Constructors
constructor
Instantiates a new ThinRenderTargetTexture. Tiny helper class to wrap a RenderTargetWrapper in a texture. This can be used as an internal texture wrapper in ThinEngine to benefit from the cache and to hold on the associated RTT
Parameters
engine: ThinEngine
Define the internalTexture to wrap
size: TextureSize
Define the size of the RTT to create
options: RenderTargetCreationOptions
Define rendertarget options
Returns ThinRenderTargetTexture
Properties
anisotropic
With compliant hardware and browser (supporting anisotropic filtering) this defines the level of anisotropic filtering in the texture. The higher the better but the slower. This defaults to 4 as it seems to be the best tradeoff.
delay
Define the current state of the loading sequence when in delayed load mode.

Accessors
coordinates
How a texture is mapped. Unused in thin texture mode.
Returns number
is2DArray
Define if the texture is a 2d array texture (webgl 2) or if false a 2d texture.
Returns boolean
Define if the texture is a 2d array texture (webgl 2) or if false a 2d texture.
Parameters
value: boolean
Returns void
is3D
Define if the texture is a 3d texture (webgl 2) or if false a 2d texture.
Returns boolean
Define if the texture is a 3d texture (webgl 2) or if false a 2d texture.
Parameters
value: boolean
Returns void
is
Define if the texture is a cube texture or if false a 2d texture.
Returns boolean
Define if the texture is a cube texture or if false a 2d texture.
Parameters
value: boolean
Returns void
render
Gets the render target wrapper associated with this render target
Returns Nullable<RenderTargetWrapper>
sampling
Get the current sampling mode associated with the texture.
Returns number

Methods
delay
Triggers the load sequence in delayed load mode.
Returns void
disposeSearch playground for dispose
Dispose the texture and release its associated resources.
Parameters
Optional disposeOnlyFramebuffers: boolean
Returns void
get
Get the base size of the texture. It can be different from the size if the texture has been resized for POT for instance
Returns ISize
the base size
get
Get the class name of the texture.
Returns string
"ThinRenderTargetTexture"
get
Get the underlying lower level texture from Babylon.
Returns Nullable<InternalTexture>
the internal texture
get
Get the size of the texture.
Returns ISize
the texture size.
is
Get if the texture is ready to be used (downloaded, converted, mip mapped...).
Returns boolean
true if fully ready
release
Release and destroy the underlying lower level texture aka internalTexture.
Returns void
resizeSearch playground for resize
Resize the texture to a new desired size. Be careful as it will recreate all the data in the new texture.
Parameters
size: TextureSize
Define the new size. It can be:
- a number for squared texture,
- an object containing { width: number, height: number }
Returns void
update
Update the sampling mode of the texture. Default is Trilinear mode.
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
This is a tiny helper class to wrap a RenderTargetWrapper in a texture usable as the input of an effect.
