Render a 3D Object off the Center of the screen: ARTOOLKIT ANDROID

由 那年仲夏 提交于 2019-12-11 17:20:09
问题 Hi I am working on a AR android app. I am using ARToolkit6. In this app I want to view my 3D object( A Cube) on left half of the screen. With this eventually I want to display 3 cubes on the screen each on 1/3 of the screen area. I was able to scale the 3D object by tweaking ModelView Matrix. What I read so far, I think I need to tweak projection matrix to achieve my goal. I tried looking solutions online. But Couldn't get it to work. Can anyone direct me to right path? for (int trackableUID

问题 I have problem about importing the FBX model. I have done it with Unity so I know the model exported well but I should do with the native code as well. I am getting error: 2015-06-02 15:20:21.721 ARAppNFTOSG[746:481003] Error: unsupported model file type (fbx). Ignoring. I am trying it on the AR example named ARAppNFTOSG.

Adding ARToolkit Marker tracking into Tango

由 核能气质少年 提交于 2019-12-07 08:20:31
I have been trying to integrate ARToolkit Marker Object tracking into a Tango Application . So far I have created a build so that a tango app can access and use the ARToolkit Native Library or the ARToolkit Unity wrappers. However, they both seem to require exclusive access to the camera in their default configurations. How could you feed the same Android video feed to both libraries? Could you create a dummy camera device which doubles out the feed? Could you take the tango feed as normal, and then resend it into ARToolkit with a special VideoConf [edit] ARToolkit uses the older Camera1 API,
