Show HN: HORenderer3: A C++ software renderer implementing OpenGL 3.3 pipeline Hi everyone, I wanted to share a personal project I've been working on: a GL-like 3D software renderer inspired by the OpenGL 3.3 Core Specification. The main goal was to better understand GPU behavior and rendering pipelines by building a virtual GPU layer entirely in software. This includes VRAM-backed resource handling, pipeline state management, and shader execution flow. The project also exposes an OpenGL-style API and driver layer based on the official OpenGL Registry headers, allowing rendering code to be written in a way that closely resembles OpenGL usage. I'd really appreciate any feedback. https://ift.tt/7RMuEK3 January 18, 2026 at 12:34AM

Show HN: Guish – A GUI for constructing and executing Unix pipelines https://ift.tt/HrXz5ub

Show HN: Guish – A GUI for constructing and executing Unix pipelines guish is a dynamic data pipeline UI that allows users to visually construct and execute complex command-line pipelines. It provides an intuitive interface for chaining together various Unix commands and custom plugins, making it easier to build and understand data processing workflows. It also features optional LLM support for updating pipelines with a natural language interface. https://ift.tt/2lsA0r5 August 2, 2024 at 10:00PM

Launch HN: PillarPlus (YC W20) – Automatically create construction blueprints https://ift.tt/2yet5m3

Launch HN: PillarPlus (YC W20) – Automatically create construction blueprints Hey HN, we’re Naman and Rushil, founders of PillarPlus ( https://ift.tt/3dHyOBg ). We build software to automate the creation of construction blueprints. Specifically, our software generates engineering blueprints for air conditioning, ducting, fire, electrical, and plumbing services over the floor plan of the building. MEP (Mechanical, Electrical, and Plumbing) designs are a set of 15 technical drawings. We got started in India and are currently operating there, but MEP is standard enough that the software can apply to Western markets also, given that we have incorporated international building codes. Architects and contractors hire consultants, who still design the building manually. Complete dependence on human effort results in a process that is slow, error-prone and unreliable. Also, the number of consultants is limited resulting in higher fees, long delivery times and difficulty accessing the services. ...
