Function Documentation

create_box()

Builder eu::core::geom::create_box	(	float	x,
		float	y,
		float	z,
		NormalsFacing	normals_facing,
		const Rgb &	color = colors::white
	)

#include <libs/core/src/eu/core/geom.builder.h>

Creates a box/cube mesh.

Parameters

x	The width of the box (size along the x-axis).
y	The height of the box (size along the y-axis).
z	The depth of the box (size along the z-axis).
normals_facing	Specifies the direction the box's normals are facing.
color	The color of the box.

Returns

A Builder representing the generated mesh.

create_uv_sphere()

Builder eu::core::geom::create_uv_sphere	(	float	diameter,
		int	longitude_count,
		int	latitude_count,
		NormalsFacing	normals_facing,
		const Rgb &	color = colors::white
	)

#include <libs/core/src/eu/core/geom.builder.h>

Creates a UV sphere mesh.

Parameters

diameter	The diameter of the sphere.
longitude_count	The number of lines to go vertical, from pole to pole, aka meridians. Must be at least 3.
latitude_count	The number of lines that go horizontal, parallels to the equator, which is one of those lines.
normals_facing	The direction that the normals should face.
color	The color to apply to the sphere.

Returns

A Builder object representing the generated mesh.
