#include <Magnum/Shaders/Phong.h>
PhongLightUniform Light parameters for Phong shaders.
Describes light properties for each light used by the shader, either all PhongGL::
Constructors, destructors, conversion operators
- PhongLightUniform(DefaultInitT = DefaultInit) explicit constexpr noexcept
- Construct with default parameters.
- PhongLightUniform(NoInitT) explicit noexcept
- Construct without initializing the contents.
Public variables
Convenience setters
Provided to allow the use of method chaining for populating a structure in a single expression, otherwise equivalent to accessing the fields directly. Also guaranteed to provide backwards compatibility when packing of the actual fields changes.
- auto setPosition(const Vector4& position) -> PhongLightUniform&
- Set the position field.
- auto setColor(const Color3& color) -> PhongLightUniform&
- Set the color field.
- auto setSpecularColor(const Color3& specularColor) -> PhongLightUniform&
- Set the specularColor field.
- auto setRange(Float range) -> PhongLightUniform&
- Set the range field.

Variable documentation
Vector4 Magnum:: Shaders:: PhongLightUniform:: position
Position.
Depending on the fourth component, the value is treated as either a camera-relative position of a point light, if the fourth component is 1.0f
; or a direction to a directional light, if the fourth component is 0.0f
. Default value is {0.0f, 0.0f, 1.0f, 0.0f}
— a directional "fill" light coming from the camera.
Color3 Magnum:: Shaders:: PhongLightUniform:: specularColor
Specular color.
Usually you'd set this value to the same as color, but it allows for greater flexibility such as disabling specular highlights on certain lights. Default value is 0xffffff_rgbf
.
Float Magnum:: Shaders:: PhongLightUniform:: range
Attenuation range.
Default value is Constants::
