Abstract

본 발명은 원근 지형의 영상 재생 방법에 관한 것으로, 지형의 고도 데이타가 음양감을 갖게 하기 위해 지형의 밝기와 그림자를 넣는 단계(S1)와; 시각점이 평면상에 있다고 가정하고 시각의 진행 방향이 평행이 되도록 지형을 사다리꼴로 변형하는 단계(S2); 평행한 진행 방향을 가지는 시각을 따라 지형의 영상을 계산하는 단계(S3); 시각점을 원 시점으로 옮겨 지형의 영상을 원근 영상이 되게 보상하는 단계(S4) 및; 지형의 영상을 디스플레이하는 단계(S5)로 순차 동작하여, 원근 지형의 영상을 생성하므로 그 속도가 빠를 뿐만아니라 소프트웨어적으로 처리할 수 있는 것이다.The present invention relates to a method for reproducing an image of a perspective terrain, comprising: adding brightness and a shadow of the terrain so as to make the altitude data of the terrain sound; Assuming that the viewpoint is on a plane, transforming the terrain into a trapezoid such that the traveling direction of the vision is parallel (S2); Calculating an image of the terrain along a time point having parallel advancing directions (S3); Compensating an image of the terrain to be a perspective image by moving the viewpoint to the original viewpoint (S4); In step S5 of displaying an image of the terrain, the image of the terrain is generated in a sequential manner, not only because of its speed but also by software.
