Unrivalled performance for hi-res geometry and texture capture
The LightCage can replay GI and spherical lighting gradients that allow for the retrieval of accurate 3D geometry along with the generation of specular, diffuse and normal maps.
Capture 360 degrees instantaneously
The ESPER LightCage is a geodesic frame with integrated power distribution that is typically deployed with 156 MultiFlash lights. The frame is capable of mounting up to 150 cameras around the subject. When combined with rapidly cycled lighting sequences this allows the rapid capture of image data from every conceivable angle.
Unparalleled lighting control
The ESPER MultiFlash has been specifically designed for use in multi-camera capture. Flash duration and intensity can be controlled independently and the flash offset can be accurately controlled to allow precise synchronisation with the capture system. The MultiFlash comes configured with polarising filters, RGB filters can be fitted on request.
The lighting states can be tightly synchronised with stills, video and machine vision camera systems, allowing for the rapid, reliable and accurate capture of an actors performance.
The LightCage creates even and accurate lighting states to optimise photometric data capture supporting the production of high quality photorealistic assets. The captured images require minimal clean-up and are pipeline-ready for processing.
LightCage controller software
The LightCage controller software has been designed for ease of operation. No complex programming is required. No laborious command-line input or time draining second guessing. ESPER’s LightCage Controller software has been designed to maximise usability, certainty and efficiency.
With a LightCage it is possible to emulate the pioneering techniques developed by Paul Debevec and the University of Southern California Institute for Creative Technologies for generating diffuse maps, specular maps, normal maps. It is worth noting that some techniques may require licensing which can be facilitated through ESPER.
Lighting states can be programmed and accurately synced with any image capture system to produce data sets that provide accurate 3D reconstructions and detailed surface detail and texture information.
The LightCage’s MultiFlash lights have been designed to provide flicker free operation throughout their entire dimming range demonstrated here at 300fps
