what is the difference between segmentation and mosaics

[Dragonkort]

i hope everyone had a wounderful christmas!  My youngest daughter got me a fantasy and medieval mosaics wood pattern book.  i also have a segmented wood pattern book. Now  after having read the instructions in the mosaics pattern book they seem to be done the same way....i'll have to dig out my segmentein pattern book and reread it but from what i remember after doing the segmentaions they seem to be done and finished the same way. is there a difference im not seeing or that im missing?  id like to know before i get a pattern out and start making it as i want to be sure im doing right....going to reread the mosic instructions again to try to find what iv missed

 Thanks for the information and help in advance

Segmentation is one pattern cut from one piece of wood, and then the wood is sanded to give it a 3 dimensional feel.

Mosaic is gluing small pieces of different colors in a way that presents a larger picture.

Thank you jim.  my mosic pattern book then has the pattern for both sesgmention and mosic.  the mosic pattern would be using different woods to make up the picture. using different colored woods, but also has the pattern cut from one piece of wood such as pine and then staining or painting each piece of wood before glueing everything together. in my segmention book the patterns tell me to cut the pattern in different pieces rounding over the edges a bit and then glueing the picture back together on a backer board. both books have instructions for using different colord woods and for cutting it out with just one type of wood such as pine and then staining or painting the pieces before glueing it back together on a baker board. i think thats why i got confused. I wish the pattern books would have explined each method and what they were called would have saved on some confusion.

Mosaic also leaves space between the parts that are glued

 

When you use different woods and glue them together touching each other, we call that intarsia.
