OpenGL在自己的轴上旋转3D多维数据集

[英]OpenGL rotate 3D Cube on own Axis

I have a 3D cube and I want to rotate it, but not using X,Y,Z Axis. 我有一个3D立方体,但我想旋转它,但不使用X,Y,Z轴。

I would like to rotate the cube on its own Axis. 我想在自己的轴上旋转立方体。

For example: I move my cube from right to left : my cube should rotate on bottom-left-axis of vertex about 90 Degree and not on Z-Axis about 90 Degree. 例如:我将多维数据集从右向左移动:我的多维数据集应该在顶点的左下轴上旋转大约90度,而不在Z轴上旋转大约90度。

I tried this : 我尝试了这个:

//prespektive...
gluPerspective(45,1.0,2.0,30.0);
//look at...
gluLookAt(0.0,2.0,  -4.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.0);
//try to rotate cube on bottom-right-axis
glTranslatef(-(-0.7), 0.40, -(-0.25));
glRotatef(90, 1,0,0);
glRotatef(90, 0,1,0);
glRotatef(90, 0,0,1);
glTranslatef(-0.7, 0.40, -0.25);

But it is not working. 但这是行不通的。 Any idea ? 任何想法 ?

Why did you spoil projection matrix. 你为什么破坏投影矩阵。 Before rotating the cube go to MODELVIEW matrix mode 旋转多维数据集之前,请转到MODELVIEW矩阵模式

// Setup the projection
glMatrixMode(GL_PROJECTION);
glLoadIdentity();

gluPerspective(45,1.0,1.0,30.0); // front clip plane to 1.0

// Now go to modelview
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

//look at...
gluLookAt(0.0,2.0,  -4.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.0);
//try to rotate cube on bottom-right-axis
glTranslatef(-(-0.7), 0.40, -(-0.25));
glRotatef(90, 1,0,0);
glRotatef(90, 0,1,0);
glRotatef(90, 0,0,1);
glTranslatef(-0.7, 0.40, -0.25);
