Class ShaderSystem

constructor

• new ShaderSystem(renderer: Renderer): ShaderSystem

• Parameters

  • renderer: Renderer

    The renderer this System works for.

  Returns ShaderSystem

destroyed

id

program

shader

bind

• bind(shader: Shader, dontSync?: boolean): GLProgram

• Changes the current shader to the one given in parameter.

  Parameters

  • shader: Shader

    the new shader
  • OptionaldontSync: boolean

    false if the shader should automatically sync its uniforms.

  Returns GLProgram

  the glProgram that belongs to the shader.

createSyncGroups

• createSyncGroups(group: UniformGroup<Dict<any>>): UniformsSyncCallback

• Parameters

  • group: UniformGroup<Dict<any>>

  Returns UniformsSyncCallback

destroy

• destroy(): void

• Destroys this System and removes all its textures.

  Returns void

disposeShader

• disposeShader(shader: Shader): void

• Disposes shader. If disposing one equals with current shader, set current as null.

  Parameters

  • shader: Shader

    Shader object

  Returns void

generateProgram

• generateProgram(shader: Shader): GLProgram

• Generates a glProgram version of the Shader provided.

  Parameters

  • shader: Shader

    The shader that the glProgram will be based on.

  Returns GLProgram

  A shiny new glProgram!

getGlProgram

• getGlProgram(): GLProgram

• Returns the underlying GLShade rof the currently bound shader.

  This can be handy for when you to have a little more control over the setting of your uniforms.

  Returns GLProgram

  The glProgram for the currently bound Shader for this context

reset

• reset(): void

• Resets ShaderSystem state, does not affect WebGL state.

  Returns void

setUniforms

• setUniforms(uniforms: Dict<any>): void

• Uploads the uniforms values to the currently bound shader.

  Parameters

  • uniforms: Dict<any>

    the uniforms values that be applied to the current shader

  Returns void

syncUniformBufferGroup

• syncUniformBufferGroup(group: UniformGroup<Dict<any>>, name?: string): void

• Syncs uniform buffers

  Parameters

  • group: UniformGroup<Dict<any>>

    the uniform buffer group to sync
  • Optionalname: string

    the name of the uniform buffer

  Returns void

syncUniformGroup

• syncUniformGroup(group: UniformGroup<Dict<any>>, syncData?: any): void

• Syncs uniforms on the group

  Parameters

  • group: UniformGroup<Dict<any>>

    the uniform group to sync
  • OptionalsyncData: any

    this is data that is passed to the sync function and any nested sync functions

  Returns void

syncUniforms

• syncUniforms(
      group: UniformGroup<Dict<any>>,
      glProgram: GLProgram,
      syncData: any,
  ): void

• Overrideable by the @pixi/unsafe-eval package to use static syncUniforms instead.

  Parameters

  • group: UniformGroup<Dict<any>>
  • glProgram: GLProgram
  • syncData: any

  Returns void
