vertices

Usage

member(whichCastmember).modelResource(whichModelResource).\

face[faceIndex].vertices

Description

3D face property; when used with a model resource whose type is #mesh, this property allows you

to get or set which vertices from the resource’s

vertexList property to use for the mesh face

specified by

faceIndex.

This property is a linear list of three integers corresponding to the index positions of the three

vertices, as found in the mesh’s

vertexList property, that comprise the specified face.

The vertices must be specified in the list using counterclockwise winding in order to achieve an

outward pointing surface normal.

If you make changes to this property or use the

generateNormals() command, you will need to

call the

build() command in order to rebuild the mesh.

Example

This example displays the vertexList of the mesh model resource named SimpleSquare, then it

displays the

vertices property for the second face of that mesh:

put member("3D").modelResource("SimpleSquare").vertexList

-- [vector( 0.0000, 0.0000, 0.0000), vector( 0.0000, 5.0000, \

0.0000), vector( 5.0000, 0.0000, 0.0000), vector( 5.0000, \

5.0000, 0.0000)]

put member("3D").modelResource("SimpleSquare").face[1].vertices

-- [3, 4, 1]
