Type Alias VFXPostEffect

Type declaration

• shader: ShaderPreset | string

  Fragment shader code or preset name to be applied as a post effect.
  You can pass a preset name from ShaderPreset (e.g., "invert", "grayscale", "sepia")
  or provide custom shader code.

  The shader will receive the rendered canvas as a sampler2D src uniform.

  Standard uniforms available:

  • sampler2D src: The input texture (rendered canvas)
  • vec2 resolution: Canvas resolution in pixels
  • vec2 offset: Offset values
  • vec4 viewport: Viewport information
  • float time: Time in seconds since VFX started
  • vec2 mouse: Mouse position in pixels
  • sampler2D backbuffer: Previous frame texture (if backbuffer is enabled)

• Optionaluniforms?: VFXUniforms

  Custom uniform values to be passed to the post effect shader.
  Works the same way as element uniforms.

• Optionalbackbuffer?: boolean

  Whether the post effect should use a backbuffer for feedback effects.
  When enabled, the previous frame's output is available as sampler2D backbuffer.
