Modifier and Type	Method	Description
void	allocate(ImageBuffer textureBuffer)	Allocates and binds the buffer (links it to the GL_FRAMEBUFFER OpenGL target).
void	bind()	Binds this buffer to the OpenGL context (binding points of GPU rendering pipeline), so it become visible for shaders.

Constructor Details

FrameBufferImpl

public FrameBufferImpl(BufferDef bufferDef,
 com.jogamp.opengl.GLContext glContext)

Constructor.

Parameters:

bufferDef - Buffer name

glContext - OpenGL context

Method Details

allocate

public void allocate(ImageBuffer textureBuffer)

Description copied from interface: FrameBuffer

Allocates and binds the buffer (links it to the GL_FRAMEBUFFER OpenGL target).

Specified by:

allocate in interface FrameBuffer

Parameters:

textureBuffer - Existing texture buffer whose image is to be attached

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
