Bloom and God rays in Minetest 5.7.0

by Neuromancer » Post

I just saw this video, and am surpised that no one is talking about it!
Here' s the video description: The work on the graphics pipeline and effects for Minetest 5.7.0 continues.
Enjoy a jungle exploration video featuring all the visual effects currently in development:
* Bloom (merged!),
* Dynamic shadows improved with realistic color tints (soon to come)
* Auto-exposure (soon to come)
* Godrays (soon to come)

It is indeed pretty exciting. I had posted some screenshots of the shaders in action taken from x2048's 'bfs' branch in the screenshots thread, but I'll put them here as well.

Can normal light sources make godrays. Also can you change the direction of the godrays. Also you should be able to change the color of the godray.

godrays are tied to the directional light sources - Sun and Moon - the only non-voxel light sources in Minetest as of now.

You cannot change the direction of godrays, are they are not objects. It's a light effect that simulates scattering of light in the air based on relative positions of other objects. They follow the position of the Sun, for example.

The color of the godrays will be dependant on the color of the light emitted by the Sun/Moon, support for that is in the shaders.

I like the automatic exposure. I assume that it can make playing Minetest more healthy because people would no longer need to stare at dim frames when they are inside a cave. It may also make it possible to implement torches which shine with a significantly lower intensity than the sun.

Slightly offtopic: Another graphics feature which could be interesting for Minetest is stochastic texture sampling:
