An interactive content control apparatus and method includes a depth information acquisition unit for acquiring an image that includes depth information by capturing a static background object and a dynamic foreground object, and for calculating depth maps based on respective depth values of the static background object and the dynamic foreground object from the image, a display unit for projecting image content including a background image and an object image on a surface of the static background object captured by the depth information acquisition unit, and an image mapping unit for recognizing the dynamic foreground object depending on the depth maps based on the depth values calculated by the depth information acquisition unit, and controlling the display unit so that an object image projected on the surface of the static background object is transferred to and projected on a surface of the dynamic foreground object.

Interactive content control apparatus and method

Disclosed herein is a real-time dynamic non-planar projection apparatus and method, which can reduce visual errors, such as distortion of a screen image or deviation from a border area, upon projecting screen images from a projector onto the surface of a non-planar object that is moved in real time. The presented real-time dynamic non-planar projection apparatus includes a preprocessing unit for preprocessing data related to a static part of a screen image to be projected onto a non-planar surface. A real-time projection unit classifies non-planar objects in the screen image to be projected onto the non-planar surface into a rigid body and a non-rigid body using data output from the preprocessing unit, respectively renders the rigid body and the non-rigid body depending on a viewer's current viewpoint, and projects rendered results onto the non-planar surface via projection mapping.

Real-time dynamic non-planar projection apparatus and method

Disclosed herein are an apparatus and method for generating virtual game clients. The apparatus includes a description grammar module, a description generation module, and a client generation and control module. The description grammar module includes a game packet description grammar. The description generation module generates a game protocol description corresponding to the structure of a packet protocol of a game and a game protocol sequence description corresponding to the relationship of transmission and reception between packets, based on the game packet description grammar. The client generation and control module generates a virtual game client using the game protocol description and the game protocol sequence description.

Apparatus and method for generating virtual game clients

Disclosed herein is an apparatus for collecting game data in order to test performance of a game server. The apparatus includes a capture and filtering module, a control module, and a data management module. The capture and filtering module captures packets, transmitted and received between the game server and each of a plurality of game clients, using the plurality of game clients, and extracts a plurality of necessary data by performing filtering on the results of the capturing. The control module determines the movement route of a game character in such a way as to correspond to the plurality of necessary data, and controls the plurality of game clients based on the movement route. The data management module stores and manages the plurality of necessary data.

Apparatus and method for collecting game data

Disclosed herein is a scenario-based load testing apparatus and method. The scenario-based load testing apparatus includes a packet analysis unit, a scenario creation unit, and a load generation unit. The packet analysis unit creates a virtual map and game grammar by capturing and analyzing packets sent between a server and a client. The scenario creation unit creates a scenario of a virtual user on the virtual map. The load generation unit generates a load by creating packet data corresponding to the virtual user in compliance with the game grammar and the scenario.
