The assembly is modeled as rigid links connected by joints that are defined as mates, or geometric constraints. Movement of one element requires the computation of the joint angles for the other elements to maintain the joint constraints. For example, inverse kinematics allows an artist to move the hand of a 3D human model to a desired position ...
It is one of the well-known "Gang of Four" design patterns, which describe how to solve recurring problems in object-oriented software. [1] The pattern is useful when exactly one object is needed to coordinate actions across a system. More specifically, the singleton pattern allows classes to: [2] Ensure they only have one instance
Joint constraints are rotational constraints on the joints of an artificial system. [1] They are used in an inverse kinematics chain, in fields including 3D animation or robotics. [2] Joint constraints can be implemented in a number of ways, but the most common method is to limit rotation about the X, Y and Z axis independently. An elbow, for ...
Roblox (2006) offers a chance for everyone to create their own game by using the Roblox Lua programming language. It allows adding effects, setting up functions, testing games, etc. [ 1 ] Fortnite (2017) has game modes which allow players to either fight one another, fight off monsters, create their own battle arenas, race their friends, or jam ...
This is a topological constraint – there is no covering map from the 3-torus to the 3-dimensional real projective space; the only (non-trivial) covering map is from the 3-sphere, as in the use of quaternions.
where G is an instance of the label cover problem with unique constraints. The unique games conjecture states that for every sufficiently small pair of constants ε, δ > 0, there exists a constant k such that the (1 − δ, ε)-gap label-cover problem with unique constraints over alphabet of size k is NP-hard.
iClone is a real-time 3D animation and rendering software program. Real-time playback is enabled by using a 3D videogame engine for instant on-screen rendering. [1]Other functionality includes: full facial and skeletal animation of human and animal figures; lip-syncing; [2] import of standard 3D file types including FBX; a timeline for editing and merging motions; a Python API and a scripting ...
Tanner proved the following bounds Let be the rate of the resulting linear code, let the degree of the digit nodes be and the degree of the subcode nodes be .If each subcode node is associated with a linear code (n,k) with rate r = k/n, then the rate of the code is bounded by
