MeshMaterialMetallicRoughness

A material determines how a MeshComponent is visualized. This particular material (based on MeshMaterial) uses the metallic/roughness lighting model to enable physically based lighting. The metallic and roughness properties can be used to model various realistic materials including metals and plastics.

In this image you can see how metallic and roughness property values influence the display of the material:

The metallicRoughnessTexture can be used to map specific metallic/roughness properties on different parts of the model.

Property Details

alphaCutoff Inherited Property alphaCutoff Number Inherited from MeshMaterial

Specifies how transparency on the object is handled. If alphaMode is set to either mask or auto this property specifies the cutoff value below which masking happens (that is, the coresponding part of the Mesh is rendered fully transparent).

Default Value:0.5

alphaMode Inherited Property alphaMode String Inherited from MeshMaterial

Specifies how transparency on the object is handled. See also alphaCutoff.

Type	Description
opaque	Alpha is ignored, and the object is rendered fully opaque.
blend	Alpha values are used for gradual transparency, blending between the object and its background.
mask	Alpha values are used for binary transparency, either displaying the object, or its background. See also alphaCutoff.
auto	The implementation mixes the `mask` and `blend` settings, masking below `alphaCutoff` and blending above it.

Possible Values:"auto"|"blend"|"opaque"|"mask"

Default Value:"auto"

color Inherited Property color Colorautocast Inherited from MeshMaterial Autocasts from Object|Number []|String

Specifies a single, uniform color for the mesh component. This can be autocast with a named string, hex string, array of rgb or rgba values, an object with r, g, b, and a properties, or a Color object.

Specifies a texture from which to get color information. The texture is accessed using the uv coordinate specified for each vertex in the Mesh.vertexAttributes.

colorTextureTransform Property colorTextureTransform MeshTextureTransform Since: ArcGIS Maps SDK for JavaScript 4.27 MeshMaterialMetallicRoughness since 4.15, colorTextureTransform added at 4.27.

A transformation of UV mesh coordinates used to sample the metallic roughness texture. Texture transformations can be used to optimize re-use of textures, for example by packing many images into a single texture "atlas" and using the texture transform offset and scale to sample a specific region within this larger texture.

Default Value:undefined

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

doubleSided Inherited Property doubleSided Boolean Inherited from MeshMaterial

Specifies whether both sides of each triangle are displayed, or only the front sides.

Default Value:true

emissiveColor Property emissiveColor Colorautocast Autocasts from Object|Number []|String

Specifies a single, uniform emissive color for the MeshComponent. The emissiveColor is added to the base color of the component. This can be autocast with a named string, hex string, array of rgb values, an object with r, g, b properties, or a Color object. Note that the alpha channel is ignored for emissive colors.

Specifies a texture from which to get emissive color information. The texture is accessed using the uv coordinate specified for each vertex in the mesh vertex attributes. The colors in the texture are added to the base color of the component. When using both an emissiveTexture and an emissiveColor their values are multiplied and then added to the base color of the component.

emissiveTextureTransform Property emissiveTextureTransform MeshTextureTransform Since: ArcGIS Maps SDK for JavaScript 4.27 MeshMaterialMetallicRoughness since 4.15, emissiveTextureTransform added at 4.27.

A transformation of UV mesh coordinates used to sample the emissive texture. Texture transformations can be used to optimize re-use of textures, for example by packing many images into a single texture "atlas" and using the texture transform offset and scale to sample a specific region within this larger texture.

Default Value:undefined

metallic Property metallic Number

Specifies how much the material behaves like a metal. Values must be in the range 0 (non metal material) to 1 (metal material). Physically accurate materials are usually either a metal (1) or a non-metal (0) and not something inbetween.

Default Value:1

Specifies a texture from which to get the combined metallic/roughness information. The metallic value should be stored in the blue channel, while the roughness value should be stored in the green channel. The red and alpha channels are ignored.

The texture is accessed using the uv coordinate specified for each vertex in the mesh vertex attributes.

Specifies a texture from which to get normal information. The texture is accessed using the uv coordinate specified for each vertex in the Mesh.vertexAttributes.

normalTextureTransform Inherited Property normalTextureTransform MeshTextureTransform Inherited from MeshMaterial Since: ArcGIS Maps SDK for JavaScript 4.27 MeshMaterial since 4.11, normalTextureTransform added at 4.27.

A transformation of UV mesh coordinates used to sample the normal texture. Texture transformations can be used to optimize re-use of textures, for example by packing many images into a single texture "atlas" and using the texture transform offset and scale to sample a specific region within this larger texture.

Default Value:undefined

Allows to specify a texture to get the occlusion information from. This can be used to simulate the effect of ambient light on the object. The texture is accessed using the uv coordinate specified for each vertex in the mesh vertex attributes. The occlusion value should be encoded in the red channel of the texture.

occlusionTextureTransform Property occlusionTextureTransform MeshTextureTransform Since: ArcGIS Maps SDK for JavaScript 4.27 MeshMaterialMetallicRoughness since 4.15, occlusionTextureTransform added at 4.27.

A transformation of UV mesh coordinates used to sample the occlusion texture. Texture transformations can be used to optimize re-use of textures, for example by packing many images into a single texture "atlas" and using the texture transform offset and scale to sample a specific region within this larger texture.

Default Value:undefined

roughness Property roughness Number

Indicates how rough the surface of the material is. Values must be in the range 0 (fully smooth surface) to 1 (fully diffuse surface).

Default Value:1

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,

    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

Parameter

groupKey *

optional

A group key.

Returns

Type	Description
Boolean	Returns `true` if a named group of handles exist.

Example

Removes a group of handles owned by the object.

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
