I want to use an array inside a function, for example:
function(x,y,z){MYARRAY[][]}
I can hard code an array index, and it is fine:
eg. function(x,y,z){MYARRAY[2][3]}
, however I can't create an array index from a function. I get an error "Float
expected but vector or color expression found"
e.g. function(x,y,z){MYARRAY[max(min(int(x),9),0)][max(min(int(y),9),0)]}
parsing the function inside the array indices we return valid integer indices,
but it appears that POV is not parsing it this way: rather than precalculating
the function using the "x" and "y" values from the function, it is seeing them
as x and y vectors (<1,0,0>, <0,1,0>) which gives the error. Changing to a
different reference from x,y,z eg.
e.g. function(xx,yy,zz){MYARRAY[max(min(int(xx),9),0)][max(min(int(yy),9),0)]}
results in an undeclared indetifier 'xx' error.
I there some way I can work around this and force the function inside to be
calculated into my index value before the array tries to parse it?
