TopoGun 是一套重建表面 ( Resurfacing ) 與烘焙紋理貼圖 ( Maps baking ) 的軟體。
可以幫助你重新製作 3D 模型的布線，而模型細節不會遺失，因為重新拓撲的過程中製作的所有點線面都是吸附在你原有模型的表面上的。當你拓撲完成時，一個全新的由你控制布線結構的 3D 模型就誕生。3D模型拓撲功能在遊戲，影視項目中經常被用到。目前常用的3D模型軟體擁有這項模型拓撲功能的還有 TopoGun 是一套獨立的重建面，烘焙貼圖的軟體。他的重建多邊形功能可以幫助你 重新製作你 3D 模型的拓撲線，貼圖烘焙功能還可以將高模上的訊息烘焙成各種貼 圖，並應用於你重新製作的多邊形上。
Dedicated Topology Tools
Unlike any other 3D packages, TopoGun is a specialized standalone application, aimed for retopology in the first place. Each TopoGun tool is designed for topology creating and editing.
The newly created geometry wraps around the highres model in realtime. When you move the retopologized mesh components around, they will stick to the highres mesh's surface.
Friendly File Formats
TopoGun uses the .obj file format which is becoming more and more of a standard in today's 3D graphics. TopoGun's own file format is XML based and very easy to parse. Furthermore, TopoGun also supports the .ply file format (including per-vertex color information), used extensively in the 3D scanning industry.
TopoGun's baking and subdivision modules are fully multithreaded and up to 256 CPU cores are supported.
Multimillion 3D Meshes
TopoGun can handle extremely highres 3D data. The polycount limit is set by the available RAM on your system. It uses special rendering techniques to achieve unparalleled highres mesh rendering framerates.
One Pass Maps Baking
One great feature TopoGun has is one pass maps baking. Instead of baking one map at a time as most of the baking engines do, the types of maps you select are baked in a single pass, thus saving you precious time.
Hardware Ambient Occlusion
TopoGun uses the GPU (Graphics Processing Unit) for baking hardware ambient occlusion maps. The speed that GPU computing and multithreading offers is much greater than the ambient occlusion baking methods used by today's existing software.
TopoGun is a standalone application available for Windows, OS X, and Linux operating systems. TopoGun licenses are cross-platform and after buying one, TopoGun can be installed on any of these operating systems.
Native 32 and 64 Bit Executable
TopoGun is available in 32 and 64 bit executable code. The 64 bit version can access and use much more memory, thus increasing performance and capabilities.
In order to run and use TopoGun, you should have the following minimum system configuration:
- Microsoft ® Windows ® XP, Vista, Windows 7, Mac OS X 10.4, Linux CentOS 5.6, Fedora 14, openSUSE 11, Ubuntu 11 or later operating system;
- 1000 Mhz Intel ® Pentium ® III processor (or equivalent) or later;
- 512 MB RAM (2 GB recommended);
- 1024X768 32 bit display (1600X1200 recommended);
- 200 MB available disk space;
- Recent OpenGL ® 2.0 enabled graphics card (at least Nvidia ® GeForce ® 6600, or equivalent), with the latest drivers installed;
- A network adapter (it should provide a valid MAC address).
A SINGLE license allows you to run one instance of TopoGun at a time. The license is bound to one person and can only be active on an unique computer at a time. In order to move it to another computer, you should deactivate it on the computer it was previously installed and activate it on the other computer.
A SINGLE license can be activated Offline or Online.
Note that if you choose one activation method, you won't be able to switch to the other one.
If you want to move an Online activated license to another computer, you first need to return it to the server from here, before reactivating it on the new machine.
A FLOATING license allows you to run a limited number of TopoGun instances within an unique computer network (usually a LAN). You are not allowed to use the same license on more than one network. This kind of licensing model is useful for big studios, where there will be more than one person using TopoGun at the same time. Instead of buying a FLOATING license for each computer, you could buy several floating licenses for your network, usually less than the number of computers within the network.
FLOATING licenses are managed and installed on one computer within the network (the server). The server should have the TopoGun License Server or TopoGun License Service application installed, with at least one valid FLOATINGlicense.
In case your server runs on Windows operating system, TopoGun License Service is recommended over the TopoGun License Server.
