Since: ArcGIS Maps SDK for JavaScript 4.11

MeshTexture represents image data to be used for MeshMaterial or MeshMaterialMetallicRoughness. It is mapped to the mesh by its uv vertex attributes. MeshTexture instances can be used with the MeshComponent.material property and they can be set either as a MeshMaterial.colorTexture or as MeshMaterial.normalTexture. Images can be referred to either by url or directly by data ( HTMLImageElement, HTMLCanvasElement, HTMLVideoElement or ImageData).

const meshColorByUrl = new MeshTexture({
  url: "./image.png"
});

const mesh = Mesh.createBox(location, {
  material: {
    colorTexture: meshColorByUrl
  }
});

const meshColorByCanvas = new MeshTexture({
  data: canvasElement
});

const meshWithCanvasMaterial = Mesh.createBox(location, {
  material: {
    colorTexture: meshColorByCanvas
  }
});

// Support for autocasting within a mesh material constructor
const meshWithAutocastMaterial = Mesh.createSphere(location, {
  material: {
    colorTexture: {
      url: "./image.png"
    }
  }
});

// Mesh materials also support additional advanced autocasting types
// such as a Canvas element. In this case the canvas element will be
// available in the MeshTexture.data property.
const meshWithCanvasAutocastMaterial = Mesh.createSphere(location, {
  material: {
    colorTexture: canvasElement
  }
});

// When using a video as a texture, you need to create a Video element
// and pass it in the MeshTexture.data property.
const video = document.createElement("video");
video.src = "./my-video.mp4";
video.crossOrigin = "anonymous";
video.autoplay = true;
video.muted = true;
// The video needs to be added to the DOM and be located in
// the viewport in order for it to play
document.body.appendChild(video);
video.style.position = "absolute";
video.style.top = 0;
// Hide the video element
video.style.height = 0;
video.style.visibility = "hidden";

const meshWithVideoMaterial = Mesh.createPlane(location, {
 material: {
   colorTexture: { data: video }
 }
});

Constructors

MeshTexture

Constructor
new MeshTexture(properties)
Parameter
properties Object
optional

See the properties for a list of all the properties that may be passed into the constructor.

Property Overview

Any properties can be set, retrieved or listened to. See the Working with Properties topic.
Show inherited properties Hide inherited properties
Name Type Summary Class

A direct reference to the image or video data.

MeshTexture

The name of the class.

Accessor

Indicates whether the image data should be interpreted as being semi-transparent.

MeshTexture

The url to the image resource.

MeshTexture

Specifies how uv coordinates outside the [0, 1] range are handled.

MeshTexture

Property Details

A direct reference to the image or video data. The data can be an image element, canvas element, video element or ImageData. If the data is set to a video element, the element needs to be visible in the DOM. The data property is mutually exclusive with the url property, setting the data will clear the url (if there is one).

declaredClass

Inherited
Property
declaredClass Stringreadonly
Inherited from Accessor

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

transparent

Property
transparent Boolean

Indicates whether the image data should be interpreted as being semi-transparent. The default value is automatically derived when the data property contains a canvas element or an ImageData object. If instead a url to a .png file was provided, it is assumed that transparency is present. In all other cases it defaults to false.

Default Value:undefined

url

Property
url String

The url to the image resource. This can either be a remote url (absolute or relative) or a data url. Video resources can only be loaded using the data property. The url property is mutually exclusive with the data property, setting the url will clear the data (if there is one).

wrap

Property
wrap String |SeparableWrapModes

Specifies how uv coordinates outside the [0, 1] range are handled. One of "repeat", "clamp" or "mirror". Can also be specified separately for the two texture axes using an object:

{
  vertical: "clamp",
  horizontal: "repeat"
}

Possible Values:"clamp" |"repeat" |"mirror"

Default Value:"repeat"

Method Overview

Name Return Type Summary Class

Adds one or more handles which are to be tied to the lifecycle of the object.

Accessor

Creates a deep clone.

MeshTexture

Returns true if a named group of handles exist.

Accessor

Removes a group of handles owned by the object.

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.

clone

Method
clone(){MeshTexture}

Creates a deep clone.

Returns
Type Description
MeshTexture A deep clone of the object that invoked this method.

hasHandles

Inherited
Method
hasHandles(groupKey){Boolean}
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 4.25.

Returns true if a named group of handles exist.

Parameter
groupKey *
optional

A group key.

Returns
Type Description
Boolean Returns true if a named group of handles exist.
Example
// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles

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

Removes a group of handles owned by the object.

Parameter
groupKey *
optional

A group key or an array or collection of group keys to remove.

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

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");
