karimnaaji / Live Glsl

live-glsl

A dynamic and lightweight shader coding tool. It dynamically reloads your shader, does on-screen error reporting and allows for GUI elements to be added from a shader syntax; allowing for uniform value tweaks.

build and run

> cmake . -Bbuild
> cmake --build build

> ./live-glsl.out fragment_shader_to_watch

example

To run the example, simply run ./build/live-glsl.out examples/atmosphere.frag from the main directory after building from sources.

builtin uniforms

• time : float
• resolution : vec2

GUI elements

GUI elements allows to control shader uniform inputs. They use a specific syntax and should be placed right before the uniform statement they are associated with.

The following GUI elements are supported:

• slider1
• slider2
• slider3
• slider4
• drag1
• drag2
• drag3
• drag4
• color3
• color4

GUI elements should be preceded by an @ and immediately followed by their parameters in parenthesis.

Drag types follow the syntax drag(speed, min_value, max_value). For example:

@drag2(0.1, 0.0, 1.0)
uniform vec2 uniform_name;

Slider types follow the syntax slider(min_value, max_value). For example:

@slider1(-1.0, 1.0)
uniform float uniform_name;

Color types do not need any parameter.
