Strata Foto 3D CX is an efficient, cost-effective system for modeling real world objects. Powered by Creative Dimension Software Ltd patented model generation and sophisticated texturing technology, Foto 3D CX allows a 3D model to be created quickly and inexpensively while requiring far less technical skill or expensive hardware than similar systems. Working seamlessly with the Strata family of 3D products, Foto 3D CX creates models that can be displayed and used in a variety of applications ranging from online product catalogs to 3D computer games. When used in conjunction with object modeling software like Strata Design 3D CX, Strata Foto 3D CX also allows virtual enhancements to existing products to be prototyped quickly and easily. Creating a new Foto 3D CX model involves following a simple workflow: Photograph Print and mount the specially designed calibration mat if you are using the standard approach. Place an object on a pedestal that is positioned on the mat. Set in front of a plain color background and under even lighting. Use a digital camera, preferably mounted on a tripod, to take pictures of the object. The object and mat are turned as a unit and about 20 photographs are taken from various angles. Upload the photos to a folder in your computer. Load the images into a new Foto 3D CX project. Place Markers (optional) If you didn't use a calibration mat, manually place markers in the image. Select pairs of images with overlapping features and place markers at feature points for both images. The markers are used to determine the relative position and orientation of the camera for each photo. Mask In each photo, the silhouette of the object is determined by a process called masking.
The markers are used to determine the relative position and orientation of the camera for each photo. Mask In each photo, the silhouette of the object is determined by a process called masking. Auto-masking wizards and tools help separate the object from its background. Model The silhouettes are combined to generate a 3D model automatically within a few minutes. The model can be simplified and made more compact by a process called decimation. The model can be smoothed using a tool that detects hard edges and rounds off the faces between those edges while still adhering to the shape required by the silhouettes. Texture The photos are then used to automatically paint the surface of the model with a U-V mapped baked-on texture. Several tools help to ensure the texture is seamless and allow it to be changed with an image editor. Display The final model can be saved and exported for display in a VRML-enabled web browser that will rotate the object and zoom in on the object's details. The model can also be imported into a 3D editing and rendering software such as Strata Design 3D CX for further enhancement and for it to be used in scenes and renders. Finally, the model can be imported into Strata Live 3D for interactive 3D display either with a sophisticated Java viewer or within PDF documents such as in a product catalog.

About this User Guide This User Guide is laid out to enhance your ability to learn the software quickly. Foto 3D CX provides some extremely powerful tools for modeling real-life objects, but to understand how to use them well requires a basic knowledge of the entire Foto 3D CX workflow. Accordingly, this manual is organized in three sections:
Part 1 - Getting Started Installing and getting acquainted with the software. Chapter 1 will help you get the software loaded and launched. Chapter 2 is a quick tutorial to take you through the steps of building a simple model using the automated wizards. Chapter 3 introduces the new Foto 3D Plug-in interface for Photoshop users.
Part 2 - The Tools and Basic Workflow Touring the workspace, explanation of each tool and control, and how to use the Wizards that initiate each of the three stages of the Workflow. Chapter 4 gives you a tour of the Workspace, followed by a detailed listing and explanation of the menu items and buttons found on the screen. Chapter 5 helps you setup to photograph your own objects, explaining what the software requires to be able to successfully create a model from your photos. Chapter 6 takes you through the three stages of the workflow used for every model - masking images, generating the wireframe and texturing the surface.
Part 3 - Advanced Techniques Advanced tools and techniques for optimizing the model at
Chapter 6 takes you through the three stages of the workflow used for every model - masking images, generating the wireframe and texturing the surface.
Part 3 - Advanced Techniques Advanced tools and techniques for optimizing the model at each stage of the workflow. Chapter 7 introduces the Edit Markers palette for creating 3d models from photographs without a calibration mat. Chapter 8 provides recommendations for photographers about how to optimize a photo studio setup for use with Foto 3D CX. Chapter 9 describes the advanced tools for editing and improving the masks and the wireframe model produced by that Wizard. Chapter 10 describes the advanced tools for editing and improving the surface texture produced by that Wizard. Chapter 11 has suggestions for display, use and rendering of the finished Foto 3D CX model.
Appendix The Appendix includes a Glossary, upgrade options, steps for calibrating a lens, and the license agreement.
