library2.8.3pypypi✓ verified 87d ago

PyGLM is an OpenGL Mathematics library for Python, providing vector and matrix types, and mathematical functions for graphics programming. It is a Python extension written in C++ that wraps the popular GLM (OpenGL Mathematics) library. The current version is 2.8.3. It maintains an infrequent but active release cadence, focusing on stability and compatibility with its underlying C++ counterpart.

glm

✓ import glm

✗ from pyglm import glm (before v2.8), import pyglm

The module is imported as 'glm'. In PyGLM versions 2.7.3 and earlier, 'try: from pyglm import glm except ImportError: import glm' was suggested. Direct 'import glm' is currently the standard but will be deprecated in PyGLM 3.0 in favor of 'from pyglm import glm'.

This quickstart demonstrates basic vector and matrix initialization and operations using the `glm` module. It shows how to create vectors and matrices, access components, and perform arithmetic operations.

import glm # Vector operations v = glm.vec3() v.x = 7 print(f"v.xxy: {v.xxy}") # Matrix initialization m = glm.mat4() print(f"m:\n{m}") # Vector arithmetic with iterables v_sum = glm.vec4(1, 2, 3, 4) + (8, 7, 6, 5) print(f"v_sum: {v_sum}")

Debug

Known issues

breakingThe direct import `import glm` will be deprecated in PyGLM 3.0. Users should transition to `from pyglm import glm` for future compatibility.

fix

Update your import statement from `import glm` to `from pyglm import glm`.

affects: >=3.0 (future)

gotchaPyGLM's syntax differs from the original C++ GLM library in several ways, including using `.` instead of `::` for namespaces (e.g., `glm.vec2`), requiring `_LH` suffix for left-handed coordinate system functions (e.g., `glm.perspectiveLH`), and using default `packed_highp` precision.

fix

Refer to the PyGLM documentation or wiki for specific syntax differences when porting C++ GLM code.

affects: All versions

gotchaCertain functions, like `glm.frexp`, may issue a `UserWarning`. These can be silenced if desired.

fix

Use `glm.silence(ID)` to silence specific warnings, or `glm.silence(0)` to silence all warnings. Check the `glm` module's function reference for warning IDs.

affects: All versions

gotchaThe GLM C++ library, which PyGLM wraps, is licensed under the MIT License. Users are required to include the GLM license (`COPYING` or `GLM_LICENSE` file) in their projects, especially for binary distributions.

fix

Copy the `COPYING` or `GLM_LICENSE` file from the PyGLM source to your project directory.

affects: All versions

Errors

Common errors & fixes

AttributeError: module 'glm' has no attribute 'vec2'

This error typically occurs when the wrong `glm` package has been installed. There is another package named `glm` on PyPI which is a JSON parser, not the OpenGL Mathematics library.

fix

Ensure you installed `pyglm` and not `glm`. Uninstall `glm` (`pip uninstall glm`) and then install the correct package (`pip install pyglm`).

ERROR: Failed building wheel for pyglm

PyGLM is a C++ extension and requires C++ build tools to be present on your system if a pre-compiled wheel is not available for your specific Python version and operating system. On Windows, this often means Visual C++ Build Tools.

fix

On Windows, install the 'Desktop development with C++' workload from the Visual Studio Installer. On Linux, ensure `build-essential` (Debian/Ubuntu) or `Development Tools` (Fedora/RHEL) are installed.
