Py5Graphics.spot_light()#

Adds a spot light.

Description#

Adds a spot light. The v1, v2, and v3 parameters are interpreted as either RGB or HSB values, depending on the current color mode. The x, y, and z parameters specify the position of the light and nx, ny, nz specify the direction of light. The angle parameter affects angle of the spotlight cone, while concentration sets the bias of light focusing toward the center of that cone.

This method is the same as spot_light() but linked to a Py5Graphics object. To see example code for how it can be used, see spot_light().

Underlying Processing method: PGraphics.spotLight

Syntax#

spot_light(v1: float, v2: float, v3: float, x: float, y: float, z: float, nx: float, ny: float, nz: float, angle: float, concentration: float, /) -> None

Parameters#

  • angle: float - angle of the spotlight cone

  • concentration: float - exponent determining the center bias of the cone

  • nx: float - direction along the x axis

  • ny: float - direction along the y axis

  • nz: float - direction along the z axis

  • v1: float - red or hue value (depending on current color mode)

  • v2: float - green or saturation value (depending on current color mode)

  • v3: float - blue or brightness value (depending on current color mode)

  • x: float - x-coordinate of the light

  • y: float - y-coordinate of the light

  • z: float - z-coordinate of the light
