Field Details

prependControlCode

public static String prependControlCode

Code that is always added to the tessellation shaders, typically used to inject a #version line. Note that this is added as-is, you should include a newline (`\n`) if needed.

prependEvaluationCode

public static String prependEvaluationCode

controlShaderFile

protected String controlShaderFile

evaluationShaderFile

protected String evaluationShaderFile

Constructor Details

TessellationShaderProgram

public TessellationShaderProgram(String vertexShaderCode,
 String controlShaderCode,
 String evaluationShaderCode,
 String fragmentShaderCode)

TessellationShaderProgram

public TessellationShaderProgram(String name,
 String vertexFile,
 String tessControlFile,
 String tessEvaluationFile,
 String fragmentFile,
 String vertexShaderCode,
 String controlShaderCode,
 String evaluationShaderCode,
 String fragmentShaderCode,
 boolean lazyLoading)

Constructs a new shader program and immediately compiles it, if it is not lazy.

Parameters:

name - The shader name, if any.

vertexFile - The vertex shader file.

tessControlFile - The tessellation control shader file.

tessEvaluationFile - The tessellation evaluation shader file.

fragmentFile - The fragment shader file.

vertexShaderCode - The vertex shader code.

controlShaderCode - The tessellation control shader code.

evaluationShaderCode - The tessellation evaluation shader code.

fragmentShaderCode - The fragment shader code.

lazyLoading - Whether to use lazy loading, only preparing the data without actually compiling the shaders.

Method Details

compile

public void compile()

Overrides:

compile in class ExtShaderProgram

invalidateAllShaderPrograms

public static void invalidateAllShaderPrograms(com.badlogic.gdx.Application app)

Invalidates all shaders so the next time they are used new handles are generated

clearAllShaderPrograms

public static void clearAllShaderPrograms(com.badlogic.gdx.Application app)

getManagedStatus

public static String getManagedStatus()

getNumManagedShaderPrograms

public static int getNumManagedShaderPrograms()

Returns:

the number of managed shader programs currently loaded

getControlShaderSource

public String getControlShaderSource()

getControlShaderFileName

public String getControlShaderFileName()

getEvaluationShaderSource

public String getEvaluationShaderSource()

getEvaluationShaderFileName

public String getEvaluationShaderFileName()

dispose

public void dispose()

Description copied from class: ExtShaderProgram

Disposes all resources associated with this shader. Must be called when the shader is no longer used.

Specified by:

dispose in interface com.badlogic.gdx.utils.Disposable

Overrides:

dispose in class ExtShaderProgram
