I figured out that exploiting the mvncdf() function i'm able to compute the probability under rectangular area or under a semiplane whose constraint be parallel to X or Y axis (P < x1 , P < y1). > > Now my problem is, how can i compute the probability under a semiplane whose constraint is not parallel to X or Y axis.

Integrating the bivariate normal distribution over arbitrarily defined regions in 2d seems to me is such a fundamental problem in statistics that a google search should help.
