1. Orthogonal projection coordinate system 만들기 ¶
public void onSurfaceChanged(GL10 gl, int width, int height) { this.m_width = width; this.m_height = height; if(buffer == null) { Util.LOGD("make framebuffer"); world = new World(); m_cam = world.getCamera(); // light mass world.setAmbientLight(0xff, 0xff, 0xff); // making background plane float[] coordinates = { // position of vertices 0.0f, 0.0f, 0.0f, m_width, 0.0f, 0.0f, 0.0f, m_height, 0.0f, m_width, m_height, 0.0f }; float[] uvs = { // how uv mapped? 0.0f, 0.0f, 1.0f, 0.0f, 0.0f, 1.0f, 1.0f, 1.0f }; int[] indices = { // index of each coordinate 0, 2, 1, 1, 2, 3 }; // make plane Object3D plane = new Object3D(coordinates, uvs, indices, RMObject2D.getTextureIDByColor(Color.white)); plane.build(); Util.LOGD("center: " + plane.getTransformedCenter()); world.addObject(plane); // FOV settings m_cam.setFOVLimits(0.1f, 2.0f); m_cam.setFOV(0.1f); // set up camera // z = (width/2) / tan(fov/2) m_cam.setPosition(m_width/2, m_height/2, (float) -(m_width/2/Math.tan(m_cam.getFOV()/2.0f))); m_cam.lookAt(plane.getTransformedCenter()); fixCubePosition(); // configuration to view far object Config.farPlane = Math.abs(m_cam.getPosition().z) + 1000f; } // make framebuffer if(buffer != null) buffer.dispose(); buffer = new FrameBuffer(m_width, m_height, FrameBuffer.SAMPLINGMODE_NORMAL); }
2. FillBox class ¶
package cau.rpg.maker.object; import java.awt.Color; import javax.vecmath.Vector2f; import com.threed.jpct.Object3D; public class RMFillBox extends RMObject2D { public RMFillBox(float x1, float y1, float x2, float y2, Color color) { init(x1, y1, x2, y2, color); } public RMFillBox(Vector2f vStart, Vector2f vEnd, Color color) { init(vStart.x, vStart.y, vEnd.x, vEnd.y, color); } private void init(float x1, float y1, float x2, float y2, Color color) { if(x1 >= x2 || y1 >= y2) return; float z = -10f; float[] coords = { x1, y1, z, // up left x1, y2, z, // bottom left x2, y1, z, // up right x2, y2, z // bottom right corner }; float[] uvs = { 0f, 0f, 0f, 1f, 1f, 0f, 1f, 1f }; int[] indices = { 0, 1, 2, 2, 1, 3 }; m_polygon = new Object3D(coords, uvs, indices, getTextureIDByColor(color)); } }
3. 2D line class ¶
package cau.rpg.maker.object; import java.awt.Color; import javax.vecmath.Vector2f; import javax.vecmath.Vector3f; import com.threed.jpct.Object3D; public class RMLine extends RMObject2D { private static final Vector3f vectorZ = new Vector3f(0, 0, -1); public RMLine(Vector2f vStart, Vector2f vEnd, float width, Color color) { float z = -10f; Vector3f v3Start = new Vector3f(vStart.x, vStart.y, z); Vector3f v3End = new Vector3f(vEnd.x, vEnd.y, z); // line vector Vector3f lineVector = new Vector3f(); lineVector.sub(v3End, v3Start); // calc normal vector of line Vector3f normal = new Vector3f(); normal.cross(lineVector, vectorZ); normal.normalize(); normal.scale(width/2.0f); float[] coords = { (vStart.x + normal.x), (vStart.y + normal.y), z, (vStart.x - normal.x), (vStart.y - normal.y), z, (vEnd.x + normal.x), (vEnd.y + normal.y), z, (vEnd.x - normal.x), (vEnd.y - normal.y), z }; float[] uvs = { 0f, 0f, 0f, 1f, 1f, 0f, 1f, 1f }; int[] indices = { 0, 2, 1, 1, 2, 3 }; m_polygon = new Object3D(coords, uvs, indices, getTextureIDByColor(color)); } }
4. Interpolation ¶
public void setDepth(float depth) { float delta = depth - this.depth; // move object SimpleVector curPosition = m_polygon.getTransformedCenter(); SimpleVector toCam = MainRenderer.getCamera().getPosition().calcSub(curPosition); float a = MainRenderer.getCamera().getPosition().z - this.depth; toCam.scalarMul(delta/a); m_polygon.translate(toCam); Util.LOGD("translate to " + toCam); // scale m_polygon.scale((a-delta)/a); this.depth = depth; }
6. Actors.rvdata Parser: advanced(위 parser 코드와 이어짐) ¶
public void parse2(InputStream is) throws IOException { is.skip(3); int numChar = is.read()-6; Util.LOGD("캐릭터 수: " + numChar); int data; byte[] buf; while((data = is.read()) != -1) { // RPG::Actor(시그니쳐) 찾은 경우 if(finder_actor[0].addChar((byte) data)) { // 입력받을 클래스 변수 수 int numArgs = get_int(is.read()); // 변수 순서가 저장될 행렬 String result = null; List<String> argList = new ArrayList<String>(); // 첫번째 캐릭터 for(int i=0; i<numArgs; i++) { for(;is.read() != 0x3a;); // 다음 구분자까지 읽는다 // 이름 길이 int elementNameLen = get_int(is.read()); buf = new byte[elementNameLen]; // 변수 이름 입력 is.read(buf); result = new String(buf); // 변수에 들일 값 읽기 String value = getValue(is); Util.LOGD("발견!" + result + " value: " + value); argList.add(result); // 테이블은 있으면 개수에 포함하지 않는다 if(value.equals("u")) i--; } // 그 이후 캐릭터들 for(int i=0; i<numChar-1; i++) { Util.LOGD((i+2) + "번째 캐릭터 시작"); for(;is.read() != 0x3b;); // 시작 시그니쳐 건너뜀 for(int j=0; j<numArgs; j++) { for(;is.read() != 0x3b;); // 다음 구분자까지 // 변수 순서 int index = get_int(is.read()); String value = getValue(is); // 변수값 읽기 Util.LOGD("발견!" + argList.get(index-1) + " value: " + value); // 테이블은 있으면 개수에 포함하지 않는다 if(value.equals("u")) j--; } } } } } private String getValue(InputStream is) throws IOException { byte type = (byte) is.read(); String result = null; switch(type) { case 0x02: // table result = "table start"; read_table(is); break; case '"': //str int len = get_int(is.read()); if(len < 0) len = readShort(is); byte[] str = new byte[len]; is.read(str); result = new String(str); break; case 'i': // int int value = get_int(is.read()); result = String.valueOf(value); break; case 'T': case 'F': result = String.valueOf(type == 'T'); break; case 'u': result = "u"; } return result; }
