Allows manipulation of a single vertex in a mesh.
Properties
pos |
A Vector describing the x,y,z position of the vertex. |
normal |
A Vector describing the x,y,z direction of the normal to the surface at this vertex. |
texture |
A Vector describing the texture coordinates at this vertex. |
Methods
normalize() |
Scales the normal of the vertex to be of unit length. |
Example
function onClick()
{
var verts=object.subgroups.Box.vertexGetArray(); // get all the vertices in the Box subgroup
verts[15].pos.x+=10; // move a vertex +10 along the X axis
object.subgroups.Box.vertexSetArray(verts); // save changes
var faces=object.subgroups.Box.faceGetArray(); // get all the faces in the Box subgroup
faces[0].materialIndex=1-faces[0].materialIndex; // swap material index of face between 1 and 0
object.subgroups.Box.faceSetArray(faces); // save changes
}
Remarks
Changes to the mesh are not written until the vertexSetArray function is called.
