Texture Mapping...,
Hi Leif,
Welcome to the wonderful world of texture mapping. Taken into the world of 3D rendering shaders you can collectively lose your mind in wondering why "it did that"..., You have given me a clue to a problem I've had with texturing wood longerons with a wood texture. I can simply "bend" the map so that it maintains a parallel path with the "bent" longeron. It sounds simple but as usual there's more than a few caveats which will need "squirreling around with" prior to any declaration of success. In any regards I am impressed with the beautifully illustrated tutorial on performing the art of texture in Illustrator which is still the select pre-publishing software package for obtaining superior print grade output. Bien Cordialement, -Gil |

Improvements
Thanks Gil! I had a feeling you would be interested in this...
Improvements I think I'm getting the hang of this now. Here's a few improvements: The original texture has been divided up into three segments, to be used at random on the different sections of the leading edge cover. Like before, I'm using just one half of the original texture, the yellow portion, but recolored darker brown than the intended light brown paper to be printed on. The size is 50 percent (much larger pattern than before), and compressed slightly sideways to make the pattern even more "loose". Sections of the leading edge are more logical, like they would have cut it in the original (just my guess of course). Section outlines have been thinned. Finally, the patterns applied are slightly transparent (60 pct opacity), which should allow the basic paper color to shine through. - L. PS. You will find the texture used as a download in the first post of this thread. PPS. Texturing the leading edge this way is now done in just a few minutes. And no moving about of anything.

Thanks for the additional advice!

Of course if your aircraft's framing was spruce you are using the wrong texture map for color and for grain pattern. They would have used old growth, fine grain spruce. It has very tight growth rings with many straight grain lines per inch. So on a scale model they would be pretty much impossible to model in a texture map. It is a very pale colored wood. Do some image searches for the real thing before you decided on the final texture map to use.

KC, very valid point. Perhaps the fine-grained spruce is best reproduced by using very light yellow paper, and nothing else.
But I will probably not be able to keep myself away from textures, now that I stumbled upon the new (for me) method. Impressions, you know... If so, I'll go with a very light grey, and finely grained, pattern for longerons and cross-members. Is the birch ply OK, you think, or does it need to be toned down too? - L.

Leif, wonderful experiment/tutorial as usual.
If I can add my cent, when I was designing a canoa ( with your help for clipping the texture ), I tried to do a vectorized texture versus the raster one. Looking for hints and tutorials, I found this one (inkscape: create a woodgrain effect) that teaches the use of the calligraphy tool of Inkscape, but when i experimented it, the complexity of the woodgrain path made painfully slow to manage the design. So i abandoned the experiment. Do you have some suggestion how to generate the woodgrain pattern without need a monster elaboration power on our PC? Thnks in advance, Nando

Nando,
Me, too, shied away from the tutorials about how to create a vecture wood texture, and went afoot searching for free ones. Those that worked for me, I have attached in the first post of this thread. There is a version in .eps, too, if you can't use the Illustrator .ai ones. If you follow the hints in the posts above, there is nothing which makes my ten-year old computer protest. Hope it works out for you. - L.

Thanks Leif.
The .ai format works fine for me with Inkscape, I will use them in my wooden parts. Thanks for your quick and useful answer and my compliment for the design of those leading edges. Which plane are parts? Best, Nando

Ah, which plane could that be...
How about a little guessing game? All are invited. Leif
