Once a voxeler always a voxeler

That first red ball and then the voxelated red ball must have felt so satisfying.

Oh yes! Utilizing the hardware BVH system in conjunction with custom intersection shaders for the voxels is something that I haven't seen anyone do yet. Very cool. I am curious to see how it performs over time in comparison to, say, compute-shader ray marchers. Do you use any acceleration structure for the voxel traversal?

Yes I would like to know the same. I feel like it could be possible that the raytracing pipeline is too generalised and might not perform as well as the compute shader approach as a result. That being said, for raytracing specific hardware, the compute approach might not have access to a card's full resources.

Good to see you here! Currently I'm just marching through a flat 3D texture, but I plan to add a bunch of different accel structures (octree, DAG, etc.) and allow the users to pick them on a per-volume basis. I'm hoping this will allow for more fine-tuned optimization.

John Lin was absolutely doing HWRT for voxels - that was what started the project he showed on YT (first 4 videos I believe), and although he scrapped it for a while due to the AS build perf, he came back to it IIRC (for the final video or so).

@@GabeRundlett The AS build performance is definitely one of my largest concerns. So far it doesn't seem to be an issue but my test scenes have been quite small.

Hey Frozein! I love your videos! I am very excited to see what new progress you make on the new engine :) Will you do updates for terra toy? Or will you continue only focusing on this new engine? I know working in the same code space indefinitely is not very fun. But I would like to see more updates of terra toy! I think adding a few simple things (perhaps like falling sand or tiny creatures) while advertising the game on your channel could improve the revenue a lot?

I would like to make updates for Terra Toy, but school takes up so much of my time that I can only give enough attention to one project at a time. Maybe over the summer I'll work on it. I'm happy you're enjoying Terra Toy!

This looks rad. I've been watching voxel engine videos for a while but not many devs include animated voxel structures. As this is ray-traced, is it likely to perform well with extremely large voxel counts? I've been loving the Distant Horizons Minecraft mod which uses LODs for large worlds but I know some ray-traced engines are performant on large worlds by default

@frozein

2 ай бұрын

Implementing an LOD system will be pretty easy with the way I've designed the API , so I'll do that sometime in the future and see how far I can push the render distance.

Looks pretty smooth.

I would also be very very interested to see how you structured your project and code base.

@frozein

I'll cover the code structure in a future video. I would also like to open-source the project eventually but I'm waiting for it to mature a bit.

Crazy vid, so much work and learning to get to that stage. How long does it take for the bvh structure to be built?

I haven't done enough extensive testing, but for a very simple scene it seems to be ~1ms. I have to investigate more seriously though.

voxels, HELL yeah

"i know it doesn't look like a lot of progress" shut up, this is amazing progress for this being your second Vulkan project, be a little more proud of yourself!

Maybe also make it that each voxel can only have one color. This could also make shadows look pretty cool and unique. And you could maybe look into making the whole world just a single grid so that all animations are forced to look voxely / pixelated like in those old 2d jump and runs like mario

@frozein

2 ай бұрын

I'm definitely going to give each voxel it's own color, but I'm not going to force everything on the same grid. My last engine only had one grid and it proved very difficult to implement things like animations efficiently. I had to constantly remove and add new voxels, which was inefficient.

I think John Lin did something like this but as far as i know he is not developing his engine anymore. If you’re lucky you could find his source code and how he did his animations.

@@gooxey His source code is definitely not public unfortunately. But yes I also believe he used a similar approach, possibly also with Vulkan. Making an engine like his will require an insane amount of work.

Do you know about the pros and cons of using ray queries instead of the classic RT approach? AFAIK the former is said to perform much better on AMD hardware but I don't know the specifics of why it does that.

@frozein

2 ай бұрын

I assumed that ray queries would be slower since the driver has less room for optimization. But if it supposedly performs better on AMD I'll test it out eventually.

It always takes a lot of time for the backend with not a lot going on to the user.
