24 alternatives to SuperPaint – a fluid simulation painting app

I built this using Compose Multiplatform, with a C++ backend for the fluid simulation and rendering. Any feedback is welcome!

SuperPaint is a painting application that simulates fluid dynamics as users paint. Built with Compose Multiplatform for the interface and a C++ backend handling the fluid simulation and rendering, it offers a… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    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 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 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've made a drawing app based on my physical sketching practice, using fluid sim and some shader tricks to mimic watercolor-style ink washes. Best used on iPad or with a drawing tablet. The linked article shows how the core engine works, with plenty of little interactive demos. It was fun to make, sharing in hopes others find it fun too :)

    Hi all This has been my hobby project for quite a few years now It started as a small engine to serve as a sandbox to try out new 3d graphics ideas After adding many features through out the years and re-writing the entire engine a few times, this is the latest state It currently supports loading models with animations, textures, lights, shadow maps, normal maps, and some other goodies I've also recently added voxel raymarching as an alternative renderer, along with a fun physics simulation :)

    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…

    I was frustrated with laggy notebook stable diffusion demos. Plus they usually didn't have all the features I wanted (for example some of them only had inpainting and some only had img2img, so if I wanted both I had to repeatedly copy images between notebooks). So I made this desktop frontend which has much smoother performance than notebook alternatives and integrates image generation, inpainting and img2img into the same workflow. See a video demo here: https://user-images.githubusercontent.com/6392321/191858568-... Features include: * Can run locally or connect to a…

    Hey, I'm the co-founder of Magma and coded huge chunks of the product. My other co-founder Radek coded the collaborative drawing engine in Typescript with parts in Web Assembly and also using WebGL - that's why it has a native app feel. If you have an iPad or a Wacom tablet we support pressure sensitivity (enable Windows Ink if you have issues). We prepared 10 drawings that you can join. Beware that there is a 30 users (drawing at once) limit on each. You can easily create your own drawing and share the url with others to join. https://magm.ai/k36k…
