Class BaseShader

java.lang.Object
  com.badlogic.gdx.graphics.g3d.shaders.BaseShader

All Implemented Interfaces:

Shader, Disposable

Direct Known Subclasses:

DefaultShader

public abstract class BaseShader
extends Object
implements Shader

Author:

Xoppa A BaseShader is a wrapper around a ShaderProgram that keeps track of the uniform and attribute locations. It does not manage the ShaderPogram, you are still responsible for disposing the ShaderProgram.

Register an uniform which might be used by this shader. Only possible prior to the call to init().

Returns:

The ID of the uniform to use in this shader.

getUniformID

public int getUniformID(String alias)

Returns:

the ID of the input or negative if not available.

getUniformAlias

public String getUniformAlias(int id)

Returns:

The input at the specified id.

init

public void init(ShaderProgram program,
                 Renderable renderable)

Initialize this shader, causing all registered uniforms/attributes to be fetched.

begin
