In geometry, a bitangent to a curve C is a line L that touches C in two distinct points P and Q and that has the same direction as C at these points....

have no internal bitangents and two external bitangents (they cannot be separated, because they intersect, hence no internal bitangents). If the circles...

theory of algebraic plane curves, a general quartic plane curve has 28 bitangent lines, lines that are tangent to the curve in two places. These lines...

applications will want bitangent to match the transformed geometry (and associated UVs). So instead of enforcing the bitangent to be perpendicular to...

Simulation noise is a function that creates a divergence-free vector field. This signal can be used in artistic simulations for the purposes of increasing...

calculating lighting coefficients such as the vertex's normal, tangent, and bitangent vectors. When a group of vertices (normally 3, to form a triangle) come...

The bitangents of a system of polygons or curves are lines that touch two of them without penetrating them at their points of contact. The bitangents of...

three bitangents that are not angle bisectors as x, y, and z, where x is the bitangent to the two circles that do not touch side a, y is the bitangent to...

\over dt}} is the unit tangent vector at each point. Then there will be a bitangent circle with center c and radius r if ( c − γ ( s ) ) ⋅ T _ ( s ) = ( c...
