Making an attempt to get began with AWS IoT TwinMaker and have to convert your OBJ file to glTF? Maybe you could have carried out a degree cloud scan of your atmosphere with Matterport and it’s not clear how one can import the Matterpak bundle into AWS IoT TwinMaker. On this weblog, you’ll apply a mannequin conversion pipeline to compress and convert a Matterpak bundle into glTF format. This method will present updated 3D fashions and improved scene load occasions in AWS IoT TwinMaker.
On this weblog publish, a number of file extensions and mannequin codecs are referenced. Earlier than getting began, it’s good to grasp the next:
AWS IoT TwinMaker helps 3D belongings within the glTF format, which is a 3D file format that shops 3D mannequin data in JSON format or binary and permits environment friendly transmission and loading of 3D fashions in purposes. The glTF format minimizes the scale of 3D belongings and the runtime processing wanted to unpack and use them. The 3D fashions from conventional CAD purposes, in addition to level cloud scans, might be transformed to glTF utilizing AWS Associate options, reminiscent of these from Pixyz. On this weblog, you’ll discover an alternate server-less method to mannequin conversion of Matterpak bundles to glTF utilizing open supply libraries reminiscent of Cesium obj2gltf.
Within the structure beneath, you will notice how AWS Lambda can be utilized to detect a Matterpak zip bundle uploaded to an Amazon S3 bucket. This can set off the conversion to glTF inside an extended working Lambda execution. The zipped file could comprise OBJ, MTL, and JPG recordsdata.
Inside a Matterpak bundle, there are a number of recordsdata together with an OBJ, MTL, level cloud scan (xyz), and probably many JPG recordsdata. Matterport on this instance has transformed the purpose cloud scan to an object mesh format, OBJ. The MTL and JPG recordsdata collectively offers coloured texturing over the objects throughout the OBJ mannequin. The xyz file won’t be used on this conversion course of as this has already been transformed to OBJ within the Matterpak.
When working with level cloud scans reminiscent of Matterport, excessive decision JPG textures are captured all through the scan. Doing a easy conversion of the OBJ to glTF will nonetheless be fairly massive. To enhance this, the Lambda perform on this weblog will first compress all JPG photos previous to changing to glTF. In consequence, the conversion will produce a a lot smaller GLB or glTF file as seen on this AWS IoT TwinMaker Scene beneath. Be aware, a glTF file makes use of one in every of two attainable file extensions: .gltf or .glb. GLB will probably be used on this weblog as this can be a binary format versus JSON leading to a smaller mannequin file.
An AWS account will probably be required to setup and execute the steps on this weblog. An AWS Cloudformation template will configure and set up the required AWS Lambda Operate, IAM roles, and Amazon S3 bucket. It is strongly recommended that you simply work within the Virginia area (us-east-1). You could incur value on among the following providers:
Obtain one of many Matterpak Bundles. Choose one of many bundles, reminiscent of Pro2. This accessible checklist of bundles could change. The approximate file dimension for the Pro2 pattern bundle is 178MB.
To recap, you could have efficiently compressed and transformed a virtually 180MB level cloud scan by Matterport to a 18MB GLB file. With the mannequin transformed, you may attempt to load this in your IoT TwinMaker workspace. Be aware that any Mattertags you could have created in Matterport should not transferrable on this course of. This have to be recreated utilizing IoT TwinMaker Tags within the Scene composer.
Remember to clear up the work on this weblog to keep away from expenses. Delete the next assets when completed on this order
On this weblog, you created a mannequin conversion pipeline to compress and convert a Matterpak bundle into glTF format. This consists of generic conversion of OBJ from different methods as nicely. With this pipeline, it is possible for you to to cut back Scene load occasions and streamline 3D mannequin updates on to your IoT TwinMaker workspace.
Listed below are different mannequin conversion blogs accessible, with extra to return:
