Splat Rendering
Splat rendering is a computer graphics technique used for rendering 3D scenes represented by point clouds or particle systems, where each point (or 'splat') is rendered as a small, textured primitive (like a disk or square) to approximate surfaces. It is particularly effective for visualizing large datasets, such as LiDAR scans, medical imaging, or fluid simulations, where traditional polygon-based rendering may be inefficient or impractical. The method involves projecting and blending these splats onto the screen to create a continuous visual representation.
Developers should learn splat rendering when working with point cloud data, such as in geospatial applications, virtual reality, or scientific visualization, where it provides a fast and memory-efficient way to render millions of points in real-time. It is also useful in game development for effects like particle systems (e.g., smoke, fire) and in computer-aided design (CAD) for visualizing scanned objects, as it avoids the complexity of mesh generation from raw point data.
