Class GLSurface

java.lang.Object

icyllis.modernui.graphics.GLSurface

All Implemented Interfaces:

AutoCloseable

@Deprecated
public final class GLSurface
extends Object
implements AutoCloseable

Deprecated.

This class represents a framebuffer object. It is used for creation of user-defined framebuffers compared to the default framebuffer, whose object is a collection of attachments, for off-screen rendering or post-processing.

For post-processing, attach this to a set of textures otherwise to render buffers. To output this framebuffer to screen, draw the attached textures or copy the renderbuffer pixels to the default framebuffer that preserved by window graphics context.

Losing the reference of the object will delete the framebuffer and all attachments automatically.

Constructor Details

GLSurface

public GLSurface()

Deprecated.

Creates a framebuffer.

Method Details

get

public int get()

Deprecated.

bind

public void bind()

Deprecated.

Binds this framebuffer object to both draw and read target.

bindDraw

public void bindDraw()

Deprecated.

bindRead

public void bindRead()

Deprecated.

clearColorBuffer

public void clearColorBuffer()

Deprecated.

Clear the current color buffer set by setDrawBuffer(int) to the color (0,0,0,0). Clear the current depth buffer to 1.0f, and stencil buffer to 0.

clearStencilBuffer

public void clearStencilBuffer()

Deprecated.

setDrawBuffer

public void setDrawBuffer(int buffer)

Deprecated.

Set the color buffer for layout(location = 0) out vec4 fragColor. That means the color buffer index is 0.

Note that only GL_COLOR_ATTACHMENT[x] or GL_NONE is accepted by a framebuffer object. Values such as GL_FRONT_LEFT, GL_BACK are only accepted by the default framebuffer (reserved by the window).

Parameters:

buffer - enum buffer

setReadBuffer

public void setReadBuffer(int buffer)

Deprecated.

getBackingWidth

public int getBackingWidth()

Deprecated.

getBackingHeight

public int getBackingHeight()

Deprecated.

getAttachedTexture

@Nonnull
public GLTexture getAttachedTexture(int attachment)

Deprecated.

Returns the attached texture with the given attachment point.

Parameters:

attachment - specify an attachment point

Returns:

the raw ptr to texture

Throws:

NullPointerException - attachment is not a texture or detached

makeBuffers

public void makeBuffers(int width,
 int height,
 boolean exact)

Deprecated.

close

public void close()

Deprecated.

Specified by:

close in interface AutoCloseable
