I decided not to include the Javascript that prevents the camera going through the floor at this scene for performance issues (15% framerate drop).
If you like it, you can check out more examples on how vray texture baking can be used for 3D PDF here: http://soid.active-servers.com/pdf/
Thanks for your nice comments.
I plan to write a detailed tutorial once i have some time.
Till then briefly the steps to take:
-Bake Vray complete in render to texture. To prevent blurring along the pelt seams
save your baked images with alpha channeland and take the following steps in Photoshop to “duplicate” the edge pixels:
-Duplicate you baked image (with applied tranparancy mask)
-Apply gaussian blur (3-5px) to the lower layer
-Clone the lower layer with blur over and over again tomake the blur opaque
-Save as jpg (create a droplet to save time)
-Put the baked Vray complete map into the diffuse map (uv map channel 1, others are not supported).
-Set self illumination to 100%
-Export your scene as .rh.
Export modules are available here:
-Import your .rh file in Acrobat 3D
Supported features:
Diffuse map
Emissive (self illumination) map
Opacity map
Reflection map
Bump map (by Javascript, more about here:http://www.graysonlang.com/acrobat3d/attach3dresource/ )
Multi Subobject material and Material ID
Vertex Colors (Darken on Diffuse)
Smoothing Groups
Unfortunatly it seems so that Adobe will not offer more 3D features regarding the needs for 3D visualisations in the near future. The 3D toolkit from Acrobat 8, which basically is a deep exploration “light” by Right Hemisphere, was replaced by the 3D Reviewer in Acrobat 9, which is an Adobe own Development (without texture support and many other features missing). Additionally 3D PDF is limited to the features of the .u3d which is used internally.
So far to the basics.
Hi Chuck, thanks for all the information, this is really interesting to try it ourselves, we wait for a nice tut in the future, but for now: vamonos entendar todos. Gracias!
I installed a blog for posting my 3Dpdf tutorials: http://3dpdf.blogspot.com/
The first one is about the Texture Baking procedure and getting it into Acrobat 3D.
I hope it helps.
Hi SOid,
I just looked at you realtime pdf GUgenheim and, well impressed! I have managed to complete a few similar projects over the past few years but I’m finding the demand quite weak for this type of product (compared to stills or animations)…
Anyway, the reason I write is I am wondering how you achieved this type of trees. Did you make them yourself? or did you buy them from somewhere? I have been looking for low poly trees like that for years but never found them!!!
Many thanks
Fabrice
Hi Fabrice,
I created the trees on my own, for further details on how, I suggest to visit my opacity bug workaround tutorial.
And yes you are right, Texture Baking creates additional work, but on the other hand you need less computer resources than on high end rendeing, because of pdf’s limited capabilities.
With my tutorials I try to deliver user oriented knowledge to a) attract interest of users they are not into realtime 3D yet, and b), giving timesaving solutions to accelerate the development of 3D graphics for 3Dpdf. Therefore I invite everyone to participate in a discussion, using the comment function, to share knowledge, experience and problems regarding the creation of 3Dpdf’s.
Another tip for reducing of seams, use brute force instead of using irradiance map, you’ll get a better lightmap in less pixels, and wont have to deal with the edge bleeding
