View Full Version : How do I texture map a Triangle Strip?

Word on the street is: one triangle strip
is faster than a bunch of triangles. This
makes sense, since triangle strips need
fewer vertices. So, I want to use triangle

But, how do I assign texture coordinates?

Each vertex in a triangle strip can be
part of three different triangles, and
(I'm thinking) needs three different
texture coordinates. Is there some way
to deal with this?

Any help greatly appreciated!

Because all the triangles in a triangle strip are linked, you only need one texture coordinate per vertex, just the same as doing individual triangles.

Ah hah! (Light going off in my head! http://www.opengl.org/discussion_boards/ubb/smile.gif )

A single texture will map across all the
triangles in the strip! Now it makes
sense. http://www.opengl.org/discussion_boards/ubb/biggrin.gif

Thanks, J!
