Dali Renderer hasn’t been updated for a long time. This is due to a lack of feedback to the author and, consequently, low motivation. Comments, criticism, and other feedback are very important to the author. With them, updates could come out more often.

In the future, a new stage of improving caustic rendering is planned, along with a step-by-step transition of calculations to the GPU.
