Package com.badlogic.gdx.graphics.glutils

Class CustomTexture3DData

java.lang.Object

com.badlogic.gdx.graphics.glutils.CustomTexture3DData

All Implemented Interfaces:

Texture3DData

public class CustomTexture3DData
extends java.lang.Object
implements Texture3DData

A Texture3DData implementation that addresses 2 use cases : You can use it as a GL only texture (feed by a compute shader). In this case the texture is not managed. Or you can use it to upload pixels to GPU. In this case you should call getPixels() to fill the buffer prior to consuming it (eg. before new Texture3D(data)).

Method Detail

isPrepared

public boolean isPrepared()

Specified by:

isPrepared in interface Texture3DData

Returns:

whether the TextureData is prepared or not.

prepare

public void prepare()

Description copied from interface: Texture3DData

Prepares the TextureData for a call to Texture3DData.consume3DData(). This method can be called from a non OpenGL thread and should thus not interact with OpenGL.

Specified by:

prepare in interface Texture3DData

getWidth

public int getWidth()

Specified by:

getWidth in interface Texture3DData

Returns:

the width of this Texture3D

getHeight

public int getHeight()

Specified by:

getHeight in interface Texture3DData

Returns:

the height of this Texture3D

getDepth

public int getDepth()

Specified by:

getDepth in interface Texture3DData

Returns:

the depth of this Texture3D

useMipMaps

public boolean useMipMaps()

Specified by:

useMipMaps in interface Texture3DData

Returns:

whether to generate mipmaps or not.

isManaged

public boolean isManaged()

Specified by:

isManaged in interface Texture3DData

Returns:

whether this implementation can cope with a EGL context loss.

getInternalFormat

public int getInternalFormat()

Specified by:

getInternalFormat in interface Texture3DData

Returns:

the internal format of this Texture3D

getGLType

public int getGLType()

Specified by:

getGLType in interface Texture3DData

Returns:

the GL type of this Texture3D

getGLFormat

public int getGLFormat()

getMipMapLevel

public int getMipMapLevel()

getPixels

public java.nio.ByteBuffer getPixels()

consume3DData

public void consume3DData()

Description copied from interface: Texture3DData

Uploads the pixel data to the OpenGL ES texture. The caller must bind an OpenGL ES texture. A call to Texture3DData.prepare() must preceed a call to this method. Any internal data structures created in Texture3DData.prepare() should be disposed of here.

Specified by:

consume3DData in interface Texture3DData
