Adds a directional light.
Adds a directional light. Directional light comes from one direction: it is stronger when hitting a surface squarely, and weaker if it hits at a gentle angle. After hitting a surface, directional light scatters in all directions. Lights need to be included in the
draw() to remain persistent in a looping program. Placing them in the
setup() of a looping program will cause them to only have an effect the first time through the loop. The
v3 parameters are interpreted as either
HSB values, depending on the current color mode. The
nz parameters specify the direction the light is facing. For example, setting
ny to -1 will cause the geometry to be lit from below (since the light would be facing directly upward).
This method is the same as directional_light() but linked to a
Py5Graphics object. To see example code for how it can be used, see directional_light().
Underlying Processing method: PGraphics.directionalLight
directional_light( 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) nx: float, # direction along the x-axis ny: float, # direction along the y-axis nz: float, # direction along the z-axis /, ) -> None
