Hi,
I am using Pyglet 1.2.4 to render a texturized 3D Mesh composed of
triangles and stored as an OBJ file. The mesh is not small, but also not
extremely huge: It takes up about 52 MB on the harddisk and consists of
roughly 800'000 faces (~ 366'500 vertices). The texture is available as a
.jpeg, takes up about 6.5 MB on the harddisk and its resolution is
8192x8192.
In order to upload the texture to the GPU, I do the following:
self._image = pyglet.image.load(image_path)
...
self._texture = self._image.get_texture()
which *sometimes *throws the following error:
...
self._texture = self._image.get_texture()
File "D:\Python27\lib\site-packages\pyglet\image\__init__.py", line 818,
in get_texture
force_rectangle)
File "D:\Python27\lib\site-packages\pyglet\image\__init__.py", line 809,
in create_texture
self.anchor_x, self.anchor_y, 0, None)
File "D:\Python27\lib\site-packages\pyglet\image\__init__.py", line 953,
in blit_to_texture
data = self._convert(data_format, data_pitch)
File "D:\Python27\lib\site-packages\pyglet\image\__init__.py", line 1008,
in _convert
self._ensure_string_data()
File "D:\Python27\lib\site-packages\pyglet\image\__init__.py", line 1076,
in _ensure_string_data
self._current_data = buf.raw
MemoryError
I tried to find out why this happens, but to no avail. I know that the
computer I am using is powerful enough to handle mesh sizes like that, both
because the error only happens sometimes and because I can visualize it
without problems using programs like e.g. Meshlab. Any help/hints how I can
resolve or further debug this are greatly appreciated!
Thanks a lot and best regards
Manuel
