Pieced my custom CPU-side fluid simulator together with the WebGPU implicit surface generator, and now we've got chocolate shakes 🙂. #webgpu #computergraphics #indiegamedev #physics #js

@wrennly_dev @XorDev I leveraged GPU compute by using the most modern functionality. Special care was also taken that I use just the right numbers of threads needed to reconstruct the 100s of 1000s of triangles/frame. Also made sure the surface recon algorithm I used fits well with my WGSL workflow.

@ThatRenderMan @XorDev surface recon in real time on gpu sounds wild, how did you handle the isosurface marching without killing performance?

Released only 1 month ago! Growth has been great to see. Got some exciting plans in the works

@XorDev It was just yesterday that I remembered the time when there was this challenge for CG devs to write a raytracer small enough to fit a business card. Such vibes are what piqued the interest in CG for others. Wonder if that kind of spirit still exist in the CG industry nowadays.

If I have disposable income, I want to wrap my car in shader code

@wrennly_dev @XorDev @wrennly_dev This link is to a WebGPU-based Lagrangian fluid demo I wrote, with surface reconstruction all in real-time, thanks to the GPU-sided computations for fluid and its isosurface generation. Better you use modern browser (especially Firefox’s); …e-ayeko-webgpu-fluid-mesh.netlify.app

@ThatRenderMan @XorDev yep you can definitely write wgsl directly! i hit some weird type errors at first but just treating it like rust helped. curious what kind of physics are you simulating? 🚀

@wrennly_dev @XorDev @wrennly_dev I research and implement various methods used for simulating physics dynamics in games and the animated film industry, especially those used in simulating Fluid Dynamics; including purely Lagrangian methods, Eulerian, and Hybrid approaches.

Perspective Projection? Length, angle, area, shape- majority of quantities in the Euclidean geometry are not preserved after projection (which images went through). They often appear modified. The only thing preserved after projection is that straight lines remain straight.

@Olafarevictor1 It was a start 🙂

@ThatRenderMan I did but the pacing was slow😅

Yeah...... I got this

@XorDev Would be nice to write a water shader and hear the sound of rushing water waves. Fire and hear burn. Cloud and hear it rumble. Now would it be synthetic?

Who wants audio reactivity in FragCoord?

@Luckyballa Just don’t have the means yet- I wish to initiate a medium that teaches CG methods (physics dynamics & rendering) by presenting the theories & math behind them in an interesting and intuitive manner. Just to save newbies from the frustrations I experienced during my novice days.

Imagine if all computer graphics papers were published like this 🥹

@Luckyballa Still hold the strong opinion that early CG papers, for both physics sim and rendering, were more easier to read & digest, even if u don’t have a fancy CS degree. But it’s extremely difficult nowadays, as the papers appear too condensed & abstract to be digested by just any one.

@Infinity__Live @RhonddaBryant Don’t really know what this is all about. Not sure if I know the woman, even. Doesn’t mean others around here don’t, though. Care to fill me in?

@RhonddaBryant @ThatRenderMan - Nigeria side working as well as the British side ?

Taking UK–Nigeria trade to the next level. A great meeting this morning with my counterpart Jumoke Oduwole. A fast-growing £8.1bn trading relationship with room to grow 🇬🇧🇳🇬

Sometimes ago, I experimented with shader arts. Signed up for @XorDev FragCoord (excellent work by the way) recently and I wrote a little shader I call ‘Ring Of Flames.’ Decided to make a content out of it. Link to the shader on FragCoord in comment.

@XorDev Alright, then. I guess we’ll see.

@ThatRenderMan Not possible. I want to look into the viability of supporting multiple shading languages

@cotterzz @Infinity__Live @XorDev Building on what @Infinity__Live has said, the fluid surface is made up of 100s of thousands of tris being created per frame by the GPU through a compute shader. Vertex shaders can not do this. They can only manipulate existing geometry’s vertices (created on cpu) on the GPU.

@Infinity__Live @XorDev @ThatRenderMan The CPU has to provide the starting vertex buffer, but you can still manipulate it on the GPU Maybe not as flexible as compute (no storage buffers) but the vertex shader can do a lot, eg: vertexshaderart.com

The syntax highlighter is smarter, finding licenses and with clickable usernames/links

@XorDev Thanks @Infinity__Live for recommendation.

@XorDev Here is a physically-based fluid simulation of thousands of fluid particles used to generate iso-mesh (fluid surface) in the browser I wrote using WebGPU and WGSL: advance-software.com/misc/leke_webg…
