This app allows you to sculpt in 3D, by using your fingers on your iPhone touchscreen. You can even paint your creation once you have modelled it, although there is no way as yet to export your 3D sculpture. Nonetheless, If this is the way things are going maybe I should get an iPhone after all?

Charles Leo, owner of www.lunarstudio.com, has written an informative article about 3D Architectural rendering. It's a great read if you are considering a career in this field, detailing the pros and cons of working in the 3d visualization industry. I can personally relate to what he says about freelancing and outsourcing!

A rendering done by Charles Leo/Lunarstudio:
FRAMANIP PRO is now is available for download here: http://www.ranchcomputing.com/V_framanip.php It's an animation and image viewer created for 3D animators. It displays individual frame sequences in real time, using your computers RAM.
It can do many things including:
- Display any BMP / TGA / TIF / PNG / JPG / JPEG2000 sequence at any Frames per second rate (FPS).
- Resave all the frames in different file format.
- Resize or crop all the frames of your animation and resave as a new sequence.
- Tell you which frames are missing from your animation sequence.
What I would like to see in the next version is suport for more file formats, such as .rpf/rla etc. and the ability to see just the alpha channel of rendered frames.

Francesco Legrenzi has a great tutorial on his site on how to create 3d clouds using V-Ray. Click here to go to his site and view the tutorial
(He's the Italian dude who wrote the excellent book called: "VRay - THE COMPLETE GUIDE".)

VRoom 1.1 is a plugin for Lightwave that simulates the interiors of buildings and the glass panes through which these interiors are seen, even if there is no interior geometry!
It looks pretty cool - check it out here http://www.euriskostudios.com/es/plugin_pages/vRoom.php

Autodesk is now officially supporting Apple Boot Camp, a component of the Mac OS X operating system that enables customers to run Windows on their Apple Hardware, for users of various Autodesk products, including:
- AutoCAD 2010
- 3ds Max 2010
- 3ds Max Design 2010
- Autodesk Inventor 2010
- Autodesk Revit Architecture 2010
- Autodesk Revit Structure 2010
- Autodesk Revit MEP 2010
This means you will be able run 3ds Max properly on an intel-processor Mac :) Well, it has been possible for a while now, but it is now officially supported...

Relink bitmaps is a maxscript utility that allows you relink all 3ds max and VRay stuff - it's a bit like the standard 3ds max resource collector - just better! You can donload it for free at Colin Senner's site: http://www.colinsenner.com/scripts/relink-bitmaps
The download is free, but if you can, why not give Colin props and make a small donation to help him pay off his student loans?
All 3dsmax supported Bitmap Texture types
Relinks Mental Ray Proxy files
Relinks VRay Proxies (.vrmesh)
Relinks VRayHDRI files
Relinks IES files (including VRayIES files)
Automatically checks for script updates and new versions
250% speed increase from previous versions
Command-line mode available for automating repetative tasks (see documentation on the website)
Configurable default user options saving button clicks and wasted time

The purpose of this tutorial is to show you how to render out a 3D object, with its shadow included in an alpha channel, so that you can composite the 3D object and it's shadow on top of an existing photograph.
You will need to download the "vray shadow matte tutorial.rar" file from: http://www.turbosquid.com/FullPreview/Index.cfm/ID/473854
In this file you will find two 3ds max files, a background photo and some additional info.
Please note that the max file used in this tutorial uses the V-Ray LWF (Linear Work Flow) technique, as described on the chaosgroup forums (www.chaosgroup.com). To use LWF you need to change 3DS Max's Gamma settings - please see the included file called "LWF_gamma_settings.jpg" to see what your settings should be. (You can change the Gamma settings in 3DS Max under: Customize >Preferences.) You also need to change the color mapping in your Vray settings, there are various options for this, I've shown one in the included file "LWF_VRay_Color_Mapping_settings.jpg"
lukx (http://www.lukx.com/) has made a simple video tutorial on LWF, it can be found here: http://rapidshare.com/files/16248248/LWFbyLukx.avi.html
Aversis also has a brilliant tutorial about LWF on his website:
There is also a tutorial on LWF on my blog: http://jg3d.blogspot.com/2008/12/v-ray-lwf-easy-way-for-3d-studio-max.html
Open the file: "vray_shadow_matte_tutorial_start_file.max"
You should see something like this:
We need to load the background photo ("background.jpg") into 3ds max, so that we can match the perspective of the VRayPhysicalCamera01 to the perspective of the background photo. We also need to match the shadows created by VRaySun01 with those in the photograph.
Go to the 3ds max menu bar and chose View>Viewport Background...
Now load the background photo ("background.jpg") as shown in the screenshot below. Remember to select Match bitmap, Display Background and Lock Zoom/Pan, so that the background stays the correct size in the viewport.
Your 3ds max viewports should look like this now:
At this point you could move the Camera and the Sun to make the chair look as though it is sitting correctly on the paving. I've done the basic setup for you already - you can always fine-tune it later if you want to.
Create a Plane object under the chair. This is going to be our shadow matte object, so rename it to "shadow matte". It needs to be approximately 2400 mm x 2400mm big.
Now assign a plain grey VRayMtl to the "shadow matte" plane. I have made a material for you already, it's in the top right corner of the material editor.
Right-click the "shadow matte" object and go into the V-Ray properties of the object:
Select the Matte object checkbox, and change alpha contribution to -1.
Alpha contribution=1 is solid, with no transparency, 0 is transparent by itself, but still shows anything behind it, and -1 is transparent blocking everything behind:
Now to include shadows and their effect in the Alpha channel, you must enable Shadows and Affect Alpha:
Next we need to turn off "Receive GI" in the VRay object properties, so that the shadow's colour is not affected by the light from the VRaySky and VRaySun. (Otherwise it would be blueish in colour):
Change the size of the VRaySun01 size to 13 (this will make the shadows a bit softer).
Click Render and render the scene:
Now save the image as a tiff or tga file with an alpha channel:
All we need to do now is open the image we rendered out and the background photo in Photoshop and comp them together. (Easy if you've done before, not so easy if you haven't :p )
Select the chair and shadow via the alpha channel:
Make the RGB channels active:
Copy the chair and shadow selection to the clipboard (CTRL+C) and paste(CTRL+V) the chair on to the "backround.jpg" image, and place it where you think it fits best...but there is a problem with the shadows:
Don't worry, we can fix this by duplicating the chair layer, and making the bottom layer (the shadow) use linear burn as a blending mode.
Now switch the top chair layer back on (make it visible). We also have to delete the shadow area from the top chair layer:
Just a bit more Photoshopping....
Please note that this might not be the most accurate or beautiful rendering and comp, but I just wanted to show you the basic principal behind using a VRay shadow matte - it's a handy technique to know!
