PyGLM 0.4.4b1

OpenGL Mathematics library for Python

GLSL + Optional features + Python = PyGLM

A mathematics library for graphics programming written in C.

Work in progress.

PyGLM is based on GLM by G-Truc offering a lot of the original features.

PyGLM is missing some features, either because they couldn't be implemented properly

or were deemed to be of too low priority (like glm::detail::tvec1).

If you encounter any issues or want to request a feature, please create an issue on the issue tracker.

Why PyGLM?

Besides the obvious - being compatible with GLM - PyGLM offers a variety of features for vector and matrix manipulation.

It has a lot of possible use cases, including 3D-Graphics (OpenGL, DirectX, ...), Physics and more.

At the same time, it has great performance, being between 2x and 10x as fast as numpy!

(depending on the individual function)

Installation

PyGLM supports Windows, Linux, MacOS and other operating systems with either x86 (32-bit) or x64 (64-bit) architecture,

running Python 2 or 3

It can be installed from the PyPI using pip:

pip install pyglm

And finally imported and used:

import glm

Using PyGLM

PyGLM's syntax is very similar to the original GLM's syntax.

There is no need to import anything but glm, as it already contains the entire package.

Instead of using double colons (::) for namespaces, periods (.) are used, so

glm::detail::tvec2

becomes

glm.detail.tvec2

You can also use the base namespace glm.

glm.tvec2

There is no way to set preprocessor definitions (macros).

If - for example - you need to use the left handed coordinate system, you have to use *LH, so

glm.perspective

becomes

glm.perspectiveLH

There is currently no documentation for PyGLM.

Please refer to the source (in Python: *.__doc__) and GLM manuals, references and tutorials.

Example

>>> import glm
>>> v = glm.vec3()
>>> v.x = 7
>>> print(v.xxx)
tvec3(            7,            7,            7 )

>>> m = glm.mat4()
>>> print(m)
[            0 |            0 |            0 |            0 ]
[            0 |            0 |            0 |            0 ]
[            0 |            0 |            0 |            0 ]
[            0 |            0 |            0 |            0 ]

>>> v = glm.vec4(1, 2, 3, 4)
>>> print(v + (8, 7, 6, 5))
tvec4(            9,            9,            9,            9 )
