#### INST Examples

Here are some examples of `INST` files

    INST
         unit < xyz.vect
         transform {
            1 0 0 0
            0 1 0 0
            0 0 1 0
            1 3 0 1
         }

    { appearance { +edge  material { edgecolor 1 1 0 } }
        INST geom < mysurface.quad }

    {INST transform {: T} geom {<dodec.off}}

    { INST
         transforms
             { LIST
         	{ < some-matrices.prj }
         	{ < others.prj }
         	{ TLIST <still more of them> }

             }
         geom
             { # stuff replicated by all the above matrices
         	...
             }
    }

This one resembles the `origin` example in the section above, but makes the X and Y edges be 1/4 the size of the window (1/4, not 1/2, since the range of ndc X and Y coordinates is -1 to +1).

    { INST
      location ndc
      geom { < xyz.vect }
      transform { .5 0 0 0  0 .5 0 0  0 0 -.009 0   0 0 -.99 1 }
    }
