—Caricatures are models of persons or things in which certain striking characteristics are exaggerated in order to create a comic or grotesque effect. This paper is concerned with a strategy for automatically generating caricatures of three-dimensional models based on anthropometric measures and geometric manipulations by influence zones. In the proposed(More)
Human T-lymphotropic virus I (HTLV-I) is an etiologic agent in adult T cell leukemia. In an effort to understand the relationship between HTLV-I infection and malignant transformation, we have examined transferrin receptor expression in HTLV-I-infected cells. Transferrin receptor expression in normal T cells is tightly regulated and essential for cell(More)
The phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA) induced megakaryoblastic differentiation and c-sis expression in the human hematopoietic stem cell line K-562. This induction occurred at the transcriptional level, as determined by a nuclear runoff transcriptional assay, and was not a generalized effect of TPA, since the treatment of other(More)
Control for physically based characters presents a challenging task because it requires not only the management of the functional aspects that lead to the successful completion of the desired task, but also the resulting movement must be visually appealing and meet the quality requirements of the application. Crafting controllers to generate desirable(More)
A number of techniques for generating geometric models of human head and body are in use nowadays. Models of human characters are useful in computer games, virtual reality, and many other applications. The complexities involved in generating such models, however, impose heavy limitations on the variety of characters produced. In this paper, diploid(More)
We explore an approach to full-body motion editing with linear motion models, prioritized constraint-based optimization and latent-space interpolation. By exploiting the mathematical connections between linear motion models and prioritized inverse kinematics (PIK), we formulate and solve the motion editing problem as an optimization function whose(More)
This paper addresses the problem of generating natural behavior of autonomous virtual characters. Inspired by the fields of Embodied and Enactive Artificial Intelligence, we postulate that natural behavior is the result of a coupling between the agent and the world where it lives, which leads to a coherence between its actions and its surroundings. In this(More)
—Virtual reality has applications in different fields of knowledge such as engineering, science, arts, entertainment and education. In this work, virtual reality is used to help solving the problem of missing persons. The proposed methodology uses simulated diploid reproduction of virtual characters carefully modeled taking into account the traits of the(More)
