A haptic logic and computing paradigm is presented with a basis for multiagent visual computing with the Morph Gentzen logic. The techniques since 1999 are the bases to a haptic logic and multiagent cognition where central affective computing questions might be addressed.The computing model is based on a novel competitive learning with agent multiplayer game tree planning. Specific agents are assigned to transform the models to reach goal plans where goals are satisfied based on competitive game tree learning. Affectice computing is addressed with a new haptic computing logic. Questions such as 'Are intelligent decisions based on emotions?' are addressed. Further questions on emotions and consciousness models studied. (The IM_BID model is introduced for planning and spatial computing. Visual intelligent objects are applied with virtual intelligent trees to carry on visual planning. New KR techniques are presented with G-diagrams and applications to define computable models and relevant world reasoning. G-diagrams are diagrams defined from a minimal set of function symbols that can inductively define a model. G-diagrams are applied to relevance reasoning by model localized representations and a minimal efficient computable way to represent relevant knowledge for localized AI worlds. Diagrammatic reasoning is defined in terms of inferences directed by the G-diagrams for models. The techniques show how computable AI world knowledge is representable. G-diagrams are applied towards KR from planning with nondeterminism and planning with free proof trees to planning with predictive diagrams. The IM Morph Gentzen Logic for computing for multimedia are new projects with important computing applications since the author's and contemporary projects on diagrammatic computing. The basic principles are a mathematical logic where a Gentzen or natural deduction systems is defined by taking arbitrary structures and multimedia objects coded by diagram functions. The techniques can be applied to arbitrary structures definable by infinitary languages. Multimedia objects are viewed as syntactic objects defined by functions, to which the deductive system is applied. A basis to VR computing and computational illusion is presented.
