public class TextureBufferImpl
extends AbstractBuffer
implements TextureBuffer

A texture buffer backed by another buffer. This buffer is used for the GL_TEXTURE_BUFFER OpenGL target.

Constructor Details

TextureBufferImpl

public TextureBufferImpl(BufferDef bufferName,
 com.jogamp.opengl.GLContext glContext,
 int internalFormat,
 int access)

Constructor.

Parameters:

bufferName - Buffer name

glContext - OpenGL context

internalFormat - The format parameter of the glBindImageTexture function and internalFormat of the glTexBuffer and glTexImage2D functions

access - The access parameter of the glBindImageTexture function

Method Details

allocate

public void allocate(int filter,
 int dataObject)

Description copied from interface: TextureBuffer

Allocates the buffer using glTexBuffer OpenGL method

Specified by:

allocate in interface TextureBuffer

Parameters:

filter - Filtering mode

dataObject - name of the buffer object which data store gets attached to the texture object

bind

public void bind()

Description copied from interface: GlslBuffer

Binds this buffer to the OpenGL context (binding points of GPU rendering pipeline), so it become visible for shaders. Buffers can be bound to their binding points even unallocated. Do not use this method directly. As every buffer should be included in a GlslBufferGroup, use GlslBufferGroup.bindBuffer(cz.fidentis.analyst.glsl.buffers.BufferDef) to bind buffers individually or GlslBufferGroup.bindSsboBuffers() to allocate all SSBO buffers at once.

Specified by:

bind in interface GlslBuffer
