gptex

Makes a ptexture image file from a geometry file.

On this page

gptex reads a geometry file and generates a ptexture file containing an image for each face in the geometry.

Usage

You can specify image files for each face on the command line, or use the -f option to specify a text file containing an image file name on each line.

  1. gptex geofile ptexfile [imagefile ...]

  2. gptex -f map_list_file geofile ptexfile

Notes

  • The geometry file must contain four sided polygons.

  • The image files must be power of 2 in their resolution.

  • All image files must have the same number of color channels and storage type (for example, if one image is 8 bit RGB, all images must be 8 bit RGB).

Options

-v

(Verbose) Print information about progress.

-f map_list_file

Read individual face textures from the a text file.

== Examples ===

Generate a ptexture file for a cube with the 6 image files specified:

gptex box.geo box.ptx face0.pic face1.exr face2.tif face3.pic face4.png face5.pic

Generate a ptexture file for a more complicated model, using the file maplist.txt to specify the filenames for each face texture, printing progress information to stdout:

gptex -v -f maplist.txt model.bgeo model.ptx
