in the docs it's written that Partition attributes can only be integer or strings . but i got the same results when partition attribute is float or vector ?? in for each node .
so my point is am i crazy or does the line - “Partition attributes can only be integer or strings” do actually true in other workflow cases ?
-thankYou

1.what's the difference b/w iteration 0 and 1(in block end node) ?
{
1.(a).gather mode set to “feedback each iteration” and iteration set to “0”{in the block begin node} then how come it's showing results of the node b/w block end and block begin 1-times(single times) ? my point is how the iteration is working ?
>>>maybe i'm thinking differently(and houdini is working differently) that's why i'm confused so plz help me clear the confusion .
{i'm wondering the answer –>>it's happening so because when the method is set to “fetch feedback” the node’s input is used as the output for the first iteration ?? plz tell me whether the answer of my own is right or wrong.}
}
2.what's the point of having fetch input option under method menu inside block begin node ?
-thankYou.

1. attribute is ‘marked transforming’ if it's type info or qualifier is set to one of the transforming types as mentioned (Position, Notmal, Vector, Quaternion, Transform Matrix)
you can set those using for example Attribute Create SOP, attribtypeinfo() VEX function, Add Attribute VOP, …
2. transformed means the transform matrix will get applied correspondingly to the type info, so Position attributes will be fully transformed, Vector just rotated+scaled, Quaternion just rotated, …
so yes, it modifies the values of such attributes which for Position attributes can be also thought as changing the location
3. what do you mean by attribute transform? Transform by Attribute SOP? if so then yes, it's the same as Attributes to Transform parameter in that SOP, or in Deformation Wrangle SOP, Bend SOP, Point Deform SOP, or Other Attributes in Bone Deform SOP, …
4. to have all relevant attributes correctly transformed, not just P

1. what the “These attributes are transformed, if they are marked as transforming.” - means in the very first line ?
2. here “transformed” means modification or changing of location or completely different ?
3. is there any similarity b/w attribute transform and this option ?
4.what's the point of having this option available to us ? (reasoning for above questions. )
snapshot :-

i'm very new to all this kind of stuffs like voxels and fields but one thing i cannot get my head around is that
{
1.in the following snapshot what “point” it's references to ?
2. does the object means source object/geometry ?
3.how the distance is measured ?
4. distance is measured from what (means must be measured b/w two location ,so what are the two location ?) ?
5.plz help me with these kind of terminology!!!
}
-thankYou.

CYTEokay,agree with you but is there any workflow for using different choices ?.
Hey papon,
bounding object: you can plug an object, for example, a torus into the second input of the node. all points inside the object get assigned to the group.
bounding volume: does the same but you plug in a volume.
Cheers

tamteanother query >> there is nothing b/w “nothing” in the hscript expression what does that mean ?
several things going on here:
1. this is not VEX, but hscript expression
as you may know you can insert hscript expressions into string parameters by enclosing them in backticks``
so in this case the whole highlighted line is an inserted hscript expression that will first get resolved
you can see it's resolved value fy MMB on the parameter label (Code Snippet in this case)
2.
. is reference to the current node
.. is reference to the parent node (node higher one level)
it's a traditional unix relative path syntax, so ../.. is 2 levels above the current node, etc.

tamteit seems you are an experienced houdini artist . thankYou .
the tooltip describes it quite well
simply put a code in there that you want to be executed before (outside) of the body of the main shader function
what can be deceiving is that it has just a single line UI, but you can type a multi line string in there

in the docs it was written as follows:-
If you wish to use $ for temporary variables, you have to prevent the expansion of variable names or your temporaries will be expanded. However, using $ is not recommended.
but preventing expansion of variable names or temporaries would be expanded means ???
