Polygon Model eXtended example library

libpmx

Polygon Model eXtended library.

Implemented based on PMX 2.1 description.

Basic usage

#include <pmx.h>
#include <stdio.h>

FILE * const pmx_file = fopen( "example_model.pmx", "rb" ); // Open example model in binary read mode

if ( pmx_file ) {
	char header[PMX_HEAD_LEN];
	float version;

	fread( header, PMX_HEAD_LEN, 1, pmx_file ); // Read the header

	version = pmx_header_version( header, PMX_HEAD_LEN ); // Get the pmx version
	// An invalid header will report version 0.0f

	if ( version ) {
		pmx_struct pmx = pmx_create_read_struct( version, NULL, NULL, NULL );

		if ( pmx ) {
			pmx_info info = pmx_create_info_struct( pmx );

			if ( info ) {
				pmx_init_io( pmx, pmx_file ); // Set file handle
				pmx_set_head_bytes( pmx, PMX_HEAD_LEN ); // We already read the header

				pmx_read_info( pmx, info ); // Read everything up to model data

				pmx_destroy_info_struct( pmx, info ); // Dealloc info
			}
			pmx_destroy_read_struct( pmx ); // Dealloc reader
		}
	}

	fclose( pmx_file ); // Close file
}
