3D Scanning on a Budget In this very short article I want to show you how to achieve some fairly decent 3D scans for under $200 using AgiSofts PhotoScan software.. The software its self is very simple and the photos can be taken from any positions, providing that an object to be reconstructed is visible on at least two of the images. Both image alignment and 3D model reconstruction is fully automated so there is no need for lengthy calibration processes. For this example I've used my good friend and co worker Andy Turner you can check out some of his animation work here Supermachine Here you can see Ive taken 9 photographs using my Nikon D80. No calibration or markers / tracking points needed And this is what it comes up with after about 10 minutes of processing the photographs The geometry can be exported and loaded into zbrush as an obj.. A close up of the raw scan data. With the background polygons removed we are left with just the head The head model above with the colour map applied

Our eyes can sometimes deveive us. Everyone's eyes see slightly different colors. One person will see a purple color, while another will see a blue. Also, depending on the monitor that you own, you may see a different color than other computers. Also, these color pallettes are used professionally. You can also take colors from the lips, eyes and hair to help with realistic color of those.

Smart3DCapture Z4 Beta Testing By: Ryan Kingslien (Nudity) Thank you Pixologic for another amazing update to ZBrush! It was truly a pleasure to be on the other end of the beta team and to see ZBrush with fresh eyes.For those just getting their heads around ZBrush 4, here is a list of my favorite features:Shadowbox: The single biggest update for me. Quickly create sculptable geometry using nothing more than a mask. I've created a presentation of how to use Shadowbox to create an ecorche of your sculpted figure. Happy ZBrushing to everyone!
PhotoScan - Tips and Tricks - Agisoft This page contains practical advices on the use of PhotoScan, as well as other information that may be useful to the users. Taking Photos Zenithal and/or obliques? It is better to capture only zenithal photos, yet the obliques ones are processed correctly by PhotoScan and almost do not influence the quality of the reconstruction results. Aligning Photos What is the basic principle behind PhotoScan matching strategy? PhotoScan searches for interest points on every image and studies the local neighborhood of every point found. Most photos aligned well, but a few photos failed to align properly. Incorrect photo alignment is usually a result of poor overlap or insufficient amount of texture details on the object surface. The results of photo alignment step are poor:( What could I do? The problem could be caused by the lack of overlap between the photos. Can I improve the alignment results for a fixed multi camera rig? 1. 1. Optimization Building Model What does the Face Count parameter mean? 1.
Artist in Action :: Scott Eaton Introduction The human figure has been central to the creation of art for thousands of years. Starting with the ancient Greeks and Romans, artists sought perfection in representation of the figure. Recently interest has reemerged, and especially in the applied digital arts - games, film, and commercials – where there are production demands for figurative skills. With the rise of modernism, representational figurative art fell far out of fashion and for the better part of a century art schools neglected -- if not discouraged -- it in favor of abstraction. Three approaches to Figure Sculpting Over the course of the next months we are going to work through three approaches to figurative sculpture in ZBrush. 1. We start working from reference because it builds confidence in seeing and building forms, it gives immediate feedback on how close we get to our goal, and the reference doesn’t move (or get paid, like a model). We can take our time and work patiently.
