Progressive generation of images is one of the important research areas of computer graphics. Especially, when the image generation takes too much time the users want to see the progress in the rendering process. The user may decide either to continue the rendering process or stop the rendering according to the current view of the image.
Progressive Path Tracing with Explicit Light Sampling
https://computergraphics.stackexchange.com/questions/5152/progressive-path-tracing-with-explicit-light-sampling
Progressive Path Tracing with Explicit Light Sampling. Ask Question Asked 4 years, 11 months ago. ... There are multiple areas in path tracing that can be importance sampled. ... // Get the new ray direction // Randomly (uniform) choose whether to sample based on the BSDF or the Lights float p = sampler->NextFloat(); Light *light = m_scene ...

Ray tracing through progressive ophthalmic lenses

Ray-tracing through Progressive Addition Lenses (PAL) has been performed. PAL is a deep non rotationally symmetric asp1ric lens used for the compensation of presbyopia. PAL and its mathematical model are presented. The special features of the ray-tracing program due to the model of the lens plus eye system are detailed. Typical results are presented showing in …
Real-Time Ray Tracing | Unreal Engine Documentation
https://docs.unrealengine.com/4.26/en-US/RenderingAndGraphics/RayTracing/
Under Engine > Rendering, enable Ray Tracing. To enable Ray Tracing, Support Compute Skincache must be enabled for the project. If it is not already enabled, you'll receive a message dialogue asking if you would like to enable it now. If so, click Yes. Restart the engine to launch the Editor with DX12 and to enable Ray Tracing for your project.
How to implement progressive rendering in a CPU based …

In the renderer just pick a random pixel to sample / trace and add the resulting color to that pixels RGB values and add one to it's 'number of samples' value.
Lecture 17: Recursive Ray Tracing - Rice University
https://www.clear.rice.edu/comp360/lectures/old/RayTracing.pdf
Ray Tracing Algorithm For each pixel: i. Find all the intersections of the ray from the eye to the pixel with every object in the scene. ii. Keep the intersection closest to the eye. iii. Compute the color and intensity of the light at this intersection point. Render the scene by displaying the color and intensity at each pixel.
Progressive Radiance Evaluation - University of Toronto
http://www.dgp.toronto.edu/~guo/Radiance/index.html
Based on the hierarchical integration technique by Kajiya, Painter has proposed an adaptive sampling method for progressively refining a ray traced image. Compared to Painter's successful system, our system generates far better images for the same amount of computation time.
