glDrawPixels possible?

[ant]

Is it possible to use glDrawPixels from a newLISP script? I want to display an image I've constructed in an array of RGB values.

If it is possible, could you point me to the documentation or an example?

If it isn't possible, am I trying to do something newLISP is not designed for?

Here is an example how to import functions from OpenGL:
http://www.newlisp.org/syntax.cgi?downl ... mo-lsp.txt

It does not contain the glPixelDraw import, but shows how to import other functions and how to setup a window to draw in.

For the data in const GLvoid * data, you would use a string buffer produced with the 'pack' function
from the data points. Depending on the data type specified in GLenum type, you would use the correct
formatting character in 'pack'.

Hi Lutz, Thanks for the info. I'm trying it now but I haven't succeeded in getting anything on the screen yet. I'll keep at it. Ant
