[X3D-Public] Can I create a colored shape without any light effects?

[Tomas Mikula]

Hello Sergey,

thank you, this is a better result than I had before, but is not
exactly what I wanted. The boundaries between boxes are still visible,
even if the color and transparency of adjacent boxes are the same.
Below is my minimal example. I use the FreeWRL browser.

Regards,
Tomas

       <Transform translation="-0.5 0 0">
               <Shape>
                       <Box size="1 1 1"/>
                       <Appearance>
                               <Material diffuseColor="0 0 0"
emissiveColor="1 0 0" transparency="0.5"/>
                       </Appearance>
               </Shape>
       </Transform>

                       <Appearance>
                               <Material diffuseColor="0 0 0"
emissiveColor="1 0 0" transparency="0.5"/>
                       </Appearance>
               </Shape>
       </Transform>
