Detailed Description

Manages the rendering of scenes.

This class is responsible for rendering 3D scenes using OpenGL. It handles the rendering pipeline, including setting up the camera, managing render modes, and optimizing draw calls.

Constructor & Destructor Documentation

Renderer()

lmgl::renderer::Renderer::Renderer

(

)

Constructor for the Renderer class.

Initializes the renderer with default settings.

~Renderer()

lmgl::renderer::Renderer::~Renderer ( )

default

Destructor for the Renderer class.

Cleans up any resources used by the renderer.

Member Function Documentation

enable_post_processing()

void lmgl::renderer::Renderer::enable_post_processing

(

bool

enabled

)

Enables post processing effects based on tone map mode and exposure/gamma.

Parameters

enabled

Whether the postprocessing effects are enabled.

get_draw_calls()

unsigned int lmgl::renderer::Renderer::get_draw_calls ( ) const

inline

Get the number of draw calls made in the last render.

This method returns the number of draw calls that were made during the last rendering operation.

Returns

Number of draw calls.

get_render_mode()

RenderMode lmgl::renderer::Renderer::get_render_mode ( ) const

inline

Get the current rendering mode.

This method returns the current rendering mode of the renderer.

Returns

The current RenderMode.

get_triangles_count()

unsigned int lmgl::renderer::Renderer::get_triangles_count ( ) const

inline

Get the number of triangles rendered in the last render.

This method returns the total number of triangles that were rendered during the last rendering operation.

Returns

Number of triangles rendered.

render()

void lmgl::renderer::Renderer::render	(	std::shared_ptr< scene::Scene >	scene,
		std::shared_ptr< scene::Camera >	camera )

Render a scene from the perspective of a camera.

This method takes a scene and a camera as input and renders the scene using the specified camera's view and projection matrices. It also applies the current render mode and handles depth testing and blending based on the renderer's settings.

Parameters

scene	Shared pointer to the scene to be rendered.
camera	Shared pointer to the camera used for rendering.

resize()

void lmgl::renderer::Renderer::resize	(	int	width,
		int	height )

Resizes the framebuffer to specific width and height.

Parameters

width	The width to resize to.
height	The height to resize to.

set_blending()

void lmgl::renderer::Renderer::set_blending

(

bool

enabled

)

Enable or disable blending.

This method allows toggling blending, which is used for rendering transparent objects.

Parameters

enabled

True to enable blending, false to disable.

set_bloom_enabled()

void lmgl::renderer::Renderer::set_bloom_enabled ( bool enabled )

inline

Enable or disable bloom effect.

Parameters

enabled

True to enable bloom, false otherwise.

set_bloom_intensity()

void lmgl::renderer::Renderer::set_bloom_intensity ( float intensity )

inline

Sets the bloom intensity/strength.

Parameters

intensity

Bloom intensity (default 0.5f).

set_bloom_threshold()

void lmgl::renderer::Renderer::set_bloom_threshold ( float threshold )

inline

Sets the bloom brightness threshold.

Only pixels brighter than this value will bloom.

Parameters

threshold

Brightness threshold (default 1.0f).

set_culling()

void lmgl::renderer::Renderer::set_culling

(

bool

enabled

)

Enable or disable face culling.

This method allows toggling face culling, which can improve performance by not rendering faces of geometry that are not visible to the camera.

Parameters

enabled

True to enable culling, false to disable.

set_depth_test()

void lmgl::renderer::Renderer::set_depth_test

(

bool

enabled

)

Enable or disable depth testing.

This method allows toggling depth testing, which ensures that closer objects are rendered in front of farther ones.

Parameters

enabled

True to enable depth testing, false to disable.

set_exposure()

void lmgl::renderer::Renderer::set_exposure ( float exposure )

inline

Sets the exposure of the tone map.

Parameters

exposure

The exposure float value.

set_gamma()

void lmgl::renderer::Renderer::set_gamma ( float gamma )

inline

Sets the gamma of the tone map.

Parameters

gamma

The gamma float value.

set_render_mode()

void lmgl::renderer::Renderer::set_render_mode

(

RenderMode

mode

)

Set the rendering mode.

This method allows changing the rendering mode of the renderer. The mode can be set to solid, wireframe, or points, affecting how the geometry is displayed.

Parameters

mode	The desired rendering mode.

set_tone_map_mode()

void lmgl::renderer::Renderer::set_tone_map_mode ( int mode )

inline

Sets the tone map mode.

The tone map modes are:

• 0 = none;
• 1 = reinhard;
• 2 = aces.

Parameters

mode	The tone map mode.
