Abstract
A method and an apparatus for three dimensional display with cross section capable of displaying three dimensionally in real time, according to which a surface image in which the object is cut at the cutting plane and the cross section is left open is generated from the surface data and the cutting plane data, while at the same time a cross sectional image in which an interior region of the cross section is painted out in a prescribed color is generated from the surface data and the cutting plane data, and the surface image and the cross sectional image are displayed with the cross sectional image superposed on the surface image.
Claims8
An apparatus for three dimensionally displaying an object with a cross section, comprising:
- two dimensional surface data memory means for storing surface data representing a surface of said object in a form of a collection of two dimensional figures;
- two dimensional cutting plane buffer means for storing cutting plane data representing a cutting plane on which said cross section lies;
- surface image generating means for generating a surface image, in which said object is cut at said cutting plane and said cross section is left open, from said surface data and said cutting plane data;
- cross sectional image generating means for generating a cross sectional image, in which an interior region of said cross section is painted in a prescribed color, from said surface data and said cutting plane data, and where said cross sectional image generating means generates said cross sectional image during a generation of said surface image by said surface image generating means, in parallel to generation of said surface image by said surface image generating means;
- and
- display means for displaying said surface image and said cross sectional image by superposing said cross sectional image as generated by said cross sectional image generating means on said surface image as generated by said surface image generating means.
A method of three dimensional display of an object with a cross section, comprising the steps of:
- storing surface data representing a surface of said object in a form of a collection of two dimensional figures;
- storing two dimensional cutting plane data representing a cutting plane on which said cross section lies;
- generating a surface image, in which said object is cut at said cutting plane and said cross section is left open, from said surface data and said cutting plane data;
- generating a cross sectional image, in which an interior region of said cross section is painted in a prescribed color, from said surface data and said cutting plane data, wherein said cross sectional image is generated during a generation of said surface image at said surface image generating step, in parallel to generation of said surface image at said surface image generating step;
- and
- displaying said surface image and said cross sectional image by superposing said cross sectional image as generated at said cross sectional image generating step on said surface image as generated at said surface image generating step.
