HALCA is an interface to the Cal3D library and extends this with GLSL shader support, morph animations, hardware accelerated morph targets(blend shapes), Dual Quaternion skin shaders, JPEG texture files, direct joint manipulation and other additions to the animation system. The Cal3D library is available in source code from http://home.gna.org/cal3d/ An overview of the HALCA architecture is given in the following figure Figure 1. Figure 2 shows a video where HALCA was used to visualise an avatar in first person perspective that moves like the participant. The video is from our 2010 SIGGRAPH paper on an experiment about place illusion and plausibility. Read More blog comments powered by Disqus
