Hi, thanks for uploading the video. We're trying to visualize a point cloud in imgui (it's for an academic paper). Your code would help us a lot - can it be found somewhere? Thanks.

Very nice to listen to. 33:32 good design.

Cool stuff, Dennis.

I still remember the thrill of mine!😊

Ωραίος! Παρόλο που το μηχανάκι σου δεν υποστηρίζει την οδήγηση σου το πας καλά. Στο 6:58 το έσωσες παρά τρίχα, το διαχειριστικες σωστα.!

Omg I just realized this vid is 12 years old. You definitely had future insight back then!

Not only a hobby but I can also feel passion. Looks great. Greetings 😊

Please correct me if I'm wrong, but intuitively I'm thinking you might already have a solution for fairly extreme deformations (like a character doing contortionist poses) and even without the need to be very conservative with the stretch factor or even avoiding it entirely without visible hole artifacts (along with avoiding stretching artifacts which are too noticeable) provided that your voxel models are high-resolution and filled in. The holes only seem to be an issue with a hollow surface, since a ray that misses a rotated voxel on the surface should still end up hitting one inside, and that doesn't seem to me like it'd create such noticeable artifacts unless the voxels are really large. That is to say, instead of only rasterizing the triangles making up the surface of the character to your voxel hierarchy, perform an additional precomputation step constructing your SVO which fills in the voxels making up the inside of the character's body (perhaps interpolating the material values of neighboring voxels and repeating until the entire character's body is filled in), turning it into a filled solid. For example, it is very challenging to deform the pixels making up a high-resolution outline of a triangle if we're going to do on the fly at render time per-pixel using a quadtree in a way analogous to raytracing without yielding gaps in the deformed outline or very visible stretching of it, but it doesn't seem so much so if the triangle is filled in and not just an outline. Maybe we'll notice a few aliasing artifacts around the triangle's edges if we zoom in close around the filled triangle's edges, but gaps should be eliminated since a ray that misses a rotated pixel will still hit one of its neighbors. Of course that results in way more voxels to store in the SVO, but that seems like the type of content that would lend itself reasonably well to SVDAG compression with lots of redundant octants.

Looks good!

Damn 11 years ago.

the wobbler at 8:57 can be by holding on to much with your hands i had when i started riding on mothers bike sort same power as mt 07 if arms are stiff the movement of the front wheel what is normal will go to the back wheel and make the bike shake i did it to

i like to push when riding but this was just not good in same places and a mt 07 with no suspension mods you neet to know that the bike will wobble so be make shure the wobble is before the corner. i have a 2015 mt 07 so i sort knoow what the wobble is

at 1:15 wy is the rider in front riding like that for that speed and lean angle you dont need to hang of i think they would take the corner better if they just stay neutrall when riding and focus more on how to take the corner

Nice!

with a full 10:24 minute view as we always give full views for our friends NEW and old.

great presentation and information , like 6 with full support-stay connected

Um... Dennis, what's your opinion on using cage deformations for skeletal animations of voxel models? I.e., splitting the model into connected cubical or tetrahedral volumes of appropriate size (each with its own octree), and animating the vertices of the resulting "cage" using any of the traditional techniques? Terribly sorry if you've already seen this comment. I'm just not sure if my first attempt to post it was actually successful "^_^

I'm relatively new to voxels. One thing I noticed is that people in the comment sections say it is difficult to create the models. Is that true? Let's assume I want to create a landscape with a forest on top of it. How would I go about creating it? Is there a blender-like tool out there?

try combining gigatextured triangles to a sparse voxel octree framebuffer and draw everything with breadth first in the octree, or just simple raster all or just simple testing raycast

you dont have to have boxy borders and surfaces, you can have a function determine if and how the surface is being hit, if you use functions as the surface representations, and the ocree as the ray-intersection resolving structure

have dynamic accelerated and created from source triangles to octree proxy representation, can be animated

octree is an acceleration structure for a triangle source data

So how the data structure looks like? It is not a 3D texture anymore? (Great work BTW!!)

Чувак, вернись пожалуйста к вокселям. У тебя же просто шикарно выходило

4:3 aspect ratio videos for the win. ;-D Not only full-sceen on iPad, but easier to watch on a 16:9/16:10 computer screen without consuming a whole screen (leaving room for a browser window, code editor, etc,)

Here because of the wax donation on Fstoppers you are awesome man.

I came here to see a modified MT 07!? where can i see that! :0) Your airbox removal looks awesome!

Hello! where did you buy the motorcycle plastics?

A voxel isn't necessarily a cube, though a regular grid will typically subdivide into cuboid volumes. So even if it is practically the most common and obvious case, maybe there are many breakthroughs to be made if we can imagine voxels in a higher level than just "cubes"

Good stuff.

You actually can rotate entire models (by model, I mean a tree) in world space. Rotating individual parts like limbs within a single model (in local space) get a bit tricky, however.

Wow- you rock!

I've come to look at what a 169kg MT-07 looks like. Have you done any more weight savings since? My ABS version is 175kg as I've only changed the exhaust, battery and swapped to aluminium bolts.

Mr. Kozak

This was heavily used in DOOM(2016)

so let me get this straight.....each box has 8 children and each child has the potential to each have 8 children, and you just choose to render that generation or that child?

Is it true that you can't rotate a Voxel? Can't you have several independent Octrees attached to the vertices of polygons?

"Voxels are little cubes. Nothing more, nothing less". I can't believe you're starting off an "in-depth explaination" with something so blatantly factually wrong.

Question why can't I just have the octree Interpolate between two similar but diffrent octrees?

Voxels vs polygons are like bitmap vs vector. How can it be memory efficient, when this is the most limited factor? If you take the 2d star example. How many bits do you need to save such a shape as vector graphic? You can't have unlimited detail, because you have not unlimited memory... and even if you save only the surface by LTC or SVO, you need the memory for the surface. So double the resolution will quad to oct your memory. I am still not sure, wether voxels are the future, like some genius predict us. I am excited how much memory a Quake 3 level would take, if you use voxels instead of polygons in atomontage resolution.

Couldn't you just use multiple octrees and rotate them by raymarching on a distance field?

Hi! How do you render the voxels? Are those raycasted, or made by tiny triangles? Thanks!

This is great. Didn't know it's possible. P.S: i wanna punch every person who says "OMFG!!!!!! have you seen Euclidean?". Ye, i've seen. Total bullshit.

For those wondering, this is what is used to make AtomontageEngine (obvious since featured in this video ) and euclideon possible.

You determine the center point of every voxel. Does it mean, that it is rather a pointcloud then? Becouse you need the position of the voxels individually? Thanks!

Thank you very much for sharing your knowledge with us :)

I woner what happens if you will try to capture a mirror. :D

I want a voxel animation software now!
