  1. Prisms in GDTG are part of the Wheel and in particular, they are inside of what is called a Wheel Slot. Prisms definitions in GDTF allow precise definition of each of the prism facet and it is done by using transformations represented by Rotation matrices. There are many resources on rotation matrixes, for example this Wikipedia article and also many game engine related tutorials and articles, like this one, which is useful for our 2D prism definitions. In the GDTF Builder, there is a really nice Prism editor which can do some of the math for you, like rotations and transformation (moveme
  2. ErrorCode67: "If two channel functions use the same DMX range, mode masters should be defined" 🙂 P.
  3. Hi guys, i listened to your discussion on Friday, certainly a good talk about GDTF, the name check was totally unexpected 🙂 , thank you 🙂 All credit here to the team, both in the GDTF group and also in Robe - to the guys collecting the data and punching it in 🙂 As for the few things i remember i wanted to comment on: - gobo rotation between fixtures/manufacturers - yes, GDTF is providing mapping between control and physical, so as long as you say what speed and direction you need and the data is present in the GDTF, the console has the ability to send out the required DMX
  4. A DMX Mode is a container holding definition of DMX channels and GDTF allows us to define multiple DMX modes for a single device withing one GDTF file. The concept of multiple DMX modes is good, because not only we can have a complete device definition in a single GDTF file, but we can also define DMX modes for different software version of the device. This allows us to provide both older and newer versions of DMX definitions if needed. For this to work in the GDTF Builder, we must first define RDM details on the Fixture tab: If you do not know the Manufacturer ID, it can be fo
  5. Hi @Livecue i think it is better to report directly in VW issue tracker or their forum... the will need to know what you are exporting the MVR from... cheers Petr
  6. Thank you @Janng for the report. I am glad to see Firefox and Ubuntu referenced 🙃 cc: @pedromagalhaes
  7. Rasterized PNG images are used in GDTF in several places - as a device thumbnail or as a MediaFileName in slots for gobo wheels and animation wheels. While the definition of a device thumbnail is quite simple (a png file to provide the rasterized picture with maximum resolution of picture 1024 x 1024), definition for a gobo slot image is more involved: Gobo images shall be in PNG format with an alpha channel. Indexed, Greyscale and Alpha, 8-bit RGB and Alpha, or 16-bit RGB and Alpha are accepted pixel formats. The Background shall be fully transparent and should be considered to be the eq
  8. 3D models are one of the essential assets in GDTF. Lets see what we need to do to make our 3D files ready for GDTF. You can either use generic 3D models already predefined by GDTF and available in the GDTF builder, or you can provide your models. Models can currently be provided in the form of 3DS files, or in the future it will be also possible to use glTF files. How to create models of the devices is out of scope of this post, what we will look at today is how to modify and adjust existing 3D models provided by the manufacturer for use in GDTF - apply position, rotation, alignment and
  9. Before you define any physical attributes, you have to make sure to understand how positioning, rotation and orientation is defined in GDTF. 3D space definition GDTF defines this this way: The metric system consists of the Right-handed Cartesian Coordinates XYZ: X – from left (-X) to right (+X), Y – from the outside of the monitor (-Y) to the inside of the monitor (+Y), Z – from bottom (-Z) to top (+Z). For a device, everything starts for you with your 3D model. Here is GDTF definition: The device shall be drawn in a hanging position displaying the front view. That re
  10. One of the advantages and ideas of GDTF is a central repository - GDTF Share, connected with a GDTF file editor - the GDTF Builder. Using the Share is pretty straight forward - you can upload, search and download files... but in reality there is much more going on behind the scenes. The Share contains powerful filtering and management system to ensure that this repository is kept nice and tidy, while at the same time any random person still can upload a GDTF creation of their own for others to use. Lets look at that... Searching and filtering Users can search the Share easily:
  11. First steps of getting into GDTF... let's get right into it. Accounts Create and account in https://gdtf-share.com/ so you can access the Share, Builder and the Forum. Sign into the forum at least once, so your account is activated here. If you are an industry related vendor (for example a manufacturer) drop an email to info@gdtf-share.com , together with brief introduction about who you represent and your Share username. This will provide you with the possibility to enable manufacturer account in the Share and invite to the monthly GDTF manufacturer's interfacing meeting and di
  12. >The specs really must permit files to be compressed with deflate. Thank you, we are open to suggestions and proposals. Btw, completely off topic in this thread ?
  13. You can add virtual pan/tilt to the geometry, which then allows the operator to preset these in places like MA3. For remotely connected visualizer (Vision...), virtual channels would not be transmitted, there you would have to do the adjustment by the tools of the visualizer (if available).
