New extensions in BS Contact support deferred rendering in real-time

The times of baked shadows and pre-rendered lighting effects in computer graphics have gone. Today advanced shading techniques are possible in BS Contact – in real-time.

Deferred rendering is a technique in which the result of a shading algorithm is calculated by dividing it into smaller parts that are written to intermediate buffer storage to be combined later, instead of immediately writing the shader result to the color framebuffer.

The BS Contact implementation on modern hardware makes use of multiple render targets (MRT) to avoid redundant vertex transformations. The computation and memory bandwidth required to shade a scene is reduced to those visible portions, thereby reducing the shaded depth complexity.

Recently Hong-Kong based company Legendtech pushes the limit of the new BS Contact extensions on their car racing game through a 1103 km2 3D-model of Hong Kong. The following screenshots of BS Contact show results of deferred lighting, screen space ambient occlusion(SSAO) and real-time reflection and refraction as well as motion blur and depth of field generated with post processing shaders.

More information about the deferred rendering functionality and post processing shaders can be found in the BS SDK.

About Bitmanagement Software GmbH

Bitmanagement is a provider of multimedia software with a focus on online interactive 3D visualization. The multimedia technology for 2D/3D, audio and video is realtime and Internetready. Based on the ISOstandard formats VRML/X3D, CityGML and COLLADA, MPEG-4 and Java, it allows an Interactive visualization of concepts and products.

Bitmanagement develops and markets a product portfolio of visualization software, which is composed of visualization software (BS Contact VRML / X3D, MPEG-4, Geo, Stereo and Mobile), documentation (BS SDK Package) for animation and different programming tools up to Workflow optimization such as BS Encrypt.

Bitmanagement was founded in 2002 by three former employees of the blaxxun interactive AG, Munich. The company achieved sales growth and positive result in 2008 and is "cash flow positive" in since its founding.

Bitmanagement is a board member of the "Web3D Consortium" (USA), which is responsible for the standardization and dissemination of 3D ISO standards for the Internet. Bitmanagement is simultaneously also a member of the" 3D Consortium "for the dissemination of stereoscopic visualization.
