIEW_GLOBAL_USE(glview). Now, you can call GL functions.
