Description

A OpenCL image2d for accessing an OpenGL texture object.

opengl_texture public construct/copy/destruct

  1. opengl_texture();
    Creates a null OpenGL texture object.
  2. explicit opengl_texture(cl_mem mem, bool retain = true);
    Creates a new OpenGL texture object for mem.
  3. opengl_texture(const context & context, GLenum texture_target, GLint miplevel, 
                   GLuint texture, cl_mem_flags flags = read_write);

    Creates a new OpenGL texture object in context for texture with flags.

    See the documentation for

  4. opengl_texture(const opengl_texture & other);
    Creates a new OpenGL texture object as a copy of other.
  5. opengl_texture & operator=(const opengl_texture & other);
    Copies the OpenGL texture object from other.
  6. ~opengl_texture();
    Destroys the texture object.

opengl_texture public member functions

  1. extents< 2 > size() const;
    Returns the size (width, height) of the texture.
  2. extents< 2 > origin() const;
    Returns the origin of the texture (0, 0).
  3. template<typename T> T get_texture_info(cl_gl_texture_info info) const;

    Returns information about the texture.
