3DTA是录像机所提供的一个非常优秀的组建，它使得可以在另外一种视角中观看OTA的世界，也便是提供了一个角度没有被限制在63.5°的镜头。
3DTA是利用的OTA 网络封包实现的，也便其实在联机时也可以以 3DTA做一个观战者的。虽然实际情况可能不是那样 /:^]
使用3DTA需要经过几个准备：
1.安装好OTA，标准的TA，可以直接从 http://www.mystoragelocker.net/ta/TOTALA_AllInOne.zip 下载,注意其中的 3.1补丁在安装时需手动设置安装目录。
2.安装录像机，注意选中3dreplayer
[list=1][]Type .3dta in the battleroom when you are about to start watching a recorded game. (This also works if you are a watcher in a regular game)[]When you want to switch to a 3D view, alt-tab out of TA and start the 3D Replayer. You do this by selecting 3D Replayer from the Start Menu → TA Demo.[*]You can quit the 3D Replayer at any time and alt-tab back to regular TA if you want to.[/list]
The list of keys and mouse stuff to control the 3D Replayer are as follows:
View control:
[list][]Right mouse button toggles mouse look.[]Moving the mouse while keeping the right mouse button pressed moves the camera view around.[]Clicking with the left mouse button rotates the camera to the pressed area.[]The mouse wheel moves the camera forward and backward.[]The arrow keys moves the camera.[]Keeping shift or ctrl pressed while moving alters the moving speed.[/list]Minimap control:
[list][]Left click in the lower right of the minimap to resize it.[]Left click anywhere else to move it.[]Right click to move the camera to the clicked position.[/list]Misc controls:
[list][]ESC - Exits the 3D Replayer.[]Enter - Sends a text line to TA.[]M - Toggles the minimap.[]H - Toggles healthbar above units.[]K - Toggles kill count for units.[]N - Toggles names above commanders.[]R - Toggles drawing of resources in the upper right of the screen.[]Pause - Pauses TA.[]Num +/- - Changes TA speed.[/list]
The 3D replayer only loads unit textures when it is first started. Therefore, to see any new textures that has been detected during a replay you MUST RESTART the 3D replayer.
If you get odd texture errors on explosions or similar you should first try to delete the files tatex.bmp and tatex.bin from the TA Demo directory.
On old operating systems (Windows 9x) performance may be bad. This is due to kernel limitations and not something we can do anything about.
