[PyOpenGL-Users] High Order glMap2 Error

[Shuai J. (Marshall) <mar...@gm...>]

Hi all,

I have some high order Bezier patches generated by Python that I want to
use OpenGL to draw. Unfortunately, it seems that PyOpenGl seems to only
handle orders up to 7 but I can plot Bezier patches in C codes of higher
order than that.

I posted a self-contained code:
https://gist.github.com/runiteking1/b0946026d2cad966db1e52c0a28a86c6

To see the error, comment out the second definition of one_patch (i.e.
lines 103 to 166). The error I get is

OpenGL.error.GLError: GLError(
err = 1281,
description = 'invalid value',
baseOperation = glMap2d,
pyArgs = (
GL_MAP2_VERTEX_3,
0,
1,
27,
9,

<OpenGL.arrays.lists.c_double_Array_3_Array_9_Array_9 object at
0x7fa4ecbbff80>,
),
cArgs = (
GL_MAP2_VERTEX_3,

cArguments = (

<OpenGL.arrays.lists.c_double_Array_3_Array_9_Array_9 object at

)
)

Does anybody know workarounds?

Best,
