The use of textures is a basic technique for mimicking real world materials. The textures allow us to create very complex materials in an easy and quick way just by faking them with images pasted on the surface.
Imagine a wall of bricks. You could create the wall by modeling every brick, adding mortar, and layering on every small detail, but that would take forever. It would be easier to take a photo of a brick wall or paint a texture to create that look.
modo, and every other 3D software in the market, uses an axis-based projection system to stamp textures on your objects. You can imagine a texture moving along one of the three axes, approaching the object until finally meeting it. This technique is simpler than it seems. There are many types of projections present depending on the topology of the mesh. Now, we will learn which projection will be good for our model.
