我正在使用lwjgl在 Java 中構建 OPENGL 應用程序，并遵循thebennybox在 YouTube 上的部分教程我能夠使用我構建的 Mesh 類創建矩形。import engine.core.Util;import static org.lwjgl.opengl.GL15.*;import static org.lwjgl.opengl.GL20.*;public class Mesh {    private int vbo;    private int size;    public Mesh() {       this.vbo = glGenBuffers();       this.size = 0;    }    public void addVertices(Vertex[] vertices){        this.size = vertices.length * Vertex.SIZE;        glBindBuffer(GL_ARRAY_BUFFER, vbo);        glBufferData(GL_ARRAY_BUFFER, Util.createFlippedBuffer(vertices), GL_STATIC_DRAW);    }    public void draw(){        glEnableVertexAttribArray(0);        glBindBuffer(GL_ARRAY_BUFFER, vbo);        glVertexAttribPointer(0, 3, GL_FLOAT, false, Vertex.SIZE * 4, 0);        glDrawArrays(GL_TRIANGLES, 0, this.size);        glDisableVertexAttribArray(0);    }}和util幫手import engine.render.Vertex;import org.lwjgl.BufferUtils;import java.nio.FloatBuffer;public class Util {    public static FloatBuffer createFloatBuffer(int size){        return BufferUtils.createFloatBuffer(size);    }    public static FloatBuffer createFlippedBuffer(Vertex[] vertices){        FloatBuffer buffer = createFloatBuffer(vertices.length * Vertex.SIZE);        for(int i = 0; i < vertices.length; i++) {            buffer.put(vertices[i].getPos().getX());            buffer.put(vertices[i].getPos().getY());            buffer.put(vertices[i].getPos().getZ());        }        buffer.flip();        return buffer;    }}這是我渲染的方式  this.mesh = new Mesh();   Vertex[] data = new Vertex[]{           //1st triangle           new Vertex(new Vector3(0.5f,-0.5f,0)), //RB           new Vertex(new Vector3(-0.5f,-0.5f,0)), //LB           new Vertex(new Vector3(0.5f,0.5f,0)), //RT           //2nd triangle           new Vertex(new Vector3(-0.5f,0.5f,0)), //RB           new Vertex(new Vector3(0.5f,0.5f,0)), //RT           new Vertex(new Vector3(-0.5f,-0.5f,0)), //LB   };   mesh.addVertices(data);   public void render(){ //update per frame     mesh.draw();   }
