Clarification! .... snip (...) I am using additional points to specify the location of feet. Combined with the model location, I have 3 points for the hip and feet. [now the following paragraph should make more sense] (...) (18 years ago, 7-Apr-07, to lugnet.cad.ray, lugnet.cad)

(...) Arg. I thought this was going to be easy. I liked this part of the wikipedia article: "In practice, inverting a matrix is rarely required. Most of the time, one is really after the solution of a particular system of linear equations." Hm. I (...) (18 years ago, 7-Apr-07, to lugnet.cad.ray, lugnet.cad)

(...) Thanks, ROSCO. I took that code and modified it to use char instead of _TCHAR, and got timings of 720-750ms, compared to the 750-780ms I got with my original one. I then modified it to support CR and LF interchangeably, and got back to the (...) (18 years ago, 7-Apr-07, to lugnet.cad, FTX)

| | LDD Model of GG-1 Electric Locomotive - Advice Requested
|
|
I decided to model the very well known GG1 locomotive as a model available from LEGO Factory. I took some liberties with the design and color scheme in order to accomodate what can be done in LDD. Even so, I think the result is inherently (...) (18 years ago, 7-Apr-07, to lugnet.trains, lugnet.announce.moc, lugnet.cad.ldd, FTX) !

(...) I just realised something... do you want a general inverse or a specific inverse? Some inversions are simple eg. a pure rotation can be inverted by taking its transpose and reflections are their own inverses. Tim (18 years ago, 7-Apr-07, to lugnet.cad.ray, lugnet.cad)

(...) Quick question. I was in a hurry, and wanted to play it safe, so I call feof instead of checking to see if char1 == EOF. Any idea what gets returned for extended ASCII characters (>= 128)? Does the int contain positive numbers greater than (...) (18 years ago, 7-Apr-07, to lugnet.cad, FTX)
