Functions
LG_Mesh *	lg_fbx2vbo (const char *path, zboolean invert_z, zboolean normalize_xyz, zboolean horiz_center, zboolean vert_center, zboolean vert_bottom)
void	lg_vb_uvn_iw_info (Vertex_uvn_iw *vb_data, uint32_t vb_size, int n_lines_max, const char *line_start, zboolean is_triangle_mesh)

Detailed Description

=== The FBX file parser ===

We use the excellent ufbx lib, by Samuli Raivio.

At the moment, the aim is to read skinned meshes, as OBJ files don't support them.

See: https://ufbx.github.io and https://github.com/ufbx/ufbx

Function Documentation

lg_fbx2vbo()

LG_Mesh* lg_fbx2vbo	(	const char *	path,
		zboolean	invert_z,
		zboolean	normalize_xyz,
		zboolean	horiz_center,
		zboolean	vert_center,
		zboolean	vert_bottom
	)

Parse a FBX file to build a skinned mesh

Will create a Vertex_uvn_iw VBO (see lg_vertex.h)

Parameters

path	FBX file path
invert_z	Invert z spatial coord (left_handed vs right_handed coords sys) - STILL EXPERIMENTAL
normalize_xyz	Normalize spatial coords
horiz_center	Center mesh horizontally
vert_center	Center mesh vertically, if vert_bottom is not set
vert_bottom	Set mesh origin vertically at bottom, override vert_center

Returns

The new mesh

lg_vb_uvn_iw_info()

void lg_vb_uvn_iw_info	(	Vertex_uvn_iw *	vb_data,
		uint32_t	vb_size,
		int	n_lines_max,
		const char *	line_start,
		zboolean	is_triangle_mesh
	)

Print out nicely a Vertex_uvn_iw buffer info spatial coords (only)

v[1/2/3] applies only for triangle meshes

Parameters

vb_data	Pointer to a Vertex_uvn_iw buffer
vb_size	Buffer size (uint32_t)
n_lines_max	Print out up to n_lines_max lines
line_start	String starting each line
is_triangle_mesh
