Abstract: Systems and methods for generating a video of a user-defined virtual reality scene are disclosed. Exemplary implementations may: obtain a scene definition; obtain camera information for multiple virtual cameras to be used in generating a two-dimensional presentation of the virtual reality scene; execute a simulation of the virtual reality scene from the scene definition for at least a portion of the scene duration; obtain camera timing instructions specifying which of the virtual cameras should be used to generate the two-dimensional presentation of the virtual reality scene as a function of progress through the scene duration; generate the two-dimensional presentation of the virtual reality scene in accordance with the camera timing instructions and the camera information.

Abstract: A system for preventing pregnancy and covertly treating erectile dysfunction is used to help the user maintain an erection by constricting the penis of the user. The system includes a condom which, like a traditional condom, is used to capture semen in order to prevent pregnancy. The system includes a first constriction band, a second constriction band, and a constriction ring which each work to constrict areas of the penis to limit blood flow so that an erection may be maintained during sex. The condom includes a tubular body and a length-adjustable head. The tubular body helps to hold the length-adjustable head in place over the head of the penis. The length-adjustable head captures ejaculated semen and also helps to keep the first constriction band in place.
