Linear Wash Beam

Recommended Posts

Hi All,

I'm wanting to build some GDTF files of linear RGBW fixtures which I have in a venue. They are wash fixtures which uplight the wall. 

What's the best way to show the beam for this? - Is it possible to make the beam diffused around the edges instead of being a hard spot when it is imported into MA3 3D? And is it possible to make the beam of the fixture asymmetric / fit the entire fixture length (1m) rather than just be a round symmetrical point beam? 

Any help is greatly appericated!

Hello @hantoo,

these are largely implementation details in visualizers, as for your definition, you can choose a beam type in the Builder → Geometry → geometry chain → Beam:

The BeamType describes how the Beam will be rendered.
— “Wash” – A conical beam with soft edges.
— “Spot” – A conical beam with hard edges.
— “Rectangle” – A pyramid-shaped beam with hard edges.
— “None” – No beam will be drawn, only the geometry itself will emit light.

So for soft edge you can choose the "wash", for asymmetrical you can choose "rectangle". You could also build an array of "pixels", defined as "wash", especially if these can be controlled individually, this will create the asymmetrical, soft type of output.

Hope this helps

Petr
