Stereoscopic Rendering
Jun 10th
Here is a stereoscopic render I did for a lake cabin. You’ll of coarse need a pair of stereo red/cyan glasses to enjoy the 3rd dimension.
Stereoscopy, stereoscopic imaging or 3-D (three-dimensional) imaging is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. The illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. Many 3D displays use this method to convey images. It was first invented by Sir Charles Wheatstone in 1838. Stereoscopy is used in photogrammetry and also for entertainment through the production of stereograms. Stereoscopy is useful in viewing images rendered from large multi-dimensional data sets such as are produced by experimental data. Modern industrial three dimensional photography may use 3D scanners to detect and record 3 dimensional information. The 3 dimensional depth information can be reconstructed from two images using a computer by corresponding the pixels in the left and right images. Solving the Correspondence problem in the field of Computer Vision aims to create meaningful depth information from two images.
Traditional stereoscopic photography consists of creating a 3-D illusion starting from a pair of 2-D images. The easiest way to create depth perception in the brain is to provide to the eyes of the viewer two different images, representing two perspectives of the same object, with a minor deviation similar to the perspectives that both eyes naturally receive in binocular vision.

Lake Cabin Illustration
Jun 3rd
Here is a lake cabin illustration that I just completed. The model was created in 3DS MAX Design 2011 and rendered using the V-Ray render engine. If you have any technical question feel free to post them here.
Composition is one of the most misunderstood concepts in any form of artwork. It has been said that you can be the greatest painter in the world, but if you don’t know how to compose properly, your painting will fall apart and the same goes for digital art/illustrations/renders.
Like all illustrations of mine, this one started off in my head. First I decide what would make this image special and I decide on a focal point. These cabins are on a lake, very close to the water, and have windows and a deck facing the South. I like to play with contrast so I typically place my camera about 45 degrees from my light source (in plan), with the focal point being in the light. Since the cabins are on the lake facing South I know that you would see the sunrise so I took advantage of the glass on the sliding windows. I chose the sunrise in the reflection as my focal point.
To bring the viewers eye to my focal point (composition is really about moving the viewer’s eye) I placed the boat in the foreground, pointing towards my focal point. The boat was tipped slightly away from the camera so it wouldn’t bring so much attention to itself. I used yellow on the boat to help the viewer up into the image knowing the eye associates colors and the sunrise in the reflection is yellow too. The focal point is also 1/3 to the left of center and about 1/3 below center, which is were the eye is naturally drawn to in an image. I usually have my horizon lower, but I wanted at least as much blue water as blue sky (the water and sky are blue, which are complementary colors to my focal so it brings the illustration into balance).
Below are some screen grabs of my V-Ray settings:
VFB Frame Buffer
Global Switches
Antialising
Image Sampler
Environment
Color Mapping
Camera Type
GI
Brute Force
Light Cache
Caustics
DMC
Displacement
Systems
Elements
V-Ray Camera
HDRI
Gamma
I can comfortably say that I have never used the same settings for any 2 scenes so these settings might not work for you, but it might be a good starting point. I am running a render farm with 90Gb of RAM and 24 processors so unless you have an equivalent farm these settings might be to high for you.

IES Releases Revit 2011 Compatible VE Plug-in For Environmental Performance Analysis
May 18th
BOSTON, May 13, 2010 (BUSINESS WIRE) — Integrated Environmental Solutions (IES), a provider of integrated performance analysis software and consulting services for sustainable building design, today released an updated version of its VE plug-in to Autodesk Revit Architecture and MEP. The plug-in allows Revit 2011 users to easily export models into any of the IES Virtual Environment (VE) environmental building performance analysis tools; VE-Ware, VE-Toolkits, VE-Gaia and VE-Pro. Removing the need to re-build models, the IES plug-in greatly enhances design workflow and simulation accuracy, bringing comprehensive and integrated analysis options for all design stages to the Building Information Modelling (BIM) process.
This new IES VE plug-in now supports Revit 2008, 2009, 2010 and 2011. It offers enhanced model transfer capabilities and can handle challenging and complex geometry, as well as offering users the option to choose the level of geometry detail exported from the basic, to how shading surfaces are handled, to whether curtain wall mullions are counted as shading surfaces. The VE sets no explicit limits on the number of surfaces that it can import. This important capacity gives users ultimate control over geometry detail used for performance analysis and energy modelling within IES tools. Highly detailed curtain walling systems, multi-faceted shading surfaces and mullions, and additional complex shapes and junctions, can all be handled.
The IES VE tools offer a range of powerful performance assessment options suitable for all different design stages and user experience-level, while the integrated nature of the suite allows the interrelationships between energy use, CO2 emissions, solar, lighting, airflow and system design to be taken into account and analysed at a whole building level. Building mass and form, the climate, natural resource availability, occupancy, materials and services can all be taken into account to ‘virtually’ test the feasibility of different energy saving strategies and low carbon/ renewable technologies.
IES also offers a range of automated tools which assist with the LEED and GreenStar rating systems, and compliance with UK energy reduction and Performance Certificate regulations.
The latest version of the IES VE Revit Plug-in can be downloaded at http://www.iesve.com/Software/Model-Building/Revit-plug-in

Analyze the effects of solar radiation on various surfaces of your conceptual building model.
May 16th
Use the Autodesk Solar Radiation Technology Preview for Revit 2011 to understand and quantify solar radiation on various surfaces of your conceptual building model.
Using the Autodesk Solar Radiation Technology Preview during the conceptual design stage of your project can help you make informed design decisions about building shape, orientation, and shading strategies early on when changes are least expensive.
The technology preview uses the geometry of conceptual massing elements from Revit and calculates the amount of solar radiation hitting the selected surfaces of the massing shapes, based on location and weather data. It is possible to display the distribution and availability of solar radiation over an entire building or even a city block. This can be particularly useful when considering shading requirements or assessing the best areas to place photovoltaics for maximum collection.
The Autodesk Solar Radiation Technology Preview is modeless and delivers an integrated experience within the Revit environment. This experience is made possible by the Analysis Visualization Framework, Dynamic Model Update, and other new API’s made available with the Autodesk Revit 2011 family of products.
This technology preview is a limited term release to seek customer feedback on its performance and expires on November 5th, 2010.

Zebra Imaging’s realistic holographic 3D visualization displays
May 13th
It doesn’t matter how good 3D gets in games and imaging packages because there will always be occasions where someone wants to see an actual physical model of say, a building, landscape, or product. When requested, designers usually turn to modeling such items and then transporting it to the client. That can be both a costly and time-consuming task.
Zebra Imaging has a very cool alternative, however. The company came up with a system that prints a holographic color image on to a 2D display. As you can see in the two included videos, what you get is a 3D model but in an easy-to-carry plastic sheet format.
In order to see the display you need a light source above it. Zebra can supply a stand integrating such a light if necessary. There’s also a selection of screen sizes to choose from starting at 12 x 12 inches and going right up to 24 x 36 inches.
These displays are already useful in industries such as architecture, landscaping, and within the military. I can also see technology manufacturers using them to show off early gadget concepts rather than producing the actual models because it is simply cheaper to do.
You can see five more videos of these holographic displays in action at the Zebra Imaging Holographic Gallery.
Z-Depth
Apr 2nd
Below you’ll see a Z-Depth pass, yet another trick that allows you to do some post production work on your illustration. The Z-Depth pass allows you to quickly mimic a cameras depth-of-field lens trick. Gaussian blur in post allows you, while using the z-depth channel, to control the blur from light to dark. Doing this allows you to have a foreground, which is important for your composition, but it will not overpower your illustrations focal point.
Ambient Occlusion
Apr 2nd
Ambient = Dark
Diffuses = Light
An Ambient Occlusion pass returns a gray scale image with intersecting geometry darker. This technique allows you to do some post production using layer manipulation. Revit 2011 has some built in Ambient Occlusion capabilities so be on a lookout in the next release.
The below image was created via a script and I use this technique on almost all of my work. It gives your illustration a more realistic feel. This is also how I create the museum board stills and animation.
