Instantiates an HDRTexture from the following parameters.
The location of the HDR raw data (Panorama stored in RGBE format)
The scene the texture will be used in
The cubemap desired size (the more it increases the longer the generation will be)
Forces to not generate the mipmap if true
Specifies whether you want to extract the polynomial harmonics during the generation process
Specifies if the texture will be use in gamma or linear space (the PBR material requires those texture in linear space, but the standard material would require them in Gamma space)
Reserved flag for internal use.
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 cube texture It must define where the camera used to render the texture was set
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.
The texture coordinates mode. As this texture is stored in a cube format, please modify carefully.
Define the current state of the loading sequence when in delayed load mode.
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.
Is Z inverted in the texture (useful in a cube texture).
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
Gets or sets an object used to store user defined information.
Define the name of the texture.
An event triggered when the texture is disposed.
For internal use only. Please do not use.
Get the polynomial representation of the texture data. This is mainly use as a fast way to recover IBL Diffuse irradiance data.
Gets or sets the unique id of the texture
The texture URL.

Default anisotropic filtering level for the application. It is set to 4 as a good tradeoff between perf and quality.
Gets or sets the size of the bounding box associated with the cube texture When defined, the cubemap will switch to local mode

Get if the texture can rescale.
Define if the texture is having a usable alpha value (can be use for transparency or glossiness for instance).
Define if the texture is having a usable alpha value (can be use for transparency or glossiness for instance).
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).

Gets wether or not the texture is blocking during loading.
Sets wether or not the texture is blocking during loading.
Define if the texture is a cube texture or if false a 2d texture.
Define if the texture is a cube texture or if false a 2d texture.
Gets or sets whether or not the texture contains RGBD data.
Gets or sets whether or not the texture contains RGBD data.
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.
