一种将 3d 模型的多个纹理组合成一个的工具? [英] A tool to combine multiple textures of a 3d model into one?
问题描述
我有一些 OBJ 格式的 3D 模型，带有 MTL 材料和 JPG/PNG 纹理.基本上它们看起来像这样:
I have some 3D models in OBJ format with MTL material and JPG/PNG textures. Basically they look like this:
- 在 OBJ 中:
mtllib material_file.mtl
... # some vertices and texture vertices
usemtl material_0
... # some faces
usemtl material_1
... # some faces
... # more
- 在 MTL 中:
newmtl material_0
... #Ka, Kd, Ks, etc.
map_Kd texture_1.png
newmtl material_0
... #Ka, Kd, Ks, etc.
map_Kd texture_2.png
... # more
但是，现在我需要渲染和体素化这些模型以提供给神经网络，其预处理工具仅支持带有单个 PNG/JPG 纹理文件的 OBJ.所以我需要将这些纹理合并到一个文件中.
However, now I need to render and voxelize these model to feed to a neural network, whose preprocessing tool only supports OBJ with a single PNG/JPG texture file. So I need to combine these textures into a single file.
有什么工具可以做到这一点吗?如果我可以在脚本中使用它会更好.
Is there any tool for that? It would be preferable if I can use it in a script.
推荐答案
Atlas_texture_packer 似乎是将多个纹理合二为一的有效工具:https://github.com/lucars83/Atlas_Texture_Packer
The Atlas_texture_packer seem to be efficient tool to combine multiple textures into one: https://github.com/lucars83/Atlas_Texture_Packer
另一个是https://murlengine.com/usersguide/en/atlas_generator.php 需要XML文件形式的纹理文件信息.
Another is https://murlengine.com/usersguide/en/atlas_generator.php which needs the information about texture files in the form of XML file.
