Make Tileable Routine for IRender
We have completed our new make Tileable routine.
Here is an example of the new "Make Tileable" feature in IRender, RpTools, and NprTools:
- You place the high-quality, but non tiled, material in SketchUp.
- You right click on a face with the material, and select "Make Tileable"
- We load a wizard which shows a tiled example of the material on the SketchUp face, and what it will look like using one of two tiling methods.
Original Texture and two Tiling mathods
- The Current Tiled Preview shows what the "non-tileable" texture looks like when tiled.
- The lower left one uses a special tiling algorithm. The image is modified to make it tileable by folding itself back in on itself. The texture itself is modified, but if it did not need to be precisely the same, this makes a nice tileable texture.. The sample show a 2 X 2 pattern so you can see the tiling in action.
- The lower right frame shows a new texture made by "BookMatching" the original image.This is done by mirroring the texture in the X and Y direction. For many textures, it works great, but for some it creates a pattern which is objectionable. The advantage of BookMatched is that the original texture remains intact, and is simply mirrored to make it tileable.
Here are renderings of a wood desk with the three tiling patterns:

That's a very good idea I already used with gimp for example.
But I used bookmatched algorythm in both directions, vertical and horizontal which gives good results to map it on large surfaces.
it Could be interesting to propose it in your wizard.

I believe our bookmark does go both ways.
We are considering adding a checkbox for "Both" to both make it tileable, and book mark it. Has anyone tried this?
But our big problem is wood or fabric samples which have lighting which increases across the sample. Even with the radius-ed algorithm. Has anyone found or used a filter which tries to balance overall intensity over a pattern?
See this image, where the radiused algorithm - when then tiled 2 x 2 leaves a line between patterns based on the intensity changes in the original image.

Of course I had the same problem. I tried to correct such problem in gimp making a mask based on illumination balance, and use divide, multiply, etc...I don't really remember. Anyway, the problem quickly gives a headache.
But it exists a solution of course because I asked a photographer to do it and he got the result which allows me to make the tile above.
Unfortunately, I don't know how he did.

when I right click in sketchup with IRendernxt I do not get "Make Tileable" option with latest download - only Edit, Show Attributes, Set object properties, and Render slection under IRender Nxt, or is it show where else.?

You have to right click on a material which already has a texture, then click Edit Material, then go to the Texture Tab, then click Make Tileable.
We plan to make this a little easier.

Came across this "color variation across the image", don't have full PS so no colour match, just elemenst but high pass seemed to work, then just lighting etc to get colours back etc.
