Hello,
I'm kinda running into a problem here using the glUniform functions. I
use the following piece of code to set 8 values in the fragment shader:
input_image = glGetUniformLocationARB(program, "input_image")
glUniform1ivARB(input_image, 8, array([0, 1, 2, 3, 4, 5, 6, 7], 'i'))
When I use that piece of code, I get the following error:
glUniform1ivARB(input_image, 2, array([0, 1, 2, 3, 4, 5, 6, 7], 'i'))
File "/Library/Python/2.5/site-packages/OpenGL/wrapper.py", line
1273, in __call__
return self.finalise()( *args, **named )
File "/Library/Python/2.5/site-packages/OpenGL/wrapper.py", line 543,
in wrapperCall
pyArgs = tuple( calculate_pyArgs( args ))
File "/Library/Python/2.5/site-packages/OpenGL/wrapper.py", line 328,
in calculate_pyArgs
yield converter(args[index], self, args)
File
"/Library/Python/2.5/site-packages/OpenGL/arrays/arrayhelpers.py", line
41, in asArraySize
incoming,
ValueError: ('Expected 1 item array, got 8 item array', array([0, 1, 2,
3, 4, 5, 6, 7]), <function asArraySize at 0x6d79f0>)
Now I don't really understand what I'm doing wrong. Passing only one
value works perfectly, but I'd rather pass the entire array at once
instead of passing every single value.
(Python version 2.5.4, PyOpenGL version 3.0.0c1)
Regards, Gijs
