Creates a refraction texture used by refraction channel of the standard material. It is like a mirror but to see through a material.
Define the texture name
Define the size of the underlying texture
Define the scene the refraction belongs to
Define if we need to generate mips level for the refraction
Define the camera used to render the texture.
Define the list of animation attached to the texture.
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.
Gets or sets the center of the bounding box associated with the texture (when in cube mode) It must define where the camera used to render the texture is set
Gets or sets the size of the bounding box associated with the texture (when in cube mode) When defined, the cubemap will switch to local mode
Get if the texture can be rescaled or not.
Define the clear color of the Render Target if it should be different from the scene.
Define the UV chanel to use starting from 0 and defaulting to 0. This is part of the texture as textures usually maps to one uv set.
Override the default coordinates mode to projection for RTT as it is the most common case for rendered textures.
Override the render function of the texture with your own one.
Define the current state of the loading sequence when in delayed load mode.
Define how deep under the surface we should see.
In case the RTT has been created with a depth texture, get the associated depth texture. Otherwise, return null.
Define if the texture contains data in gamma space (most of the png/jpg aside bump). HDR texture are usually stored in linear space. This only impacts the PBR and Background materials
Defines if the alpha value should be determined via the rgb values. If true the luminance of the pixel might be used to find the corresponding alpha value.
Define if the texture is having a usable alpha value (can be use for transparency or glossiness for instance).
Define if the camera viewport should be respected while rendering the texture or if the render should be done to the entire texture.
List of inspectable custom properties (used by the Inspector)
Gets a boolean indicating if the texture needs to be inverted on the y axis during loading
Is Z inverted in the texture (useful in a cube texture).
In case a better definition than spherical harmonics is required for the diffuse part of the environment. You can set the irradiance texture to rely on a texture instead of the spherical approach. This texture need to have the same characteristics than its parent (Cube vs 2d, coordinates mode, Gamma/Linear, RGBD).
Define if the texture is a 3d texture (webgl 2) or if false a 2d texture.
Is the texture preventing material to render while loading. If false, a default texture will be used instead of the loading one during the preparation step.
Gets whether or not the texture contains RGBD data.
Define if the texture is a render target.
Intensity or strength of the texture. It is commonly used by materials to fine tune the intensity of the texture
With prefiltered texture, defined if the specular generation is based on a linear ramp. By default we are using a log2 of the linear roughness helping to keep a better resolution for average roughness values.
With prefiltered texture, defined the offset used during the prefiltering steps.
With prefiltered texture, defined the scale used during the prefiltering steps.
Gets or sets an object used to store user defined information.

Set a after unbind callback in the texture. This has been kept for backward compatibility and use of onAfterUnbindObservable is recommended.
An event triggered when the texture is unbind.
An event triggered when the texture is unbind.
Set a before render callback in the texture. This has been kept for backward compatibility and use of onBeforeRenderObservable is recommended.
An event triggered before rendering the texture
Set a clear callback in the texture. This has been kept for backward compatibility and use of onClearObservable is recommended.
An event triggered after the texture clear
Callback triggered when the texture has been disposed. Kept for back compatibility, you can use the onDisposeObservable instead.
An event triggered when the texture is disposed.
Observable triggered once the texture has been loaded.
An event triggered when the texture is resized.
Define the reflection plane we want to use. The refractionPlane is usually set to the constructed refractor. It is possible to directly set the refractionPlane by directly using a Plane(a, b, c, d) where a, b and c give the plane normal vector (a, b, c) and d is a scalar displacement from the refractionPlane to the origin. However in all but the very simplest of situations it is more straight forward to set it to the refractor as stated in the doc.
Define the refresh rate of the texture or the rendering frequency. Use 0 to render just once, 1 to render on every frame, 2 to render every two frames and so on...
Use this list to define the list of mesh you want to render.
Use this predicate to dynamically define the list of mesh you want to render. If set, the renderList property will be overwritten.
