How to map textures onto Polygons

There are three ways to project and place a texture onto a model:

Planar Mapping projects a texture map onto an object using the projection plane of the texture map. This type of projection is best suited to flat objects.

Choose Polygons > Texture > Planar Mapping - to open the options window.

Cylindrical and Spherical mapping bends a texture map into a cylindrical shape over a cylindrical-shaped object and a spherical shape over a spherical-shaped object.



1.Press F11, or press the right mouse button and select Face from the marking menu, then marquee-select the entire object or click to select the faces you want to map.
2.Click the beside Edit Polygons > Texture > Cylindrical or Spherical Mapping to open the options window.



Note:

1.Do not select As projection or As stencil. Interactive placement is for NURBS, not polygonal geometry.

2.If there are no UVs on the object (see UVs and polygonal texture mapping for information about UVs), the texture will not display when in shaded Hardware Texturing mode. The texture can only be seen in the 3D view after you select a mapping technique, such as Cylindrical Mapping, to place the texture. These mapping methods create UVs if there are none on the object.

    i think it's possible to assign snap points to the texture so that when it is mapped it will be more realistic (eg setting the brow and nose ridge as snap points for a face-map results in a more realistic mapping of the texture right). Also, for fractal generation of meshes for terrain, check out Vue d'Esprit 5 by Eon Software. Damn good fractal generator and a super fast raytracer. Very impressive. You can port the mesh over to Maya to render if you want authenticity.

    Stupid, pointless crap in all these "posts". Get a life.
