Tripod Sudoku (Fun With Sudoku #12)

This is a very old puzzle that I created for the 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 published this puzzle in the year 2010, I wanted to republish this puzzle after improving the graphics of this puzzle. The graphics of this puzzle looks very simple, but I had a tough time creating an image of this puzzle. The reason is 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 the Puzzles/Sudoku I create does not have an exact square. He was quite right. Yes, the Sudoku grid I was creating was not having an exact square shape. I checked in the Excel sheet that cells vertically and horizontally have exactly the same size, but still due to a bug in MS Excel while showing a 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 the perfect circle.
I am re-publishing this Tripod Sudoku as the 12th Sudoku of the Fun With Sudoku Series. Can you solve this Tripod Sudoku puzzle?

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.
