Member Function Documentation

◆ generate()

entity::id terrain_system::generate	(	std::shared_ptr< gl::image_2d >	heightmap,
		const math::uvec2 &	subdivisions,
		const math::transform< float > &	transform,
		std::shared_ptr< render::material >	material
	)

Generates terrain entities from a heightmap.

Parameters

heightmap	Heightmap from which the terrain should be generated.
subdivisions	Number of heightmap subdivisions on the x- and z-axes. Determines the number of terrain entities generated.
transform	Translation, rotation, and scale of the terrain.
material	Terrain material.

Returns: Entity ID of the generated terrain grid.

@except std::invalid_argument Failed to generate terrain from null heightmap. @except std::runtime_error Heightmap size less than 2x2. @except std::runtime_error Heightmap subdivision failed.

◆ update()

void terrain_system::update	(	float	t,
		float	dt
	)

virtual

Perform's a system's update() function.

Parameters

t	Total elapsed time, in seconds.
dt	Delta time, in seconds.

Implements updatable_system.
