Specifies whether or not the stencil and depth buffer are cleared between two rendering groups.
Parameters
renderingGroupId: number
The rendering group id corresponding to its index
autoClearDepthStencil: boolean
Automatically clears depth and stencil between groups if true.
Returns void
set
Overrides the default sort function applied in the rendering group to prepare the meshes. This allowed control for front to back rendering or reversely depending of the special needs.
Parameters
renderingGroupId: number
The rendering group id corresponding to its index
Optional opaqueSortCompareFn: Nullable<((a: SubMesh, b: SubMesh) => number)>
The opaque queue comparison function use to sort.

The alpha test queue comparison function use to sort.
Optional transparentSortCompareFn: Nullable<((a: SubMesh, b: SubMesh) => number)>
The transparent queue comparison function use to sort.
Returns void
to
Return a string representation of the texture.
Returns string
the texture as a string
update

Value Type Description 1 NEAREST_SAMPLINGMODE or NEAREST_NEAREST_MIPLINEAR Nearest is: mag = nearest, min = nearest, mip = linear 2 BILINEAR_SAMPLINGMODE or LINEAR_LINEAR_MIPNEAREST Bilinear is: mag = linear, min = linear, mip = nearest 3 TRILINEAR_SAMPLINGMODE or LINEAR_LINEAR_MIPLINEAR Trilinear is: mag = linear, min = linear, mip = linear 4 NEAREST_NEAREST_MIPNEAREST 5 NEAREST_LINEAR_MIPNEAREST 6 NEAREST_LINEAR_MIPLINEAR 7 NEAREST_LINEAR 8 NEAREST_NEAREST 9 LINEAR_NEAREST_MIPNEAREST 10 LINEAR_NEAREST_MIPLINEAR 11 LINEAR_LINEAR 12 LINEAR_NEAREST mag: magnification filter (close to the viewer) min: minification filter (far from the viewer) mip: filter used between mip map levels
Parameters
samplingMode: number
Define the new sampling mode of the texture
Returns void
updateURLSearch playground for updateURL

Optional onLoad: (() => void)
callback called when the texture is loaded (defaults to null)
Returns void
Optional forcedExtension: string
defines the extension to use to pick the right loader
Returns void
Static Create
Creates a texture from its base 64 representation.
Parameters
data: string
Define the base64 payload without the data: prefix
name: string
Define the name of the texture in the scene useful fo caching purpose for instance
scene: Scene
Define the scene the texture should belong to
Optional noMipmapOrOptions: boolean | ITextureCreationOptions
defines if the texture will require mip maps or not or set of all options to create the texture
Optional invertY: boolean
define if the texture needs to be inverted on the y axis during loading
Optional samplingMode: number

Optional creationFlags: number
specific flags to use when creating the texture (Constants.TEXTURE_CREATIONFLAG_STORAGE for storage textures, for eg)
Returns Texture
the created texture
Static Load

Parameters
name: string
Define the name of the texture in the scene useful fo caching purpose for instance
buffer: any
define the buffer to load the texture from in case the texture is loaded from a buffer representation
scene: Scene
Define the scene the texture should belong to
Optional deleteBuffer: boolean

Optional onLoad: Nullable<(() => void)>
define a callback triggered when the texture has been loaded
Optional onError: Nullable<((message?: string, exception?: any) => void)>
define a callback triggered when an error occurred during the loading session
Optional format: number
define the format of the texture we are trying to load (Engine.TEXTUREFORMAT_RGBA...)

the created texture
Static ParseSearch playground for Parse
Parse the JSON representation of a texture in order to recreate the texture in the given scene.
Parameters
parsedTexture: any
Define the JSON representation of the texture
scene: Scene
Define the scene the parsed texture should be instantiated in
rootUrl: string
Define the root url of the parsing sequence in the case of relative dependencies
Returns Nullable<BaseTexture>

Static When
Helper function to be called back once a list of texture contains only ready textures.
Parameters
textures: BaseTexture[]
Define the list of textures to wait for
callback: (() => void)
Define the callback triggered once the entire list will be ready
Returns void
Returns void
This Helps creating a texture that will be created from a camera in your scene. It is basically a dynamic texture that could be used to create special effects for instance. Actually, It is the base of lot of effects in the framework like post process, shadows, effect layers and rendering pipelines...
