GLSLShader

public GLSLShader(OpenGLState glState)

Method Details

printProgramInfoLog

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

Same as printShaderInfoLog only for Programs.

Parameters:

gl -

program -

getShaderProgramNumber

public int getShaderProgramNumber()

Getter for Shader Programnumber

Returns:

the OpenGL id of the associated shader-program-id

needsRecompilation

public boolean needsRecompilation(Object data)

Return false if Shader depends only on Uniforms

Parameters:

s - Associated Shader

Returns:

true, if Sourcecode needs to be regenerated and recompiled

instanceFor

public Class instanceFor()

Returns:

Class represented by this Shader

getInstance

public GLSLShader getInstance()

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

Returns:

getVertexShader

protected String[] getVertexShader(Object data)

Parameters:

sh -

Returns:

getFragmentShader

protected abstract String[] getFragmentShader(Object data)

Parameters:

sh -

Returns:

setupDynamicUniforms

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

Parameters:

gl -

disp -

s -

activateShader

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

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

Parameters:

disp -

gl -

sh -

s -

deleteShader

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

Remove OpenGL side of this shader

Parameters:

gl -
