Tripod Sudoku (Fun With Sudoku #12)

This is very old puzzle which I created for 10th 24 hour Championship.
I have seen this puzzle appearing in the following championships
Oguz Atay Puzzle Contest (OAPC)
"18th World Puzzle Championship, Antalya (Turkey)"

"The Last Sudoku Competition Before World Sudoku Championship"
Even though I have published this puzzle in year 2010, I wanted to republish this puzzle after improving graphics of this puzzle. Graphics of this puzzle looks very simple, but I had tough time creating image of this puzzle. Reason being that I use MS Excel to create graphics and now becoming very comfortable with creating any puzzle images using Excel. During my stay in Mumbai for Times Sudoku Championship 2014, I got feedback from Rohan that Puzzles/Sudoku I create does not have exact square. He was quite right. Yes, the Sudoku grid I was creating were not having exact square shape. I checked in Excel sheet that cells vertically and horizontally has exactly the same size, still due to bug in MS Excel while showing print preview, it was distorting this size. I corrected this problem after switching view in Excel. But for this I was hit by another problem. MS Excel distorts the shapes inserted in the sheet too. I had a very tough time keeping circles in this Sudoku as perfect circle.
I am re-publishing this Tripod Sudoku as 12th Sudoku of  Fun With Sudoku Series.
Rules of Tripod Sudoku 
Fill the grid with digits 1-6 and divide the grid into some regions, so that each digit appears exactly once in every row, column and region. All points where three lines meet are given. There are no points where four lines meet.
