Description:

Content:

Properties:

• public bool compiled { get; }
  Whether the shader is compiled and linked, ready for use in the GL context.
• public bool enabled { get; set; }
  Whether the shader is currently used in the GL rendering pipeline.
• public string fragment_source { owned get; set; }
  GLSL source code for the fragment shader part of the shader program.
• public string vertex_source { owned get; set; }
  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.
• public unowned Handle get_cogl_fragment_shader ()
  Retrieves the underlying VertexBufferIndices for the fragment shader.
• public unowned Handle get_cogl_program ()
  Retrieves the underlying VertexBufferIndices for the shader program.
• public unowned 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 this.
• public bool get_is_enabled ()
  Checks whether this is enabled.
• public unowned string get_vertex_source ()
  Query the current GLSL vertex source set on this.
• public bool is_compiled ()
  Checks whether this 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.
• 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.
