The UVs can be manipulated and can be edited after the projection. Fortunately for us, for every different mesh we can create itвЂ™s own projection. These projection types are great for the simpler objects according to their shape but for the complex objects like a face we canвЂ™t use planar projection or spherical projection.

A voxel grid is a series of 3D cubes that line up to form a bigger cube. This projection projects a vertical slice of the texture from the inside to the outside edge of the voxel. Same process applied to the Y-axis and the Z-axis. For example if you project a triplanar projection on a box, the texture is projected down from the positive X-axis towards the negative X-axis.

Triplanar mapping renders the texture 3 times in 3 different directions: X, Y and Z axes. Maya places texture on each plane and projects them onto the object. Projects the surface in the shape of the box. The key difference between ball and spherical projection is of the one pinch point to the mapping at the -z pole in the ball projection as opposed to the two pinch points at the +y and -y poles in spherical mapping. This projection is great for the objects that can be completely enclosed and visible within the cylinder like an arm, leg or pole.Д«all projection places the texture inside a ball and projects it onto the object. This projection is best for the objects like ball, planets or if you are creating an environment globe.Д¬ylindrical projection places the texture inside a cylinder and projects it onto the object. Spherical projection places the texture inside a sphere and projects it onto the object. If the model is complex, a planar projection overlap the UVs and look distorted. This projection type is best for the objects that are flat on the surface. Planer mapping places the texture on a planer surface and projects it onto the object. This is the default projection type used by maya. In the projection mapping we can chose from the seven different projection manipulators in maya. ItвЂ™s like unfolding and flattening of 3D object into 2D image. Once the model is complete, the next step is of creating a 2D representation of the 3D object. This requires the proper projection of the texture with the mesh because the poly UVs may not line up with the mesh and thatвЂ™s when вЂprojection mappingвЂ™ comes in handy. But for the complex 3D objects like a faces or body, chances of perfect texture layout is very low. Most of the 3d applications creates an automatic 3D layout when the mesh is originally created.

UVs act as marker points that control which points or pixels on the texture map correspond to which points or vertices on the mesh. UVs are essential because the provide the link between a surface mesh and how the 2D texture applied on the 3D surface. Just like the 3D space is coordinated in XYZ, the letters вЂњUвЂќ and вЂњVвЂќ represents the axes of the 2D texture because вЂњXвЂќ, вЂњYвЂќ and вЂњZвЂќ are already used to in the axes of the 3D object.

So what exactly is UV mapping and why chose UV? UV Mapping is the process of placing the texture directly on the surface and uses the surface coordinates called U and V for itвЂ™s positioning.
