ADOBE DIRECTOR 11.0 333 User Guide Mesh generator properties The mesh generator is the most complex model resource. It allows experienced 3D programmers to create complicated geometries at runtime. The mesh generator primitive's type property is #mesh and is created by the member's newMesh() method. The parameters included with that method describe how large the mesh will be. You can use the mesh deform modifier to manipulate vertex positions at runtime for #mesh or any other type of model resource. You can also use the #mesh primitive to change mesh properties directly, but this is usually not practical, because the mesh must be rebuilt mathematically after each modification. Use the following properties to work with mesh primitives: Property vertexList Access Get and set normalList Get and set texture Coordinate List Get and set texcoordlist colorList Get and set face.count Get face[index].v Get and set ertices face[index]. Get and set normals Description Value Range Vector values for each vertex in the mesh. Several Set the value to the faces may share a single vertex. number of vectors speci- fied in your newMesh call. Vector values for each normal in the mesh. Several faces may share a single normal. A normalized vector is one in which all components are of unit length. No default. Instead, set the value to the number of vectors specified in your newMesh call. You can use the generateNormals() method instead of specifying normals yourself. In that case, set 0 as the number of normals in your newMesh() call. The normals are calculated based on a clockwise vertex winding. That is to say, if you imagine the vertices being wound down a spindle, they would be wound from left to right, in a clockwise manner. A list of sublists identifying locations in an image used for texture-mapping a triangle. Each sublist contains two values between 0.0 and 1.0 that define a location and can be arbitrarily scaled to any texture size. No default. Instead, set the value to the number of two-element sublists specified in your newMesh call. List identifying every color in the mesh. Any color can be shared by several faces. Alternatively, specify texture coordinates for the mesh faces and apply a shader to models using this model resource. No default. Instead, set the value to the number of colors specified in your newMesh call. Number of triangles in the mesh. The number of faces specified in your newMesh call. List indicating which vertices to use for faces at designated index points. Set the value to a list of three integers specifying the indexes of the vertices in the vertexList that define this face. List indicating which normals to use for faces at designated index points. Set the value to a list of three integers specifying the indexes of the normals in the normalList that each point of the triangle should use. Don't set a value if you aren't defining your own normals.
