OGRECave/ogre

The High-Performance Rendering Backend

OGRE (Object-Oriented Graphics Rendering Engine) is a proven, modular C++ renderer for custom engine development. It empowers engine programmers and industrial simulation developers to build high-performance 3D applications in C++ and Python efficiently.

Start with a battle-tested, flexible rendering backend that scales from embedded robotics to high-end visualization tools. OGRE abstracts Vulkan, Direct3D, and OpenGL so you can focus on your engine's logic.

Instant Prototyping with Python

Experience rapid prototyping with our high-level Python bindings (HighPy). Get a PBR scene running in seconds:

# pip install ogre-python
import Ogre.HighPy as ohi

# Create a window
ohi.window_create("Ogre", window_size=(1280, 720))

# Load a mesh (glTF 2.0, OBJ, or Ogre Mesh)
ohi.mesh_show("Ogre", "DamagedHelmet.glb", position=(0, 0, -3))
ohi.point_light("Ogre", position=(0, 10, 0))
# Main Loop
while ohi.window_draw("Ogre") != 27: # Press ESC to exit
    pass
