Transparent ofSphere

Hey guys ,

I’m trying to make a transparent of sphere but change the material alpha is not working ? Somebody have some light ?

  
  
  
material.setDiffuseColor(ofFloatColor(255,255,255,100));  
  
  

Cheers

Try using ofSetColor(255,255,255,100) to get the alpha you want. If you want a transparent sphere.
also, ofFloatColor is from 0-1, not 0-255. Don’t forget to turn on ofEnableAlphaBlending()

There are many things that determine the overall color of a lit object in virtual 3d space. A little more about it here
