List Input node about sverchok

[zeffii]

The only real way to know is by trying :)

[ly29]

Made it look a bit better.

[zeffii]

also convenient for vectors :)

[nortikin]

instead of series, may be as medial way from formula2 and text cvs input

[ly29]

Do mean middle way @nortikin ?

Anyway, a quick test what vector input could look like.

[ly29]

And just for fun, matrix input.

[zeffii]

i was looking for a simple identity matrix, this node could have presets!..edit: tho I don't know of any static matrices that would be handy

[ly29]

They are all basiclly ready. Yes or no? List Input feels good to have atleast.
For Matrix Input the ID matrix would be default of course.
We also need matrix math, did list once of the modes to make something like scalar math and vector math. It made my head hurt with socket handling idea I had then. Now know a bit more about that.

       m_in_m_out = {
            "MUL_MM"    :   (lambda m,n  : m*n , 2),
            "INV"       :   (lambda m    : m.inverted(), 1),
            "ADJ"       :   (lambda m    : m.adjugated(),1),
            "ADD"       :   (lambda m,n  : m+n, 2),
            "SUB"       :   (lambda m,n  : m-n, 2),
            "NORMALIZE" :   (lambda m    : m.normalized(),1),  
            "TRANSPOSE" :   (lambda m    : m.transposed(),1),
        }

        mv_in_v_out = {
            "MUL_MV"    :   (lambda m,v : m*v,2 )     
        }   
        vm_in_v_out = {
            "MUL_VM"    :   (lambda v,m : v*m,2 )     
        }
        m_in_s_out = {
            "DET"       :   (lambda m   : m.determinant(),1 )     
        }
        ms_in_s_out = {
            "SCALE_MUL"       :   (lambda m,s : m*s,2 )     
        }

in has to have out

[zeffii]

believe it or not, I have not used Matrix yet in Sverchok :)

[ly29]

@nortikin "in has to have out"
I don't understand.

[ly29]

#125 List Input node

[nortikin]

i don't believe @zeffii
@ly29 in node always needs correspondint out node to it, so, node, that give matrix has to have node taking. But in this case i'm not sure.

[ly29]

@zeffii
Well, Otho projection to XY, YZ and XZ perhaps.

[zeffii]

yeah, drop vectors to ground plane

[ly29]

@nortikin
I understand, well it kind makes sense for Vector Input and Matrix Input to work like Integer and Float. But for List Input I don't think it makes sense.

[zeffii]

is this matrix node implemented yet?

[ly29]

Yes, some small fixes, can do it tomorrow.
The vector one is not needed anymore with vector in list input and new vector in

[zeffii]

cool! I needed an easy way to make matrices
