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
