Java 模型矩阵结果的Opengl转换

我试图建立一个模型矩阵，在这里我应用了一些常见的变换，比如缩放、旋转和平移。我在这里学习了一个教程：。我知道矩阵是不可交换的，所以我想我应该注意得到正确的变换顺序

但是当我尝试转换我的模型时，它会拉伸到相应的轴上，而不是转换。 下面是它的外观：

我将不胜感激

float aspectRatio = (float) HEIGHT /(float)WIDTH;

float[][] rotX = new float[][] {
        {1.0f,0.0f,0.0f,0.0f},
        {0.0f,(float)Math.cos(thetaX),(float)-Math.sin(thetaX),0.0f},
        {0.0f,(float)Math.sin(thetaX),(float)Math.cos(thetaX),0.0f},
        {0.0f,0.0f,0.0f,1.0f}

float[][] rotY = new float[][] {
        {(float)Math.cos(thetaY),0.0f,(float)Math.sin(thetaY),0.0f},
        {0.0f,1.0f,0.0f,0.0f},

        {(float)Math.cos(thetaZ),(float)-Math.sin(thetaZ),0.0f,0.0f},
        {(float)Math.sin(thetaZ),(float)Math.cos(thetaZ),0.0f,0.0f},

        {0.0f,0.0f,1.0f,transZ},
        {0.0f,0.0f,0.0f,1.0f}

float[][] scaleMatrix = new float[][] {
        {scale,0.0f,0.0f,0.0f},

float[][] rotationMatrix = Matrix.matMult(rotZ,Matrix.matMult(rotY,rotX));
float[][] matrix = Matrix.matMult(translation,Matrix.matMult(rotationMatrix,scaleMatrix));

float[] model = Matrix.matrixToFloatVector(Matrix.matMult(matrix,aspect));

FloatBuffer fb = BufferUtils.createFloatBuffer(16);
fb.put(model);

fb.flip();  // Reset pointer
// "upload" to graphics card
glUniformMatrix4fv(uLocMVP, false, fb);

见第110页：

要通过指定向量或标量来初始化矩阵，组件将按列主顺序分配给矩阵元素

mat4float，float，float，float，//第一列 float，float，float，float，//第二列 float，float，float，float，//第三列 浮动，浮动，浮动，浮动；//第四栏 这意味着您必须在设置mat4类型的统一变量之前转置矩阵

这可以通过设置第三个参数true自动完成：

glUniformMatrix4fvuLocMVP，真，fb

相反，您可以转置初始化并交换矩阵乘法matrix.matMult。

您必须转置矩阵。glUniformMatrix4fvuLocMVP，是的，fbYes确实有效，谢谢，如果你觉得可以，你可以向我解释为什么它在转置后有效吗？@rabbi76是因为opengl与列专业一起工作吗？
