Flashlight

KB,
I don’t think you’re actually losing any color on the globe. Remember the first flashlight picture? It looked more dull when rendered with PovRay. I think this is a light_source positioning issue(not the spot light, but the other lights).

However, I really don’t see anything at all wrong with the latest picture. I agree with BHoltzman about Anti-Alaising, but I think what you are seeing in this pic is the effect of a spotlight hitting the globe with more intensity than point lights, causing the globe to appear a little darker, or more dull in other areas. You could always make your other lightsources brighter or move them closer to the globe to kind of brighten up the darker areas a bit… <!– s:) –><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="" title="Smile" /><!– s:) –>

I believe you are on the right track….

Well I’m getting closer with the lighting-need to work on the internal spot-back to the visable light tutorial!

Good idea-I’ll give it a try-thanks, KB.

Used a high transparency on the lens and a spot to reflect-to make it look andquot;onandquot;. wanted to paint the inside but need to work on it for a seperate reflector-I think-there were so many faces andamp; points inside. It started out as a exercise with the differant object tools [lathe-etc.] deceided it looked like a flashlight-one of those evolutionary things. I’m sure there is a better way to do the andquot;headandquot; with a smoother inside-
Thanks-KB.

Povray does take a long time to do visible environments. You could probably fake the effect by using a transparent cone coming out from the eminating part of the flashlight, and make sure you don’t let the edges of the cone be visible by using a transparancy map.

It looks like you can see through the lens – if so maybe you could andquot;silverandquot; the inside of the andquot;bulb holderandquot; ? Or is it reflection ?

The visable light takes a bit of time to render – stick with it it is worth the wait (don’t forget to do a small trial render before putting the res. too high <!– s:) –><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="" title="Smile" /><!– s:) –>)

You can use cylinder mapping for the transparancy map and then use uv mapping to place the texture correctly..
Make sure the dark areas of the transparancy maps are on the edges and the lighter (more opaqe) sections of the transparency maps are towards the center of the cone. This idea assumes that you won’t be moving the light cone around like in an animation.

Some of these images look pretty good! remember to set antialias to on.

KB,
The light looks pretty good. I think you are close to what BHoltzman was explaining. You could also try some higher Ambient values on the light to try and brighten it a bit more like the cone on the right.

andnbsp;Looks like I’ve lost the color of the globe when raytracing-does this have to do with the texture of the globe? If I remember I copied it from someones post here. Really like the effects it’s making though! KB

Hello BHoltzman,
andnbsp;Have been trying the translucency map, unless you mean something else, with the cone edges showing, as you pointed out. Is this about what it will look like, or do I need a different andquot;transpancy mapandquot;?
Thanks, KB.
