Detailed Description

Manages a cubemap depth texture for rendering shadows from point lights.

This class encapsulates the creation and management of a framebuffer object (FBO) and a cubemap depth texture used for shadow mapping with point lights. It provides methods to bind and unbind the FBO, bind the cubemap depth texture for use in shaders, and retrieve the texture ID and resolution.

Note

The default resolution is set to 1024x1024 pixels per face.

Constructor & Destructor Documentation

CubemapShadowMap()

lmgl::renderer::CubemapShadowMap::CubemapShadowMap

(

unsigned int

resolution = 1024

)

Constructs a CubemapShadowMap with the specified resolution.

Creates a framebuffer object and a cubemap depth texture for shadow mapping.

Parameters

resolution

The resolution of each face of the cubemap shadow map. Default is 1024.

Member Function Documentation

bind()

void lmgl::renderer::CubemapShadowMap::bind

(

unsigned int

face

)

Binds the framebuffer object for rendering to a specific face of the cubemap shadow map.

This method binds the FBO so that subsequent rendering commands will write depth information to the specified face of the cubemap shadow map texture.

Parameters

face	The index of the cubemap face to bind (0-5).

Note

Make sure to unbind the FBO after rendering using the unbind method.

bind_texture()

void lmgl::renderer::CubemapShadowMap::bind_texture

(

unsigned int

slot = 0

)

const

Binds the cubemap depth texture to the specified texture slot for use in shaders.

This method binds the cubemap depth texture so that it can be sampled in shaders for shadow calculations.

Parameters

slot	The texture slot to bind the cubemap depth texture to. Default is 0.

get_resolution()

unsigned int lmgl::renderer::CubemapShadowMap::get_resolution ( ) const

inline

Returns the resolution of each face of the cubemap shadow map.

Returns

The resolution of each face in pixels.

get_texture_id()

unsigned int lmgl::renderer::CubemapShadowMap::get_texture_id ( ) const

inline

Returns the OpenGL texture ID of the cubemap depth texture.

Returns

The texture ID of the cubemap depth texture.

unbind()

void lmgl::renderer::CubemapShadowMap::unbind

(

)

Unbinds the framebuffer object, returning to the default framebuffer.

This method should be called after rendering to the cubemap shadow map is complete. It restores rendering to the default framebuffer.
