For the geostationary model:
>> 1) can you make the equator plane more obvious?

> Ok done [img]http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=dlattach;topic=1877.0;attach=4266;image[/img] transparency = 200 instead of 50 previously

>> 3) For mode 7, can you make the satellite rotate at the same rate as Earth?
> Done already [img]http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=dlattach;topic=1877.0;attach=4272;image[/img]
>> 4) For mode 6, the axis of rotation for satelllite is wrong, even for non 3D
>> model. Can you correct it?
>>
> It is correct, I dont get why u say wrong.[img]http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=dlattach;topic=1877.0;attach=4274;image[/img]
