(PDF) Real-time Caustics in DirectX Raytracing
https://www.researchgate.net/publication/348590385_Real-time_Caustics_in_DirectX_Raytracing
Caustics is a fundamental property of realism in computer graphics. One of the greatest challenges to render this phenomenon at interactable framerates. This paper presents a …
Real-Time Ray Traced Caustics - researchgate.net
https://www.researchgate.net/publication/354065234_Real-Time_Ray_Traced_Caustics
We present two real-time ray tracing techniques for rendering caustic effects. One focuses on the caustics around metallic and transparent surfaces after …
CausticOne + CausticGL = Real Time Ray Tracing | Geeks3D
https://www.geeks3d.com/20090317/causticone-causticgl-real-time-ray-tracing/
CausticOne is a raytracing graphics accelerator card that enables your CPU/GPU to render 3D imagery 20x faster than it can today. From what I understand, it’s a bit like Ageia PhysX PPU, it’s a card that performs ray tracing computations and the developer can fetch the results (via an API, CauticGL) and send them to the GPU (NVIDIA or ATI).
Rendering the Real-Time Caustics with DirectX Raytracing
http://ceur-ws.org/Vol-3027/paper4.pdf
The creation of the caustic visibility maps replaces the first step of ray tracing. The use of rasterization in this case significantly reduces the computation time and allows determining areas within which it makes sense to trace further rays. This also allows us …

Open the material editor to the Details tab and check Cast Ray Traced Reflection Caustics and Cast Ray Traced Refraction Caustics, if the material is transparent. After configuring those settings, Figure 4 shows that the default caustic effects can then be seen around the glass and metal objects.
Real Time Ray Tracing at 5 FPS with CausticRT Raytracing System
https://www.geeks3d.com/20090420/real-time-ray-tracing-at-5-fps-with-causticrt-raytracing-system/
The CausticOne is the hardware side of CausticRT and offloads all raytracing calculations from CPU/GPU. CausticGL is the software side of CausticRT and is a modified version of OpenGL ES 2.0 with a set of specific extensions that allow to cast rays within GLSL shaders. The CausticOne is not the card for end-users.

According to Caustic, this is because the advanced shading and lighting effects usually seen in ray-traced scenes, such as caustics and refraction, can’t be accelerated on a standard GPU because of...

At GDC 2019, Holger Gruen presented a method based on caustics mapping to implement surface and volumetric caustics on DXR, which made real-time, ray-traced water caustics feasible for games. This became the basics of our approach. Compared to a regular mesh that casts caustic, a water surface is highly dynamic and interactive.
Caustic Graphics: Hardware Raytracing
