Introduction

MADRIX features 3 main Previews.
That means that you can have a look at your effects and visuals before they are displayed on your LED installation. These are live previews and they show everything in real time.

Preview Left
Preview Right
Preview Output
 
Preview Left / Preview Right - Located to the upper left and to the upper right of the user interface. They represent the two preview windows for the 2 Effect Pipelines. [Learn more »Work Areas [Left/Right]]
Preview Output - Is located in the middle. This window is a preview of the actual data output that is sent to your interfaces/LEDs.
 
A MADRIX Preview is a technical representation of your installation. You will see the individual pixels/voxels and how the effects will look on your LEDs, but not realistic renderings of your projects you may know from visualizers.
DVI output is explained at the end of this topic. Learn more DVI Output And External Previews

 

 

2D Or 3D Mode

As explained earlier, you can use MADRIX to control 2D and/or 3D projects. [Learn more »2D Or 3D [X, Y, Z]]
The 3 Previews support a 2D mode and a 3D mode to adequately represent your LED installation. In this way, they are an important part of your workflow when working with your project.

Go to Previews > Preview Left/Right/Output > 2D Mode to choose 2D mode for the left/right/middle Preview.

More Information

The Previews mainly show your effects and visuals. Depending on different settings and requirements they convey additional information. Note: The different scenarios explained below can apply at the same time.

 

Intensity

When controlling LED lighting, the intensity of the light output makes up a large factor of the light design. The Previews will represent your intensity settings.
There are many ways how to control the intensity in MADRIX. The main examples are:

Master, including Blackout

Master Set To 255

Master Set To 127

Master Set To 0 / Blackout

 

Rendering

One of the main features of MADRIX is that it renders visuals and effects live in real time. Regarding the overall performance, you can define a specific setting in the Options that will also influence the Previews. Depending on your settings, MADRIX will include all voxels in the rendering process or only the ones that are patched.
Learn more »Performance

 

Included Voxels: All

Included Voxels: Patched Only

 

Patch Mask

When letting MADRIX render all voxels, you can further decide how the Previews work. Voxels that are used [a fixture is set up at this position] are displayed brighter than voxels without LED fixtures. Compared to this, MADRIX offers two choices in order to show or hide voxels that are not used. This will influence all 3 Previews. Positions without fixtures will be dark gray or they will not be shown and set to black.

Note: The Patch Mask will only fully apply, when your performance settings include all voxels, as explained above. If your performance is set to only include patched voxels, the voxels will always be shown opaque. Changing the Patch Mask setting will not influence the Previews anymore.

 

Right Mouse Click on the Preview Output > Patch Mask > Transparent/Opaque
Or go to Previews > Preview Output > Patch Mask > Transparent/Opaque

 

Patch Mask: Transparent

Patch Mask: Opaque

Activate Patch Mask Mode

Deactivating Patch Mask Mode

 

MADRIX License

The Previews will indicate if you are using a higher output [as set by the virtual LED matrix in the Matrix Generator or Patch Editor] than your MADRIX license version provides. Unlicensed areas will be shown darker.

Select Help > About... to check your MADRIX license version and product serial numbers.

 

Output Fully Covered By License

Output Not Fully Covered By License

 

Individual Patch

When setting up an individual Patch in the Patch Editor, there might be areas where no fixtures are located according to your LED installation. These areas without any fixtures will automatically be displayed darker to indicate that this area is not in use.

Preview Benchmark

When running MADRIX for the first time, you will be asked to perform a short benchmark test for the Previews.
Or go to Previews > Benchmark...
Click Start

 

Since using the Previews in 3D Mode can require a certain computer performance, MADRIX allows you to run the Benchmark to see the recommended maximum 3D voxel resolution for your computer.
It is recommended to run this test once for your computer setup.
Please close other programs, windows, and background tasks during the test since they can negatively affect the performance and outcome.
 
More Information:
- MADRIX mainly uses the computer's main processor [CPU] for the effect rendering process.
- MADRIX mainly uses the computer's graphics card [GPU] to display these effects in the Previews.
- The Benchmark evaluates the performance of the computer system regarding the Previews. This means that it mainly tests the performance of the graphics card.
- The Benchmark result does not necessarily represent the overall computer performance. The CPU might be able to handle a higher resolution than the graphics card can display smoothly in the Previews.
- The Benchmark evaluates the performance of the Previews in 3D Mode. The result of the Benchmark will show the total number of voxels your computer should be able to display with sufficient performance when using one or more Previews in 3D Mode.
- The Benchmark result does not represent the performance for 2D.
- You can save overall computer performance when using a 3D Matrix Size by setting the Previews to 2D Mode.
- The Benchmark result does not refer to each Preview independently, but for all Previews in total. That means by default it is assumed that all three Previews are enabled as well as set to 3D Mode.
- You can save computer performance by only setting one Preview to 3D Mode and setting the other two Previews to 2D Mode or disabling them, for example. [When disabling one or several Previews, a single Preview can sufficiently display a higher resolution.]
- The Benchmark result is an information. It shows what is recommended and not necessarily what is possible.
- When exceeding the recommended 3D voxel resolution, MADRIX will ask you if you are sure to use the Preview in 3D Mode. In this way, poor performance can be avoided:

DVI Output And External Previews

The 3 Preview windows explained above are technical representations of the effects MADRIX creates for you. But they are not pixel-perfect outputs.
DVI is another way to work with LED products which requires such a correctly sized output. To use DVI, MADRIX offers other options.

The following MADRIX software license versions offer DVI output:

MADRIX KEY dvi start
MADRIX KEY dvi entry
MADRIX KEY dvi
MADRIX KEY professional
MADRIX KEY ultimate

DVI output allows you to easily control large LED pixel walls or use screen-capturing, for example.

Troubleshooting

Invalid OpenGL Version

MADRIX might show the following error message:

Preview Disabled
Invalid OpenGL Version : 1.1
Minimum Required Version : 2.1

If the Previews show this error message, it means that there is a problem with the graphics card of the computer:

The graphics card might be too old and might not support OpenGL 2.1.
The driver of the graphics card for the Windows operating system might be outdated.

To solve the issue:

Check if your computer's graphics card supports OpenGL 2.1. If it is not supported, your computer/the graphics card does not meet the minimum requirements of MADRIX 3. Please upgrade to a newer graphics card, which supports OpenGL 2.1.
Download and install the latest driver version for your graphics card in order to update the driver. [You might need to restart the computer afterwards.]
