Not only some people program whole games in fragments shaders (like Quakes or others), but also some simulate whole computers or programming language interpreters ! For now there are 9 of them: Apple I emulator ( ROM + memory editor + BASIC language ). More about Apple_I computer. Turing Machine Interpreter . More about Turing Machine. … Continue reading Simulated computers & languages| shadertoy – unofficial
In their shadertoys, programmers have to handle everything, and redo everything from scratch every time. For repetitive basic utilitary features like GUI or font display it can thus be very boring, so that many just don’t embed any GUI and users have to tweak defines. Fortunately, various community members have publish useful base elements that … Continue reading Widgets & GUI toolkits (and more)| shadertoy – unofficial
Sometime you need to access Shadertoy built-in media (texture, video, music…) out of Shadertoy (e.g., if porting your shader to desktop, or writing a paper or a blogpost about your shader). Here they are: 2D textures: NB: font generator (CC0) by Octavio Good Cubemaps: Volumes: Grey noise3D RGBA noise3D Videos: Musics: 8 bit mentality … Continue reading Shadertoy media files| shadertoy – unofficial
Many people start writing GLSL shaders as they would write C/C++ programs, not accounting for the fact that shaders are massively parallel computing + GLSL language offers many useful goodies such as vector ops and more. Or, not knowing how to deal with some basic issues, many people copy-paste very ugly or unadapted code designs, … Continue reading Programming tricks in Shadertoy / GLSL| shadertoy – unofficial
Optimizing GPU code, as for parallel programming (but worse), is difficult and unintuitive. Several tools can help in this task. Alas, none work in webGL, only on desktop. But you can easily port y…| shadertoy - unofficial
