 | | BFC revisited —Gary Williams
|
| | | I'm looking for a model file that utilizes BFC-certified parts to test backface culling in the CAD application I'm developing. Unfortunately, as near as I can tell, only 13 part files have a BFC-related comment, and on top of that, they're not (...) (23 years ago, 16-Aug-01, to lugnet.cad.dev)

| | | | | There was never agreement on what the BFC standard should be. So there aren't very many parts that follow it in any way. I do have a set of primitives that are BFC-compliant. I didn't straighten out all the primitives, but I did a number of them. I (...) (23 years ago, 17-Aug-01, to lugnet.cad.dev)

| | | | | | | I forgot to mention: if anyone is interested in looking at the most-recent version of the BFC proposal, it's still at: (URL). The first screen of text is meta-comments about the status of the proposal. The actual proposal starts at the line "LDraw (...) (23 years ago, 17-Aug-01, to lugnet.cad.dev)

| | | | | | | | I have printed the bfcspec file for review. Hopefully I will get a response back to you. I have been using BFC in most all my new parts for the last six months or so. Please send me the BFC compliant primitives, so that I can be sure I am using them (...) (23 years ago, 17-Aug-01, to lugnet.cad.dev)

"l3p -check" doesn't complain, as "0 CERTIFY BFC CW" is a perfectly legal comment :-) I don't think l3p easily can be made to check this, "0 (...) (23 years ago, 19-Aug-01, to lugnet.cad.dev)
