3. Customizing the 3D Display
The rendered display has a few options that provide heads-up display objects and tools. These are items that are entirely independent of the model, so they are not saved in any file format. However, if the Save All Settings (see Chapter 7) option is selected, these display items will be retained between uses of quick3D. This chapter outlines the display options, which are contained under quick3D's Display menu.

Copy Image To Clipboard puts the current display on the Windows clipboard, so that you can paste it into other applications.

3.1 - Snapshots (menu items: Reset View, Take Scene Snapshot, Clear All Snapshots)

Selecting Reset View moves and rotates the model back to the way it was when the file was first loaded. This is helpful if you get lost in your scene, or can't seem to move the model where you want it and need to start over. There is also a way to "save" multiple orientations and display/scene settings groups to go back to later. These saved orientations are called "snapshots", and provide a way to undo your steps. Take a snapshot by selecting Take Scene Snapshot. A rendered window within the display will appear with an exact picture of the current display, including all current display settings. Figure 3.1 depicts an example.

Figure 3.1
Snapshot Example

Snapshot windows have a yellow toolbar as can be seen above. Clicking the circle reverts the current scene back to what is in the snapshot. The X button deletes the snapshot and closes its corresponding window. Clicking anywhere else on the snapshot window allows you to drag it around the quick3D display. If the snapshot windows seem too big or too small, there is an option that adjusts their size (see Chapter 7). You can delete and close all the snapshots together by selecting the Clear All Snapshots menu item.

3.2 - Mesh Display Settings (menu items: Solid, Wireframe, Hidden Lines Removed)

There are three modes for representing the mesh's geometry in the display. These are solid, wireframe, and hidden lines removed. Solid mode renders the mesh as a solid object, with no holes (unless they are inherent in the mesh's geometry). Wireframe mode displays the model as an outline of all of its edges. Hidden lines removed mode is similar to wireframe, except that any lines that would normally be behind others are removed so that you cannot see through the model. You can toggle between these modes using their corresponding menu items, or by clicking on the corresponding toolbar button (Figures 3.2, 3.3, and 3.4).

3.3 - Environment Display Settings (menu items: Lighting On, Texturing On, Culling On)

The other display settings that directly affect the model's appearance in the display are lighting, texturing, and culling. These affect the model in wireframe, hidden lines removed, and solid modes. Light casts light on the model as if it were coming from the same place the eye point is. It can help add to the appearance of depth, and also makes surfaces more shiny. If lighting doesn't seem to do anything except make the image dark, then most likely the light needs to be "inverted" (see Chapter 5.6). Texturing toggles whether or not any textures maps contained in the file are displayed. Culling toggles whether or not quick3D displays polygons that face backwards. In addition to their menu items, texturing and lighting have their own toolbar toggle buttons (Figures 3.5 and 3.6).

3.4 - Guide Items (menu items: Model's Axes, Pivot Point, Bounding Box)

There are three visual guides you can add to the display. They include a bounding box, a set of axes, and a yellow pivot point dot. The bounding box shows the smallest box that would fit around the model, and represents what you are "grabbing" onto when you use the mouse for model rotation. The axes show where the model's origin (0, 0, 0) is. Pivot point puts a yellow dot at the current pivot point. These guides have corresponding toolbar buttons for toggling them on and off (Figures 3.7, 3.8, and 3.9).
