Method Detail

getAllChannels

protected abstract Result[] getAllChannels(java.lang.Object sha)

getFragmentShader

protected java.lang.String[] getFragmentShader(java.lang.Object sha)

Generate the FragmentShaderCode by using the configuration of the Shader.

Specified by:

getFragmentShader in class GLSLShader

Returns:

isOpaque

public boolean isOpaque(java.lang.Object s)

mayDiscard

public boolean mayDiscard(java.lang.Object s)

Parameters:

s - GroImp Shader that acts as a base for this shader

Returns:

True, if fragments may be discarded by this shader

setupDynamicUniforms

protected void setupDynamicUniforms(javax.media.opengl.GL gl,
                                    GLSLDisplay disp,
                                    java.lang.Object data,
                                    int shaderNo)

Description copied from class: GLSLShader

Function that loads uniforms of the represented Shader.

Overrides:

setupDynamicUniforms in class GLSLShader

disp - GLSLDisplay that tries using this shader

data - The GroIMP-Shader-Object represented by this shader.

setupShader

protected void setupShader(javax.media.opengl.GL gl,
                           GLSLDisplay disp,
                           java.lang.Object s)

Overrides:

setupShader in class GLSLShader

setupUniforms

protected void setupUniforms(javax.media.opengl.GL gl,
                             GLSLDisplay disp,
                             java.lang.Object s,
                             int shaderProgramNumber)

Function that loads uniforms of the represented Shader. Called by setupShader(GL, GLSLDisplay, Object). Use this to add special uniforms instead of overloading setupShader(GL, GLSLDisplay, Object). Used by SideSwitchShader to initialize both shaders.

Parameters:

gl -

disp - GLSLDisplay that tries using this shader

s - The GroIMP-Shader-Object represented by this shader.
