Anamorphosis refers to a category of images that are intentionally distorted, making them unrecognizable when viewed directly. Their true form only reveals itself when seen from a specific viewpoint, which can be through some catadioptric device like a mirror or a lens. While the construction of these mathematical devices can be traced back to as early as the 17th century [28], they are only interpretable when viewed from a specific vantage point and tend to lose meaning when seen normally. In this paper, we revisit these famous optical illusions with a generative twist. With the help of latent rectified flow models, we propose a method to create anamorphic images that still retain a valid interpretation when viewed directly. To this end, we introduce Laplacian Pyramid Warping, a frequency-aware image warping technique key to generating high-quality visuals. Our work extends Visual Anagrams [17] to latent space models and to a wider range of spatial transforms, enabling the creation of novel generative perceptual illusions.

Abstract An ongoing challenge in fluid animation is the faithful preservation of vortical details, which impacts the visual depiction of flows. We propose the Impulse Particle‐In‐Cell (IPIC) method, a novel extension of the popular Affine Particle‐In‐Cell (APIC) method that makes use of the impulse gauge formulation of the fluid equations. Our approach performs a coupled advection‐stretching during particle‐based advection to better preserve circulation and vortical details. The associated algorithmic changes are simple and straightforward to implement, and our results demonstrate that the proposed method is able to achieve more energetic and visually appealing smoke and liquid flows than APIC.

SUMMARY: TiFoSi (Tissues Forces & Signaling) is an efficient computational tool for performing mechanobiology simulations of planar epithelia. A drawback of this tool is that it relies on an XML configuration file (input data) that can be cumbersome to set up and/or decode due to the endless possibilities of the software. Moreover, some modeling know-how is needed in order to provide equations that describe gene regulatory interactions. These factors limit the usability of this tool for users with a weak computational and/or mathematical background. Here, we introduce ANISE (grAphical coNfigurator of TiFoSi In Silico Experiments), a web-app that allows to easily setup the configuration of mechanobiology simulations using TiFoSi. The application covers all the configuration modules in TiFoSi comprehensively (from basic to advanced editing options) and uses a graphical approach (e.g. to build the modeling equations of gene regulatory networks).

Webmail clients provide millions of end users with convenient and ubiquitous access to electronic mail - the most successful collaboration tool ever. Web email clients are also the platform of choice for recent innovations on electronic mail and for integration of related information services into email. In the enterprise, however, webmail applications have been relegated to being a supplemental tool for mail access from home or while on the road. In this paper, we draw on recent research in the area of electronic mail to understand usage models and performance requirements for enterprise email applications. We then present an innovative architecture for a webmail client. By leveraging recent advances in web browser technology, we show that webmail clients can offer performance and responsiveness that rivals a desktop application while still retaining all the advantages of a browser based client.
