Question : What are the most common use cases for Meshroom VR ?

Answer : There are a great number of use cases. Each designer has its own points to be validated and its own creative process. Meshroom VR can be used during the internal validation with the design team during the design phase, or with external groups and even validation with the customer. The key thing about Meshroom VR is that because of its low cost, the speed to get it up and running and its simplicity, it is always on and can very easily be used. Designers, product managers will be able to make changes to the object and visualise it as many times as needed, with no extra costs. Discussions with differents services will be easier as distant people can receive the latest modifications by email and visualise them locally in VR, shortening decision cycle and reducing travel cost.

Question : What are the pre-requisite to be able to use Meshroom VR

Answer : Meshroom VR is a virtual reality visualisation solution running on a PC. It is using the commercially available HTC VIve helmet. This helmet is available in many computer stores. In order to use Meshroom VR, you thus need to own a compatible PC and an HTC Vive helment. WARNING : All PC are not VR compatible and in order to use smoothly Meshroom VR, there is a minimum level of requirements. Please check the Hardware compatibility page on Meshroomvr.com to check your HW compatibility.

Before starting to install Meshroomvr.exe file on your computer, you need to ensure that your HTC Vive helmet is correctly installed. There are detailled information within the HTC Vive box that will drive you through this process. This process includes the creation of a STEAM account.

Thereafter are a few screenshots of the HTC Vive installation process. Please refer to the HTC Vive documentation for more detailed information.

You are now ready to start using Meshroom VR Studio

Question : May I use Meshroom VR Studio on several computers ?

Answer : Meshroom VR Studio licence is linked to the physical characteristics of a single computer. It is thus attached to one computer only. It is not possible to use the same licence on several computers.

Question : Can I share my objets  once I textured them using Meshroom VR Studio ?

Answer : YES; Once you textured an object, you can save it in the first screen on the PC after leaving the VR showroom. Select the Save option and normally save the file as a .mro file. The MRO file format will save all the textures selected, it will also save the elevation levels saved in the VR elevator option and many other parameters. The MRO file can be transferred by email or other means to any person using Meshroom VR Studio application, who will be able to open the MRO file and visualise it textured , with all the saved parameters.

Question : What is Meshroom VR Studio "Texturing Mode"

Answer : Meshroom VR allows to apply textures to the different parts of an imported object in order to make the visualisation as realistic as possible.

This texturing is done directly in any of the VR showrooms by turning the "Texturing mode" ON.

Figure 1 : HTC Vive controller buttons

Pressing the button  "3) Switch to texturing mode" will alternately turn the texturing button ON and OFF.

In the texturing mode, there are three tables: the first one is showing the object to be textured and the balls representing all the different parts of the object that can be textured, the second on is a shelf with ready made textures and the third one is a texturing table enabling you to create any texture combination by changing colors and parameters.
