Introduction

Canoma lets you quickly create 3D models from scanned or digital photographs. Canoma models can then be posted on Web sites, used in electronic catalogs, imported into traditional 3D modeling and animation software, or rendered as 2D image files.

The Canoma Workspace

This section leads you through the Canoma Workspace. The first thing you¡¯ll notice about Canoma is that it doesn¡¯t have traditional floating palettes and toolbars. All of Canoma¡¯s features are integrated into the Workspace, which takes over your entire screen. This helps keep everything uncluttered and easy to locate.

The Canoma Project Window
  • The Canoma Project Window is a square shaped window inside the Canoma application window. It¡¯s where you construct and view a Canoma model. The Project Window is used when you edit your models, manipulating object wireframes in Edit mode. It¡¯s your work area where you¡¯ll pin 3D objects to picture elements. The Project Window can be resized to suit your needs (grab it by the lower left corner) and moved to another part of the Canoma workspace (by the title bar.)
  • The Project Window is also where you view the 3D models you create. The view you see of your model in the Project Window is taken through a stationary ¡°camera.¡± You can reposition the Canoma camera in order to view your model from different angles or distances. When you view a 3D model, you¡¯re in a three dimensional space. That means you can even view your model from below or above.
  • Just outside the Project Window are some information displays and buttons. Along the top of the window is the title of your project and its size. To the top right of the window are three buttons that toggle display options on and off. To the bottom right of the window are buttons that let you change the color for program elements such as the background, selected objects, unselected objects, objects in the stress display, shadows, and object constraints.
Camera Controls

Use the Camera Controls to change the position and function of the viewing camera. The Edit and View buttons switch between:

  • Edit mode, where you can see the wireframe objects that make up your model
  • View mode, where you can see the untextured or textured 3D model
The Camera Crosses let you move the view of the camera specifically along X, Y, and Z axis. The Camera rackball lets you rotate the camera in any direction and around any axis. The Banking and Field of View control spheres tilt your Camera and act like a wide-angle lens control. Refer to "positioning the View of Your Model" on page 97 for more about positioning the camera around your model.
The Creation Tab

The Creation Tab contains the 3D objects, like boxes, rectangles, and even editable polyline contours. Select one of these 3D objects, position it, then ¡°pin¡± it to an element in your photograph. Once pinned into place, Canoma uses that placement information to create a 3D model, which can then be ¡°covered¡± with the pixels from your photographs.

The Toolbar

The Canoma Toolbar holds the tools you'll use to manipulate objects, view your work, and apply or edit textures. Click a button to activate that tool.
The Toolbar contains (from left to right):

  • Arrow (select, pin, or apply beads)
  • Glue (glue objects together)
  • Zoom and Pan (move into, away from, or around your scene)
  • Point Pen (add/delete polyline contour points)
  • Texture Brush (change textures at a pixel level)
  • Quick and Quality Textures (apply photograph pixels as textures for your 3D scene)

When a tool is selected, it is highlighted in the Toolbar. At the top of the Toolbar is a title that identifies which tool is active.
2D Image Palette

A thumbnail of your photograph is displayed on the 2D Image Palette. This is a thumbnail of the active image. The 2D Image Palette opens downward to reveal all the photographs in your project.

Texture Controls

The Texture Controls apply the pixels of your photograph to your 3D model. You can use Quick Texture (fast) or Quality Texture (slower, uses more memory, but looks better.) You can also use the Texture Resolution popup to choose a resolution setting for the textures you apply.

The Animation Tab

The Animation Tab holds the controls you need to use in order to quickly define key frames and set options to create an animation. Move the camera, take a "snapshot¡±, move the camera, take another snapshot, then Canoma completes the work by interpolating between the keyframes you¡¯ve snapped or ¡°filling in the gaps.¡±
