abstract interface IBuffer;
Interface every buffer implements
class ElementBuffer: glamour.vbo.IBuffer;
Represents an OpenGL element buffer. The constructor must be used to avoid segmentation faults.
GLuint buffer;
The OpenGL buffer name.
GLenum hint;
Specifies the expected usage pattern of the data store.
size_t length;
Length of the passed data, note it's the length of a void[] array.
this()();
Initializes the buffer.
this(T)(auto ref const T data, GLenum hint = GL_STATIC_DRAW);
this(T)(const T ptr, size_t size, GLenum hint = GL_STATIC_DRAW);
Initualizes the buffer and sets data.
void remove();
Deletes the buffer.
void bind();
Binds the buffer.
void unbind();
Unbinds the buffer.
void set_data(T)(auto ref const T data, GLenum hint = GL_STATIC_DRAW);
void set_data(T)(const T ptr, size_t size, GLenum hint = GL_STATIC_DRAW);
Uploads data to the GPU.

- Parameters
data any kind of data. type OpenGL type of the data (e.g. GL_FLOAT) hint Specifies the expected usage pattern of the data store.
Initualizes the buffer and sets data.
void remove();
Deletes the buffer.
void bind();
Binds the buffer.
void bind(GLint attrib_location, GLenum type, GLint size, GLsizei offset, GLsizei stride, GLboolean normalized = GL_FALSE);
void bind(Shader shader, string location, GLenum type, GLint size, GLsizei offset, GLsizei stride, GLboolean normalized = GL_FALSE);
- Parameters
GLenum type Specifies the data type of each component in the array. GLint size Specifies the number of components per generic vertex attribute. GLsizei offset Specifies a offset of the first component of the first generic vertex attribute in the array in the data store of the buffer. GLsizei stride Specifies the byte offset between consecutive generic vertex attributes. GLboolean normalized Specifies whether fixed-point data values should be normalized (GL_TRUE) or converted directly as fixed-point values (GL_FALSE = default) when they are accessed.
Binds the buffer and sets the vertex attrib pointer.
void unbind();
Unbinds the buffer.
void set_data(T)(auto ref const T data, GLenum hint = GL_STATIC_DRAW);
void set_data(T)(const T ptr, size_t size, GLenum hint = GL_STATIC_DRAW);
Uploads data to the GPU.
void update(T)(ref const T data, GLintptr offset);
void update(T)(const T ptr, size_t size, GLintptr offset);
Updates the Buffer, using glBufferSubData.
