 | | New Ldraw parts authors tool: Projector
|
| (URL) This new tool allows easy creation of non-flat patterned LDraw parts. Create a flat pattern and stamp it on a 3D former. Program, documentation, source code are available (URL) here>. To show the usefulness of this tool, I created the four (...) (17 years ago, 7-May-08, to lugnet.announce, lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX) !

| Wow! That is very cool! I'm going to have to find a curved piece in one of my models that needs a pattern and try it out. Thanks! Scott (17 years ago, 7-May-08, to lugnet.cad.dev, FTX)

| Very nice. I don't author parts, so I won't be trying it out. However, I looked at your tutorial, and I have two suggestions: Add "Un-Project", where it takes a projected shape and flattens it automatically on an axis specified by the user (X, Y, or (...)

| (...) Wow. Awesome. I've been meaning to write something like this for ages so I'm very happy. Would it work on minifig faces too? Tim (17 years ago, 7-May-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)

| (...) It should. One interesting aspect is that while photo/scan distorts the pattern, flattening the shape to put it in quad2dat does the same distortion so they compensate each other! Philo (17 years ago, 8-May-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)

| (...) I was curious if it was a direct projection or an area preserving one. A nice variant might be to write an area preserving variant although that would get quite complex. Tim (17 years ago, 8-May-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)

| (...) It's a direct parallel projection. I think it's the best since the photo (with a long focal lens) or a scan has the same projection. Philo (17 years ago, 8-May-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)

| (...) For unproject MLCad does the job. Symply select everything and set the appropriate matrix row at 0. This is perfect for triangle, quads... If you have primitives you have to later automatically fix the "all zero matrix row" using LDDP. The (...) (17 years ago, 8-May-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)

| Reading your tutorial made me wonder whether scans of the orignal parts could be vectorized using Inkscape (Inkscape includes an automatic raster-to-vector converter). The resultant SVG (Scalable Vector Graphics) file could then maybe be converted (...) (16 years ago, 10-Jun-08, to lugnet.cad.dev, lugnet.vikings, lugnet.castle, FTX)

| (...) Hi Mike, Yes, I considered this possibility in the beginning, but I was not convinced by the vectorization process. One key issue is that silk-screened parts are far from perfect (misprints, color registration problems...). I found that (...)
