Hibernate, transactions and data size

Image
0 I am currently using jpa/Hibernate and Oracle in my project. I have a service demarcated with transaction boundaries. In this boundary I have a insert/update of blob which can be max size of 200 mb. Considering data size do transaction have any limit? With this data any impact exceptions or degradation is possible? Couple of factors I checked is transaction timeouts and Oracle packet sizes (tdu and sdu). Any pointers is much appreciated! spring oracle hibernate jpa transactions share | improve this question asked Nov 13 at 20:56 G Shenoy 55 10 ...

Transformation of 3D objects related to vanishing points and horizon line

Image
1 I'm trying to computing the exact prospective transformation of a 3D object starting from a vanishing points and horizon line of a picture. What I want is, fixed the vanishing points and horizontal line of a picture, I want rotate and skew an 3D object according with vanishing points and horizontal lines that I set starting from the picture Below the final result that I expected. How can I obtain this result? What kind of transformation can I use? In this video is possibile to see the result that I want. https://www.youtube.com/watch?v=EsSerR-AjEk graphics 3d camera-calibration perspective perspectivecamera share | improve this question edit...
