Question

由于文件EXCEPTION_ACCESS_VIOLATION中的ig7icd64.dll，我的程序崩溃了。

我正在使用LWJGL库和在此处找到的一些外部jar创建一个简单的项目：https://github.com/CodingAP/LWJGL-3-Tutorial.git（仅使用slick-util3），并且从资源文件（'.png'）加载纹理时，程序崩溃。

我有很多使用大量GLXX.gl [function_name_here]的类，但我会解释为什么我不列出所有这些原因。

我用Window类创建一个窗口，该窗口只设置了GLFW上下文并可以正常工作。

我有一个Model类，它由UntexturedModel和TexturedModel扩展。这些将设置VertexArrays和VertexBuffers并正常运行。我什至有一个Shader类，可以读取两个着色器文件并正确应用它们。

public class UntexturedModel extends Model {

private int vertexArrayID, vertexBufferID, indicesBufferID, vertexCount;

public UntexturedModel(float[] vertices, int[] indices) {
    vertexArrayID = super.createVertexArray();
    indicesBufferID = super.bindIndicesBuffer(indices);
    vertexBufferID = super.storeData(0, 3, vertices);
    vertexCount = indices.length;
    GL30.glBindVertexArray(0);
}

public void destroy () {
    GL30.glDeleteVertexArrays(vertexArrayID);
    GL15.glDeleteBuffers(vertexBufferID);
    GL15.glDeleteBuffers(indicesBufferID);
}

// I have not included the getters for the IDs due to the space available
}

这扩展了下面的Model类：

public class Model {

protected int createVertexArray() {
    int vertexArrayID = GL30.glGenVertexArrays();
    GL30.glBindVertexArray(vertexArrayID);
    return vertexArrayID;
}

protected int storeData (int attributeNumber, int coordSize, float[] data) {

    FloatBuffer buffer = BufferUtils.createFloatBuffer(data.length);
    buffer.put(data);
    buffer.flip();

    int bufferID = GL15.glGenBuffers();
    GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, bufferID);
    GL15.glBufferData(GL15.GL_ARRAY_BUFFER, buffer, GL15.GL_STATIC_DRAW);

    GL20.glVertexAttribPointer(0, 3, GL11.GL_FLOAT, false, 0, 0);

    GL15.glBindBuffer(GL15.GL_ARRAY_BUFFER, 0);

    return bufferID;
}

protected int bindIndicesBuffer (int[] indices) {

    IntBuffer buffer = BufferUtils.createIntBuffer(indices.length);
    buffer.put(indices);
    buffer.flip();

    int bufferID = GL15.glGenBuffers();
    GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, bufferID);
    GL15.glBufferData(GL15.GL_ELEMENT_ARRAY_BUFFER, buffer, GL15.GL_STATIC_DRAW);
    GL15.glBindBuffer(GL15.GL_ELEMENT_ARRAY_BUFFER, 0);

    return bufferID;
}
}

TexturedModel本质上与UntexturedModel相同，但是具有一个额外的float [] textureCoords，它是使用storeData（1、2，textureCoords）添加的；它还具有使用外部罐子的Material属性：

public class Material {

private int textureID;

public Material (String file) {
    try {

        textureID = TextureLoader.getTexture("png", new FileInputStream("res/" + file)).getTextureID();
        // Possible error location: TextureLoader is an external jar

    } catch (IOException e) {
        System.err.println("Error: Couldn't load texture");
        System.exit(-1);
    }
}

public void destroy () {
    GL11.glDeleteTextures(textureID);
}
// I'm ignoring getters once again
}

即使对于着色器文件，使用UntexturedModel类也可以正常工作。我将在下面包括BasicShader和Shader类：

public abstract class Shader {

private int vertexShaderID, fragmentShaderID, programID;
private String vertexFile, fragmentFile;

public Shader (String vertexFile, String fragmentFile) {
    this.vertexFile = vertexFile;
    this.fragmentFile = fragmentFile;
}

public void create () {
    programID = GL20.glCreateProgram();

    vertexShaderID = GL20.glCreateShader(GL20.GL_VERTEX_SHADER);

    GL20.glShaderSource(vertexShaderID, readFile(vertexFile));
    GL20.glCompileShader(vertexShaderID);

    if (GL20.glGetShaderi(vertexShaderID, GL20.GL_COMPILE_STATUS) == GL11.GL_FALSE) {
        System.err.println("Error: Vertex Shader - " + GL20.glGetShaderInfoLog(vertexShaderID));
    }

    fragmentShaderID = GL20.glCreateShader(GL20.GL_FRAGMENT_SHADER);

    GL20.glShaderSource(fragmentShaderID, readFile(fragmentFile));
    GL20.glCompileShader(fragmentShaderID);

    if (GL20.glGetShaderi(fragmentShaderID, GL20.GL_COMPILE_STATUS) == GL11.GL_FALSE) {
        System.err.println("Error: Fragment Shader - " + GL20.glGetShaderInfoLog(fragmentShaderID));
    }

    GL20.glAttachShader(programID, vertexShaderID);
    GL20.glAttachShader(programID, fragmentShaderID);

    GL20.glLinkProgram(programID);

    if (GL20.glGetProgrami(programID, GL20.GL_LINK_STATUS) == GL11.GL_FALSE) {
        System.err.println("Error: Program Linking - " + GL20.glGetShaderInfoLog(programID));
    }

    GL20.glValidateProgram(programID);

    if (GL20.glGetProgrami(programID, GL20.GL_VALIDATE_STATUS) == GL11.GL_FALSE) {
        System.err.println("Error: Program Validation - " + GL20.glGetShaderInfoLog(programID));
    }
}

public abstract void bindAllAttributes();

public void bindAttribute (int index, String location) {
    GL20.glBindAttribLocation(programID, index, location);
}

public void bind () {
    GL20.glUseProgram(programID);
}

public void destroy () {
    GL20.glDetachShader(programID, vertexShaderID);
    GL20.glDetachShader(programID, fragmentShaderID);

    GL20.glDeleteShader(vertexShaderID);
    GL20.glDeleteShader(fragmentShaderID);

    GL20.glDeleteProgram(programID);
}

private String readFile (String path) {
    BufferedReader reader;
    StringBuilder builder = new StringBuilder();

    try {

        reader = new BufferedReader(new FileReader(path));

        String line = reader.readLine();

        while (line != null) {

            builder.append(line + '\n');
            line = reader.readLine();
        }

    } catch (IOException e) {
        System.err.println("Error: Exception while reading from file");
    }

    return builder.toString();
}
}

public class BasicShader extends Shader {

private static final String VERTEX_FILE = ".\\src\\shaders\\basicVertexShader.vs";
private static final String FRAGMENT_FILE = ".\\src\\shaders\\basicFragmentShader.fs";

public BasicShader() {
    super(VERTEX_FILE, FRAGMENT_FILE);
}

@Override
public void bindAllAttributes () {
    super.bindAttribute(0, "position");
    super.bindAttribute(1, "textCoords");
}
}

我已经测试了着色器文件（basicVertexShader.vs和basicFragmentShader.fs），它们可以按预期工作。

我尝试了以下方法：查看.dll文件是否已删除。重新安装Java（包括jdk和jre）重新安装Eclipse 英特尔建议的版本将Graohics驱动程序更新为

更新：我解决了这个问题。它位于Model.storeData（）中。我不使用attributeNumber或coordSize。关闭

Answer 1

[关闭]正如您在上次编辑中看到的那样，我的错误出在Model类中。我实际上并没有在index函数中使用size和storeData()参数，这意味着我试图将数组存储在同一列表中，因此程序崩溃了。谢谢大家。
