Curve Tessellation Determines the amount of detail for curves in your
drawing. A higher setting provides more detail but uses more tessellation lines
and more memory.
Number of Tessellations to Cache Configures your system according to
memory and performance requirements. The 3D cache always stores at least
one tessellation. When this option is set to 1, the tessellation for all viewports
is the same; some objects in the drawing may be regenerated as you zoom in
and out. Setting this option to 2 or more is useful when you have more than
one viewport with different views. Increasing the number requires more
memory.
General Options
Sets performance-related options that are not hardware dependent.
Discard Back Faces Discards back faces when drawing objects. You cannot
see the effect of discarding back faces on some objects, such as spheres, because
you cannot see the back face even when it is present. The effect of discarding
back faces is visible on objects such as those that don't have a top. Discarding
back faces enhances performance.
Transparency Quality Adjusts the transparency quality. At the Low setting,
a screen-door effect achieves transparency without sacrificing speed. At the
Medium setting, the default in software mode, blending improves image
quality. The High setting, the default in hardware mode, produces an image
free of visual artifacts at the cost of drawing speed. Materials must also be
turned on for transparency to be visible.
The General Options prompt is redisplayed.
Acceleration
Specifies whether to use software or hardware acceleration in 3D.
If you select Hardware, you can also specify whether geometry acceleration
are turned on or off.
Hardware Specifies hardware acceleration. The hardware graphics card
performs most of the drawing tasks in 3D to increase performance.
Driver Name. You can select a driver from a list of available
hardware-accelerated drivers found in the Drv directory. If you want to use
a hardware driver from another vendor, it must be supported by the Heidi
®
Graphics System.
