Class ExtShaderProgram

  • All Implemented Interfaces:
    com.badlogic.gdx.utils.Disposable
    Direct Known Subclasses:
    TessellationShaderProgram
    public class ExtShaderProgram
extends java.lang.Object
implements com.badlogic.gdx.utils.Disposable

    A shader program encapsulates a vertex and fragment shader pair linked to form a shader program.

    After construction a ShaderProgram can be used to draw Mesh. To make the GPU use a specific ShaderProgram the programs begin() method must be used which effectively binds the program.

    When a ShaderProgram is bound one can set uniforms, vertex attributes and attributes as needed via the respective methods.

    A ShaderProgram can be unbound with a call to end()

    A ShaderProgram must be disposed via a call to dispose() when it is no longer needed

    ShaderPrograms are managed. In case the OpenGL context is lost all shaders get invalidated and have to be reloaded. This happens on Android when a user switches to another application or receives an incoming call. Managed ShaderPrograms are automatically reloaded when the OpenGL context is recreated so you don't have to do this manually.
