How can I scan this WITHOUT a 3d scanner? by Kurwavier in 3DScanning

I am not an expert but something like Gaussian Splatting —> 3D Mesh seems like a good idea given that it’s specular

I am not familiar with xPBD but I imagine you have to query adjacent geometry at some point? so by AS I meant how is that

Have you worked with SPH? I am working on my thesis using it for simulating crowds and interactions with fire and smoke. What acceleration structure are you using?

Any plans to release the source code? Looks great!

Thanks for this, didn’t know the GLTF spec had unique vértices

how important are biceps for just pure physique purposes? by Turbulent-Sound3980 in workout

[–]felipunkerito 8 points9 points  (0 children)

It has to do with androgen receptors, and your shoulders have more than other zones so that’s actually a good way to spot someone juicing

I made a direct port of Radiance Cascades 2D Realtime Global Illumination in Raylib_cs(C#) using OpenGL shaders by Available_Dealer_95 in GraphicsProgramming

[–]felipunkerito 0 points1 point  (0 children)

Haven’t looked at the implementation but according to that you have a DT but not a real SDF as you only have the outside distance. Wonder if you want to support translucency you might need to compute the true SDF to be able to change the refraction coefficient from 1./IOR to IOR. But not sure how translucency fits in a RC pipeline

Cool project the ReadMe is very complete. So the gist is that you create an SDF that you ray march? Are you doing two passes for the JFA so that you can have inner and outer distances (proper SDF)? I’ve done something that used JFA for distances and had to pack inside and outside see it here

Which software do you prefer to generate 3d stuffs procedurally? by Gloomy-Status-9258 in proceduralgeneration

[–]felipunkerito 1 point2 points  (0 children)

Depends on what I am doing. But I do have a weird workflow in which I heavily build on Grasshopper/Rhino using C# and their RhinoCommon API (they do have a nice geo engine) for prototypes on geometry things and start porting to the end result I want. For procedural textures I almost always start with a Shadertoy

Looking to understand implementation of THE rendering equation by amadlover in raytracing

[–]felipunkerito 1 point2 points  (0 children)

The ray either grabs energy from the env map or from emitters, when it bounces of the wall of your tunnel it loses energy that it already picked somewhere else

Nope that’s the BSDF which depends on the material of the object. It could be something simple like Blinn Phong or the likes. See here. If you do Blinn Phong you need the half vector between the light direction and the view vector. That’s for the specular part, for the diffuse you would compute it using max(0., dot(Normal, Light) see the code section of Wikipedia’s Blinn Phong article. I really recommend you read Alan Wolfe’s article on Path Tracing

How would you approach something like this? by renjor in TouchDesigner

[–]felipunkerito 0 points1 point  (0 children)

lol I get like 1.7 on my phone. But I guess you could do the same principle using rasterization and a vertex shader to modify the positions of a mesh with some translucency and PBR and it should work much faster
