Making Shaders More Physically Plausible
There is a need to develop shaders that not only \look good", but are more physically plausible. From physical and geometric considerations, we review the derivation of a shading equation expressing reeected radiance in terms of incident radiance and the bidirec-tional reeectance distribution function (BRDF). We then examine the connection between this equation and conventional shaders used in ...
متن کاملIs Double Reionization Physically Plausible?
Recent observations of z ∼ 6 quasars and the cosmic microwave background imply a complex history to cosmic reionization. Such a history requires some form of feedback to extend reionization over a long time interval, but the nature of the feedback and how rapidly it operates remain highly uncertain. Here we focus on one aspect of this complexity: which physical processes can cause the global io...
متن کاملEfficient, Physically Plausible Finite Elements
This paper discusses FEM-based simulations of soft bodies in terms of speed and robustness. To be physically plausible, three fundamental laws must be respected: rotational invariance, Newton’s law and Euler’s law. We show that precomputed strain-displacement matrices generate nonphysical torques which can lead to visual artifacts. We then derive the fastest FEM-based method meeting our criteri...
متن کاملPhysIK: Physically Plausible and Intuitive Keyframing
We present an approach for animating characters using inverse kinematics (IK) handles that allows for intuitive keyframing of physically plausible motion. Specifically, we extend traditional IK and keyframing to include center-of-mass (CM) and inertia handles along with physically based templates to help an animator produce trajectories that respect physics during dynamic activities, such as sw...
متن کاملToward robust and physically plausible shaded stereoscopic segmentation
We address the multi-view shape from shading problem, that is the recovery of 3-D shape, lighting configuration and surface albedo from multiple calibrated views. Previous approaches to this problem relied on physically impossible illumination models (negative light), and resulted in biased estimates of shape and lighting positions. Furthermore, since the solution involves infinite-dimensional ...
