derek Posted September 30, 2009 Posted September 30, 2009 Is this possible? And does anyone have any examples of their work? I've been trying for a while with limited results, I came across this tutorial for Kerkythea: http://www.kerkythea.net/joomla/index.php?option=com_content&task=view&id=23&Itemid=60 (bottom of the page) and I was quite impressed with the results there. I was just wondering is it possible to produce similar results in autocad 2009? Obviously Im no expert when it comes to rendering so perhaps by following some of the settings, bump maps etc used in the kerkythea example is it possible to produce something similar? Thanks in advance Quote
Cad64 Posted October 3, 2009 Posted October 3, 2009 Yes it's possible. Just browse through the Showcase section and take a look at threads like these: http://www.cadtutor.net/forum/showthread.php?t=37463 http://www.cadtutor.net/forum/showthread.php?t=40220 Quote
Randolph Posted October 4, 2009 Posted October 4, 2009 Well, the example is a little pool. With sea and sky, I'd rather go for a landscape generator like terragen and import your AutoCAD data or mix in postproduction. http://www.planetside.co.uk/terragen/productmain.shtml Else, Maya's Ocean is a good choice if available.

derek Posted October 5, 2009 Author Posted October 5, 2009 Ok, Ive picked up a few things from the showcase threads (thanks CAD64) and this is where Im at. I've attached a cut-off view of the bottom of an offshore platform, I cant show the top of the platform for commercial reasons but since my question only relates to realistic rendering of water it shouldn't be a problem. Basically I've got 2 3D faces sitting on top of one another, the first is simply for colour of the ocean, the one on top has all the bump mapping, opacity & reflections settings checked. Im still looking to improve the look of my water, its not as good as some I have seen on here. My ideas are: 1. To re-draw the top face as a random mesh to give the surface of the water a rougher sea like texture. 2. Someone on here helps me with manupulation of the settings of bump maps, diffuse maps etc until it looks spot on. Please any suggestions on how to improve my rendering of water and also bear in mind Im a noob and using autocad 2009 only. Thanks alot Quote
Randolph Posted October 5, 2009 Posted October 5, 2009 Make a huge half dome beneath the water. Give it a blue to almost black gradient. Make the water slightly transparent. You could model a surface with waves for the region around the building. And - most important - go for the fog function to get a white haze on the horizon. Set a blue directional light opposite to the sun light with shadows off. All in all, don't go for too much realism, as long as the building has no concrete or steel textures. Furthermore, Terragen is freeware. Why not download, learn 1 h and save lots of work for a better result ... Quote

Yes, it is free, but it does have restrictions on image size and quality. If you want to render out an image with high resolution and anti-aliasing, you have to purchase the full version. But the good news is the price is very reasonable. Quote

Should I draw the half dome with the point of the circle around the building/platform then? Arcing out and away from in to make the water appear dark and with shadows? How do I set the fog function? I know how to call it up but I normally dont see much change when I play with the settings? Is there an optimum setting for distance, percentages etc? Thanks very much for the input Quote
Randolph Posted October 5, 2009 Posted October 5, 2009 Yes, and you should construct something of the platform below the water (if your modle stops there). If you want to go further, activate refractions. Global illumination if available. With the optimum distance for the fog, i can't help you, i would have to play with the settings as well. Quote
derek Posted October 13, 2009 Author Posted October 13, 2009 Finally got something I'm reasonably happy with. I know theres still some things I could do, like play around with the texture & bump map a little more. Also darken up the tones a little but all in all I'm glad I've finally got something that approximates a render of water. Thanks to all who helped. Again apologies cant show the full image due to company policy. Quote
Randolph Posted October 13, 2009 Posted October 13, 2009 well, i'd say the water looks quite good - congratulations. i think you can leave it as it is. next thing to do: the platform itself. with this strange baby****-yellow, it's impossible to tell what material it should be. seems to be some plastic material. either it is steel, or concrete, and then i think it should look somehow that way. go here to find some textures http://www.arroway-textures.com/de/products/concrete-1/contents if you have to save the money, you can rightclick on the textures and save the preview.

It's a steel monopile, didnt see any textures for that on the site. The material i used was just a photo I have of a similar monopile which has already been constructed. Other than that I drew up a blank, because yeah it is like steel in texture but these things will be painted yellow to comply with offshore structure regulations. Quote
Randolph Posted October 16, 2009 Posted October 16, 2009 OK, in yellow - not in babygagabrownishyellow. So go for a blinn/phong/metal shader, set the colour to RGB 255,255,0 and turn on reflections at about 10-15 percent. You should see some reflections of the water then. If you want to achieve a thick paint layer, you can also go for a plastic/anisotropic material. Anyhow, set highlight/specular colour to 255,255,255. Thus, you can achieve reflections of sunlight. Anyhow, make the column bright, clean and friendly looking. Quote
