Real-time ray tracing of implicit surfaces on the GPU
https://pubmed.ncbi.nlm.nih.gov/20075486/
In this paper, we present a ray-tracing procedure to render general implicit surfaces efficiently on the GPU. Though only the fourth or lower order surfaces can be rendered using analytical roots, our adaptive marching points algorithm can ray trace arbitrary implicit surfaces without multiple roots, by sampling the ray at selected points till a root is found.

Real-Time Ray-Tracing of Implicit Surfaces on the GPU
https://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.99.9031
In this paper, we present a ray-tracing procedure to render general implicit surfaces efficiently on the GPU. Though only fourth or lower order surfaces can be rendered using analytical roots, our adaptive marching points algorithm can ray-trace arbitrary implicit surfaces exactly, by sampling the ray at selected points till a root is found.

efficiently finding the first ray-surface intersection point where the surface is not given in an explicit form. Our implementation uses the sphere tracing algorithm to attack this problem and runs on the GPU to achieve high frame rates. We also discuss secondary issues like shading and texturing implicit models. Keywords: Sphere Tracing, Implicit Surface, Distance Transform, …

The efficiency of the ray tracing of implicit surfaces is improved by means of the evaluation of groups of rays instead of individual ones, which permits thus saving com-putational time in the entire ray tracing process. The quality of the visualization is improved by means of the creation of an adaptive anti aliasing algorithm. Using this

3.1. Ray tracing implicit surfaces A surface S in implicit form in 3D is the set of solutions of an equation f(x,y,z) = 0(1) wheref: 3⊆R →R.Inraytracing,weseektheintersec-tion of a ray p (t) =o+td (2) with this surface S. By simple substitution of these position coordinates, we derive a unidimensional expression f t(t) = f(o x+td ,o y+td ,o z+td)(3)

closest to the ray origin that satisfies a primary ray’s explicit equation and the primitive’s (e.g., triangle’s, sphere’s) implicit equation. An explicit equation for a surface generates points on the surface from parameters; for a ray with origin P and direction ˆ!, it is X(t)=P +ˆ!t. An implicit equation for a surface defines

Singh and Nayaranan (2009) used the GPU for ray tracing implicit surfaces and showed that “ray marching” methods like sphere tracing are suitable for the GPU in terms of performance. Ray tracing based methods require time consuming computations (Akenine-Möller et al., 2008) that might not be possible to run in real-time on the CPU when a ...
