Manual camera placement for a particular scene requires repeated processing and calculations, which will take a lot amount of time and cost. Therefore, automatic camera placement in a virtual environment is suggested. The camera placement is not only done automatically, but it also incorporates a directors style. Incorporating a directors style in a cinematic product will create an impressive ambiance. In this research, an approach based on fuzzy logic is used. This research uses a game simulation with three different scenes and some events ? such as running, jumping, squatting, and fighting ? as well as two different styles. The camera placement in this research is not merely based on fuzzy output, but it also utilizes several additional modules so that the result corresponds more to the real world. In this game, there is an event selector for each scene to validate the event sequence. There is also a state director module which functions as a virtual camera operator in the animation so that the camera movement will correspond to cinematographic principle. Camera operator holds a role in the calculation of camera position based on x, y, and z-axes, as well as in the smoothing of camera placement coordinates. The output of this simulation is validated using histogram profiling, and from the resulting histogram, it will be concluded whether the camera placement is suit according to a directors style.
