Member Function Documentation

init_light()

void Light::init_light ( )

inline

Initializes the light object.

This function sets up the initial state of the light object, configuring any necessary parameters and preparing it for use in the application.

is_gui_element()

void Light::is_gui_element ( bool *  result )

inline

Determines if the current object is a GUI element.

This function sets the value pointed to by the result parameter to indicate whether the current object is a graphical user interface (GUI) element.

Parameters

result

A pointer to a boolean variable where the result will be stored. The value will be set to true if the current object is a GUI element, and false otherwise.

render()

void Light::render ( mat4  modelMatrix, Shader  activeShader  )

inline

Renders the light using the provided model matrix and active shader.

This function takes a model matrix and an active shader as parameters and performs the rendering of the light. The model matrix is used to transform the light's position and orientation in the scene, while the active shader is used to apply the appropriate shading effects.

Parameters

modelMatrix	Model matrix used for transforming the light.
activeShader	The shader program currently active for rendering.

init_vao()

void Light::init_vao ( )

inline

Initializes the Vertex Array Object (VAO) for the light class.

This function sets up the VAO which is used to store the vertex attribute configuration for the light objects. It binds the necessary buffers and configures the vertex attributes.

configure_lighting()

void Light::configure_lighting ( WorldShaders *  shaders, mat4  lightView, mat4  lightProjection, int  storageBufferIndex, DepthMap *  depthMap  )

inline

Configures the lighting for the scene.

This function configures the lighting for the scene by setting the light properties in the shader.

Parameters

shaders	The shaders to be used for rendering.
lightView	The view matrix for the light.
lightProjection	The projection matrix for the light.
storageBufferIndex	The index of the storage buffer.

Member Data Documentation

vbo

Light::vbo = 0

static

Static variable representing the Vertex Buffer Object (VBO) for the light class.

The VBO is used to store vertex data for rendering the lights in the OpenGL context.

vao

Light::vao = 0

static

Static variable representing the Vertex Array Object (VAO) for the light class.

The VAO is used to store the vertex attribute configuration for rendering the lights in the OpenGL context.

billboardShader

Light::billboardShader = 0

static

Static variable representing the shader program used for rendering billboard lights.

The shader program is used to render lights as billboards, which are 2D textures that always face the camera.

lightPointTexture

Light::lightPointTexture = 0

static

Static variable representing the texture map for point lights.

The texture map is used to apply a texture to point lights, enhancing their visual appearance in the OpenGL context.

directionalLightTexture

Light::directionalLightTexture = 0

static

Static variable representing the texture map for directional lights.

The texture map is used to apply a texture to directional lights, enhancing their visual appearance in the OpenGL context.
