摘要： The invention relates to an educational measuring and numeration device with which at least one standard measuring unit is associated, said standard measuring unit defining a section on the device. Each section of the device corresponding to a standard measuring unit comprises at least one visual and/or tactile identification means, said means being continuously visible over the section itself, and the visual and/or tactile identification means of adjacent sections are distinct such that each section of the material can be identified in relation to the adjacent section(s).

摘要： Apparatus and method for producing a depth illusion of continuous three dimensional objects using the Moire effect is presented. The apparatus includes at least two surfaces separated by a small distance, one of which surfaces is a transparent sheet imprinted with vertical or nearly vertical, line patterns with slowly varying period in a horizontal direction, and the other is imprinted with a color or black and white horizontally almost periodic pattern related to the other surface pattern in such a way that the combination of both patterns produces a Moire pattern that creates a depth illusion in the observer's mind.

摘要： A three-dimensional observation device for observation of mathematical, physical and other figures, dimensions or properties, comprising several nesting ball shells (a, b, c...), which can be opened separately. Each ball shell (a, b, c...) is formed of six spherical caps (1) tangent to one another and of eight triangular ball surface sections (2), between caps (1) all of them independent parts while the thickness of the shell section formed by them is R - R∑2.

摘要： The principles of geometrical projection can be demonstrated with a drawing aid which preferably can be assembled from a kit of parts and which comprises an elongate base (10) carrying a number of object and image elements which can be set at different positions along the base and in different attitudes. These elements may comprise for example a sighting rod (19), a transparent sheet-form element (17) which defines a picture plane and on which the user draws images, an object (15), and a reflector (18). Perspective, orthographic and oblique projections can be demonstrated with just the one instrument using appropriate slots and holes to mount the elements.

摘要： Method for describing a thread as a geometric object in a three dimensional computer graphics system. The method comprises generating a set of fixture points defining points in space through which the thread passes, generating a set of one or more segments representing the thread between adjacent fixture points, linking each segment to a pair of fixture points, one at each end of the respective segment, and describing the geometrical properties of each segment. The segments and fixture points are preferably defined as objects containing functions and variables allowing the exchange of data between the various objects. The method allows for the calculation of the shape of the thread based on a calculation of the shape of each individual segment. A simulation system utilizing the method receives update information such as control signals, over an input interface and includes instructions on a storage media and a processor for calculating the shape of the thread and outputting the result over an output interface.
