Detailed Description

Renders shadows for directional and point lights using shadow maps.

This class provides methods to render shadows for both directional lights and point lights using the respective shadow maps. It utilizes depth shaders to render the scene from the light's perspective and generate the shadow maps.

Constructor & Destructor Documentation

ShadowRenderer()

lmgl::renderer::ShadowRenderer::ShadowRenderer

(

)

Constructs a ShadowRenderer and initializes depth shaders.

Initializes the depth shaders used for rendering shadows. The default constructor sets up the necessary shaders for both directional and point light shadow mapping.

Member Function Documentation

get_light_space_matrix()

glm::mat4 lmgl::renderer::ShadowRenderer::get_light_space_matrix	(	std::shared_ptr< scene::Light >	light,
		const glm::vec3 &	scene_center,
		float	scene_radius )

Computes the light space matrix for a directional light.

This method calculates the light space transformation matrix used for shadow mapping based on the light's direction and the scene's bounding sphere.

Parameters

light	The directional light.
scene_center	The center of the scene's bounding sphere.
scene_radius	The radius of the scene's bounding sphere.

Returns

The computed light space matrix.

render_directional_shadow()

void lmgl::renderer::ShadowRenderer::render_directional_shadow	(	std::shared_ptr< scene::Scene >	scene,
		std::shared_ptr< scene::Light >	light,
		std::shared_ptr< ShadowMap >	shadow_map )

Renders the shadow map for a directional light.

This method renders the scene from the perspective of the directional light and populates the provided shadow map with depth information.

Parameters

scene	The scene to render.
light	The directional light casting shadows.
shadow_map	The shadow map to populate with depth information.

render_point_shadow()

void lmgl::renderer::ShadowRenderer::render_point_shadow	(	std::shared_ptr< scene::Scene >	scene,
		std::shared_ptr< scene::Light >	light,
		std::shared_ptr< CubemapShadowMap >	shadow_map )

Renders the shadow map for a point light.

This method renders the scene from the perspective of the point light and populates the provided cubemap shadow map with depth information.

Parameters

scene	The scene to render.
light	The point light casting shadows.
shadow_map	The cubemap shadow map to populate with depth information.
