There are also internal options
used only by sketch
and not
passed on to PSTricks
. These are summarized in the following
table.
Key | Possible values | Description
|
---|---|---|
cull
| true , false
| Turn culling of backfaces on and off respectively for this object.
The default value is true .
|
lay
| over , in , under
| Force this object to be under or
over all other objects in the depth sort
order created by the hidden surface algorithm. The default value
over guarantees that output due to the special will be
visible.
|
split
| true , false
| Turn splitting of sweep-generated body polygons
on and off respectively. See Sweeps. The default value true
causes “warped” polygons to be split into triangles, which avoids
mistakes by the hidden surface algorithm.

(x1,y1,z1)(x2,y2,z2)...
A sequence of one or more points makes a point list, a feature common to all drawables. Each of the point components is a scalar arithmetic expression. Any point may have the z-component omitted; it will default to z=0.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
