One of the earliest meshfree methods is smoothed particle hydrodynamics, presented in 1977. [1] Libersky et al. [2] were the first to apply SPH in solid mechanics. The main drawbacks of SPH are inaccurate results near boundaries and tension instability that was first investigated by Swegle.
A stronger form of the circle packing theorem asserts that any polyhedral graph and its dual graph can be represented by two circle packings, such that the two tangent circles representing a primal graph edge and the two tangent circles representing the dual of the same edge always have their tangencies at right angles to each other at the same ...
Vertex normals of a dodecahedral mesh. In the geometry of computer graphics, a vertex normal at a vertex of a polyhedron is a directional vector associated with a vertex, intended as a replacement to the true geometric normal of the surface. Commonly, it is computed as the normalized average of the surface normals of the faces that contain that ...
The sine and tangent small-angle approximations are used in relation to the double-slit experiment or a diffraction grating to develop simplified equations like the following, where y is the distance of a fringe from the center of maximum light intensity, m is the order of the fringe, D is the distance between the slits and projection screen ...
A free-form geometry statement can be specified in a line starting with the string vp. Define points in parameter space of a curve or surface. Define points in parameter space of a curve or surface. u only is required for curve points, u and v for surface points and control points of non-rational trimming curves, and u , v and w (weight) for ...
If it seems like you and everyone around you is getting sick this winter, you're not wrong. Experts say this is the worst flu season in the U.S. in more than a decade and cases are still trending ...
A texture map (left). The corresponding normal map in tangent space (center). The normal map applied to a sphere in object space (right). Normal map reuse is made possible by encoding maps in tangent space. The tangent space is a vector space, which is tangent to the model's surface. The coordinate system varies smoothly (based on the ...
