Mi primer Hello World de los triangulos, un rasterizer 3d de triangulos pero en software. Es el primer paso al engine 3d por software. A modo didactico solo dibujar con alambres, luego ver como mapear la textura, por ultimo arrays, brushes, lights, etc Por ahi un loader .bsp para no escribir tantos triangulos 🥵 . Para animar se usa "matriz de transformacion" (rotar, escalar, mover,skew,flip) despues procedimiento para pasar 3d a 2d el "draw affine" del quake1, lo ideal seria "draw perspective". #gamedev #sdl #gfx

Went to go remove any games from my wishlist, only to realize I don't have a single one on there. No , no , no . Turns out I haven't really been microsoft's main target for a while. I don't use . Never used . Don't write programs with , I use Vulkan and and . Don't use . Never used . Don't use an on my PC, I use an 8bitdo controller. Don't use . I am disconnected from them.

Built a simple 2D solar system simulator in C++ with SDL3 — still very much a WIP, but happy with how it’s coming along!

Ok I managed to make #SDL3 #Gfx ImageFilters work... but only by disabling MMX optimizations. Looked at the source and, well, this is a not very used part of SDL_gfx.

I think its possible to remove those optimizations, computers are pretty fast nowadays.

The current library is this one
github.com/sabdul-khabir/SDL3_

It kinda also needs a bunch o QoL features (use floats, bools, clean up, etc), to match SDL3... maybe I can roll up my sleeves and try to fix this for my #sdl #vala binding.

#gamedev

I got a #gamedev #sdl question. Specifically for #SDL_gfx.

Does anybody know of a proper sample for the MMX image filters functions?

I know the tests exists, but these seem to only to affect small custom-made arrays.

But, I think that you should be definitely be applying these to surface pixel data, right?

I've been trying to make a sample in vala but keeps crashing. I plan to make it work in C to truly understand it. But wanted to ask if anybody knows about a sample before doing that.

Despite my body aching and being sleepy all over, I managed to work out a small #sdl3 #Vala bindings update.

I have now implemented the SDL3_gfx library! This is a special small library that implements:

* Some special primitive drawing routines, like circles, pies, beziers, etc.
* A simple framerate manager.
* Some algorithm filters (I still need to understand how these work to make proper samples).

But in any case there are samples for framerate and primitives. Enjoy!

What is the proper way of ensuring non-exclusive borderless fullscreen on Windows + OpenGL?

Using windowed + borderless flags in SDL still results in exclusive fullscreen:

How do most games implement this sanely?

Возможности реагирования на инциденты информационной безопасности с помощью KSC Open API

Команда STEP LOGIC разработала новый фреймворк противодействия инцидентам информационной безопасности – адаптивные действия, благодаря которым аналитики центров кибербезопасности (SOC) смогут быстрее принимать меры по сдерживанию и ликвидации последствий инцидентов непосредственно через единый графический интерфейс продукта STEP Security Data Lake. Автор использовал этот фреймворк для взаимодействия через Kaspersky Security Center Open API и рассказывает об этом в статье.

So the source code is now available. This game was ported for there is even a version.)) And only is left without it. Windows Smartphone owners say that it works quite well, these devices have a 176x220 display and a very weak processor)) We are ready to talk about another port for N-GAGE. :fatpikachu:

Actualización: DOSBox AGA y RTG

DOSBox, el renombrado emulador de MS-DOS, se actualiza en su port para Amiga gracias al trabajo del desarrollador NovaCoder. Dos nuevas versiones, optimizadas para AGA y RTG, permiten a los usuarios disfrutar de la vasta librería de juegos y aplicaciones de PC directamente en sus sistemas.

La versión DOSBox AGA v0.74.013 está diseñada para Amigas equipadas con el chipset AGA y un procesador 68060 rápido. Requiere AHI (versión 4.18 recomendada) y ROMS 3.1. Ofrece un port SDL nativo para AGA, soporte MIDI y sonido AHI, así como modos de pantalla completa y ventana.

Por otro lado, DOSBox RTG v0.74.023 se dirige a Amigas con tarjetas gráficas RTG y un procesador 68040 (se recomienda un 68060). Al igual que la versión AGA, necesita AHI 4.18 y ROMS 3.1. Sus características incluyen un port SDL optimizado para RTG, soporte MIDI, sonido AHI y las opciones de visualización a pantalla completa o en ventana.

I'm loving the smooth trails this "ribbon" renderer creates! It dynamically builds a mesh from the ball's past positions. The faster it moves, the more opaque the trail becomes. Plus, it keeps spacing even unless there's a sharp turn!
