contextChange

• contextChange(gl: IRenderingContext): void

• Parameters

  • gl: IRenderingContext

  Returns void

forceState

• forceState(state: State): void

• Sets the state, when previous state is unknown.

  Parameters

  • state: State

    The state to set

  Returns void

reset

• reset(): void

• Resets all the logic and disables the VAOs.

  Returns void

set

• set(state: State): void

• Sets the current state

  Parameters

  • state: State

    The state to set.

  Returns void

setBlend

• setBlend(value: boolean): void

• Sets whether to enable or disable blending.

  Parameters

  • value: boolean

    Turn on or off WebGl blending.

  Returns void

setBlendMode

• setBlendMode(value: number): void

• Sets the blend mode.

  Parameters

  • value: number

    The blend mode to set to.

  Returns void

setCullFace

• setCullFace(value: boolean): void

• Sets whether to enable or disable cull face.

  Parameters

  • value: boolean

    Turn on or off webgl cull face.

  Returns void

setDepthMask

• setDepthMask(value: boolean): void

• Sets whether to enable or disable depth mask.

  Parameters

  • value: boolean

    Turn on or off webgl depth mask.

  Returns void

setDepthTest

• setDepthTest(value: boolean): void

• Sets whether to enable or disable depth test.

  Parameters

  • value: boolean

    Turn on or off webgl depth testing.

  Returns void

setFrontFace

• setFrontFace(value: boolean): void

• Sets the gl front face.

  Parameters

  • value: boolean

    true is clockwise and false is counter-clockwise

  Returns void

setOffset

• setOffset(value: boolean): void

• Sets whether to enable or disable polygon offset fill.

  Parameters

  • value: boolean

    Turn on or off webgl polygon offset testing.

  Returns void

setPolygonOffset

• setPolygonOffset(value: number, scale: number): void

• Sets the polygon offset.

  Parameters

  • value: number

    the polygon offset
  • scale: number

    the polygon offset scale

  Returns void

updateCheck

• updateCheck(func: (system: this, state: State) => void, value: boolean): void

• Checks to see which updates should be checked based on which settings have been activated.

  For example, if blend is enabled then we should check the blend modes each time the state is changed or if polygon fill is activated then we need to check if the polygon offset changes. The idea is that we only check what we have too.

  Parameters

  • func: (system: this, state: State) => void

    the checking function to add or remove
  • value: boolean

    should the check function be added or removed.

  Returns void
