Title: Corona development progress
Post by: Ludvik Koutny on 2012-08-27, 14:35:44
Hi,

i know it has been a long time since any update here on the forum and that it seems quite dead. The reason that there has been so few updates is that we have been working very hard to reach beta phase.

Beta phase means Corona will have all the basic feature set necessary for production use at least in visualization segment. We have implemented a lot of features and currently focus on stabilizing them. Once that is done, beta version will be released. Beta phase will be focused on making Corona as stable and bug free as possible and prepare it for final release.

Currently, following features are implemented and being stabilized:

- Render elements with ability to be properly outputted and also saved as EXR channels. Crucial elements like matte element have been added to allow proper use of alpha masking based on material IDs, object IDs and custom selections.


- Area light directionality feature (similar you may know from Vray renderer) which allows you to gradually change light distribution of area light from diffuse to spotlight distribution.


- Bokeh lens effect for DoF has been added.


- Motion blur has been added.


- Material layering has been added via support of Blend material.


- Added custom material editor previews for more convenient material tweaking in material editor.


- Micro-triangle displacement has been added


Here are some pictures. Many of them don't look neat or impressive, but most of them were rendered with development build with no optimization (20-50 times slower than final build), which is very slow, so many of them are noisy, or have high rendertimes. In public build, those features should work fast and handle complex scenes, so don't judge based on these pictures, they are just a little sneak peek ;)

Corona mask is really great render element!
thank you!

Great Work.

What`s next for corona?..., what`s the roadmap?.., any aprox. date for the next release alpha or maybe a beta?

Thanks and keep going with the fantastic work!

I'm taking a break until christmas to develop new unbiased GI algorithm for extremely difficult scenes.

No, metropolis sucks (but I'll implement it some day anyway). It will be a universal method, pluggable to any other. I want to primarily add it to the VCM thing.

What is VCM ?

The future of Corona looks amazing.

Some links to get creative juices flowing to make Corona a faster better rendering engine.

1)  http://www.mitsuba-renderer.org/
The documentation manual here is really interesting in that it talks about all these different ways people have solved rendering different things quickly in the past like bidirectional path tracing plus so much more.  I thought it was a good read.

2) http://iwantthatcake.wordpress.com/2012/02/22/real-time-radiosity-geometrics-enlighten/
Since, it's mentioned other places that if all the CPU power was used right we could have real time GI this seemed interesting that it was already done and being used in video games like Battlefield 3.  I know it's not 100% realistic, but for the rendering time taken to make the scene it's pretty great.  A super fast rendering option like this could be really useful in some cases even if some bake time is needed to start.

3)  http://realtimeradiosity.com/demos/
Links to ways people have tried to do real time GI in the past.  It's interesting the results that each method achieved.
