Offer fast rendering for parts larger than: Check this

option to have ZPrint prompt you to use fast rendering

before drawing a part with more than the designated

number of facets entered in the Thousand Facets field.

You may override these setting for an individual build by

selecting Fast Rendering on the View menu.

NOTE: If you have a very fast computer video display, set

the facets threshold higher, or uncheck this option. If your

computer is slow to draw and refresh the screen, set the

facets threshold lower. The recommended threshold is

100,000 facets.

Automatically build display list for parts smaller than:

Check this option to view the build list for parts that are

smaller that the designated amount of facets entered in

the Thousand Facets field.

Building the display list pre-compiles facets in OpenGL.

This makes rotating, zooming, and panning in 3D

smoother. This operation varies in processing time

depending on the file size. If the part will not be viewed in

3D, it is not necessary to build the display list. To prevent

the software from automatically building the display list,

set the threshold to a higher value. You may manually

build the display list after you have opened or imported a

file by choosing the Make Display List icon on the Tool-

bar.

In fast rendering mode display every: Enter a value in

this field to accelerate displaying large files in ZPrint dur-

ing fast rendering. The default value is to display every

fifth facet. In cases where a file contains a large amount

of facets, even fast rendering can be slow. To decrease

the time it takes to render, change the facet value to a

higher number in order to decrease the number of facets

rendered. For example, if the facet value was 500, the

software would render every 500th facet.

Always use full rendering in print status window: In

most cases, full rendering can be used in the Printing dia-

log during printing. For large files, displaying the status of

a print job is delayed due to rendering updates. In these

situations, uncheck this option and use full rendering.

When this option is unchecked, the Printing dialog uses

the same rendering mode as the main window.
