Our Personal Iris 4D/20G running SD3.1C exhibits problems when drawing polygons. The top pixel row and the right pixel column are not affected by the polygon drawing routines (bgn/endpolygon, v3...). This happens with all programs I've written as well as with the bounce or spin logo demos from SGI. You may use mag (which, however, has its own problems on a personal iris) and notice a slightly thicker black border. Since I'm reading back such drawings to postprocess them, those pixels introduce severe errors. Surprisingly, lrectread works just fine for reading back the pixels. The problem does not occur on a 4D/70GT (same OS level). Another problem: Can somebody explain me, why vi needs a huge amount of space in /tmp? e.g.: -rw-r--r-- 1 meyer 100000 Mar 17 10:54 foo % vi foo ... -rw------- 1 meyer 835584 Mar 17 11:00 /tmp/Ex05442 ^^^^^^!! The available space on our root filesystem of ~7MB therefore limits vi to edit files up to only ~900KB. But on a SUN3 (SunOS 4.0) or a VAX (4.3BSD): -rw------- 1 meyer 106408 Mar 17 11:03 /tmp/Ex02457 -- BTW: Could the person in charge of maintaining the info-iris mailing list resubscribe me.
