Method Detail

getFragmentShader

public java.lang.String[] getFragmentShader(java.lang.Object sh)

Specified by:

getFragmentShader in class GLSLShader

Returns:

getInstance

public GLSLShader getInstance()

Description copied from class: GLSLShader

For "hardcompiled" Shaders this method should return a new instance

Overrides:

getInstance in class GLSLShader

Returns:

getLightFunction

public java.lang.String getLightFunction()

Description copied from class: GLSLLightShader

Sets middle part of a light shader (after properties have been extracted from deferred-shading-textures

Overrides:

getLightFunction in class GLSLLightShader

Returns:

instanceFor

public java.lang.Class instanceFor()

Overrides:

instanceFor in class GLSLShader

Returns:

Class represented by this Shader

needsRecompilation

public boolean needsRecompilation(java.lang.Object data)

Description copied from class: GLSLShader

Return false if Shader depends only on Uniforms

Overrides:

needsRecompilation in class GLSLShader

Returns:

true, if Sourcecode needs to be regenerated and recompiled

setupDynamicUniforms

public 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 GLSLLightShader

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 data)

Overrides:
