Abstract
Abstract A video game apparatus includes an external ROM. This external ROM is previously memorized with player object data, basic shadow object data and light object data. A direction in which a shadow is thrown is determined according to the player object data and the light object data, to thereby determine a length of each leg of the player object. Based on the length of the leg and the height of the light, a length of the shadow is determined. Based on the height of each leg, a depth of the shadow is determined. A shape of a displaying shadow object is determined from a state of a ground object to which the shadow is thrown.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
80 words
A method of displaying a shadow image for a displayed object, comprising: generating basic shadow data for the displayed object, wherein the basic shadow data defines a basic shadow object having a circular form represented by two sets of polygons; generating deformed shadow data from the basic shadow data based on at least light position data and object data; and displaying the object and a deformed shadow for said object based on the object data and the deformed shadow data.
Claim 2
Independent Claim
80 words
A method of displaying a shadow image for a displayed object, comprising: generating basic shadow data for the displayed object, wherein the basic shadow data defines a basic shadow object having a circular form represented by two sets of polygons; generating deformed shadow data from the basic shadow data based on at least light position data and object data; and displaying the object and a deformed shadow for said object based on the object data and the deformed shadow data.
Claim 3
Dependent Claim
27 words
The method of claim 1 , further including displaying the deformed shadow based on ground object data defining a surface on which the deformed shadow is displayed.
Claim 4
Dependent Claim
20 words
The method of claim 1 , generating the deformed shadow data includes changing a transparency of the basic shadow object.
Claim 5
Independent Claim
123 words
A method of displaying a shadow image for a displayed object having a first leg and a second leg, comprising: generating first basic shadow data for the first leg of the object; generating second basic shadow data for the second leg of the object; generating first deformed shadow data for the first leg from the first basic shadow data based on at least light position data and object data; generating second deformed shadow data for the second leg from the second basic shadow data based on at least light position data and object data; and displaying the object, a first deformed shadow and a second deformed shadow based on the object data, the first deformed shadow data and the second deformed shadow data.
Claim 6
Independent Claim
123 words
A method of displaying a shadow image for a displayed object having a first leg and a second leg, comprising: generating first basic shadow data for the first leg of the object; generating second basic shadow data for the second leg of the object; generating first deformed shadow data for the first leg from the first basic shadow data based on at least light position data and object data; generating second deformed shadow data for the second leg from the second basic shadow data based on at least light position data and object data; and displaying the object, a first deformed shadow and a second deformed shadow based on the object data, the first deformed shadow data and the second deformed shadow data.
Claim 7
Dependent Claim
33 words
The method of claim 4 , further including defining the first and second basic shadow data so that they define basic shadow objects having a circular form represented by two sets of polygons.
Claim 8
Dependent Claim
51 words
The method of claim 4 , further including determining a length of the first and second legs based on a distance that each leg is located from a ground object, and determining a length of the first and second deformed shadows based at least in part on said leg lengths, respectively.
Claim 9
Independent Claim
95 words
A method of displaying a plurality of shadow images for a displayed object, comprising: generating basic shadow data for the displayed object, wherein the basic shadow data defines a basic shadow object having a circular form represented by two sets of polygons; generating a plurality of deformed shadow data sets from the basic shadow data based on object data and on a plurality of light position data sets, respectively; and displaying the object and a plurality of deformed shadows for said object based on the object data and the plurality of deformed shadow data sets.
Claim 10
Independent Claim
95 words
A method of displaying a plurality of shadow images for a displayed object, comprising: generating basic shadow data for the displayed object, wherein the basic shadow data defines a basic shadow object having a circular form represented by two sets of polygons; generating a plurality of deformed shadow data sets from the basic shadow data based on object data and on a plurality of light position data sets, respectively; and displaying the object and a plurality of deformed shadows for said object based on the object data and the plurality of deformed shadow data sets.
