[GRASS-dev] [GRASS GIS] #3600: m.nviz.image doesn't produce any output

[Michael Barton]

Here is a question to the memory of the dev group. Does anyone know if m.nviz.image has *ever* worked for Mac or Windows? 

If it has, any idea when it last worked? We could do a diff of the last working code and the current code to see what has changed. 

If not, it may take considerable effort to make this work.

Trying to figure out an efficient way forward

Michael

    without buffer swapping because it has only one buffer. BUT, glGetError()
    still returns GL_INVALID_OPERATION according to
    https://urldefense.proofpoint.com/v2/url?u=https-3A__www.khronos.org_registry_OpenGL-2D&d=DwIGaQ&c=l45AxH-kUV29SRQusp9vYR0n1GycN4_2jInuKy6zbqQ&r=lk-7X7CEOMDN8GaGVhiDsuO6gEp1wbG6nfT1XEEEtR0&m=BQAjtkxyihbnoyMfjeRJrNPso08jamSBCdnDLkAxL3w&s=MMgJ_nuxOOyqQYovZ_chgzuhRPYj6z2kgBDetoMH3lo&e=
    Refpages/gl4/html/glReadBuffer.xhtml. Probably, that's why some Linux
    drivers and MacOS don't work at all.
