Abstract:
Modeling contact between two or more objects (such as a robotic arm placing a block on a stack of blocks) or articulations of a series of linked joints (such as modeling a backhoe) in a real-time computing application can introduce additional energy into the system or fail to resolve a constraint imposed on the system. Current techniques attempt to resolve these issues, for example, by using very small time steps. Very small time steps, however, can significantly increase computational costs of the modeling simulation. The introduced simulation techniques for rigid bodies use a time interval to reduce linearization artifacts due to the small time steps and reduce computational costs with faster solver convergence by permitting more efficient bias calculations. High mass handling can also be improved through the more efficient bias calculations.

Abstract:
Systems and methods are provided to perform constrained BSDF sampling in relation to various algorithms, and specifically in relation to ray tracing algorithms. In some embodiments, a method is provided to generate samples by: determining a spherical polygon on a unit hemisphere; determining, on a unit circle, a projected area corresponding to the spherical polygon on the unit hemisphere; determining a parameterization of the projected area of the spherical polygon on the unit circle; generating samples in the projected area based on the parameterization; and generating samples in the spherical polygon. The unit circle is abase of the unit hemisphere, and the projection of the projected area is along a vector perpendicular to the unit circle. The generated samples in the spherical polygon correspond to the samples in the projected area. The method may further include evaluating a rendering equation based on the generated samples in the spherical polygon.
