Class StencilParameters

constructor

• new StencilParameters(options?): StencilParameters

• Create a new StencilParameters instance.

  Parameters

  • Optional options: object = {}

    Options object to configure the stencil parameters.

  Returns StencilParameters

Static Readonly DEFAULT

fail

• get fail(): number

• Returns number

• set fail(value): void

• Operation to perform if stencil test is failed. Can be:

  • STENCILOP_KEEP: don't change the stencil buffer value
  • STENCILOP_ZERO: set value to zero
  • STENCILOP_REPLACE: replace value with the reference value.
  • STENCILOP_INCREMENT: increment the value
  • STENCILOP_INCREMENTWRAP: increment the value, but wrap it to zero when it's larger than a maximum representable value
  • STENCILOP_DECREMENT: decrement the value
  • STENCILOP_DECREMENTWRAP: decrement the value, but wrap it to a maximum representable value, if the current value is 0
  • STENCILOP_INVERT: invert the value bitwise

  Parameters

  • value: number

  Returns void

func

• get func(): number

• Returns number

• set func(value): void

• A comparison function that decides if the pixel should be written, based on the current stencil buffer value, reference value, and mask value. Can be:

  • FUNC_NEVER: never pass
  • FUNC_LESS: pass if (ref & mask) < (stencil & mask)
  • FUNC_EQUAL: pass if (ref & mask) == (stencil & mask)
  • FUNC_LESSEQUAL: pass if (ref & mask) <= (stencil & mask)
  • FUNC_GREATER: pass if (ref & mask) > (stencil & mask)
  • FUNC_NOTEQUAL: pass if (ref & mask) != (stencil & mask)
  • FUNC_GREATEREQUAL: pass if (ref & mask) >= (stencil & mask)
  • FUNC_ALWAYS: always pass

  Parameters

  • value: number

  Returns void

key

• get key(): number

• Returns number

readMask

• get readMask(): number

• Returns number

• set readMask(value): void

• Mask applied to stencil buffer value and reference value before comparison.

  Parameters

  • value: number

  Returns void

ref

• get ref(): number

• Returns number

• set ref(value): void

• Sets stencil test reference value used in comparisons.

  Parameters

  • value: number

  Returns void

writeMask

• get writeMask(): number

• Returns number

• set writeMask(value): void

• A bit mask applied to the stencil value, when written.

  Parameters

  • value: number

  Returns void

zfail

• get zfail(): number

• Returns number

• set zfail(value): void

• Operation to perform if depth test is failed. Accepts the same values as fail.

  Parameters

  • value: number

  Returns void

zpass

• get zpass(): number

• Returns number

• set zpass(value): void

• Operation to perform if both stencil and depth test are passed. Accepts the same values as fail.

  Parameters

  • value: number

  Returns void

clone

• clone(): StencilParameters

• Clone the stencil parameters.

  Returns StencilParameters

  A cloned StencilParameters object.

copy

• copy(rhs): StencilParameters

• Copies the contents of a source stencil parameters to this stencil parameters.

  Parameters

  • rhs: StencilParameters

    A stencil parameters to copy from.

  Returns StencilParameters

  Self for chaining.
