Media?

Looks pretty good!! I got similar effects trying a few things. But since I last posted here, I’ve actually learned quite a bit about the effects I was trying to acheive and am using atmosphere and media alittle more now. Problem is, as I stated in a different post, my machine is antique in its abilities, so rendering with these statements are almost impossible unless I let my system run for a week or so. But I’m building a new one that should let me do what I want with faster results. <!– s:D –><img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt="" title="Very Happy" /><!– s:D –> If I get a chance, I’ll do some examples to show. I am really trying to finish the two projects I have going in POV right now to post. Problem is, I may actually be making something I may not be able to render. ( limited memory!!)

I don’t think this has been covered before on the forum, and I can’t find anything in the help files, either.

3DC doesn’t seem to have a function to use POVRay andquot;mediaandquot; statements to accomplish such things as smoke, fire, fog, etc. andnbsp;I notice that you can use 3DC to define atmospheric particles for the whole scene, but not for the interiors of specific objects. andnbsp;It’s a pretty nifty function to have.

Are there any plans to incorporate this function in 3DC? andnbsp;Is it infeasible?

Yeah, the atmospheric particles use a version of the andquot;mediaandquot; statement.

The media statement has lots and lots of parameters that can be set. . .I had the thought that it might be nice to be able to bring up just a text box where one could add code that would be inserted inside an object’s definition code, so that we could use code to do things that might not be implemented in 3DC. andnbsp;This could be helpful because you would just have to add the text-box, and then not worry about all the other POV features, since we would still be able to use them if we know the code. andnbsp;Or, instead of making a special interface modification for the POV code entry, could it be done by scripting (ie using the Component Script function)? andnbsp;Maybe this sort of thing would be more specialized than you would like it to be, which is fine.

I also realize that I can export a scene in .pov format and edit the code from there, but I’m thinking specifically about animations where it would be impractical to export and edit every frame.

andquot;Atmosphereandquot; does use Media if I recall right. I couldn’t figure out how to use Media to put water into bottles etc. More correctly, I couldn’t figure out how to define it in 3DC.

Hey there Troub!!
Was wondering if , when you have some time, you could give me some help with media statements in POV. I can get it to work, but I cant get a good effect. With the street scene I posted, I really wanted to use media instead of fog so that the spot lights ( used in the street lights) would show a ‘light cone’. I wont go into details right now, but if you get some time, I would like to see if you have it better than I do. <!– s:D –><img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt="" title="Very Happy" /><!– s:D –> I have a basic understanding of the three parameters, but dont seem to get a good effect. I am going to play alittle with media this weekend, but if you have any suggestions, please let me know. Thanks!!

Hey blaydrnnr. . .to get your atmosphere setting to work for light cones and such, you would probably be able to use the 3DC built-in atmosphere settings. They’re in File-andgt;Properties under the ‘Atmosphere’ group. Those controls seem to work pretty well for me to define particles for a whole scene. Media statements can also be used, however, as a property of an object to ‘fill’ the object with some kind of particle effect. I’ve done this to create nice fireballs, etc. The POV help files have all the information you’d ever need regarding media statements and their parameters. I think for ‘fogging’ up a whole scene, the 3DC scene properties that I mentioned earlier would be easiest. Make sure your lights have ‘cast shadow’ selected, also.

If you have any questions or want any more information, feel free to start a private topic with me (I guess that’s like on other message boards where you can send users private messages?) or send me an email if my address shows up in my profile.

Hi Troub,
Thanks for the offer, I will most likely take you up on it. I have looked at the help files, but they dont really help much. I use them to actually use the statement, but setting the parameters to get a good effect was rough. As far as using the atmosphere in 3DC, anytime I use it in 3DC, my system slows to a crawl. Alot of the times, if I have it working in 3DC, I get lock ups. Thats why these days, I try to do most of the lighting and atmoshperic effects in POV. The new scene I’m working on has lots of distance veiws in it, and I would like to use media for this instead of fog. (I dont think fog reacts with light in POV if I remember right )Thanks again for the help and the offer Troub!!! Talk soon!! <!– s:D –><img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt="" title="Very Happy" /><!– s:D –>

Hey guys,
I know this is an old topic, but I was goofing off and thought I would experiment with your ideas. I created a real quickie street scene with one street light, placed a spotlight inside the fixture, and used a semi-transparent cyliner to get a ‘light cone’ effect. Here’s what it looks like in 3DC

Next I exported to PovRay, adjusted the spot light position, intensity, etc., then the transparency amount of the ‘cone of light’, and finally reset the intensity of the other scene lights or remarked them out. Here’s what it looks like in Pov.

P.S.
I used no atmospheric conditions such as fog, and no media statements. This might be cheating a little but it looks ok I think. <!– s:) –><img src="{SMILIES_PATH}/icon_e_smile.gif" alt="" title="Smile" /><!– s:) –>
