- Face Scannning Services with Standard Deviation In partnership with Standard Deviation (sdeviation.com), we are very excited to announce new face scanning services in Los Angeles! These services are:3D Photometric Stereo Face Scanning4D Face CaptureHeadcam Face Capture
- Command-Line Photogrammetry with AliceVision (Tutorial/Guide) Do you need to automate a huge number of photogrammetry scans? Then I have some good news for you.
- Minimal Color Grading Tools As you have probably noticed, there are a lot of color correction algorithms out there. It can be a bit daunting to figure out the best combination of tools to use on a given project. I’ve personally gone through many iterations of trying different things in different orders and over time I’ve settled on a few key features.
- Filmic Tonemapping with Piecewise Power Curves It’s been a long while since the original posts on Filmic Tonemapping, and it is time for an update. For newcomers, the basic premise of Filmic Tonemapping is to simulate the tone curve of film in our images, with a shoulder and a toe. In the image above, the left side is a pure linear tonemap and the right side uses a filmic curve.
- Cheating Physically Based Light Intensity (IRL) One question that I struggle with in PBR is: How physically accurate should we be? In general, I’m a PBR beliver in that we should try to model CG surfaces to behave like real surfaces and we should try to model lights to act like real lights. But what about the times when an artist comes to you asking to do something that is not physically realistic in order to make it look artistically better? As luck would have it, I got a chance to look at film set for a big budget TV show recently. Or rather, the film set came to me.
- A new year, a new server. Happy new year to everyone. As you might have noticed, I’ve gotten an early start on my new year’s resolution of overhauling my web page.
- A perfect display needs 4x the resolution of Visual Acuity (maybe) In discussing what a “perfect” display would be, the common view could be said like this:
- Visual Acuity is not "What the eye can see" What resolution does a display need to have before you can not perceive aliasing? The discussion usually goes something like this:
- The Uncanny Valley as FFA Rejection Why does the Uncanny Valley exist? Why is it so difficult to cross? Why is it that all the tricks we use for making CG things like rocks, houses, and cars do not work for faces? The usual answer is something along the lines of “Faces are hard” or “As human being we are experts at understanding faces”. That just tells us the symptom, not the cause. What is the real, physiological reason why the Uncanny Valley exists?
