Extruded Shapes with distinguishable faces


Recommended Posts

Hi MC!

"distinguishable faces"?  Not real sure what you mean.

Like... mesh.convertToFlatShadedMesh()?


That adds extra vertices and has some other problems.

Some folks use a clone, and then set a wireframe material on the clone.


And BOTH can be done, as wanted.  Hope this helps.

Oh, JohnK beat me to the answer.  :)  Hi John, happy holidays.

Cool!  Lighting is interesting, when using flat-shading.  Flat-shade a medium-subdivided sphere, and perhaps color it.  With the right combination of directional lights (perhaps 2-4), each slightly different .intensity, you can make each 2-face "facet" on the sphere... be a different color from any other facet. 

I'd start with 2 directional lights.  Although positioning a directionalLight is often not necessary, let's do it anyway.

When not using a ground-plane, set first directional light at position oh... -20, -20, -20.  Then call its handy light.setDirectionToTarget(sphere.position).  Light.intensity = 0.8, perhaps.

Set second directional light at position 20, 20, 20, and call light.setDirectionToTarget(sphere.position).  Light.intensity = 1.2;

How's the many-faceted sphere, look?  Is every square... a different color from any other?  Stupid stuff like this... fascinates simple minds like mine.  :)

Perhaps try it with spotLights.  A command like... spotlight.setDirectionToTarget(orbitingAroundMySceneMesh.position) is pretty fun... when put inside the render loop (using registerBeforeRender).  It reminds me of old wartime ground-based search lights... following warplanes... tracking them across the sky.  See our playground lighting demo... for sin/cos orbit-a-mesh techniques.

Sorry, Wingnut rattling-on, aimlessly.  :)  Hey, I got the snowblowing done... here at my slummy 4-plex!  Hurray.  It's only 0 degrees out there, and breezy.  brrrr.  I dressed in "full spacesuit".  Not much snow, though, so street-plow snowbanks were small and fast.  My snowblower was a bit bitchy... but performed well (I had to coax it into forward gear, after a reversing, sometimes.  Stuff was stiff). 

DONE!  Coffee and doughnuts time!  Party!
