24 alternatives to Krita RGBA Tech – Bringing Realistic Metal to Life in Open-Source Art

Krita's v4.2+ RGBA brushtips let you paint with dimensionality, and it's a technology that Photoshop doesn't have (≖‿ゝ≖) It lets the creator do things like emulating light direction, making brushstrokes look 3D. I used them to make a set of metallic brushes. If there are any FOSS artists around, feel free to test them out. (p.s. Yes, I am learning Github so I probably made repository mistakes - apologies in advance lol)

Krita RGBA Tech is a collection of metallic brushes designed for Krita v4.2 and later, leveraging RGBA brushtips to create dimensionally realistic brushstrokes. The brushes emulate light direction and three-dimensional… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hey HN! I want to show my new open-source project ArtistAssistApp. ArtistAssistApp - the web app to paint better with ease. Tools for realistic color mixing based on real paints, tonal value drawing, simplified sketching, and more. Import your own photos, select any desired color directly from the image, and learn how to mix it with your paints. The web app provides a step-by-step guide on how to precisely mix that color using your own paints using atomic or optical mixing. Atomic mixing is the physical mixing of colors together, while optical mixing is the result of placing a transparent…

    Hey HN! We're Ben and Izak, founders of Repaint (YC S23). Repaint is like Figma, but for creating real websites. It has panning, zooming, and dragging elements around. The settings closely follow html/css. We think an open canvas is a big improvement over other website builders. Everything is easier: styling, consistency, responsiveness… But making it work was hard! We thought HN would appreciate the tech behind it: - A custom WebGL rendering engine (w/text, shadows, blurs, gradients, & opacity groups) - A partial implementation of the css spec - A custom text editor & text shaper…

    For the past three years I've been building what I hope will be the next Blender, tackling the lack of any good 2D design or image editing tools outside the Adobe monopoly. This was our first year participating in Google Summer of Code and this Q3 update includes the big payoff from that, covering the most progress we've made so far as a project. If you're a Rust dev, consider getting involved as we apply for the next GSoC in the new year— you could be our intern next summer :) Q3 progress report: https://graphite.rs/blog/graphite-progress-report-q3-2024/

    Hey all, You've probably seen projects that add objects to an image from a style or text prompt, like InteriorAI (levelsio) and Adobe Firefly. The prevalent issue with these diffusion-based inpainting approaches is that they don't yet have great conditioning on lighting, perspective, and structure. You'll often get incorrect or generic shadows; warped-looking objects; and distorted backgrounds. What is Fill 3D? Fill 3D is an exploration on doing generative fill in 3D to render ultra-realistic results that harmonize with the background image, using industry-standard path tracing, akin to…

    I'm enthralled with using pen plotters to make generative art. Last August at SIGGRAPH, I built an interactive experience for others to see how code can be used to make visual art. The linked blog post is my trials and tribulations of linking a MIDI controller to one of these algorithms and sending its output to a plotter, so that people may witness the end-to-end experience.

Demo here: https://www.youtube.com/watch?v=maWR7dDf4SE Although it will be improving, the codebase has a few issues The Good - ability to multitask within krita while generating images - uses a queue so you can queue up multiple images without waiting for your other batches to come back - no need for a webserver (uses sockets to communicate) - clean code - active development (i want to use this tool myself) - uses…

    Creating high-quality scientific figures can be time-consuming and challenging, even though sketching ideas on paper is relatively easy. Furthermore, recreating existing figures that are not stored in formats preserving semantic information is equally complex. To tackle this problem, we introduce DeTikZify, a novel multimodal language model that automatically synthesizes scientific figures as semantics-preserving TikZ graphics programs based on sketches and existing figures. We also introduce a Monte Carlo Tree Search-based inference algorithm that enables DeTikZify to iteratively refine its…
