package cesium
/**
* A 3D model based on glTF, the runtime asset format for WebGL, OpenGL ES, and OpenGL.
*
* Cesium includes support for geometry and materials, glTF animations, and glTF skinning.
* In addition, individual glTF nodes are pickable with [Scene.pick] and animatable
* with [Model.getNode]. glTF cameras and lights are not currently supported.
*
* An external glTF asset is created with [Model.fromGltf]. glTF JSON can also be
* created at runtime and passed to this constructor function. In either case, the
* [Model.readyPromise] is resolved when the model is ready to render, i.e.,
* when the external binary, image, and shader files are downloaded and the WebGL
* resources are created.
*
* Cesium supports glTF assets with the following extensions:
* - [KHR_binary_glTF (glTF 1.0)](https://github.com/KhronosGroup/glTF/blob/master/extensions/1.0/Khronos/KHR_binary_glTF/README.md)
* - [KHR_materials_common (glTF 1.0)](https://github.com/KhronosGroup/glTF/blob/master/extensions/1.0/Khronos/KHR_materials_common/README.md)
* - [WEB3D_quantized_attributes (glTF 1.0)](https://github.com/KhronosGroup/glTF/blob/master/extensions/1.0/Vendor/WEB3D_quantized_attributes/README.md)
* - [AGI_articulations](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Vendor/AGI_articulations/README.md)
* - [KHR_blend (draft)](https://github.com/KhronosGroup/glTF/pull/1302)
* - [KHR_draco_mesh_compression](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_draco_mesh_compression/README.md)
* - [KHR_materials_pbrSpecularGlossiness](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_materials_pbrSpecularGlossiness/README.md)
* - [KHR_materials_unlit](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_materials_unlit/README.md)
* - [KHR_techniques_webgl](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_techniques_webgl/README.md)
* - [KHR_texture_transform](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_texture_transform/README.md)
* - [KHR_texture_basisu](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_texture_basisu)
*
* Note: for models with compressed textures using the KHR_texture_basisu extension, we recommend power of 2 textures in both dimensions
* for maximum compatibility. This is because some samplers require power of 2 textures ([Using textures in WebGL](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API/Tutorial/Using_textures_in_WebGL))
* and KHR_texture_basisu requires multiple of 4 dimensions ([KHR_texture_basisu additional requirements](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_texture_basisu/README.md#additional-requirements)).
*
* For high-precision rendering, Cesium supports the [CESIUM_RTC](https://github.com/KhronosGroup/glTF/blob/master/extensions/1.0/Vendor/CESIUM_RTC/README.md) extension, which introduces the
* CESIUM_RTC_MODELVIEW parameter semantic that says the node is in WGS84 coordinates translated
* relative to a local origin.

* @property [backFaceCulling] Whether to cull back-facing geometry. When true, back face culling is determined by the material's doubleSided property; when false, back face culling is disabled. Back faces are not culled if [Model.color] is translucent or [Model.silhouetteSize] is greater than 0.0.
* Default value - `true`
* @property [showOutline] Whether to display the outline for models using the [CESIUM_primitive_outline](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Vendor/CESIUM_primitive_outline) extension. When true, outlines are displayed. When false, outlines are not displayed.
* Default value - `true`
