Transmittance Function Mapping The interaction between light and participating media involves complex physical phenomena including light absorption and scattering. Media such as fog, clouds or smoke feature complex lighting interactions that are intrinsically related to the properties of their constitutive particles. As a result, the radiance transmitted by the medium depends on the varying properties on the entire light paths, which generate soft light shafts and opacity variations. Simulating light scattering in these media usually requires complex offline estimations. Real-time applications are either based on heavy precomputations, limited to homogeneous media or relying on simplistic rendering techniques such as billboards. We propose a generic method for fast estimation of single scattering within participating media. Introducing the concept of Transmittance Function Maps and Uniform Projective Space Sampling, our method leverages graphics hardware for interactive support of dynamic light sources, viewpoints and participating media. Our method also accounts for the shadows cast from solid objects, providing a fullfeatured solution for fast rendering of participating media which potentially embrace the entire scene.
Tech Tip about Pa Window Tint Laws/Regs by ENORMIS in Erie, Pa Penndot FACT SHEET Table X Passenger Cars Must Have 70% Light Transmittance on ALL windows. Basically Penndot Says you are NOT allowed to tint a CAR. Period. Trucks & Multi-Purpose Passenger Vehicles (2) Must Have 70% Light Transmittance on the WINDSHIELD, FRONT SIDE WINDOWS & WINGS, and there is NO REQUIREMENT for the REAR SIDE WINDOWS & WINGS, and REAR WINDOW. (2) For the purpose of this fact sheet, multi-purpose passenger vehicles are defined as those which are built on a truck chassis or are specifically designed for occasional off-road use. Basically Penndot Says there is NO REQUIREMENT on rear windows and you are TOTALLY ALLOWED to tint your SUV, MPV, and Truck as long as the windows are behind the driver. Ohio Allows ANY Window tint Behind the driver on ANY vehicle. (Cars are Same as SUV's) New York Tint Laws are strict like Pa BUT, New York Allows ANY tint on a Car's BACK window.

34 mm Neutral Buy from Amazon CA Site www.amazon.ca Product Description 34 mm Neutral Four main uses:1.Enables slow shutter speeds to be used, especially with high-speed films, allowing film to record movement in subjects such as waterfalls, clouds, or cars.2.Decrease depth of field by allowing wider apertures to be used, in turn helping to separate subjects from their background.3.Decrease the effective ISO of high-speed film (above ISO 400) and allow it to be used outdoors in bright situations.4.To allow picture and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes that can cause overexposure.ND2:reduce one gear of the aperture,average transmittance of 50%ND4:reduce two gear of the aperture,average transmittance of 25%ND8:reduce three gear of the aperture,average transmittance of 12.5% Disclosure: Orchid is a participant in the Amazon.ca, Inc.

Rear Projection Material Review - Prolight Films Dark Gray Here I reviewed a film from Prolight Films based here in California. This is their Dark Gray Rear Projection flexible film, with a gain of 3, light transmittance of 55% and a viewing angle of 125 degrees. There is little to no hot spot created from the projector which is really nice. Viewing angles are good for horizontal setups as you see in the video. Infrared light transmittance is also good, allowing easy blob formation for objects placed on the touch surface. The touch setup seen in the video is the same box used to make the HOW TO on building a Rear DI setup created previously ( Peau Productions website: Prolight Fims website:

How does a spectrophotometer work? (interactive eLearning tools) This short animation demonstrates the inner workings of a spectrophotometer. Here's how a spectrophotometer works. A lamp provides the source of light. The beam of light strikes the diffraction grating, which works like a prism and separates the light into its component wavelengths. The grating is rotated so that only a specific wavelength of light reaches the exit slit. Then the light interacts with the sample. From this point, the detector measures the transmittance and absorbance of the sample. Transmittance refers to the amount of light that passes completely through the sample and strikes the detector. Absorbance is a measurement of light that is absorbed by the sample. The detector senses the light being transmitted through the sample and converts this information into a digital display.

Double PL filter effect to reduce light transmittance I used two 58mm PL filters to reduce the light transmittance mainly for the purpose of taking long exposure day time shots from Canon 550D. By rotating a PL filter on the top of other gradually and evenly changes light transmittance from 70% transmission to 0% transmission.
