This chapter describes how to build a 3D model in PhotoModeler. Before building the model, the user must create a project, and add photographs to it. See the sections Creating a New Project, and Importing and Using Photographs.
Building a 3D model is a three stage process:
• Mark the locations of features on each photograph.
• Possibly reference the points common to more than one photograph.
• Process the information you have entered.
This chapter is broken down into the following sections:
• The Objects That Make Up A Model - Describes the various types of 3D objects that are used to make up a 3D model in PhotoModeler, the properties of each object type and how each object has its 3D position computed.
• Marking - Describes the basics of marking points, edges, curves, cylinders, silhouettes etc. on photographs.
• Selection and Visibility - Describes the basics of selecting objects so you can later manipulate them.
• Referencing - Describes the basics of referencing marks between photographs so they can become 3D.
• Creating and Modifying Objects - Describes, in more detail, the marking, referencing, and editing of specific types of objects. Builds on the Marking, Referencing and Selection sections.
