jhcl21 Posted October 10, 2017 Share Posted October 10, 2017 I studying about the attribute copy SOP. And had strange behavior. I used the two grids one is Raw:200,Columns:200 and other is Raw100,Columns:100. The result is repeating 4times on Raw instead of 2times. Why not 2times x 2times? I know if i set the grid to 200 x 100, or attribute transfer can solve it but I want to know about the reason, not a solution. Quote Link to comment Share on other sites More sharing options...
Nache Posted October 10, 2017 Share Posted October 10, 2017 Hi Junji, you should take a close look at what's going on when you copy attribute from grid1 to grid2. In fact you're copying the color of each point, number by number (color ptnum 0 -> color ptnum 0) and when you reach point number 10 001 which you haven't in grid1 it begin at 0 again (color ptnum 0 -> color ptnum 10 001). The 2 grids have a different topology so you get different mapping. In your case you're getting kinda the same image because is 100 x 100 and 100*2 x 100*2. If you change your grid2 to 201x201 you'll probably notice that every thing is a bit messed up, that's why. I don't know if i'm clear enough, you can try your setup with 2x2 and 4x4 grids and display points number, that way you'll see what's going on. Gab.
