Abstract
Abstract @ A system and method for altering an aspect of one of a plurality of coincident visual objects comprises means for generating first and second coincident visual objects, the first visual object having an alteration attribute thereof. Means are provided for identifying the alteration attribute of the first visual object in conjunction with means responsive to the identifying means for altering the aspect of the second visual object. In accordance with the system and method of the invention, the color of a true object overlapping a fixed object of lesser priority may be modified such that it appears that the true object has entered the shadow of the fixed object.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
66 words
A video display generator including a system for altering an aspect of one of a plurality of coincident visual objects comprising: means for generating first and second coincident visual objects, said first visual object having an alteration attribute thereof; means for identifying said alteration attribute of said first visual object; and means responsive to said identifying means for altering said aspect of said second visual object.
Claim 2
Dependent Claim
66 words
A video display generator including a system for altering an aspect of one of a plurality of coincident visual objects comprising: means for generating first and second coincident visual objects, said first visual object having an alteration attribute thereof; means for identifying said alteration attribute of said first visual object; and means responsive to said identifying means for altering said aspect of said second visual object.
Claim 3
Dependent Claim
16 words
The video display generator of claim 1 wherein said first visual object is a fixed object.
Claim 4
Dependent Claim
16 words
The video display generator of claim 1 wherein said second visual object is a true object.
Claim 5
Independent Claim
59 words
A method for altering an aspect of one of a plurality of coincident visual objects comprising the steps of: generating first and second coincident visual objects, said first visual object having an alteration attribute thereof; identifying said alteration attribute of said first visual object; and altering said aspect of said second visual object when said alteration attribute is identified.
Claim 6
Independent Claim
59 words
A method for altering an aspect of one of a plurality of coincident visual objects comprising the steps of: generating first and second coincident visual objects, said first visual object having an alteration attribute thereof; identifying said alteration attribute of said first visual object; and altering said aspect of said second visual object when said alteration attribute is identified.
Claim 7
Dependent Claim
18 words
The method of claim 4 wherein said step of identifying is carried out by means of a comparator.
Claim 8
Dependent Claim
22 words
The method of claim 4 wherein said step of altering further comprises the step of: changing an address to a CMR register.
Claim 9
Independent Claim
88 words
A system for altering an aspect of one of a plurality of coincident visual objects in a video display generator comprising: means for generating first and second visual objects, said first visual object having first and second data attributes thereof; means for comparing said first and second data attributes of said first visual object; and means responsive to said comparing means for altering said aspect of said second visual object when coincident with said first visual object and said first data attribute differs from said second data attribute.
Claim 10
Independent Claim
88 words
A system for altering an aspect of one of a plurality of coincident visual objects in a video display generator comprising: means for generating first and second visual objects, said first visual object having first and second data attributes thereof; means for comparing said first and second data attributes of said first visual object; and means responsive to said comparing means for altering said aspect of said second visual object when coincident with said first visual object and said first data attribute differs from said second data attribute.
Claim 11
Dependent Claim
14 words
The system of claim 7 wherein said first visual object is a fixed object.
Claim 12
Dependent Claim
14 words
The system of claim 7 wherein said second visual object is a true object.
Claim 13
Dependent Claim
20 words
The system of claim 7 wherein said first and second data attribute are pel value and color collision bits respectively.
