Module: models
Parent Module: xeogl

An STLModel is a Model that's loaded from an STL file.

Overview

  • An STL (“StereoLithography”) file is a triangular representation of a 3-dimensional surface geometry. The surface is tessellated logically into a series of triangles. Each facet is described by a perpendicular direction and three points representing the vertices (corners) of the triangle.
  • An STLModel is a container of Components that loads itself from an STL file.
  • It begins loading as soon as you set its src property to the location of a valid STL file.
  • You can set src to a new file path at any time, which causes the STLModel to clear itself and load components from the new file.
  • For binary STL, has the option to create a separate Mesh for each group of faces that share the same vertex colors. This allows us to treat STL models as parts assemblies.
  • Can be configured to automatically smooth STL models by converting their face-oriented normals to vertex-oriented.

STLModel inherits these capabilities from its Group base class:

  • Allows you to access and manipulate the Meshes within it.
  • Can be transformed as a unit within World-space.
  • Can be a child within a parent Group.
  • Provides its World-space axis-aligned and object-aligned boundaries.

Examples

Usage

Loading STL

Load an STL file by creating an STLModel:

var model = new xeogl.STLModel({
    id: "myModel",
    src: "models/stl/F1Concept.stl",

    // Some example loading options (see "Options" below)
    smoothNormals: true,
    smoothNormalsAngleThreshold: 45
});

An STLModel prefixes its own ID to those of its components. The ID is optional, but in this example we're providing our own custom ID.

The STLModel begins loading the STL file immediately.

To bind a callback to be notified when the file has loaded (which fires immediately if already loaded):

model.on("loaded", function() {
       // STLModel has loaded!
   });

You can also bind a callback to fire if loading fails:

model.on("error", function(msg) {
       // Error occurred
   });

To switch to a different STL file, you can dynamically update src:

model.src = "models/stl/F1Concept.stl"

That will apply whatever options were specified to the constructor.

Parsing STL

If we have STL data in memory, then we can parse it directly into an existing STLModel instance using the static parse method:

xeogl.STLModel.parse(model, stlData, {

   // Some example parsing options (see "Options" below)
    smoothNormals: true,
    smoothNormalsAngleThreshold: 45,
    combineGeometry: true,
    quantizeGeometry: true
});

That's asynchronous because STL is self-contained and does not need to load any external assets.

Options

The following options may be specified when loading or parsing STL:

Option Type Range Default Value Description
quantizeGeometry Boolean true When true, quantizes geometry to reduce memory and GPU bus usage (see Geometry).
combineGeometry Boolean true When true, internally combines geometry vertex buffers to improve rendering performance (see Geometry).
smoothNormals Boolean false When true, automatically converts face-oriented normals to vertex normals for a smooth appearance. See Smoothing Normals.
smoothNormalsAngleThreshold Number (degrees) [0..180] 20 See Smoothing Normals.
backfaces Boolean true When true, allows visible backfaces, wherever specified in the STL. When false, ignores backfaces.
ghosted Boolean false When true, ghosts all the model's Meshes (see Mesh and EmphasisMaterial).
outlined Boolean false When true, outlines all the model's Meshes (see Mesh and OutlineMaterial).
highlighted Boolean false When true, highlights all the model's Meshes (see Mesh and EmphasisMaterial).
selected Boolean false When true, renders all the model's Meshes as selected (see Mesh and EmphasisMaterial).
edges Boolean false When true, emphasizes the edges on all the model's Meshes (see Mesh and EdgeMaterial).
edgeThreshold Number [0..180] 2 When ghosting, this is the threshold angle between normals of adjacent triangles, below which their shared wireframe edge is not drawn.
splitMeshes Boolean true When true, creates a separate Mesh for each group of faces that share the same vertex colors. Only works with binary STL.

Smoothing Normals

As mentioned above, providing a smoothNormals flag to the constructor gives our STLModel a smooth appearance. Triangles in STL are disjoint, where each triangle has its own separate vertex positions, normals and (optionally) colors. This means that you can have gaps between triangles. Normals for each triangle are perpendicular to the triangle's surface, which gives the model a faceted appearance by default.

The smoothNormals flag causes the STLModel to recalculate its normals, so that each normal's direction is the average of the orientations of the triangles adjacent to its vertex. When smoothing, each vertex normal is set to the average of the orientations of all other triangles that have a vertex at the same position, excluding those triangles whose direction deviates from the direction of the vertice's triangle by a threshold given in smoothNormalsAngleThreshold. This makes smoothing robust for hard edges, which you can see on the cylindrical objects in one of the examples:

Note how the rim is smooth, yet the there is still a sharp edge adjacent to the flat portions.

Finding STLModels in Scenes

Our STLModel will now be registered by ID on its Scene, so we can now find it like this:

var scene = xeogl.getDefaultScene();
model = scene.models["myModel"];

That's assuming that we've created the STLModel in the default xeogl Scene, which we're doing in these examples.

We can also get all the STLModels in a Scene, using the Scene's types map:

var scene = xeogl.getDefaultScene();
var stlModels = scene.types["xeogl.STLModel"];

model = stlModels["myModel"];

Finding loaded Meshes

Once the STLModel has loaded, its Scene will contain various components that represent the elements of the STL file. We'll now access some of those components by ID, to query and update them programmatically.

Let's highlight an Object in our STLModel:

scene.omponents["myModel#1"].highlighted = true;

An STLModel also has an ID map of the components within it. Let's highlight another Object via the STLModel:

model.components["myModel#2"].highlighted = true;

An STLModel also has a map containing just the Objects:

model.objects["myModel#3"].highlighted = true;

TODO: ID format description

Transforming an STLModel

An STLModel lets us transform its Meshes as a group:

var model = new xeogl.STLModel({
    src: "models/stl/F1Concept.stl",
    position: [-35, 0, 0],
    rotation: [0, 45, 0],
    scale: [0.5, 0.5, 0.5]
});

model.position = [-20, 0, 0];

Getting the World-space boundary of an STLModel

Get the World-space axis-aligned boundary like this:

model.on("boundary", function() {
   var aabb = model.aabb; //  [xmin, ymin,zmin,xmax,ymax, zmax]
   //...
});

We can also subscribe to changes to that boundary, which will happen whenever

  • the STLModel's Transform is updated,
  • components are added or removed, or
  • the STLModel is reloaded from a different source,
  • the Geometries or Transform of its Meshes are updated.
model.on("boundary", function() {
   var aabb = model.aabb; // [xmin, ymin,zmin,xmax,ymax, zmax]
});

Clearing an STLModel

model.clear();

Destroying an STLModel

model.destroy();
