shader_animated_t

ui::shader_animated_t

A pixel shader that may update based on the current time.

Pixel shaders are run on a per-pixel basis and do not have access to previous data or other pixels.

Parameters

color	The color of the current pixel, before any shader is applied.
coords	The [x,y] coordinates of the pixel, relative to the renderable this shader is applied to.
size	The [width,height] size of the renderable.
time	The current time in milliseconds.

shader_oneframe_t

ui::shader_oneframe_t

A pixel shader that's independent of the current time.

Pixel shaders are run on a per-pixel basis and do not have access to previous data or other pixels.

Parameters

color	The color of the current pixel, before any shader is applied.
coords	The [x,y] coordinates of the pixel, relative to the renderable this shader is applied to.
size	The [width,height] size of the renderable.

shader_t

ui::shader_t

A pixel shader that may or may not update based on the current time.

Pixel shaders are run on a per-pixel basis and do not have access to previous data or other pixels.

Parameters

color	The color of the current pixel, before any shader is applied.
coords	The [x,y] coordinates of the pixel, relative to the renderable this shader is applied to.
size	The [width,height] size of the renderable.
time	The current time in milliseconds.
