Constructor Details

ImageBufferImpl

public ImageBufferImpl(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 width,
 int height,
 int format,
 int type,
 int filter)

Description copied from interface: ImageBuffer

Allocates the buffer using glTexImage2D OpenGL method

Specified by:

allocate in interface ImageBuffer

Parameters:

width - glTexImage2D() width parameter

height - glTexImage2D() height parameter

format - glTexImage2D() format parameter

type - glTexImage2D() format parameter

filter - Filtering mode

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

clear

public void clear(long val)

Description copied from interface: ImageBuffer

Clear the buffer with given value.

Specified by:

clear in interface ImageBuffer

Parameters:

val - Value
