Added support for octahedral impostors.
Had this on the backburner for a while.
Single quad, 1024x1024 texture resolution
The intention, of course, is to serve as an LoD and not to be viewed up-close
The bake happens in-engine and is fully runtime capable.
Bake includes full G-buffer: normals, ORM, albedo, depth
Bake parameters:
atlas texture resolution - how big is the overall texture, here it’s 1024
grid resolution - how many individual projection views we bake, here it’s 16x16
bake mode - full octahedral or hemioctahedral. Hemioct is missing the bottom projection views, but gives you about 2x resolution elsewhere
Here’s a sample bake with just 6x6 grid to help illustrate how it works
I wrote a little on this before.
Also, fyi - the engine is alive and well, just continues as proprietary engine. I’m in the process of drafting a free license for it, but basically - if you’re not making an engine yourself, and you’re under $50k revenue per year - it’s free, actual license to follow hopefully sometime in the next 2 weeks.
Distribution is still via NPM: https://www.npmjs.com/package/@woosh/meep-engine
I update it fairly frequently
And it’s got a pretty good quality standard with > 4,500 unit tests
Last, but not least, the engine is, in fact, successfully used in production in a number of commercial projects, some pretty big ones that you would probably be surprised about
