        "description": "![Build Status](https://github.com/Moguri/panda3d-simplepbr/workflows/Pipeline/badge.svg)\n[![](https://img.shields.io/pypi/pyversions/panda3d_simplepbr.svg)](https://pypi.org/project/panda3d_simplepbr/)\n[![Panda3D Versions](https://img.shields.io/badge/panda3d-1.10%20%7C%201.11-blue.svg)](https://www.panda3d.org/)\n[![](https://img.shields.io/github/license/Moguri/panda3d-simplepbr.svg)](https://choosealicense.com/licenses/bsd-3-clause/)\n\n# panda3d-simplepbr\n\nThis is a simple, basic, lightweight, no-frills PBR render pipeline for [Panda3D](https://www.panda3d.org/).\nIt is currently intended to be used with [panda3d-gltf](https://github.com/Moguri/panda3d-gltf), which will output textures in the right order.\nThe PBR shader is heavily inspired by the [Khronos glTF Sample Viewer](https://github.com/KhronosGroup/glTF-Sample-Viewer).\n*Note:* this project does not make an attempt to match a reference renderer.\n\n## Features\n* Supports running on potatoes with an easy OpenGL 2.1+ requirement\n* Forward rendered metal-rough PBR\n* All Panda3D light types except ambient (point, directional, and spot)\n* Filmic tonemapping \n\n## Notable Todos\nThere are a few big things still missing and are planned to be implemented:\n\n* Normals\n* Shadow mapping\n* Environment maps\n\n## Other missing features\nThe goal is to keep this simple and lightweight.\nAs such, the following missing features are *not* currently on the roadmap:\n\n* Something to deal with many lights (e.g., deferred, forward+, tiling, clustering, etc.)\n* Fancy post-process effects (temporal anti-aliasing, ambient occlusion, screen-space reflections)\n* Environment probes\n\n## Installation\n\nUse pip to install the `panda3d-simplepbr` package:\n\n```bash\npip install panda3d-simplepbr\n```\n\nTo grab the latest development build, use:\n\n```bash\npip install git+https://github.com/Moguri/panda3d-simplepbr.git\n\n```\n\n## Usage\n\nJust add `simplepbr.init()` to your `ShowBase` instance:\n\n```python\nfrom direct.showbase.ShowBase import ShowBase\n\nimport simplepbr\n\nclass App(ShowBase):\n    def __init__(self):\n        super().__init__()\n\n        simplepbr.init()\n```\n\nThe `init()` function will choose typical defaults, but the following can be modified via keyword arguments:\n\n`render_node`\n: The node to attach the shader too, defaults to `base.render` if `None`\n`window`\n: The window to attach the framebuffer too, defaults to `base.win` if `None`\n`camera_node`\n: The NodePath of the camera to use when rendering the scene, defaults to `base.cam` if `None`\n\n### Textures\n\nThe shader currently assumes that the following textures are in these slots:\n\n0. BaseColor\n1. MetalRoughness\n2. Normals (not currently supported)\n\n## Example\n\nFor an example application using `panda3d-simplepbr` check out the [viewer](https://github.com/Moguri/panda3d-gltf/blob/master/gltf/viewer.py) in the [panda3d-gltf repo](https://github.com/Moguri/panda3d-gltf).\n\n## Running tests\n```bash\npython setup.py test\n```\n\n## License\n[B3D 3-Clause](https://choosealicense.com/licenses/bsd-3-clause/)\n\n\n",
