CachedShaderCollection

public CachedShaderCollection()

Method Details

getCacheEntry

public GLSLManagedShader getCacheEntry(OpenGLState glState,
 GLSLDisplay disp,
 ShaderConfiguration sc,
 Object s)

Retrieve the cached entry for a Configuration/Object-Pair. If no entry exists method will generate and store a new one

Parameters:

sc -

s -

Returns:

the fetched managed Shader

findAndActivateShader

public void findAndActivateShader(OpenGLState glState,
 GLSLDisplay disp,
 ShaderConfiguration sc,
 Shader s)

Will obtain and activate a GLSLShader to emulate the input shaders behavior. Will cache instances of GLSLShaders inside shaderCache

Parameters:

glState - current GL instance

disp - active GLDisplay instance

s - shader that should be activated

findShader

public GLSLManagedShader findShader(OpenGLState glState,
 GLSLDisplay disp,
 ShaderConfiguration sc,
 Shader s)

Will obtain a GLSLShader to emulate the input shaders behavior. Will cache instances of GLSLShaders inside shaderCache

Parameters:

glState - current GL instance

disp - active GLDisplay instance

s - shader that should be activated

setCurrentStamp

public void setCurrentStamp(int stamp)

removeUnusedShaders

public void removeUnusedShaders(OpenGLState glState)

Removes unused GLSLShaders from shaderCache

Parameters:

glState -

getCurrentShader

public GLSLManagedShader getCurrentShader()

Get current active GLSLShader. Will only work for managed Shaders. If a non managed Shader is active result is undefined.

Returns:

returns active shader as corresponding GLSLShaderManagedShader

deleteAll

public void deleteAll(OpenGLState glState,
 boolean javaonly)

Remove all compiled Shaders from shaderCache and shaderMap.

Parameters:

glState -
