The glFrustum man page (e.g. /usr/share/man/man3/glFrustum.3gl.gz)<br />
has a matrix expression for the function result, including this expression<br />
for the first element [0][0] of the matrix (actually the first column of the matrx):<br />
ccol { {{2 ~ "near_val"} over {"right" ~-~ "left"}} above 0 above 0 above 0 }<br />
<br />
In the terminal, this shows up as<br />
right?left<br />
----------<br />
(where ---------- is a solid underline)<br />
<br />
An online man page (e.g. <a href="http://www.opengl.org/sdk/docs/man2/xhtml/glFrustum.xml">http://www.opengl.org/sdk/docs/man2/xhtml/glFrustum.xml</a> [<a href="http://www.opengl.org/sdk/docs/man2/xhtml/glFrustum.xml" target="_blank">^</a>]) shows the values formatted correctly<br />
<br />
2 nearVal<br />
---------<br />
right - left<br />
<br />
where --------- is a solid line separating the numerator from the denominator)
