높이 크기가 다른 레이캐스팅
"창문의 미로"를 만들고 레이캐스팅 알고리즘을 사용하는 Java 프로젝트가 있습니다. 스크린샷은 다음과 같습니다.
보시다시피 모든 벽의 높이 크기는 동일합니다. 동일한 작업을 수행하고 싶지만 높이 크기가 다릅니다
private void CastRay(int xOnScreen,double angle,double Direction) {
R rx = castRayInX(angle,direction); R ry = castRayInY(angle,direction); // In case of out-of-space rays if (rx.getDistance()==Double.MAX_VALUE && ry.getDistance()==Double.MAX_VALUE) { graphics.setColor(BACKGROUND); graphics.drawLine(xOnScreen,0,xOnScreen,this.image.getHeight()); return; } double distance = rx.getDistance(); double normal = rx.getNormal(); Color c = rx.getColor(); double coef = Math.cos((angle+direction+Math.PI)-normal); Plot collision = rx.getPlot(); if (ry.getDistance()<rx.getDistance()) { distance = ry.getDistance(); normal = ry.getNormal(); c = ry.getColor(); coef = Math.cos((angle+direction+Math.PI)-normal); collision = ry.getPlot(); } coef = Math.abs(coef); int factor = map.length*SQUARE_SIZE; double d = (double)(distance+factor)/factor; coef *= 1/(d*d); Color c2 = new Color((int)(c.getRed()*coef),(int)(c.getGreen()*coef),(int)(c.getBlue()*coef)); graphics.setColor(c2);
// graphic.setColor(c); // 조명 없음
distance *= Math.cos(angle); // lens correction int h = (int)(this.screenDistance/distance*WALL_HEIGHT); // perspective height int vh = this.image.getHeight(); graphics.drawLine(xOnScreen,(vh-h)/2,xOnScreen,(vh+h)/2); drawEye(direction,collision);

내 Rclass에는 플롯(x, y, z)이 있습니다. 지금은 WALL_HEIGHT에 색상, 거리 및 법선을 사용합니다. 빛. 지금은 이것이 작동하지만 새로운 것을 추가하고 싶습니다
