Class ARBTextureBufferRange

java.lang.Object

org.lwjgl.opengl.ARBTextureBufferRange

public class ARBTextureBufferRange
extends java.lang.Object

Native bindings to the ARB_texture_buffer_range extension.

ARB_texture_buffer_object (which was promoted to core in OpenGL 3.1) introduced the ability to attach the data store of a buffer object to a buffer texture and access it from shaders. The extension only allows the entire store of the buffer object to the texture. This extension expands on this and allows a sub-range of the buffer's data store to be attached to a texture. This can be used, for example, to allow multiple buffer textures to be backed by independent sub-ranges of the same buffer object, or for different sub-ranges of a single buffer object to be used for different purposes.

Requires OpenGL 1.5. Promoted to core in OpenGL 4.3.

Method Detail

glTexBufferRange

public static void glTexBufferRange(int target,
                                    int internalformat,
                                    int buffer,
                                    long offset,
                                    long size)

Binds a range of a buffer's data store to a buffer texture.

Parameters:

target - the target of the operation. Must be:

TEXTURE_BUFFER

internalformat - the internal format of the data in the store belonging to buffer

buffer - the name of the buffer object whose storage to attach to the active buffer texture

offset - the offset of the start of the range of the buffer's data store to attach

size - the size of the range of the buffer's data store to attach

glTextureBufferRangeEXT

public static void glTextureBufferRangeEXT(int texture,
                                           int target,
                                           int internalformat,
                                           int buffer,
                                           long offset,
                                           long size)

DSA version of TexBufferRange.

Parameters:

texture - the texture object

target - the target of the operation. Must be:

TEXTURE_BUFFER

internalformat - the internal format of the data in the store belonging to buffer

buffer - the name of the buffer object whose storage to attach to the active buffer texture

offset - the offset of the start of the range of the buffer's data store to attach

size - the size of the range of the buffer's data store to attach
