Detailed Description

Write an ITKMesh to an OBJ file.

Author

Seth Parker

Date

6/24/15

Writes both textured and untextured meshes in ASCII OBJ format. Texture information is automatically written if a UV map is set and is not empty.

Definition at line 29 of file OBJWriter.hpp.

Member Function Documentation

setPath()

void volcart::io::OBJWriter::setPath

(

const filesystem::path &

path

)

Set the output path.

write() and validate() will fail if path does not have an expected file extension (.obj/.OBJ).

setTextureFormat()

void volcart::io::OBJWriter::setTextureFormat

(

std::string

fmt

)

Set the texture image format.

Passed value will be used as the file extension when writing the texture image. Example values: tif, jpg, png.

write()

void volcart::io::OBJWriter::write

(

)

Write the OBJ to disk.

If UV Map is not empty, automatically writes MTL and texture image.

Exceptions

volcart::IOException

write_faces_()

void volcart::io::OBJWriter::write_faces_ ( )

private

Write the OBJ faces

write_header_()

void volcart::io::OBJWriter::write_header_ ( )

private

Write the OBJ header

write_mtl_()

void volcart::io::OBJWriter::write_mtl_ ( )

private

Write the MTL file

write_obj_()

void volcart::io::OBJWriter::write_obj_ ( )

private

Write the OBJ file

write_texture_()

void volcart::io::OBJWriter::write_texture_ ( )

private

Write the texture file

write_texture_coordinates_()

void volcart::io::OBJWriter::write_texture_coordinates_ ( )

private

Write the OBJ texture coordinates

write_vertices_()

void volcart::io::OBJWriter::write_vertices_ ( )

private

Write the OBJ vertices
