Python's built-in function type() returns the type of its argument. This makes it quite easy to check whether an object has a given type when compared to one of the constants in this module. CurveType : … do things only allowed for Curve objects ... Summary In this chapter, we have seen how to extend Blender with a full Python distribution and familiarized ourselves with the built-in editor. This enabled us to write scripts that, although simple, were fully integrated in Blenders scripting menu and help system.
Exit(), so our error() function may return. Creating a new Mesh object Once we have retrieved our lists of vertex co-ordinates and face indices from the mymesh module, we need some manner to create a new Mesh object in our scene and add MVert and MFace objects to this mesh. recalcNormals() The first line creates a new Mesh object with the name Bug. It will contain no vertices, edges, or faces and will not be embedded in a Blender object nor connected to any Scene yet. 001). The next two lines actually create geometry inside the mesh.
Verts. 001 verts edges MVert MVert MVert MVert MEdge MEdge MEdge MEdge MFace MFace MFace MFace faces This jumble of objects containing other objects may be confusing, so keep the previous diagram in mind and let's look at some example code to clarify things. We will define a cube. A cube consists of eight vertices connected by twelve edges. The eight vertices also define the six sides (or faces) of the cube.
