public static void glBindBuffer(int target,
                                int buffer)

`ARRAY_BUFFER`	`ELEMENT_ARRAY_BUFFER`	`PIXEL_PACK_BUFFER`	`PIXEL_UNPACK_BUFFER`
`TRANSFORM_FEEDBACK_BUFFER`	`UNIFORM_BUFFER`	`TEXTURE_BUFFER`	`COPY_READ_BUFFER`

glGenBuffers
```
public static int glGenBuffers()
```
OpenGL SDK Reference
Generates buffer object names.

glIsBuffer
```
public static boolean glIsBuffer(int buffer)
```
OpenGL SDK Reference
Determines if a name corresponds to a buffer object.

Parameters:

glBufferData

public static void glBufferData(int target,
                                long size,
                                int usage)

OpenGL SDK Reference

Creates and initializes a buffer object's data store.

usage is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store. usage can be broken down into two parts: first, the frequency of access (modification and usage), and second, the nature of that access. The frequency of access may be one of these:

STREAM - The data store contents will be modified once and used at most a few times.
STATIC - The data store contents will be modified once and used many times.
DYNAMIC - The data store contents will be modified repeatedly and used many times.

The nature of access may be one of these:

DRAW - The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.
READ - The data store contents are modified by reading data from the GL, and used to return that data when queried by the application.
COPY - The data store contents are modified by reading data from the GL, and used as the source for GL drawing and image specification commands.

Parameters:

target - the target buffer object. One of:

`ARRAY_BUFFER`	`ELEMENT_ARRAY_BUFFER`	`PIXEL_PACK_BUFFER`	`PIXEL_UNPACK_BUFFER`
`TRANSFORM_FEEDBACK_BUFFER`	`UNIFORM_BUFFER`	`TEXTURE_BUFFER`	`COPY_READ_BUFFER`
`COPY_WRITE_BUFFER`	`DRAW_INDIRECT_BUFFER`	`ATOMIC_COUNTER_BUFFER`	`DISPATCH_INDIRECT_BUFFER`
`SHADER_STORAGE_BUFFER`	`PARAMETER_BUFFER_ARB`

size - the size in bytes of the buffer object's new data store

usage - the expected usage pattern of the data store. One of:

`STREAM_DRAW`	`STREAM_READ`	`STREAM_COPY`	`STATIC_DRAW`	`STATIC_READ`	`STATIC_COPY`	`DYNAMIC_DRAW`
`DYNAMIC_READ`	`DYNAMIC_COPY`

OpenGL SDK Reference

Maps a buffer object's data store.

LWJGL note: This method comes in 3 flavors:

GL15.glMapBuffer(int, int) - Calls GetBufferParameteriv to retrieve the buffer size and a new ByteBuffer instance is always returned.
GL15.glMapBuffer(int, int, ByteBuffer) - Calls GetBufferParameteriv to retrieve the buffer size and the old_buffer parameter is reused if not null.
GL15.glMapBuffer(int, int, long, ByteBuffer) - The buffer size is explicitly specified and the old_buffer parameter is reused if not null. This is the most efficient method.

Parameters:

target - the target buffer object being mapped. One of:

`ARRAY_BUFFER`	`ELEMENT_ARRAY_BUFFER`	`PIXEL_PACK_BUFFER`	`PIXEL_UNPACK_BUFFER`
`TRANSFORM_FEEDBACK_BUFFER`	`UNIFORM_BUFFER`	`TEXTURE_BUFFER`	`COPY_READ_BUFFER`
`COPY_WRITE_BUFFER`	`DRAW_INDIRECT_BUFFER`	`ATOMIC_COUNTER_BUFFER`	`DISPATCH_INDIRECT_BUFFER`
`SHADER_STORAGE_BUFFER`	`PARAMETER_BUFFER_ARB`

access - the access policy, indicating whether it will be possible to read from, write to, or both read from and write to the buffer object's mapped data store. One of:

READ_ONLY

WRITE_ONLY

READ_WRITE

glUnmapBuffer

public static boolean glUnmapBuffer(int target)

OpenGL SDK Reference

Relinquishes the mapping of a buffer object and invalidates the pointer to its data store.

Returns TRUE unless data values in the buffer’s data store have become corrupted during the period that the buffer was mapped. Such corruption can be the result of a screen resolution change or other window system-dependent event that causes system heaps such as those for high-performance graphics memory to be discarded. GL implementations must guarantee that such corruption can occur only during the periods that a buffer’s data store is mapped. If such corruption has occurred, UnmapBuffer returns FALSE, and the contents of the buffer’s data store become undefined.

Parameters:

target - the target buffer object being unmapped. One of:

`ARRAY_BUFFER`	`ELEMENT_ARRAY_BUFFER`	`PIXEL_PACK_BUFFER`	`PIXEL_UNPACK_BUFFER`
`TRANSFORM_FEEDBACK_BUFFER`	`UNIFORM_BUFFER`	`TEXTURE_BUFFER`	`COPY_READ_BUFFER`
`COPY_WRITE_BUFFER`	`DRAW_INDIRECT_BUFFER`	`ATOMIC_COUNTER_BUFFER`	`DISPATCH_INDIRECT_BUFFER`
`SHADER_STORAGE_BUFFER`	`PARAMETER_BUFFER_ARB`

glGetBufferParameteriv

public static void glGetBufferParameteriv(int target,
                                          int pname,
                                          java.nio.IntBuffer params)

OpenGL SDK Reference

Returns the value of a buffer object parameter.

Parameters:

target - the target buffer object. One of:

`ARRAY_BUFFER`	`ELEMENT_ARRAY_BUFFER`	`PIXEL_PACK_BUFFER`	`PIXEL_UNPACK_BUFFER`
`TRANSFORM_FEEDBACK_BUFFER`	`UNIFORM_BUFFER`	`TEXTURE_BUFFER`	`COPY_READ_BUFFER`
`COPY_WRITE_BUFFER`	`DRAW_INDIRECT_BUFFER`	`ATOMIC_COUNTER_BUFFER`	`DISPATCH_INDIRECT_BUFFER`
`SHADER_STORAGE_BUFFER`	`PARAMETER_BUFFER_ARB`

pname - the symbolic name of a buffer object parameter. One of:

`BUFFER_SIZE`	`BUFFER_USAGE`	`BUFFER_ACCESS`	`BUFFER_MAPPED`
