Fujiyama Renderer0.2.9、MagicaVoxelからobjをexport。blenderに読み込みply出力。s,tをuv1,uv2に書き換え、textureをjpgにして読み込みました。直接jpgやplyを読み込んでます。objの表示に影が出るのでplyを使います。

Magicavoxelのtextureは拡大。Magicavoxelからobj出力時のテクスチャは1 x 256pixels、変換できないので、100 x 256にしたらできました。ありがとうございます。

# 1 teapot with 32 point lights

# This script is the python version of teapot.scn with minor changes.

# It also demonstrates how to load *.ply and *.hdr files

# directly without pre-conversion.
