Class | public final class CubeTexture |
Inheritance | CubeTexture ![]() ![]() ![]() |
Defines a cube map texture for use during rendering. Cube mapping is used for many rendering techniques, such as environment maps, skyboxes, and skylight illumination.
You cannot create a CubeTexture object directly; use the
Context3D createCubeTexture()
instead.

uploadCompressedTextureFromByteArray | () | method |
public function uploadCompressedTextureFromByteArray(data:ByteArray, byteArrayOffset:uint, async:Boolean = false):void
Language version: | ActionScript 3.0 |
Runtime version: | AIR 3 |
Uploads a cube texture in Adobe Texture Format (ATF) from a byte array.
The byte array must contain all faces and mipmaps for the texture.
Parametersdata:ByteArray — a byte array that containing a compressed cube texture
including mipmaps. The ByteArray object must use the little endian format.
|
|
byteArrayOffset:uint — an optional offset at which to start reading the
texture data.
|
|
async:Boolean (default = false ) — If true, this function returns immediately. Any draw method
which attempts to use the texture will fail until the upload completes successfully. Upon successful
upload, this CubeTexture object dispatches Event.TEXTURE_READY .
Default value: false.
|
TypeError — Null Pointer Error: when data is null.
|
|
ArgumentError — Texture Decoding Failed: when the compression format of this object cannot be
derived from the format of the compressed data in data .
|
|
ArgumentError — Texture Needs To Be Square: when the decompressed texture does not have
equal width and height.
|
|
ArgumentError — Texture Size Does Not Match: when the width and height of the decompressed
texture do not equal the length of the texture's edge.
|
|
ArgumentError — Miplevel Too Large: if the mip level of the decompressed texture is greater
than that implied by the length of the texture's edge.
|
|
ArgumentError — Texture Format Mismatch: if the decoded ATF bytes don't contain a texture
compatible with this texture's format or is not a cube texture.
|
|
Error — 3768: The Stage3D API may not be used during background execution.
|
|
RangeError — Bad Input Size: when there is integer overflow of byteArrayOffset or
if byteArrayOffset + 6 is greater than the length of data , or if the
number of bytes available from byteArrayOffset to the end of the data byte array
is less than the amount of data required for ATF texture.

uploadFromBitmapData | () | method |
public function uploadFromBitmapData(source:BitmapData, side:uint, miplevel:uint = 0):void
Language version: | ActionScript 3.0 |
Runtime version: | AIR 3 |
Uploads a component of a cube map texture from a BitmapData object.
This function uploads one mip level of one side of the cube map.
Call uploadFromBitmapData()
as necessary to upload each mip level and face of the
cube map.
source:BitmapData — a bitmap.
|
|
side:uint — A code indicating which side of the cube to upload:
|
|
miplevel:uint (default = 0 ) — the mip level to be loaded, level zero being the top-level
full-resolution image. The default value is zero.
|
TypeError — Null Pointer Error: if source is null .
|
|
ArgumentError — Miplevel Too Large: if the specified mip level is greater than
that implied by the the texture's dimensions.
|
|
ArgumentError — Invalid Cube Side: if side is greater than 5.
|
|
ArgumentError — Invalid BitmapData Error: if source if the BitmapData
object does not contain a valid cube texture face. The image must be square, with sides
equal to a power of two, and the correct size for the miplevel specified.
|
|
ArgumentError — Texture Format Mismatch: if the texture format is Context3DTextureFormat.COMPRESSED or
Context3DTextureFormat.COMPRESSED_ALPHA and the code is executing on a mobile platform where runtime texture compression is not supported.
|
|
Error — 3768: The Stage3D API may not be used during background execution.

uploadFromByteArray | () | method |
public function uploadFromByteArray(data:ByteArray, byteArrayOffset:uint, side:uint, miplevel:uint = 0):void
Language version: | ActionScript 3.0 |
Runtime version: | AIR 3 |
Uploads a component of a cube map texture from a ByteArray object.
This function uploads one mip level of one side of the cube map.
Call uploadFromByteArray()
as neccessary to upload each mip level and face of the
cube map.
data:ByteArray — a byte array containing the image in the format specified when this CubeTexture object
was created. The ByteArray object must use the little endian format.
|
|
byteArrayOffset:uint — reading of the byte array starts there.
|
|
side:uint — A code indicating which side of the cube to upload:
|
|
miplevel:uint (default = 0 ) — the mip level to be loaded, level zero is the top-level,
full-resolution image.
|
TypeError — Null Pointer Error: when data is null.
|
|
ArgumentError — Miplevel Too Large: if the specified mip level is greater than that
implied by the Texture's dimensions.
|
|
RangeError — Bad Input Size: if the number of bytes available from byteArrayOffset
to the end of the data byte array is less than the amount of data required
for a texture of this mip level or if byteArrayOffset is greater than or equal to the length of data .
|
|
ArgumentError — Texture Format Mismatch: if the texture format is Context3DTextureFormat.COMPRESSED or
Context3DTextureFormat.COMPRESSED_ALPHA and the code is executing on a mobile platform where runtime texture compression is not supported.

error | event |
flash.events.ErrorEvent
flash.events.ErrorEvent.ERROR
Language version: | ActionScript 3.0 |
Runtime version: | AIR 24 |
Dispatched by the CubeTexture object when an asynchronous texture upload
operation fails in some way. The failure code is provided in the
errorID
field of the error object.
Defines the value of the type
property of an error
event object.
This event has the following properties:
Property | Value |
---|---|
bubbles | false |
cancelable | false ; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
target | The object experiencing a network operation failure. |
text | Text to be displayed as an error message. |
textureReady | event |
flash.events.Event
flash.events.Event.TEXTURE_READY
Language version: | ActionScript 3.0 |
Runtime version: | AIR 24 |
Dispatched by the CubeTexture object when an asynchronous texture upload operation has completed successfully, and the texture can then be used.
The Event.TEXTURE_READY
constant defines the value of the type
property of a textureReady
event object.
This event is dispatched by Texture, RectangleTexture and CubeTexture objects to signal the completion of an asynchronous upload. Request an
asynchronous upload by using the uploadCompressedTextureFromByteArray()
method with a true
value for the async
argument, or using a method such as uploadFromBitmapDataAsync
or
uploadFromByteArrayAsync
.
This event neither bubbles nor is cancelable.
This event has the following properties:
Property | Value |
---|---|
bubbles | false |
cancelable | false ; there is no default behavior to cancel. |
target | The texture object that dispatched this event. |
