5.20. Fdp (element)

5.20.1. Attributes

5.20.2. Description

This element defines a table of keypoints in a subdivision, a mesh made of a set of faces with normals and texture coordinates. Each keypoint is bound to a vertex (this relationship is not used in vertex displacement computation) and to an external transformation node that is used to control directly the displacement of keypoints, and indirectly the displacement of vertices.

The integer value size of the size attribute defines the number of keypoints contained in the table of keypoints. This element expects size keypoint in its scope.

5.20.3. Expected children

The following elements must occur in fdp: as many keypoint as the value of the size attribute.

5.20.4. Example

The example below defines a fdp with two keypoints.

<fdp size="32">
  <keypoint index="1" vertex="2395" xlink:href="#2.1" />
  <keypoint index="2" vertex="414" xlink:href="#2.10" />
</fdp>
