Rendering of Unorganized Points with Octagonal Splats
نویسندگان
چکیده
Point sets from range scanners are noisy and do not contain additional data such as normals, which makes it difficult to create a mesh for rendering. We use the moving least-squares (MLS) approximation to get normals and differential information, and approximate the surface near each point by an MLS surface. From this we obtain a splat of a new octagonal shape which approximates the local curvature at a point and allows fast and high-quality rendering. We show several results which demonstrate the practicality and benefits of our algorithm.

متن کاملSplat-based Ray Tracing of Point Clouds
Point-based surface representations have gained increasing interest in the computer graphics community within the last decade. Surface splatting established as one of the main rendering techniques for point clouds. We present a ray-tracing approach for objects whose surfaces are represented by point clouds. Our approach is based on casting rays and intersecting them with splats. Since ray-traci...
متن کاملSplat Based Raytracing
Splat based raytracing refers to the use of raytracing techniques to visualise point models. Point models have surfaces represented by unconnected points, rather than triangles. The use of triangles for rendering is efficient as long as the model complexity is low, and each triangle contributes to a significantly large area of the screen. As triangle based models become increasingly complex, th...
متن کاملHardware-Oriented Point-Based Rendering of Complex Scenes
High quality point rendering methods have been developed in the last years. A common drawback of these approaches is the lack of hardware support. We propose a novel point rendering technique that yields good image quality while fully making use of hardware acceleration. Previous research revealed various advantages and drawbacks of point rendering over traditional rendering. Thus, a guideline ...
