IndexType

typedef std::array<size_t, 3> OBJFile::IndexType

Index triple forming one triangle (zero-based vertex indices).

Note

Indices reference entries in vertices.

Constructor & Destructor Documentation

OBJFile()

OBJFile::OBJFile	(	const std::string &	filename,
		bool	normalize = false )

Load an OBJ file.

Parameters

filename	Path to the .obj file.
normalize	If true, recenter to AABB center and scale uniformly by the longest extent so the model fits into a unit cube.

Exceptions

std::runtime_error

On I/O failures or malformed input (thrown from stream operations or conversions).

Here is the call graph for this function:

Member Data Documentation

indices

std::vector<IndexType> OBJFile::indices

Triangle index buffer (each element is one face as three indices).

normals

std::vector<Vec3> OBJFile::normals

Per-vertex normals.

If the file lacks "vn" records, these are computed by summing face normals around each vertex and normalizing.

vertices

std::vector<Vec3> OBJFile::vertices

Vertex positions parsed from "v" records (x,y,z).
