3D Photo Editing Software DAVID 3D Scanner RepRap RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend... RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was voted the most significant 3D-printed object in 2017.
Simple3D -- 3D Scanners, Digitizers, and Software for 3D Models and Measurements 2D to 3D from any movie easily Sometimes it's difficult for people to get their head round the concept of window violation, but when you do understand it, it will be quite clear. Basically it is when part of the picture appears to be protruding towards you beyond the borders of the picture, sometimes known as 'pop' or 'through the window' (TTW), but at the same time is cut off by the border. This is very confusing to the brain as it is unnatural. So for example, in your pic of Canary Wharf, imagine that the borders of the window are a real window frame and you are looking at the view. If the buildings actually appeared to be partly inside the room, that would be clearly impossible but that is what your picture appears to show. Using SPM, the whole picture can be pushed further away by making sure that the L/R images coincide on the nearest part of the subject. Where an object doesn't intersect any part of the border, it can be allowed to come forward of the window to give a dramatic 'pop' effect, without causing a WV.
3DP Materials Review The list not exhaustive — and it is certain to keep growing over time: Wood: The New-comer The newcomer in the group of 3Dprinting filament materials is wood. What is positive about it is that the print texture is simply beautiful and it hides print layers nicely, without making extremely thin layers. The only brand available at the moment is LAYWOOD, and the manufacturers spent over a year on research and development of the material. PLA: The Eco-friendly Filament Polylactic acid (PLA) is one of the most common filaments used in the home 3Dprinting community. PLA is strong and resists UV light better than it's main popular alternative, the non-biodegradable ABS plastic. It should be noted that if you are using PLA for dining applications such as cups or plates, some of the colour pigments may contain toxins. PLA in its natural state is transparent, but colour choices for PLA vary making it suitable for creating toys and artistic items. ABS: Fantastic Plastic PVA: Water-soluble plastic
ECE 4760 Final Project: 3D Scanner Ryan Dunn (rjd38 at cornell.edu) Dale Taylor (dat38 at cornell.edu) Introduction This goal of this project is to make an effective, low-cost 3D scanner. Summary Our project implements the hardware necessary for a laser triangulation 3D scanner as well as a PC user interface for controlling the scanner and acquiring data via an Ethernet connection. High Level Design Rationale While 3D scanners are by no means new technology, they are still well out of the price range of the average individual or small business owner. 3D Laser Triangulation Scanning The way that a 3D Laser Triangulation Scanner works can be easily explained using simple geometry and trigonometry. Laser Triangulation Logical Structure In order to extract physical coordinates from a contour line like the one explained in the math above, we will use a camera and a laser line. Digitally reconstructing the object and processing the images from the camera to extract the contour lines is computationally expensive. Mega644 Camera Ethernet

CMIS Research - Image Analysis Activities - Applications/Work Overview - 3D Flatbed Scanner 3D Flatbed Scanner 1. Summary CSIRO Mathematics, Informatics and Statistics (CMIS) has developed an innovative flatbed scanning and imaging system based on a method of scanning the visible surfaces of small 3D objects, for enabling 3D viewing applications and surface measurements. CSIRO's software can be used to automatically reconstruct 3D object surfaces for measurement and 3D image display in personal and business applications. 2. Representing the third largest segment of the PC peripherals market, scanners transform hard-copy pictures or text into digital data for use in a wide range of applications. CSIRO's proprietary imaging technology may be applied, to extend the scanning capabilities, of scanner, photocopier and fax machines, to include 3D images of the visible surfaces of small and low depth of field objects capable of being placed on a scanner. 3. Or if you have an idea for different applications, please let us know. 4. 5. 6. 7. 8. 9. 10. C. Contacts
Build A Quadcopter From Scratch - Hardware Overview In this article I will be talking about quadcopter components and how to choose them. This is part of the tutorial series on how to build a quadcopter. In the next post I will be talking about software, how to go about the algorithm and programming. If you are planning on building a quadcopter but not sure how, this is the right place for you. Doing research is pretty boring, so I am trying to put together a comprehensive tutorial about quadcopter, hope it helps you as much as it helped me. Building a quadcopter from scratch takes a lot of time and effort. For more tutorials, check out this list. This blog post is divided into a three parts What is a Quadcopter and How It WorkQuadcopter Components IntroductionConclusion A QuadCopter is a helicopter with four rotors, so it’s also known as quadrotor. The Quadcopters exist in many different sizes. For example, to roll or pitch, one rotor’s thrust is decreased and the opposite rotor’s thrust is increased by the same amount. Frame Propellers
Mozilla Firefox 3-D Printing Will Change the World To anyone who hasn’t seen it demonstrated, 3-D printing sounds futuristic—like the meals that materialized in the Jetsons’ oven at the touch of a keypad. But the technology is quite straightforward: It is a small evolutionary step from spraying toner on paper to putting down layers of something more substantial (such as plastic resin) until the layers add up to an object. And yet, by enabling a machine to produce objects of any shape, on the spot and as needed, 3-D printing really is ushering in a new era. As applications of the technology expand and prices drop, the first big implication is that more goods will be manufactured at or close to their point of purchase or consumption. Another implication is that goods will be infinitely more customized, because altering them won’t require retooling, only tweaking the instructions in the software. China won’t be a loser in the new era, but it will have to give up on being the world’s manufacturing powerhouse.
