   applying textures across triangles
  This is a newbie Q, but here goes:I''m rendering a shape made of lots of triangles.  I have one texture to "fit over" this shape.  However, my rendering code draws everything a triangle at a time.  Now, common sense tells me (and common sense has been known to lie to me-- the bastard) that I should apply little bits of the texture to each triangle.  Now, I know that there''s got to be a better way.  What is it? or where should I look?Thanks. 
  That's the way it works.  The use of a single texture across an object composed of many polygons is called "skinning," and is one of the principles of 3D art creation.  Most often, you'll use your modelling tool to apply the texture by "unwrapping" the model and then laying out the vertices of the triangles where they belong.  Now, of course, there are procedural ways to go about texturing, by using various projections, but most commonly, you will give each vertex a pair of texture coordinates on a texture map manually.Later,ZE.
