After creating a mesh, you must set values for at least the vertexList and face[index].vertices properties of the new mesh, followed by a call to its build() command, in order to actually generate the geometry. Parameters meshName Required. Specifies the name of the new mesh model resource. numFaces Required. Specifies the desired total number of triangles you want in the mesh. numVertices Required. Specifies the total number of vertices used by all the (triangular) faces. A vertex may be shared by more than one face. numNormals Optional. Specifies the total number of normals. A normal may be shared by more than one face. The normal for a corner of a triangle defines which direction is outward, affecting how that corner is illuminated by lights. Enter 0 or omit this parameter if you are going to use the mesh's generateNormals() command to generate normals. numColors Optional. Specifies the total number of colors used by all the faces. A color may be shared by more than one face. You can specify a color for each corner of each face. Specify colors for smooth color gradation effects. Enter 0 or omit this parameter to get default white color per face corner. numTextureCoordinates Optional. Specifies the number of user-specified texture coordinates used by all the faces. Enter 0 or omit this parameter to get the default texture coordinates generated via a planar mapping. (See the explanation of #planar in the shader.textureWrapMode entry for more details). Specify texture coordinates when you need precise control over how textures are mapped onto the faces of the mesh. Example This example creates a model resource of the type #mesh, specifies its properties, and then creates a new model from the model resource. The process is outlined in the following line-by-line explanation of the example code: Line 1 creates a mesh containing 6 faces, composed of 5 unique vertices and 3 unique colors. The number of normals and the number of textureCoordinates are not set. The normals will be created by the generateNormals command. Line 2 defines the five unique vertices used by the faces of the mesh. Line 3 defines the three unique colors used by the faces of the mesh. Lines 4 through 9 assign which vertices to use as the corners of each face in the Pyramid. Note the clockwise ordering of the vertices. GenerateNormals() relies on a clockwise ordering. Lines 10 through 15 assign colors to the corners of each face. The colors will spread across the faces in gradients.
