No PyOpenGL version which compatible with manimgl 1.6.1 #2073

ludalevy commented 11 months ago

The following script has been run after installing manimgl 1.6.1: manimgl example_scenes.py OpeningManimExample

The running error is: OpenGL/error.py", line 230, in glCheckError raise self._errorClass( OpenGL.error.GLError: GLError( err = 1280, description = b'invalid enumerant', baseOperation = glBlendFuncSeparate, cArguments = ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA, GL_ONE, ) )

File shader_wrapper.py contains code gl.glBlendFuncSeparate(

Ordinary blending for colors

        gl.GL_SRC_ALPHA, gl.GL_ONE_MINUS_SRC_ALPHA,
        # The effect of blending with -a / (1 - a)
        # should be to cancel out
        gl.GL_ONE_MINUS_DST_ALPHA, gl.GL_ONE,
    )

I cloned the code from this repository on GitHub and tried to install it using 'pip install -e .', but I encountered the same problem. However, after attempting to uninstall it and then directly installing with 'pip install minimgl', the issue was resolved.

got the same problem:

File ".../lib/python3.11/site-packages/OpenGL/error.py", line 230, in glCheckError raise self._errorClass( OpenGL.error.GLError: GLError( err = 1280, description = b'invalid enumerant', baseOperation = glBlendFuncSeparate, cArguments = ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA, GL_ONE, ) )

Refer to #2078, I've test it on my macos sonoma 14.1.2, and the result is that: This problem can be resolve when using "pip install manimgl", but can not run on "pip install -e ."

geoochi commented 11 months ago

Interestingly, I successfully tested "pip install -e ." last week with Sonoma 14.1.1 But this week, it seems to be failing with 14.1.2. Is this really related to the macOS version?
