Re: Maximum number of blocks

[Kevin Thomas <kjt@sgi.com>]

Dean,

Yes, you can have as many blocks in your model as memory will
allow.  Each geometry block requires about 200 bytes.
Other block types are generally larger, but I don't think that
there are any over 1000 bytes.

You can increase the number of blocks that the View Blocks
dialog will display in the block list, if you wish, by setting
the Lc.maximumBlockListSize resource.  There are several ways
to make this happen, one of which is to specify the new value
on the command line,

  lc -xrm 'Lc.maximumBlockListSize: 20000'

for example, to set the limit to 20000.  The problem with setting this
value too high is that the display algorithm which the OSF/Motif
"list widget" uses seems to increase in run time quite rapidly as the
number of items gets large.  LC uses this list widget to display the
list of block names.

Some of the other algorithms used in LC can get expensive in run time
if the number of blocks grows large.  But there is no fixed limit.
