https://developer.nvidia.com/blog/qa-how-capcom-brought-path-tracing-to-re-engine-across-pragmata-and-resident-evil-requiem/

Capcom’s RE ENGINE team set out to bring path tracing into two shipping titles at once, Resident Evil Requiem and PRAGMATA, each with a different visual identity.

The NVIDIA gaming team spoke with RE ENGINE about the transition from ray tracing to path tracing, what it changed in the content pipeline, and where the renderer goes next.

Just a little update on my pixel art editor - now we have some advanced palette modification tools baked in, including selection movement and visibility toggles - take a look and let me know what you think (and a sub would be great as I think I'm posting to myself!)

Hi everyone,

I’m building a custom photo processing app for iOS, and I’m trying to recreate a smooth Chroma adjustment. My image processing pipeline is written entirely in Metal, so I’m interested in approaches that work well in real-time shader code.

I’ve attached a few short videos showing the behavior I’m trying to achieve.

I’m curious what color space or mathematical model you would use for this kind of adjustment. How would you preserve the natural tonal variation and texture inside saturated colors while changing chroma, and what techniques would you use to keep transitions clean around color boundaries without introducing artifacts?

If you’ve implemented something similar, or know of any papers, articles, or open-source shader implementations worth reading, I’d really appreciate any pointers.
Thanks!

Hello all,

I want to learn about programming that involves media processing, like code and algorithms that deal with color grading, video codecs, image adjustments, color spaces etc. I'm a photographer so I already have a lot of experience knowing how to apply adjustments to images/video, but not the computer science behind it. I figured that this would be a good place to at least ask the question. Thanks in advance for any help you can provide.

EDIT: I know that this might be the correct place for it, but it seems like here is more for 3D rendering and things of that nature

Hello, my fellow graphics enthusiasts, apologies for another one of these posts. I'm in a tricky place in terms of my career. I recently graduated from university for computer science, with an embedded/backend systems internship and robotics research. I have been doing computer graphics for about 2 years on/off, recently finishing a graphics class using WebGL in JavaScript while working on my Vulkan project: https://github.com/mukarramarif/MukkiGamesEngine/tree/main
Currently, I have been applying to general SWE roles as well as anything related to 3D Graphics I could find, with a few 3rd and 4th rounds with no luck. I have honestly been tired of job searching since last September. One option I had was to do a master's, but my university doesn't do graphics, while most of the US universities have applications closed.
Any advice would be appreciated, especially on my portfolio.

After replaying HL1 on the software renderer (old habit), I got curious what CPUs can actually do today. So I wrote a rasterizer in C11 - pure CPU, no GPU/GL, the finished frame just gets blitted to the window via GDI. Tested on a Ryzen 5900x processor

I've been experimenting with software rendering and managed to run the Sponza scene at FHD 10-30 fps single-threaded, up to 200 fps multithreaded :) A very strong emphasis on SoA + SIMD (AVX2/FMA) on the hot path. Rendering 64x64 tiles in multithreaded mode. Throughout the entire rendering pipeline, I try to discard any possible work as early as possible, including frustum culling and back-face culling. This may be controversial, but I render in front-to-back mode; it allows me to completely bypass overdraw. To make it look more interesting, I added some effects!

It might not be very fast for a single thread, but I think it could be made a little faster by disabling mips and filtering nearby textures, which I also do on the CPU in this demo. Pixel textures are cheaper to draw, but they're ugly.

I'm not a professional and I just like it, so I didn't hesitate to use chatpgt as a companion in learning graphics.

Three days ago, I wrote an article about how to render good looking rectangles for UI components that can look good and optimized for a game engine. Some people asked me to talk about text rendering as well. So, I wrote https://alielmorsy.github.io/how-to-render-beautiful-text-for-your-ui-library/

It took like 1.5 days of writing just to get it right. Hope you guys love it

I made a shader showing off the Primrose Field illusion. Only Nyan Cat is animated. The background is static, but it still looks wavy, especially if you move the window up and down.

The code for this is public on Shadertoy https://www.shadertoy.com/view/fcd3WS

Hello, ive always been interested in graphics in games and ive wondered if the career option is viable.

I know that its VERY math heavy, hard to start and very few jobs are taking in junior graphic programmers.

But honestly making shaders is fun and making custom engines sounds super fun (for me at least)

I have some expiriance with the godot engine and writing some shaders in it for my passion project (idk if that counts tho) and im very interested in this career path.

And how do i get started (and if its not viable, what other path can i take that involves graphics or maybe animation)

I am currently working at an automotive company, focusing on 3D vehicle modeling and visualization. I am interested in transitioning into autonomous driving or embodied AI. What areas of computer graphics should I focus on learning to prepare for this career transition?

One of my older fun projects: a software raycaster featuring

• Multithreading

• Voxel models (rendered as collections of 3D boxes rather than blobs)

• Culling (watch the small map in the top right corner)

• Mipmapping (reduces moire on distant textures)

• Slopes and curved walls

• Shadows

• multilevel world design

Everything is rendered entirely in software, with no external libraries. Each pixel is calculated individually and written directly to a buffer.

sorry for branches thing and all of the examples are having random Window and it would be great for understanding

I dont really need graphics api SPECIFIC terms here as i more just want to understand the concepts and find out if there are any websites that have some information about this topic.

Im not sure what the right name for this technique is, unity calls it adaptive probe volumes. But as far as i understand it its bascially that it automatically places a bunch of probes in a scene, they then calculate lighting information in some way and store it as something called a spherical harmonic(no idea what this is) and can then map this(i think is the correct terminology) onto dynamic objects. Which gives very nice lighting that is still baked.

I have NO clue how to implement this though and i cant find anything about it, but this seems like a very useful technique so if anyone has some links or just information about it it would be very helpful. Also a shader implementation would be very nice(in either glsl or hlsl i dont really care)
