Module pyglet.graphics.vertexbuffer

Byte abstractions of Vertex Buffer Objects and vertex arrays.

Use create_buffer or create_mappable_buffer to create a Vertex Buffer Object, or a vertex array if VBOs are not supported by the current context.

Buffers can optionally be created "mappable" (incorporating the AbstractMappable mix-in). In this case the buffer provides a get_region method which provides the most efficient path for updating partial data within the buffer.

Classes

	AbstractBuffer Abstract buffer of byte data.
	AbstractMappable
	VertexArray A ctypes implementation of a vertex array.
	VertexBufferObject Lightweight representation of an OpenGL VBO.
	MappableVertexBufferObject A VBO with system-memory backed store.
	AbstractBufferRegion A mapped region of a buffer.
	VertexBufferObjectRegion A mapped region of a VBO.
	VertexArrayRegion A mapped region of a vertex array.
	IndirectArrayRegion A mapped region in which data elements are not necessarily contiguous.

Function Details

create_buffer

create_buffer(size, target=34962, usage=35048, vbo=True)

Create a buffer of vertex data.

Parameters:

size : int: Size of the buffer, in bytes
target : int: OpenGL target buffer
usage : int: OpenGL usage constant
vbo : bool: True if a VertexBufferObject should be created if the driver supports it; otherwise only a VertexArray is created.

Returns: AbstractBuffer

create_mappable_buffer

create_mappable_buffer(size, target=34962, usage=35048, vbo=True)

Create a mappable buffer of vertex data.

Parameters:

size : int: Size of the buffer, in bytes
target : int: OpenGL target buffer
usage : int: OpenGL usage constant
vbo : bool: True if a VertexBufferObject should be created if the driver supports it; otherwise only a VertexArray is created.

Returns: AbstractBuffer with AbstractMappable
