In 3D or opengl mode can it be possible?(rotate with the line i set)still not slove!!!!

ATC243750496

for example rotate with this line: (0,0,300,300)

PhiLho

See the rotate() function.

The 2d Transformations tutorial is probably also relevant.

i said in 3D mode ..... i mean in 3D mode it only can rotate in X Y Z three direction can the rotate main axis be set by my self??? for examle set (0,0,300,300) as axis

hamoid

You mean like this?

size(600, 600, P3D);
float angle=1;
rotate(angle, 300, 300, 0);
rect(100, 100, 100, 100);

thanks,but what's 300,300,0?point?and that's mean the line across the (0,0,0) and (300,300,0)?

hamoid

Yes, you are defining an axis between 0,0,0 and 300, 300, 0, and then rotating around that axis.
