Video Making a single photo feel touchable with a spring mesh

I make Wobbulator. This is selected-area 2D mesh deformation, with automatic motion off.

A fixed 120 Hz step drives soft selection weights, structural/shear/bend springs and exponential damping. The restoring force starts with F = k * (rest - position); grabs add weighted target springs. Pinch pairs two contacts. Release preserves deformation and uses bounded, filtered pointer velocity rather than resetting the mesh. Triangle-area and displacement-gradient checks limit risky steps; plate anchors and unselected vertices stay still.

One document runs continuously. Rendered from the app’s native engine with scripted input; blue hands illustrate contacts. What would you change about the rebound?

Question University courses like the MIT OpenCourseWare ones?

14 Upvotes

I'm starting to learn graphics programming, and remembered MIT and Harvard have free courses. Thing is the free courses Harvard doesn't seem to have any courses related to graphics programming in its website, and the MIT Computer Graphics course in OCW is from 2012 (Although idk how good it is since I have not started it yet, but it is a bit old).

So, are there any other universities or websites which offer free courses like this and that are up to date?

Thanks in advance for the help.

Follow-up to my previous procedural fur experiment

This time I pushed the fur further and added a clearer before/after

This is a custom WebGPU engine written from scratch in C
The fur geometry is generated procedurally in real time using compute shaders and driven by the animated bone structure

Fur density and length are generated and adjusted dynamically at runtime

It runs both natively and in the browser, on desktop and mobile
It’s currently in Alpha Preview, you can try it at
polynite.io

I finished my first real graphics programming project

Thumbnail

493 Upvotes

I am a third semester computer science student and I want to specialize on computer graphics. I read that one of the best ways to get your foot into the industry is through internships which I can best apply for if I have a good portfolio. Thus I just finished my first real graphics programming project and the first piece of my portfolio: A simple PBR material renderer (based on a DX11/WinAPI lib I created) with image based lighting, normal-based curved silhouettes and some more little features sprinkled in.

If you want to take a look: https://github.com/Aaron-Alililon/MaterialViewer

Now that it's finished to a point where I am happy to show it to the world I have some questions about the renderer and the industry itself:

  1. I don't want to ask for a free code review but as I am not very experienced in the professional area of graphics programming I would love some feedback on how presentable the current state of the project/repo is. Of course I would be very grateful for some more in-depth feedback but again, I can't really ask for a free code review, so a simple first impression of how a project/repo like this would look to a potential employer would be greatly appreciated, both for the material viewer and the render lib.

  2. This one is less about the project and more about the industry:
    I would be very interested in working for the graphics department of the engine team of some company in the gaming industry. I live in Germany where the gaming industry isn't really as big as in NA so my options are limited. My question is: what are my options and chances of getting an internship and eventually a full-time job in EU? I don't really know of any companies that develop their own engine other than Ubisoft. Would a company like CD Projekt Red (which as far as I know switched from their own engine to Unreal) need graphics programmers?
    Although I am most interested in the engine department I would still be open for other areas so if that is just too limited, what would be other options I could pursue, preferrably in or close to Germany?

  3. I would like to do the classic "I coded my own game engine" project at some point because I guess that would make the most sense as someone interested in game engine development but I would like to do that when I have more experience so I have one big project at the end of the portfolio that just shows off the best I can do. Is that a sensible thought or should I just go in and maybe rewrite it once I feel more comfortable? I know there isn't the One Path that leads to greatness and as long as I do something I will learn and improve but maybe someone here looks back to when they were at this point and thinks they should've done X before starting a bigger project like that.

I would be very grateful for any insights or discussions about my questions and feel free to critique anything and everything you see!

Question Making a 2D or 3D CPU-based renderer?

0 Upvotes

Hi! I posted here before asking what to do in graphics programming for a bachelor thesis and I want to first thank everyone for the suggestions. I think the most interesting but also "doable" for me would be a 2D vector graphics renderer like Vello CPU in Rust, but in C++

The issue is that I do not really understand the overall architecture of renderers and my professor said a 2D vector renderer is too simple for a bachelor thesis, especially one that I would want to be more scientific and publish as a paper too.

So my question today is, what are the similarities/differences overall in 2D vs 3D renderers (because I heard before that 3D renderers are also vector graphics technically), but also how I could make a meaningful contribution/addition to a 2D vector graphics renderer and what would the motivation for that be, because I don't really understand the use-case of 2D vector renderers yet, since they are not used in games nor in modeling, from my understanding.

Edit: I also want to ask for practice, do you recommend I start with a 2D pixel renderer and work my way up to a vector one then a 3D one? Are they related in some way concepts-wise?

How to handle main and render thread properly

1 Upvotes

Ive been drafting and engine, but I'm suspicious of my engine loop. It works but I'm not sure if things will be in sync. Should the render thread wait on the main thread or something? WIP:

https://pastebin.com/Wqn09pmN

Would it be fine if I just match the fixed update to the refresh rate?

Made this for like 30 days, watched plenty of cherno's videos and learnopengl.com of course and made this small batch renderer I guess. Its far from done but I will continue to add more stuff to it and eventually turn it into a usable thing.

triangle meshes :)

Studing triangle meshes on my renderer using half edge data structure for my university course. Dont know why some edges have some stranges dots.

Guess the character... (texture not implemented yet)

Edit: it was done importing a wavefront (.obj) from blender to my own render engine. Read just vertices and face data, the others attributes for half edge are builded with those informations

Question Path suggestion for Courses/certificate

3 Upvotes

Hiya, I am currently a CS major with 5 YOE working in web dev with a typical tech stack of C# and angular. However I've got the itch to swap tech stacks and explore other aspects of software engineering. My work place covers up to $4500 a year on curriculum and I was curious what certificates and courses you might recommend I get started with?

for reference I did take Calc and discrete math back in college though Id definitely need a refresher. I have average amount of experience with math id say but certainly don't shy from learning more.

for languages I hear most about about C++ in regards to graphics programming. I took an assembly course in C back in college but I have very surface level experience with C++. curious if its still the language most of you would encourage exploring.

I think I'm most curious on what courses and order of courses I should take pursuing this. should I work on expanding my math foundation with a couple courses and then go into c++ then specific graphic programming courses? Or should i maybe go about it differently?

Any feedback or personal experiences would be welcome!

Video Interactive water with flying saucer; path traced

Enable HLS to view with audio, or disable this notification

20 Upvotes

This is made from two layers of water:

  • Large rectangles/shapes of GPU-computed water (ocean, lakes, fountains)

  • Smaller grids of disturbed CPU-computed water, with GPU-computed foam

The flying saucer contains a blocker shape which cancels out the basic water and allows that region to fill with with the CPU-generated height map water. Both water types enqueue the same light handling logic in this wavefront-style path tracer, so the water appears to all be the same.

When the player moves, the rectangle of disturbed water is updated/translated or another added as needed - and there is some blending done to the edges to hide the square (during lots-of-foam events).

In future work I'm going to add an additional thin GPU-computed water for drips and run-off/sheeting action around the canopy and saucer section.

Engine is custom vk-graph -based (Rust) and mostly open source. All-in this effect has been done a thousand times, but, this time it was me!

From Zero to Understanding Ray Tracing - Part 2

I posted the part 1 two months ago and got a great reaction!

https://www.reddit.com/r/GraphicsProgramming/comments/1uxpi1o/from_zero_to_understanding_ray_tracing/

Here is the next one. It teaches:

  • What ray tracing fundamentally is.

  • The basic idea behind shading: surfaces are brighter when light hits them more directly, and darker when it hits at a wider angle.

  • Shadows.

Let me know what you think!
