Bus inside bus (nested buses), no can do?

Maybe this has been noted before, but I think Synthmaker can't put buses inside buses.

I'd like to have a combination bus like x,y,z and put several of them inside a bigger combination bus. The x,y,z would be a kind of custom "struct" data type, and the outer bus would be a kind of array holding those data types. It doesn't seem to work. I'm only getting zeros out from the bus.

If you ask what I'd need it for... it's quite useless stuff really. I just tried creating a basic 3d rotating cube without using the code component... 😉 I got it almost finished, but when I thought I'd get a picture on the screen, I wasn't getting any values out from the calculations, and I traced the problem down to the buses. It's fun to tinker with Synthmaker while watching TV. 😀

Sorry i don't know the answer to your question, I made a rotating cube and star but they were only 2d, if possible could you post a screenshot as this sounds very interesting, does it rotate on all it's axis xyz?

It doesn't output anything yet, because all I get is zeros...

It's really basic. There's a bus of eight points (vertices if you like) each having x, y and z coordinates. The data path starts from the cube's original vertex data, going through the usual phases: rotation (matrix multiplication with a rotation matrix), translation, projection, drawing.

So far I only had a constant identity matrix as the rotation matrix to get something visible, so the cube would have been static anyway.

Rotation by matrices? Taylor series? Arcotangents? This place is like home... 🙂

Hmm. You're right Kitchen Sink, it doesn't work but I think it should. Leve this with me.

I totally agree with this.. I'm lost in a totally foreign solar system but I like it very much so far!

Nice to see you back here 🙂

Still on the list this one - it will get sorted I promise.
