I've been building a low-level graphics abstraction that exposes a Vulkan/WebGPU-like API while targeting both Vulkan and WebGPU. The goal isn't to hide modern graphics APIs, but to let you write a renderer once and run it natively and in the browser with very minimal backend-specific code.

Made this for my son. :)

Two years on, and I'm still madly in love for how a discontinuated camera and TouchDesigner can turn a silly performance into an audio-reactive particle spectacle.

You can also access the project files [touchdesigner] through my Patreon page! - https://www.patreon.com/c/uisato

I'm experimenting with a few interactions based on this idea :)

I'd love to get other perspectives, what would be the first use case that comes to mind for you?

Little excerpts of me playing my chaotic pointcloud system, in which the particles are being audioreactive to the incoming audio signal in real-time. What do you guys think?

More experiments, project files, and tutorials, through my YouTube, Instagram, or Patreon.

A few more output example from this experimental multi-source video player designed for frame-accurate video switching, playback manipulation, and display/render interventions.

You can load multiple videos, decide exactly how many frames each source appears for, control how each source’s playhead behaves, insert black frames, switch between display modes, and save presets for different playback structures.

Videos, on the other hand, were generated on Uisato Studio [Kling v3 & Seedance 2.0 Video modes].

You can freely access it from Patreon, or the Store. Plus many more experiments, through Instagram, or YouTube.

Hope you all enjoy it! ♥

A solid example of an image-to-face workflow in Unreal Engine 5 using 3D AI generation as the starting point.

The base was generated with Hitem3D 2.1v, and the interesting part is that it already gets roughly 70–80% of the likeness before the manual production work starts.

After that, the result still needs the usual cleanup and refinement: sculpting, topology adjustment, grooming, texture work, and setup for the final UE5 / MetaHuman-style pipeline.

So it’s not really a one-click final result, but it shows where 3D AI generation is becoming genuinely useful: getting a strong likeness base fast, so the artist can spend more time polishing instead of starting completely from zero.

Pipeline:

• Source image / likeness reference
• 3D AI generation with Hi3D
• Likeness cleanup and sculpting
• Topology / MetaHuman-style workflow
• Grooming and texture refinement
• Final setup in UE5

For production, I think this kind of workflow makes the most sense right now: AI gives you the first strong base, and the artist pushes it into something actually usable.

After spending a lot of time on my renderer recently, I finally added tessellation support to my engine.

The implementation uses OpenGL tessellation control and tessellation evaluation shaders, and right now I’m using it primarily for terrain rendering with heightmaps. It was a fun feature to add because it pushed me into parts of the graphics pipeline that I hadn’t worked with much before.

hi, i revisit this page a lot. i was looking for museum based websites. i found this https://altcarbon.com/eli5/bengal-renaissance-project

what skills do people need to create this??

I am so torn about this desicion that I am reaching to you, kind strangers on the internet, for some advice :')

So I am doing my undergrad minor next year and there is this 6 credit graphics course I could be taking transfering to a different university. The topics it covers seem pretty solid. If you are curious to read I have left the syllabus here.

1. Geometric transformations and coordinate systems. Shipping geometry. Vertex processing. Composition of primitive and cut. Rasterització and interpolation. Processing fragments. Operations fragment. Upgrading the frame buffer.
2. Development of shaders Vertex shaders. Geometry Shaders. Fragment shaders. Language GLSL. API for developing shaders.
3. Interaction with 3D scenes Selection of objects. Manipulation of objects. Handling the navigation camera and the scene.
4. 2D Textures Texture space. Reverse Mapping. Generation, transformation, and interpolation of texture coordinates. Projective texture mapping. Sampled textures. Mipmapping. Samplers in GLSL.
5. Simulation of shadows Concepts. Umbra and penumbra. Properties. By projecting shadows on one or more plans. Shadow mapping.
6. Simulation of specular reflections Concepts. Direct Reflection (with virtual objects). Simulation with dynamic textures. Environment mapping
7. Simulation of transparent objects Introduction. Scattering. Refraction. Snell law. Critical angle. Fresnel equations. Alpha blending.
8. Global Illumination Figures basic radiometry. BSDF. General rendering equation. Mechanisms of transport of light. Classification of global illumination algorithms.
9. Ray-tracing Ray-tracing classic. Ambient occlusion
10. Ray-Intersection Geometry Algorithms-ray intersection geometry. Spatial Data Structures. Subdivision of space. Branch of the scene.

My problem is that, besides this 6 EC course and a computational geometry class, I have had to pick other 18 ECS (3-4 out of the 5 courses in total) that I am not interested in out of obligation, basically only to have the opportunity to take this one graphics course. To be honest, I am dreading having to do those 3 unrelated courses a bit, but I feel like it could be worth it just for the graphics course. I am relaively new to graphics, I discovered it recently and it became my absolutely favourite field in computer science so far. I have done some HLSL and GLSL with and I have started learning OpenGL over the summer to get more low-level, and I have found two courses I will be completing on graphics to continue learning, besides reading some of "real time rendering fourth edition":

I will also be following the university syllabus of a graphics course my friend is doing, out of his goodwill to share what he is learning. (this course: https://www.umu.se/en/education/syllabus/5dv179/)

On the other hand, I also have an offer to do a graphics-unrelated complete, coherent minor (bioinformatics and biotech) that I am very curious about, but this is more exploratory and out of the joy of learning computer science and trying this other field that interest me. I did not think I would ever have the chance to explore bioinformatics which is why this opprtunity feels so hard to miss, and I actually probably never will have the chance again due to my personal situation. In this minor, all the courses I will be doing sound fantastic and I am very excited about all of them, but I feel very anxious about picking this choice and letting go of the opprtunity of finally learning graphics in a formal manner during my bachelor, since this is the field I have liked the most in cs.

I wonder, for someone that already is more experienced in graphics than me. Is it possible to self learn these topics in graphics? Are the courses I intend to do for self-learning good or are they lacking compared to the minor course I would take? is this course (the one I would do in my minor formally), career- or thesis-changing, all things considered, compared to self-learning with the resources I listed? Is a formal class in graphics important for job opprotunities or would a portfoio with work matter more? As things stand now, I plan to do my thesis in computer graphics anyways, unless I really end up liking bioinformatics, and I don't know if this formal course could make a huge difference. I also have considered doing a masters in graphics as well since so far, it is the area of computer science I have enjoyed the most.
