In a research effort we call Infinite Nature, we show that computers can learn to generate such rich 3D experiences simply by viewing nature videos and photographs. Our latest work on this theme, InfiniteNature-Zero (presented at ECCV 2022) can produce high-resolution, high-quality flythroughs starting from a single seed image, using a system trained only on still photographs, a breakthrough capability not seen before. We call the underlying research problem perpetual view generation: given a single input view of a scene, how can we synthesize a photorealistic set of output views corresponding to an arbitrarily long, user-controlled 3D path through that scene? Perpetual view generation is very challenging because the system must generate new content on the other side of large landmarks (e.g., mountains), and render that new content with high realism and in high resolution.

The newest home video projector from BenQ is called the W1070. Sporting native 1080p resolution and a max light output of 2,000 lumens, the W1070 has the pixels to show HD moves in their native resolution and the power to light up your living room, even if you can't get the space completely dark. Home video projectors, as the name implies, are designed for multipurpose use in family rooms and living rooms; i.e. places other than a home theater. They are more likely to have higher light output, onboard speakers, and more modest contrast than home theater projectors since black level is less of a concern when ambient light is present. Conversely, home theater projectors are optimized for darkened rooms and typically have very high contrast.The Viewing ExperienceThe W1070 defaults to Dynamic mode, which like other projectors' Dynamic modes is very bright and very green. Dynamic mode will be useful any time you need to prioritize light output over the projector's other qualities, such as contrast and color saturation, as these take a beating in order to increase overall power. The projector's two other modes are Standard and Cinema. Standard and Cinema modes both have better color balance than Dynamic mode, with Standard intentionally maintaining a slightly colder overall color temperature. In terms of light output, the two are about equal.As a whole, the picture produced by the W1070 is bright, clear, and perfect for the living room. The picture is sharp and detailed thanks to the W1070's full-HD 1920x1080 native resolution. Thanks to the projector's brightness and solid dynamic range, shadow detail is maintained in all but the brightest ambient light. Perhaps the most unique quality of the W1070 is 3D compatibility, which is something normally not found on home video projectors. While 3D is certainly appealing to many projector buyers, it is hard to square the W1070's 3D compatibility with its intended use as a living room projector. However this just expands the W1070's potential uses beyond daytime entertainment into night-time 3D.
Key Features2D image quality. While the W1070 isn't a projector with a lot of bells or whistles on it, the projector's 2D image quality is excellent. The projector comes out of the box with three perfectly usable 2D image modes, a 3D mode, two locked ISF modes that become available after calibration, plus three User image modes for customization. These modes help the projector cope with the myriad different situations in which a home video projector might be used, from a darkened theater-type environment to a bright living room on a sunny Sunday afternoon.3D Performance. The W1070 uses the DLP Link system to display Full HD 3D, meaning that the image is punctuated by white light pulses which are used to sync with active shutter 3D glasses. This has both positive and negative consequences. A positive consequence is that DLP-Link systems tend to be very low in crosstalk, and indeed the W1070 had no visible crosstalk during our testing. On the other hand, DLP Link glasses tend to lose synchronization more easily than either infrared-sync or radio-sync glasses, which can be a concern in any environment where people get up and move around. Either way, the W1070 is one of the few home video projectors to feature Full HD 3D.With decent out-of-the-box color and respectable contrast, the W1070 is a great little projector for entertaining in your home. By far the best part of the image is its natural sharpness and clarity. This isn't just due to the projector's 1080p pixel matrix, either; the W1070 has a razor-sharp image even for an HD projector--especially one in this price range.Long life. The W1070's long-life lamp makes it an attractive projector to serve as a partial TV replacement. Lamp life is estimated at 3,500 hours in full power mode and up to 6,000 hours in Eco or SmartEco mode, which is considerably longer than comparable projectors. This is in part because the W1070 is capable of reducing lamp power by up to 70% using the projector's SmartEco function, which dims the lamp output to a level appropriate for the content on screen at the time of selection. There's no way to make an arbitrary brightness selection, which is unfortunate, but the concept itself is useful when you don't need a lot of light.Onboard audio. Part of the allure of home video projectors is their use as TV replacements, and TV replacements need some kind of onboard sound capability. The W1070 doesn't have much of a speaker system; it has a single 10W speaker rather than the stereo sound that some competitors offer. But that one speaker doesn't suffer from distortion or the tinny character that plagues many small speakers. Indeed, with the volume cranked, we found the single speaker more than adequate for an audience of eight in a large living room. Placement flexibility. The W1070's manual zoom lens has a 1.3:1 ratio, and can display a 100" diagonal image from 8' 4" to 10' 11". That's about standard for this class of projector. What is not standard is the projector's vertical lens shift, which gives you the ability to move the projected image up or down by about 10% of the image's height. The range is such that, at the bottom, the bottom edge of the projected image is level with the lens centerline, and at the top it has an upward throw angle equivalent to roughly 20% of the image's height. This makes table mounting and ceiling mounting the most realistic options, while a rear shelf mount is more or less out of the question both due to lens shift and zoom concerns.6X Speed Color Wheel. The W1070 has a six-segment color wheel in the theater-optimized RGBRGB configuration. This wheel layout maximizes color without artificially boosting white, and is preferred for its ability to render natural color. What's more, the wheel gives an effective refresh rate of six times per frame. This should eliminate color separation artifacts (rainbows) for all but the most hypersensitive of viewers.
In the 2nd chapter, we will dive into some theory behind natural environments, different types of landscapes, we will talk about dunes, clouds, erosion and all those wonderful processes happening in the nature, forming the beautiful landscapes we will try to recreate.
Rich textures with finishes inspired by nature are gaining more and more prominence in interior design and architectural projects. In line with this philosophy in which the surface is as relevant as the material itself or the selected colour range, and as a result of investment in R&D, 3DFIT is born.
When you notice 3D data losing quality, like when the camera is at a low angle, try rendering at double the standard resolution (3840x2160). The resulting render should have significantly more detail. You can then downscale the render back to 1080p in the editing software of your choice. 2ff7e9595c
