WebMay 3, 2024 · Black hole ray-tracing programs typically distribute rays on an evenly spaced grid (see, e.g., Gold et al. 2024). In this approach, regions of the image with sharp, bright features are sampled with the same density of rays as the faint regions of only diffuse structure. Black hole images are expected to have regions of both categories. WebApr 3, 2024 · Accretion disc model fitting to optical/UV quasar spectra requires that the highest mass black holes have the highest spin, with implications on the hierarchical growth of supermassive black holes and their host galaxies over cosmic time. However, these accretion disc models did not include the effects of relativistic ray tracing. Here we show …

This technique has the … Webwhich chooses whether to ray-trace or interpolate on a pixel-by-pixel basis. Examples of high-resolution black hole images with this adaptive ray-tracing scheme can be seen in, e.g., Broderick & Loeb (2006). Parkin (2011) also presented an analogous refinement model for adaptive ray tracing, although it was not developed for black hole images.
WebDec 11, 2024 · Curved Spacetime Raytracer. This project is based on my previous raytracer and extended to a curved spacetime by using an approximation of the Schwarzschild metric, which is a solution for Einstein's field equations that describes gravity in the vicinity of a radially simmetrical distribution of matter, without rotation or charge. WebMar 3, 2024 · Load 3D point data from my black hole simulation (no problem, works already) Hook into one of ParaView‘s ray-tracing renderers (ideally the ‚GPU Based‘ one) to update the direction of each ray given its current position and the value of my point data at that position based on a formula I provide.
