我试图创建一个类来加速我的程序中纹理多边形的生产，但纹理不显示。OpenGL 3.2纹理不显示
我使用LWJGL和Slick2D进行纹理加载。
这是我TexturedPolygon类：
package zeus.core.geom;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.FloatBuffer;
import java.util.ArrayList;

import org.newdawn.slick.opengl.TextureLoader;
import zeus.core.Disposable;
public class TexturedPolygon extends Disposable {
private final List<Float> vertices = new ArrayList<Float>();
private final List<Float> texCoords = new ArrayList<Float>();
private final int VAO, VBO;
private final FloatBuffer vertBuffer;
private final ByteBuffer texBuffer;
private final int GL_DRAWING_MODE;
private final String IMG_FILE;
private final Texture TEXTURE;
public TexturedPolygon(final LinkedHashMap<Vector2f, Vector2f> info, final String IMG_FILE, final int GL_DRAWING_MODE) throws IOException {
this.IMG_FILE = IMG_FILE;
this.GL_DRAWING_MODE = GL_DRAWING_MODE;
this.TEXTURE = TextureLoader.getTexture(".png", new FileInputStream(new File(System.getProperty("user.dir") + "/res/img/", IMG_FILE)));
for(Map.Entry<Vector2f, Vector2f> entry : info.entrySet()) {
vertices.add(entry.getKey().x);
vertices.add(entry.getKey().y);
texCoords.add(entry.getValue().x);
texCoords.add(entry.getValue().y);
}
vertBuffer = BufferUtils.createFloatBuffer(vertices.size());
final float[] vertArray = new float[vertices.size()];
int i = 0;
for(final float f : vertices) {
vertArray[i++] = f;
}
vertBuffer.put(vertArray);
vertBuffer.flip();
VAO = GL30.glGenVertexArrays();
GL30.glBindVertexArray(VAO);
VBO = GL15.glGenBuffers();
GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, VBO);
GL15.glBufferData(GL15.GL_ARRAY_BUFFER, vertBuffer, GL15.GL_STATIC_DRAW);
GL20.glEnableVertexAttribArray(0);
GL20.glVertexAttribPointer(0, 2, GL11.GL_FLOAT, false, 0, 0);
GL30.glBindVertexArray(VAO);
GL11.glBindTexture(GL11.GL_TEXTURE_2D, TEXTURE.getTextureID());
texBuffer = BufferUtils.createByteBuffer(TEXTURE.getTextureData().length);
texBuffer.put(TEXTURE.getTextureData());
texBuffer.flip();
GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, TEXTURE.getTextureID());
GL15.glBufferData(GL15.GL_ARRAY_BUFFER, texBuffer, GL15.GL_STATIC_DRAW);
GL20.glVertexAttribPointer(1, 4, GL11.GL_FLOAT, false, 0, 0);
GL20.glEnableVertexAttribArray(1);
}
public void draw() {
GL30.glBindVertexArray(VAO);
GL11.glDrawArrays(GL_DRAWING_MODE, 0, vertices.size());
GL30.glBindVertexArray(0);
}
public void update(final int delta) {
}
@Override
public void dispose() {
GL20.glDisableVertexAttribArray(0);
GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0);
GL15.glDeleteBuffers(VBO);
GL30.glBindVertexArray(0);
GL30.glDeleteVertexArrays(VAO);
GL11.glBindTexture(GL11.GL_TEXTURE_2D, TEXTURE.getTextureID());
}
public int getVAO() {
return VAO;
}
public int getVBO() {
return VBO;
}
public int getDrawingMode() {
return GL_DRAWING_MODE;
}
public FloatBuffer getVertBuffer() {
return vertBuffer;
}
public ByteBuffer getTextureBuffer() {
return texBuffer;
}
public List<Float> getVertices() {
return vertices;
}
public List<Float> getTexCoords() {
return texCoords;
}
public String getImageFilename() {
return IMG_FILE;
}
}
这是我的主类：
package tests;
import java.util.LinkedHashMap;
import org.lwjgl.opengl.GL11;
import org.lwjgl.opengl.GL20;
import org.lwjgl.util.vector.Vector2f;
import zeus.core.Window;
import zeus.core.geom.TexturedPolygon;
import zeus.core.opengl.Shader;
import zeus.core.opengl.ShaderProgram;
public class WindowTest {
public static void main(String[] args) throws Exception {
final Window win = new Window(800, 600, "Window Test");
win.create();
Shader vertexShader = new Shader("drawing_test_vertex", GL20.GL_VERTEX_SHADER);
Shader fragmentShader = new Shader("drawing_test_fragment", GL20.GL_FRAGMENT_SHADER);
ShaderProgram program = new ShaderProgram();
vertexShader.compile();
fragmentShader.compile();
LinkedHashMap<Vector2f, Vector2f> info = new LinkedHashMap<Vector2f, Vector2f>();
info.put(new Vector2f(0f, 0f), new Vector2f(0f, 0f));
info.put(new Vector2f(1f, 0f), new Vector2f(1f, 0f));
info.put(new Vector2f(1f, 1f), new Vector2f(1f, 1f));
info.put(new Vector2f(1f, 1f), new Vector2f(1f, 1f));
info.put(new Vector2f(0f, 1f), new Vector2f(0f, 1f));
info.put(new Vector2f(0f, 0f), new Vector2f(0f, 0f));
TexturedPolygon p = new TexturedPolygon(info, "test.png", GL11.GL_TRIANGLES);
program.addShader(vertexShader);
program.addShader(fragmentShader);
program.link();
program.use();
while(!win.isCloseRequested()) {
win.clear();
p.update(1);
p.draw();
win.update(120);
}
p.dispose();
vertexShader.dispose();
fragmentShader.dispose();
program.dispose();
win.dispose();
}
}
而这些是我的着色器文件：
顶点：
#version 410
layout(location=0) vec3 pos;
layout(location=1) vec2 tex;
out smooth vec2 Tex;
void main() {
gl_Position = vec4(pos, 1.0f);
Tex = tex;
}
片段：
#version 410
layout(location=0) vec2 Tex;
uniform sampler2D textureDiffuse;
out vec4 color;
void main() {
color = texture(textureDiffuse, Tex);
}
我不知道什么是造成这个问题。
这就是当前显示： 
颜色改变这里当我改变1和4之间的“大小”的说法在这条线：
GL20.glVertexAttribPointer(1, 4, GL11.GL_FLOAT, false, 0, 0);
