RGB Matrix with irregular shape - is this possible in madrix

[heystew]

Hello,
potential new madrix user here. Plenty of experience in RGB, but have only toyed with the Madrix demo briefly. I am creating some RGB structures using pixel strings that are not a standard rectangle. I've played with the matrix creator and the fixture creator to build a string, but it seems that they only support rectangles.
Can anyone point me to some information or have experience with this?
Let's take for example that I want to create a matrix that is a circle. The LED strings would loop back and forth just like in a rectangular matrix, but each row/column is not the same length.

I searched the forum but could not find any reference to this.

Thanks,
dave

Hi,
sometimes you have to think different.
I am not sure what you have exactly in mind so i describe two possibilities.
.
1.
Lets say your led bars are one behind each other to build a circle shape.
Lets say you have 10 led bars and each led bar have 10 pixel.
In this case your matrix in MADRIX could be 100 pixel in x and just one pixel in y.
Patch your fixtures using the Matrxi Generator or the patch editor of MADRIX.

2.
Lets say you have 100 led bars each 10 pixel in a row and the 100 led bars are right beside each other but vertical.
In this case just use a matrix inside MADRIX of 100 Pixel in x and 10 pixel in y.
You know just imagine that the left and the right side of the matrix are beside each other because they build a circle.
In some effects like the SCE Ticker you have a continous check box which is made for such special cases, so for example a text running around a tube without break.

For the second case it doesn´t matter if the led bars you patch are of different size/length. For this you just have to setup the desired position in y.

Thanks for the information and reply. Unfortunately my choice of a circle as an example was a poor one. My intention is to build various 2D shapes that are not in a rectangular form. Attached is a picture of what i meant when i said circle.. this is greatly simplified as it will actually have 100's of pixels, so it will be much more complex to recreate.

thanks,
Dave
