Description:

[ Deprecated ( since = "1.8" ) ]
public class Shader : Object

Warning: Shader is deprecated.

The Shader structure contains only private data

Namespace: Clutter

Package: clutter-1.0

Content:

Properties:

public bool compiled { get; }
Whether the shader is compiled and linked, ready for use in the GL context.
public bool enabled { set; get; }
Whether the shader is currently used in the GL rendering pipeline.
public string fragment_source { set; owned get; }
GLSL source code for the fragment shader part of the shader program.
public string vertex_source { set; owned get; }
GLSL source code for the vertex shader part of the shader program, if any

Creation methods:

public Shader ()
Create a new Shader instance.

Methods:

public bool compile () throws Error
Compiles and links GLSL sources set for vertex and fragment shaders for a Shader. If the compilation fails and a Error return location is provided the error will contain the errors from the compiler, if any.
public weak Handle get_cogl_fragment_shader ()
Retrieves the underlying VertexBufferIndices for the fragment shader.
public weak Handle get_cogl_program ()
Retrieves the underlying VertexBufferIndices for the shader program.
public weak Handle get_cogl_vertex_shader ()
Retrieves the underlying VertexBufferIndices for the vertex shader.
public unowned string get_fragment_source ()
Query the current GLSL fragment source set on shader.
public bool get_is_enabled ()
Checks whether shader is enabled.
public unowned string get_vertex_source ()
Query the current GLSL vertex source set on shader.
public bool is_compiled ()
Checks whether shader is is currently compiled, linked and bound to the GL context.
public void release ()
Frees up any GL context resources held by the shader.
public void set_fragment_source (string data, ssize_t length)
Sets the GLSL source code to be used by a Shader for the fragment program.
public void set_is_enabled (bool enabled)
Enables a shader. This function will attempt to compile and link the shader, if it isn't already.
public void set_uniform (string name, Value value)
Sets a user configurable variable in the GLSL shader programs attached to a Shader.
public void set_vertex_source (string data, ssize_t length)
Sets the GLSL source code to be used by a Shader for the vertex program.
