我正在尝试围绕其中心（0、0、0）旋转一个三角形，然后将其平移（0.5、0.5、0）。但是，无论我将translateM命令放在rotateM命令之前还是之后，我仍然得到相同的结果，这是一个平移到所述位置的三角形，围绕 (0, 0, 0) 旋转（如果您愿意，可以绕行）。我在网上找了类似的帖子，但它们没有帮助。这是我的代码：

注意：我的三角形都以 (0, 0, 0) 为中心。

    Matrix.setIdentityM(mModelMatrix, 0);

    // *** transform shape before rendering

    Matrix.setRotateM(mRotationMatrix, 0, rx, -1.0f, 0, 0);
    Matrix.multiplyMM(mModelMatrix, 0, mRotationMatrix, 0, mModelMatrix, 0);        // rotate

    Matrix.setRotateM(mRotationMatrix, 0, ry, 0, -1.0f, 0);
    Matrix.multiplyMM(mModelMatrix, 0, mRotationMatrix, 0, mModelMatrix, 0);        // rotate

    Matrix.setRotateM(mRotationMatrix, 0, rz, 0, 0, -1.0f);
    Matrix.multiplyMM(mModelMatrix, 0, mRotationMatrix, 0, mModelMatrix, 0);        // rotate

    Matrix.translateM(mModelMatrix, 0, tx, ty, tz);                         // translate

    Matrix.multiplyMM(mvpMatrix, 0, mModelMatrix, 0, mvpMatrix, 0);         // world view


    // *** render

    // Add program to OpenGL environment
    GLES20.glUseProgram(mProgram);

    // get handle to vertex shader's vPosition member
    mPositionHandle = GLES20.glGetAttribLocation(mProgram, "vPosition");

    // Enable a handle to the triangle vertices
    GLES20.glEnableVertexAttribArray(mPositionHandle);

    // Prepare the triangle coordinate data
    GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX,
                                 GLES20.GL_FLOAT, false,
                                 vertexStride, vertexBuffer);

    // get handle to fragment shader's vColor member
    mColorHandle = GLES20.glGetUniformLocation(mProgram, "vColor");

    // Set color for drawing the triangle
    GLES20.glUniform4fv(mColorHandle, 1, color, 0);

    // get handle to shape's transformation matrix
    mMVPMatrixHandle = GLES20.glGetUniformLocation(mProgram, "uMVPMatrix");
    MyGL20Renderer.checkGlError("glGetUniformLocation");

    // Apply the projection and view transformation
    GLES20.glUniformMatrix4fv(mMVPMatrixHandle, 1, false, mvpMatrix, 0);
    MyGL20Renderer.checkGlError("glUniformMatrix4fv");

    // Draw the triangle
    GLES20.glDrawArrays(GLES20.GL_TRIANGLES, 0, vertexCount);

    // Disable vertex array
    GLES20.glDisableVertexAttribArray(mPositionHandle);

任何建议，将不胜感激。
