    You simply give each vertex a set of texture coordinates and then that will be used to map the texture onto your object.

    All right, I thought this might happen. What API are you using? Then maybe I can help you a bit more.

    no, what are you using to render the texture mapped quad? Direct3D/DirectDraw, OpenGL, software rasterizer?

    Go take a look at www.gametutorials.com under there OpenGL section. They have a tutorial for texture mapping a quad, and then it shouldn't be hard for you to apply the concept to 3D models.
