flat varyings
inferring data texture size
integer textures (require explicit uniform declaration for now)

2023-11-15

devicePixelRatio handling in examples
(LargeLenia)[https://google.github.io/swissgl/#LargeLenia] demo)

2023-11-12

Inc can be a list of strings (to avoid long string concatenations every frame)
Removed hooks mechanism (using wrapper functions instead)

2023-09-12

Async texture fetch support (see (FancyLenia)[https://google.github.io/swissgl/#FancyLenia] demo)

2023-09-07

Samplers support (see TextureSamplers demo)

2023-08-25

varying's can be declared in-place in VP arguments
glsl.adjustCanvas() should be explicitly called in glsl.loop() callback

2023-08-11

glsl.adjustCanvas() helper
glsl.loop() helper
tiny.html minimalistic example

2023-08-05

Physarum3d demo

2023-07-11

(breaking) Default texture filtering is now nearest. This is a workaround for iOS devices, where texelFetch stopped working for float32 textures when filtering is linear.

2023-06-19

(breaking) VOut -> VPos

2023-06-15

readSync method for fetching textures to CPU

Texture arrays (layern target parameter)
DeferredShading example

2023-03-19

(breaking) removed code argument. Shader is passed through VP, FP and Inc parameters. Shortcut syntax can be used in VP and FP independently.
(breaking) vertex() function now returns void, output should be written into vec4 VPos variable. fragment() output now should be stored in vec4 FOut.
(breaking) tag attribute it now obligatory for newly created render targets.

2023-03-16
