It's because the world matrices haven't been computed yet. 

Here I call scene.render() before your test:

Thx，The count1 should not equals 0,i think..cause the pickBox is from(0,0,0) to(9,9,9) ,and these two Mesh should intersect, several times 啊

yup.thx,and if i cycle 1000000 times,which i turned i,j,k into 100.....then i lost browser if i put scene.render() in the loop....)
