GLKSkyboxEffect
A simple skybox visual effect for use in shader-based OpenGL rendering.
Declaration
class GLKSkyboxEffectOverview
The GLKSkyboxEffect provides a standard skybox effect for your application. Unlike the GLKBaseEffect class, the skybox does not require your application to configure and submit vertex data. Instead, it creates its own vertex data based on the configuration data you supply.
At initialization time, your application first creates a compatible context and makes it current. Then, it creates new skybox effect, configures its properties, and calls its prepareToDraw() method. Binding the effect causes a shader to be compiled and bound to the current context.
At rendering time, your application calls the effect’s prepareToDraw() method to prepare the effect and then calls its draw() method to draw the sky box.
