Multi add/mult nodes

11 aastat tagasi • uuendaja 11 aastat tagasi • 6

So this is probably a 'nice to have' but I think it is worth thinking about as I hope its not too difficult..

I am doing this

half4 cumulative = t1 * color.r + t2 * color.g + t3 * color.b + t4 * color.a;
half4 cumulativeNorm = t1b * color.r + t2b * color.g + t3b * color.b + t4b * color.a;
fixed vertcolors = color.r + color.g + color.b + color.a;

if(vertcolors != 0)
{

cumulative /= verts;

cumulativeNorm /= verts;

}
cumulative = lerp(basetex, cumulative, vertcolors);

It ends up looking like this..

Obviously the encapsulated nodes will be useful in the future but..

The 4 multiplies and adds in a row..

Maybe have a grey out extra nodes, they only become available once A and B are used and are obviously optional but an almost unlimited number could then be done in a row..

It's a planned feature, but hasn't gotten priority yet! The same goes for the Append node, which should also support more than two inputs :)
Thanks for the suggestion and images!

Edit: Multi-input Add and Multiply nodes are now implemented in 0.17!
They support up to 5 inputs now instead of just two

There should be a node with three input vectors and an input reference vector. Imagine the inputs:
[ref]
[c1]
[c2]
[c3]
[c4]

Outputting a vector which is: c1*ref.r + c2*ref.g + c3*ref.b + c1*ref.a
It's *very* similar to the dot product. I believe they are both Inner products, so perhaps this node could be called inner product? Or is it a matrix product?

Hmm, to be honest I would hate to call it, the I love the idea of the node for sure. Inner Product seems that it better describes what is going on though..
