Sohel Rahman, Bangladesh University of Engineering and Technology, BANGLADESH The PRISM framework has the potential to greatly accelerate development of volume rendering for medical applications by promoting sharing and enabling faster development iterations and easier collaboration between engineers and clinical personnel.Ĭitation: Drouin S, Collins DL (2018) PRISM: An open source framework for the interactive design of GPU volume rendering shaders. Finally, we demonstrate the simplicity of our system in a usability study with 5 medical imaging expert subjects who have none or little experience with volume rendering. More importantly, we demonstrate the flexibility of the framework by showing how several volume rendering techniques can be implemented in PRISM with no more than a few lines of code. We show that in its default mode, the PRISM framework produces images very similar to those produced by a widely-adopted direct volume rendering implementation in VTK at comparable frame rates. For programmers, the interface enables real-time editing of the code inside the blocks. A graphical user interface allows clinical users to easily experiment with pre-existing rendering effect building blocks drawn from an open database. In this paper, we propose a new open source framework called the Programmable Ray Integration Shading Model, or PRISM, that implements a complete GPU ray-casting solution where critical parts of the ray integration algorithm can be replaced to produce new volume rendering effects. Although the computer graphics community has proposed several solutions to address specific visualization problems, the medical imaging community still lacks a general volume rendering implementation that can address a wide variety of visualization use cases while avoiding complexity. Despite several advances in the field, it remains a challenge to produce an image that highlights the anatomy of interest, avoids occlusion of important structures, provides an intuitive perception of shape and depth while retaining sufficient contextual information. ![]() Now it’s time to shoot your Instagram Reel.Direct volume rendering has become an essential tool to explore and analyse 3D medical images. ![]() That way, you’ll gain a visual understanding of how your Reels will turn out - and have a clear plan to work from! Step #2: Shoot Your Instagram Reel Once you’ve got a solid understanding of your direction, storyboard your content by breaking down the clips you need to shoot in order to make the concept work. ![]() Who is your target audience and what type of content will speak to them? It could be tutorials, behind-the-scenes, or a day in the life.įrom there, spend time perusing the app and take stock of visuals, text, trends, and aesthetics that you could borrow inspiration from. How will your Reels content be cohesive with your Instagram feed posts or Stories? What topic would make the most sense for your business or brand - fashion and styling? Food recipes? Wellness tips? Here are some questions to answer to get you started: So, before you step in front of the red light, it’s best to put a plan in place. You know how the saying goes, failing to plan is planning to fail.
