01 / SEE THE INSTALLATION
Think in 3D.
See it in real time.
Move beyond a flat diagram. Explore the relationship between the projector, its beam and the projection surface inside a rendered 3D scene.
The visual result.
The technical decisions behind it.
THROXEL brings visual simulation and projection calculations into the same workflow. Bring in a live input, distribute the content across individual projectors and preview the projected result in real-time 3D. The installation optimiser considers lens-shift limits, projector orientation and physical occlusions from projector bodies, rigging frames and other scene elements. Assess how the installation occupies the space, how the image reaches the surface and how multiple projectors work together.

One room. Multiple projection surfaces.
A three-wall immersive room with a projected floor. Define the room dimensions and installation space, then calculate and adjust each face independently. Alignment grids and overlap bands show how the surfaces work together.
02 / PROJECTOR & LENS CATALOGUE
Real specifications.
Physical installation.
A projection system occupies real space. THROXEL connects the optical specification with the physical equipment, so the installation can be planned around the hardware that will actually go on site.
Equipment, model by model.
The catalogue brings together projector models, compatible lenses and manufacturer specifications. Projector dimensions and model-specific rigging-frame geometry give the optical calculation its physical context, wherever those profiles are available.
Optics in the real world.
Lens ratio, resolution, optical origin and lens-shift limits all matter to a projection design. Lens-distortion visualization is also part of the planned workflow, using clearly identified visual approximations where measured lens data is unavailable.
Plan the space around it.
Consider the complete equipment envelope, the lens position and the mounting frame alongside the projected image. The aim is to bring more real-world detail into the planning stage and reduce surprises during installation.

SEND / EXTERNAL PLATFORMS
Design in THROXEL.
Carry the setup forward.
Keep THROXEL as the reference for projector placement, surfaces and optics. Send workflows connect that design with the tools used to prepare the show. Keep a modern Disguise, PIXERA, WATCHOUT 7 or Resolume pipeline connected from planning to the production team.
Send to Disguise
Prepare projector tables, stage geometry and optical metadata for Designer. Position and target conversion has been checked with an asymmetric two-projector scene in Designer Starter r34.
Import the package, associate projectors with the screen, then check the physical lens and calibration. Materials, warp and blend masks are not transferred.
Send to PIXERA
Create screens and projectors in PIXERA 26.2 from your THROXEL installation, including curved screen geometry, projector positions, orientation, throw ratio and lens shift.
Check projector resolution, coverage and lens settings after sending. Media, physical lens profiles, warp and blend masks are not transferred.
Send to WATCHOUT 7
Choose Basic for the 3D scene and current projector placement, Basic + Warp for saved calibration and blending, or MPCDI for calibration files to import into WATCHOUT.
Assign physical outputs and verify alignment in WATCHOUT. Explore the three send modes →
SEND / WATCHOUT 7
THROXEL → WATCHOUT 7
Plan your projection setup.
Continue in WATCHOUT.
Prepare your installation in THROXEL and choose how to take it into WATCHOUT: send the 3D scene with current projector positions, include saved calibration and blending, or export MPCDI calibration files.
THROXEL / WATCHOUT 7
Scene transfer & calibration workflows
Send to WATCHOUT 7
Choose the transfer that fits your workflow.
Basic
Send the 3D scene, current projector positions and shared test patterns. Saved warp calibration and blending are not applied.
Basic + Warp
Send the 3D scene with saved warp calibration and blending, using native 3D projection. Recalculate the calibration in THROXEL if it is missing or outdated.
MPCDI
Export saved warp calibration and blending as MPCDI files for import into WATCHOUT. This is a file export workflow, rather than the native 3D project transfer.
Prepare your installation.
Review the scene, projector placement and shared test patterns in THROXEL. For Basic + Warp or MPCDI, make sure the saved calibration and blending match the installation you want to transfer.
Select a send mode.
Choose Send → Send to WATCHOUT 7, then select Basic, Basic + Warp or MPCDI. For the Basic modes, run WATCHOUT and its Asset Manager on the same computer to transfer the project assets.
Continue in WATCHOUT.
Basic / Basic + Warp: once the assets are ready, open the generated THROXEL.watch project in WATCHOUT 7.8.
MPCDI: import each Group_XX.mpcdi package and use its matching Group_XX_Overlap.png as the shared content canvas.
Assign outputs and check alignment.
Assign the projectors or imported MPCDI regions to your display nodes and physical outputs. Check orientation, coverage, overlap and alignment with the supplied patterns before adding show content.
Use one calibration workflow per output.
Basic + Warp and MPCDI are alternative ways to carry calibration into WATCHOUT. Do not apply both to the same outputs. Basic sends the current projector positions without applying saved warp or blending.
The current transfer supports curved-screen arrays. The example above illustrates a five-projector installation. Native transfer prepares a separate project; it does not replace the running show or start playback. Check final alignment on site. Colour and black-level calibration are not included.
Send the setup. Export the deliverables.
Send is dedicated to external platforms. Technical Export, Test Patterns, technical captures and presentation outputs remain in the Export workflow.
TECHNICAL EXPORT
Take the plan
to the production team.
Turn the proposed setup into documentation that can travel beyond the 3D workspace. Give technicians and clients a shared view of the installation.
Communicate the layout.
Export technical views showing projection surfaces, projector positions and projection geometry. Use PNG and PDF outputs to support installation planning and project discussions.
Keep the technical context.
Bring projector and lens information together with the distances, image dimensions, resolution and overlap data associated with the planned system.
Prepare for alignment.
Generate and export test patterns for individual projectors, with identification and blending references to support the installation workflow.
EXPORTED FROM THROXEL
A real installation sheet.
Two projectors. One curved screen. Explore the optical layout, physical dimensions and unwrapped blending canvas in an actual THROXEL technical export.
SCENES & REFERENCES
Start with the venue.
Build around the plan.
Connect the projection design to the space where it will be installed, using 3D geometry and the reference documents supplied by the production team after a site survey.
3D model import
Bring OBJ and FBX geometry into the scene, or import scenes from complete Unreal Engine projects through the compatible installed conversion bridge. Use the imported environment to place screens and projectors and preview your content.
Material and texture handling is an area of ongoing improvement.
Plans, CAD & Vectorworks workflows
Use images, PDF documents and CAD drawings as scaled references in plan and elevation. Align the venue drawing with the 3D scene and manage reference visibility and layers.
Import PNG/JPG, PDF and DXF references. For DWG, DWF and Vectorworks, export a supported interchange format from the originating application.
REFERENCE SCALE
Distance Calibration
Mark two points on a reference, enter the real distance between them and scale the reference to match. Use known dimensions to place screens, walls and projectors in context.
ENVIRONMENT & VIEWPORT QUALITY
Set the conditions.
Preview the installation.
Simulate the weather and lighting of the installation in a rendered 3D environment. Feed in your content and see how it appears across the projection surfaces in the scene.
Explore the scene conditions.
Use climate controls and lighting presets to simulate the conditions of the installation and preview your projected content in that environment.
Visual environment presets provide context. Photometric assessment still depends on the equipment, surfaces and measured ambient conditions.
Take the project to the venue.
THROXEL reads the available hardware to recommend an appropriate viewport quality profile. Use Laptop or Performance settings for practical on-site work, with manual control when you need it.
Visual quality settings adapt rendering workload; they do not change the underlying projection calculations.
Show the client the vision.
Back at the office, use a capable workstation and Cinematic quality to prepare richer views of the installation. Compose the scene and export captures for the client alongside the technical documentation.
Rendering performance depends on the hardware and the complexity of the scene.

BEFORE YOUR FIRST PROJECT
Trial, activation and on-site use.
What happens after the 7-day trial?
The trial needs no payment card and does not turn into a paid subscription. One trial is available per email and computer. To continue using THROXEL after it expires, choose a monthly or annual subscription. Your own content and project files remain yours; keep a backup before the trial ends.
How do I activate THROXEL?
Install THROXEL on your Windows computer and save the request file from the activation window. Import it at licenses.throxelsimulation.com, verify your email, then start the trial or choose a plan. Download the activation file and load it in THROXEL. Contact support if any step fails.
Why is the licence linked to my computer?
Activation authorises the email address and computer in your request file. The activation file is for that computer. If you replace your computer, contact support for help with activation on the replacement.
Can I use it offline at the venue?
Online licences allow up to 72 hours offline after successful verification, capped by your licence expiry. Verify online before load-in and plan an internet connection for longer installations. This is not an unlimited offline licence.
Is my projector and lens in the catalogue?
The catalogue contains model-specific projector and lens profiles, with dimensions and rigging geometry where available. Coverage varies by model. Before committing to a feasibility study, check your exact model and lens in the trial or ask support. Hardware visuals are reference representations, not certified manufacturer CAD.
Does THROXEL run on macOS?
The current download is for Windows 64-bit. A macOS release date is not published here. Contact support with your platform requirements before planning a project around a future version.
What information do I send for activation or support?
Activation uses a machine request file and a verified email address to authorise your computer. The support form collects the details you enter; messages are processed and stored using Cloudflare and delivered through Resend. Do not include confidential project files or sensitive personal information. Ask support about deletion or any project-data requirements before sharing files.
Does this replace on-site calibration or the media server?
THROXEL is for pre-production planning and preview. Send workflows support Disguise and PIXERA, and the Resolume plugin receives NDI preview video. Final physical lens checks, obstructions, rigging, warping and blending still need installation review. It is not a replacement for your show-control or calibration workflow.
