matrix - 沿一个坐标轴的3D偏斜变换矩阵

Question

有一种方法可以在给定倾斜角的情况下沿一个坐标轴计算倾斜变换矩阵，如下所示

Answer 1

这应该在大多数情况下可以使对象具有转换矩阵，特别是使用glMultMatrix(matrix)

matrix1[] = {
1,  0,  0,  0,
tan(a), 1,  0,  0,
0,  0,  1,  0,
0,  0,  0,  1
};

matrix2[] = {
    1,  0,  0,  0,
    0,  1,  0,  0,
    tan(a), 0,  1,  0,
    0,  0,  0,  1
};

matrix3[] = {
    1,  tan(a), 0,  0,
    0,  1,  0,  0,
    0,  0,  1,  0,
    0,  0,  0,  1
};

matrix4[] = {
    1,  0,  0,  0,
    0,  1,  0,  0,
    0,  tan(a), 1,  0,
    0,  0,  0,  1
};

matrix5[] = {
    1,  0,  tan(a), 0,
    0,  1,  0,  0,
    0,  0,  1,  0,
    0,  0,  0,  1
};

matrix6[] = {
    1,  0,  0,  0,
    0,  1,  tan(a), 0,
    0,  0,  1,  0,
    0,  0,  0,  1
};
