ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an image processing device, image processing method, a program distribution medium, and a data distribution medium more specifically, this invention relates to an image processing device and image processing method, a program distribution medium, and a data distribution medium, by which, for example, an image of detailed shape can be generated from rough shapes.
2. Description of the Prior Art
The higher degree of integration and higher speeds achieved in processors and memories have made possible what was previously difficult, namely the generation of three-dimensional images in real time, making it possible to display three-dimensional images (three-dimensional graphics) with a sense of presence for example on video game machines. If a three-dimensional image is to be displayed, in many cases the three-dimensional image is broken up into multiple polygons (unit graphic forms), and the three-dimensional image as a whole is drawn by drawing, each of these polygons. Thus it can be said that a three-dimensional image that is drawn in this way is defined as a combination of polygons.
Three-dimensional images are produced by composing three-dimensional shapes with, for example, wire frames. However, to compose a wire frame the producer must set detailed parameters concerning three-dimensional shapes, which has been troublesome. That is, as a three-dimensional shape becomes more complex, the wire frame parameters must also be set in detail, which has been troublesome.
SUMMARY OF THE INVENTION
It is an object of the present invention to make it possible to generate an image of detailed shape from rough shapes.
To attain the above and other objects the image processing device of the present invention comprises an interpolated line computation means for determining an interpolated line that is the line which interpolates between two vertices from the interpolation vector and vertex coordinates used for determining the line that interpolates a space between a given point and another point in the vertices of a unit graphic form, and an interpolated point computation means for determining, as the vertices of sub-unit graphic forms, interpolated points which are points on the interpolated line.
An image processing method of the present invention comprises an interpolated line computation step of determining the interpolated line which interpolates between two vertices from the coordinates of the vertices and an interpolation vector used for determining the line which interpolates between one vertex and another in the vertices of a unit graphic form, and an interpolated point computation step of determining, as the vertices of sub-unit graphic forms, interpolated points that are points on an interpolated line.
A program distribution medium of the present invention provides a computer program that has an interpolated line computation step that determines the interpolated line that interpolates between two vertices from the coordinates of the vertices and an interpolation vector used for determining the line that interpolates between one vertex and another in the vertices of a unit graphic form, and an interpolated point computation step that determines, as the vertices of sub-unit graphic forms, interpolated points that are points on an interpolated line.
According to an embodiment, an image processing device of the present invention comprises an operation means that is operated when a unit graphic form is input, and an interpolation vector generation means for generating an interpolation vector used for determining the interpolated line that is the line that interpolates between a given vertex and another vertex in the vertices of a unit graphic form that is input by the operation means being operated.
