The Continuous Wavelet Transform on Conic Sections
Received (Day Month Year) Revised (Day Month Year) Communicated by (xxxxxxxxxx) We review the coherent state or group-theoretical construction of the continuous wavelet transform (CWT) on the two-sphere. Next we describe the construction of a CWT on the upper sheet of a two-sheeted hyperboloid, emphasizing the similarities between the two cases.. Finally we give some indications on the CWT on a...

متن کاملOn Rational Geometry of Conic Sections
Simple geometric objects and transformations appear in representations and algorithms of geometric facilities in computer applications such as modelling, robotics, or graphics. Usually, these applications only support objects and transformations fully describable by rational parameters, and a computer display of points of the objects at least implicitly requires points with rational coordinates...
متن کاملDrawing Lines and Conic Sections using Method of Deviation
Method of deviation was introduced in [1] for drawing implicit curves. This paper develops algorithms for drawing lines and conic sections using method of deviation. All computations are performed in integer mode. The lines and conic sections drawn are compared with those drawn using mid point algorithm.
متن کاملVirtual Models of Conic Sections
People know and use conic sections for a long time. They observe these curves in many situations: the parabolic trajectory of a thrown stone, the circular waves when the stone falls in calm water, and the elliptical shadows of round objects during sunsets (see Fig. 1). Conic sections were and still are one of the most favorite objects of mathematical study and education. Students spend hours in...
