Math notation mapping in Python / OpenGL?

Question

How can I display math notations / expressions in Python with OpenGL?

I use pyglet , however it uses OpenGL.

Things like this :

I cannot store static images since I also generate expressions.

Answer 1

I would say by creating a suitable latex expression, turning it into an image, and then load the image as a texture.

Answer 2

You can use the GL_TEXTURE_RECTANGLE_ARB extension to quickly load a dynamically generated image of arbitrary size into an OpenGL texture. You can find examples of using python to use dynamic vector graphics with opengl at http://cairographics.org/OpenGL/ , although if you want to display complex formulas, you also need to look at a suitable system such as latex.

Answer 3

I don't know about OpenGL bits. But matplotlib has a matplotlib.mathtext module for rendering a subset of TeX math expressions.
