Constructs a new point light

This contructs a new point light with default settings. By default the light is set to be an infinitely small point light source. You can change this with RPPointLight::set_inner_radius.

Definition at line 37 of file rpPointLight.cxx.

References RPLight::RPLight().

## Member Function Documentation

## ◆ init_shadow_sources()

void RPPointLight::init_shadow_sources | ( |  | ) |
| virtual

Inits the shadow sources of the light.

This inits all required shadow sources for the point light.

See also
  RPLight::init_shadow_sources

Implements RPLight.

Definition at line 60 of file rpPointLight.cxx.

## ◆ update_shadow_sources()

void RPPointLight::update_shadow_sources | ( |  | ) |
| virtual

Updates the shadow sources.

This updates all shadow sources of the light.

See also
  RPLight::update_shadow_sources

Implements RPLight.

Definition at line 73 of file rpPointLight.cxx.

References RPLight::get_shadow_map_resolution.

## ◆ write_to_command()

void RPPointLight::write_to_command | ( | GPUCommand & | cmd | ) |
| virtual

Writes the light to a GPUCommand.

This writes the point light data to a GPUCommand.

See also
  RPLight::write_to_command

Parameters

  cmd | The target GPUCommand

Reimplemented from RPLight.

Definition at line 49 of file rpPointLight.cxx.

References GPUCommand::push_float(), and RPLight::write_to_command().

## Member Data Documentation

## ◆ get_inner_radius

float RPPointLight::get_inner_radius
| inline

Returns the inner radius of the light.

This returns the inner radius of the light, previously set with RPPointLight::get_inner_radius.

Returns
  [description]

Definition at line 49 of file rpPointLight.h.

## ◆ get_radius

float RPPointLight::get_radius
| inline

Returns the lights radius.

This returns the lights radius previously set with RPPointLight::set_radius

Returns
  Light radius in world space

Definition at line 45 of file rpPointLight.h.

## ◆ set_inner_radius

void RPPointLight::set_inner_radius
| inline

Sets the inner radius of the light.

This sets the inner radius of the light. Anything greater than zero causes the light to get an area light. This has influence on the specular highlights of the light aswell as the shadows.

The inner radius controls the size of the lights sphere size in world space units. A radius of 0 means the light has no inner radius, and the light will be have like an infinite small point light source. A radius greater than zero will cause the light to behave like it would be an emissive sphere with the given inner radius emitting light. This is more physically correct.

Parameters

  inner_radius | Inner-radius in world space

Definition at line 49 of file rpPointLight.h.

## ◆ set_radius

void RPPointLight::set_radius
| inline

Sets the radius of the light

This sets the radius of the light. It controls the lights influence. After a distance greater than this radius, the light influence is zero.

Parameters

  radius | Light radius in world space
