Reversing Vertex Order in Shader

I want to reverse the order that vertices are fed to a vertex shader. Any suggestions? I'm using ThreeJS, but the shader is custom.

Some background information: To solve the problem in the past, when I wasn't using a custom shader, I would just create the object geometry like this:

new THREE.CylinderGeometry( 16, 16, -32 )

instead of:

new THREE.CylinderGeometry( 16, 16, 32 )

and it would achieve what I need. The problem is that the geometry I'm using now is created in Blender and imported into the scene.

Why do you need to reverse the vertex order?

Perhaps you can just change the sidedness of your material to .side=THREE.BackSide or .side = THREE.DoubleSide if you are trying to solve backface culling problems?
