We show the versatility of our method by capturing a variety of materials with both one and two camera input streams and rendering our results on 3D objects under complex illumination.The growing ease with which digital images can be convincingly manipulated and widely distributed on the Internet makes viewers increasingly susceptible to visual misinformation and deception.

The results are in good qualitative agreement with natural joint patterns.

We then apply the method to a set of parallel veins and demonstrate how the variations in thickness of the veins can be represented.

We use deep learning methods to approximate the remaining nonlinear portion.

In the examples we show from production rigs used to animate lead characters, our approach reduces the computational time spent on evaluating deformations by a factor of 5x-10x.

Fractures initiate and grow based on the stress field, and the growing fractures relieve the stress in the mesh.

We show that a wide range of bedding-plane joint networks can be modelled simply by varying the distribution and anisotropy of the initial stress field.The modelled fault network shows both radial and concentric faults.The new method provides an effective means of modelling joint and fault networks that can be imported to the flow simulator.Our preliminary findings support the assertion that people perform poorly at detecting skillful image manipulation, and that they often fail to question the authenticity of images even when primed regarding image forgery through discussion.We found that viewers make credibility evaluation based mainly on non-image cues rather than the content depicted.Fake or manipulated images propagated through the Web and social media have the capacity to deceive, emotionally distress, and influence public opinions and actions.Yet few studies have examined how individuals evaluate the authenticity of images that accompany online stories.Our homography-based video frame alignment method does not require the fiducial markers to be visible in every frame, thereby enabling us to capture larger areas at a closer distance and higher resolution than in previous work.Pixels in the resulting panorama are fit with a BRDF based on a recursive subdivision algorithm, utilizing all the light and view positions obtained from the video.This significant savings allows us to run the complex, film-quality rigs in real-time even when using a CPU-only implementation on a mobile device.We describe a new technique for obtaining a spatially varying BRDF (sv BRDF) of a flat object using printed fiducial markers and a cell phone capable of continuous flash video.
