    A lot of nice renders coming on here lately.

    This was an attempt to see if the camera in Bryce could be made to sit half in and half out of the volume water plane. You will probably have seen the pictures where the camera is submersed in water and the picture shows the above and below scene at the same time. After hours of fiddling with it I gave up as it wont :) It comes close but even moving it by 0.0001 up or down either takes it under or above the surface. Not unless Horo or David have already done it and can let us into the secret :)

    Anyway this is as close as I can get it.

    Beneath the Ship

    Yes here is a challenge I have faced in the past when I made this image http://countrytraveleronline.com/wp-content/uploads/2010/07/finders-poster.jpg

    The "trick" is to use a solid terrain instead and position your camera along the edge. You can boolean cut a hole for the terrain and camera combo into an infinite plane and that lets you goto the horizon if you want to. See image 1 for untextured view.

    Image 2 with textures applied and a second transparent cube used as a cutter to remove the back three solid faces of the terrain.

    In the poster image I used the rocks to hide the join between terrain and what lay beyond it. And plants and other details hid any troublesome shadows caused by the cutting.

    @ Fishtales - nice looking scene you have there

    @ David - the dragon scene looks great :)

    @ Horo - that terrain scene looks amazing! :)

    This picture looks very very cool.

    Thank you.

    Your work with the jewellery and eggs is excellent.

    The workaround looks good but it doesn't really have the feel or look that the 'real' pictures have. For all that I still ended up with a half decent image in the end.

    its amazing the effect's you can get with just a tiny bit of bump and the default grey material :)

    A space background and a space ship wouldn't be out of place :)

    @ Fishtales - that's not a bad idea, I will try a few thing's and see what i can come up with :)

    @Sandy: That's a wild looking image.

    @Tim Bateman: My thoughts mirror Sandy's. Actually my first thought was of that image being a lunar landscape of some kind. What you've added it right on the money.

    Horo - another beautiful render

    David - another cool video, thanks

    Fishtales- interesting effect more like a mirrored abstract

    Tim Bateman - as usual lovely renders especially the space one, I must try the default material with bump, Thanks for the tip :)

    That's it, much more space/planet like :-)

    So is the effect you are looking for optical rather than diagrammatic? I'm not familiar with the "real" pictures so it would help if you could point us at one and I'll maybe understand the question better.

    @David - thank you. Gems look great and the method applied to the dragon shows it off nicely.

    @Sandy - not the easiest topic to tackle.

    @Tim - thank you. I agree with you, I'm always amazed how good a terrain can look in default grey if it is at a good resolution and the light right.

    @mermaid010 - thank you.

    A few here.

    Loads here, some better than others.

    Especially the Crocodile one and the first one on this page.

    The problem with Bryce is that even with the waterline level with the centre of the camera 'lens' it is either above or below the waterline even moving it the slightest amount, +0.0001 or -0.0001, instead of splitting the image top and bottom. One way around it is to render the above image and then the below one and combine them in Photoshop but that is adding an extra process that I thought I would cut out :)

    @Sandy - particularly the first link shows what we often forget: air and water have different refraction indices. Some very good examples.

    Today i try to upload a scene file on sharecg. But it does not work, what i am doing wrong ?

    edit: sorry, i have found the error. I have upload the last scene Faberge Egg. The scene is without lights and colors and only for learning.


    If someone wants to have a scene he has seen once, sent me a PM and i will upload the scene on sharecg.

    The knack is to balance the aperture and speed to get enough light from the underwater area and not blow out the air side or introduce too much noise :) If Bryce had allowed the lens to be split top and bottom then adding lights to the underwater part would compensate for any loss of light coming from above. With Bryce it would also be possible to set ideal conditions with good light and clear water. Hmm, I've had a thought on that one. Time for more experimenting :)

    Have added some DOF and some murkyness to the water - as well as modifying the refraction of the cutter.

    The blue cube uses the process as explained in the recent video plus a bit of Horo's Garage Closed HDRI for good measure.

    @David - looks quite good, the water thingy. I'm currently working on the other, expect results per email soon.

    An icasohedron and a sphere is all that was needed. Within the tiny icasohedron is an HDRI that casts light and shadow onto the sphere that is a bit transparent and has some reflection. All stars are connected by lines - though I have no idea where the stars come from. The camera is looking through the GWL (gigantic wide angle fisheye lens) and covers about 300 degrees.

    Re the above/below image. That is brilliant, it looks just as good as the images taken with the cameras.

    I'm way out of the loop on this thread and don't know if Robin Wood's tutorial regarding above/below water renders has been discussed, and if it has, please accept my apologies. This may be helpful: http://www.robinwood.com/Catalog/Technical/BryceTuts/BryceClasses/IBryce5/IBryceLesson5-5.html Again, if this has already been discussed, please forgive me. I'm more of a troll these days. :(

    Nice work, Tim. What are you using for the caustics?

    @ Oroboros - thank's, and i used a square parallel light, and used this image as a gel :)

    Ooh, tile-able too, excellent :)

    I love caustics. Here's an old product image I did for a company launching a new sonar/radar/chart interface. The modelling was all done in SolidWorks (not by me), but as is usually the case, the company needed product images before the product was actually built. So I stuck my hand up and said "Gimme the bits, I'll throw it in Bryce".
