Are there any rendering alternatives to rasterisation or ray tracing?

WebConcept. Ray casting is the most basic of many computer graphics rendering algorithms that use the geometric algorithm of ray tracing.Ray tracing-based rendering algorithms operate in image order to render three-dimensional scenes to two-dimensional images. Geometric rays are traced from the eye of the observer to sample the light travelling … WebWe present a novel framework named NeuralRecon for real-time 3D scene reconstruction from a monocular video. Unlike previous methods that estimate single-view depth maps separately on each key-frame and fuse them later, we propose to directly reconstruct local surfaces represented as sparse TSDF volumes for each video fragment sequentially by a …
