.SH DESCRIPTION
The goal of \fInerverot\fP is to be interesting and compelling to
watch, yet induce a state of nervous edginess in the viewer. This manpage
-describes v1.2 of the program.
+describes v1.3 of the program.
.SH OPTIONS
.I nerverot
accepts the following options:
or the id number (decimal or hex) of a specific visual.
.TP 8
.B \-db
-.B \-no-db
+.B \-no\-db
Use double-buffering (or not, respectively). Double-buffering may make
things look better for larger line widths and/or larger numbers of
blots, but "better" may equate to yielding less of the desired edginess
The interframe delay, in microseconds. Defaults to 10000, resource
\fIdelay\fP.
.TP 8
+.B \-max\-iters \fIinteger\fP
+The maximum number of iterations (frames) before a new model is
+generated. The actual number of iterations per model is a random number
+between 1 and this value. Defaults to 1200, resource
+\fImaxIters\fP.
+.TP 8
.B \-count \fIinteger\fP
How many "blots" to draw at a time. This number may be rounded down to
fit the particularly chosen model, and has a fixed minimum per-model.
Defaults to 250, resource \fIcount\fP.
.TP 8
-.B \-line-width \fIinteger\fP
+.B \-line\-width \fIinteger\fP
The width of the lines to draw. 0 means an optimized pixel-thick line.
Defaults to 0, resource \fIlineWidth\fP.
.TP 8
-.B \-event-chance \fIfraction\fP
+.B \-event\-chance \fIfraction\fP
The chance, per iteration, for a life-altering event to occur (such as
picking a new rotation target), in the range 0..1. Defaults to 0.2,
resource \fIeventChance\fP.
.TP 8
-.B \-iter-amt \fIfraction\fP
+.B \-iter\-amt \fIfraction\fP
The fraction of movement towards a target (such as rotation angle or scale)
that happens per iteration, in the range 0..1. Defaults to 0.01,
-resource \fiterAmt\fP.
+resource \fIiterAmt\fP.
.TP 8
.B \-nervousness \fIfraction\fP
How nervous the drawing is, in the range 0..1. This is how jumpy the points
on each blot are. Defaults to 0.3, resource \fInervousness\fP.
.TP 8
-.B \-max-nerve-radius \fIfraction\fP
+.B \-max\-nerve\-radius \fIfraction\fP
The maximum radius of blot nervousness, as a fraction of the radius of the
blot, in the range 0..1. Defaults to 0.7, resource \fImaxNerveRadius\fP.
.TP 8
-.B \-min-radius \fIinteger\fP
+.B \-min\-radius \fIinteger\fP
The minimum radius for a blot, in the range 1..100. Defaults to 3,
resource \fIminRadius\fP.
.TP 8
-.B \-max-radius \fIinteger\fP
+.B \-max\-radius \fIinteger\fP
The maximum radius for a blot, in the range 1..100. Defaults to 25,
resource \fImaxRadius\fP.
.TP 8
-.B \-min-scale \fIfraction\fP
+.B \-min\-scale \fIfraction\fP
The minimum overall scale of drawing, as a fraction of
\fImin(windowHeight,windowWidth)\fP, in the range 0..10. Defaults to 0.6,
resource \fIminScale\fP.
.TP 8
-.B \-max-scale \fIfraction\fP
+.B \-max\-scale \fIfraction\fP
The maximum overall scale of drawing, as a fraction of
\fImin(windowHeight,windowWidth)\fP, in the range 0..10. Defaults to 1.75,
resource \fImaxScale\fP.
+.TP 8
+.B \-fps
+Display the current frame rate and CPU load.
