public GLSLRGBAShader()

Method Details

getAllChannels

protected Result[] getAllChannels(Object sha)

Specified by:

getAllChannels in class GLSLMaterial

getInstance

public GLSLManagedShader getInstance()

Description copied from class: GLSLShader

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

Overrides:

getInstance in class GLSLShader

Returns:

instanceFor

public Class instanceFor()

Overrides:

instanceFor in class GLSLShader

Returns:

Class represented by this Shader

setupUniforms

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

Description copied from class: GLSLMaterial

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

Overrides:

setupUniforms in class GLSLMaterial

Parameters:

gl -

disp - GLSLDisplay that tries using this shader

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

setupDynamicUniforms

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

Description copied from class: GLSLShader

Function that loads uniforms of the represented Shader.

Overrides:

setupDynamicUniforms in class GLSLMaterial

Parameters:

gl -

disp - GLSLDisplay that tries using this shader

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

needsRecompilation

public boolean needsRecompilation(Object s)

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

isOpaque

public boolean isOpaque(Object s)

Overrides:

isOpaque in class GLSLMaterial
