Model Resource 147
A model also contains modifiers that control how the model is rendered or how its animation
behaves. Modifiers are attached to a model by using the
addModifier() method. After a modifier
has been attached to a model, its properties can be manipulated with script.
The following modifiers are available to a model:
For more information about the methods, properties, and events available to the modifiers, see
the Using Director topics in the Director Help Panel.
Model Resource
Represents an element of 3D geometry that is used to draw 3D models.
A model makes use of a model resource and occupies a specific position and orientation with a
3D world. A model also defines the appearance of the model resource, such as what textures and
shaders are used.
For more information about the relationship between models and model resources, and about
using models and model resources, see the Using Director topics in the Director Help Panel.
You can create a reference to a model resource by using the
modelResource property of the 3D
Member object. The modelResource property gets the model resource at a specified index
position in the list of model resources. In Lingo, you use the
modelResource property directly
from the 3D Member object to create a reference. In JavaScript syntax, you must use the
getPropRef() method to create a reference.
The following example creates a reference to the second model resource of the 3D cast member
wheels and assigns it to the variable myModelResource.
-- Lingo syntax
myModelResource = member("wheels").modelResource[2]
// JavaScript syntax
var myModelResource = member("wheels").getPropRef("modelResource", 2);
Modifier Description
Bones player Modifies a model’s geometry over time.
Collision Allows a model to be notified of and respond to collisions.
Inker Adds silhouette, crease, and boundary edges to an existing model.
Keyframe player Modifies a model’s
transform properties over time.
Level of detail (LOD) Provides per-model control over the number of polygons used to
render a model, based on the model’s distance from a camera.
The LOD modifier is also available to model resources.
Mesh deform Alters an existing model resource’s geometry at runtime.
Subdivision surfaces (SDS) Causes the model to be rendered with additional geometric detail in the
area of the model that the camera is currently looking at.
Toon Changes a model’s rendering to imitate a cartoon drawing style.
