Method Detail

activateShader

public void activateShader(OpenGLState glState,
                  GLSLDisplay disp,
                  java.lang.Object data)

Only public method. Use this to activate (and compile) this Shader for use in rendering.

Parameters:

gl -

disp -

sh -

s -

cleanup

public void cleanup(OpenGLState glState,
           boolean javaonly)

Specified by:

cleanup in interface GLSLOpenGLObject

deleteShader

public void deleteShader(javax.media.opengl.GL gl,
                boolean javaonly)

Remove OpenGL side of this shader

Parameters:

gl -

getFragmentShader

protected abstract java.lang.String[] getFragmentShader(java.lang.Object data)

Parameters:

sh -

Returns:

getInstance

public GLSLShader getInstance()

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

Returns:

getShaderProgramNumber

public int getShaderProgramNumber()

Getter for Shader Programnumber

Returns:

the OpenGL id of the associated shader-program-id

getVertexShader

protected java.lang.String[] getVertexShader(java.lang.Object data)

Parameters:

sh -

Returns:

instanceFor

public java.lang.Class instanceFor()

Returns:

Class represented by this Shader

needsRecompilation

public boolean needsRecompilation(java.lang.Object data)

Return false if Shader depends only on Uniforms

Parameters:

s - Associated Shader

Returns:

true, if Sourcecode needs to be regenerated and recompiled

printProgramInfoLog

protected static void printProgramInfoLog(javax.media.opengl.GL gl,
                       int program)

Same as printShaderInfoLog only for Programs.

Parameters:

gl -

program -

setupDynamicUniforms

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

Function that loads uniforms of the represented Shader.

Parameters:

gl -

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)

Parameters:

gl -

disp -

s -
