[comp.graphics] X Based Graphics Package

jml@jax.lgc.com (John Love) (07/10/90)

   I'm putting together a list of X based 2D and 3D graphics packages 
   for evaluation. 

   If you are familiar with a package that hits on some of the items I have
   listed below, please email me the product name / vendor (and a contact 
   if you have one). 

   If you sell a product that satisfies a subset of these criterion,
   please contact me (we will make a purchase decision by the end of July).

   (I realize that there are some good, "free" solutions, but we want a 
    product with support...this we are ready to pay for.)
