Material Compile Error: Symbol defined multiple times

[riccardomarin]

Hi, I am trying to run the example about materials and glass colors. However it rise a compilation error.

Here is the code:

import numpy as np
from plotoptix import TkOptiX
from plotoptix.materials import m_clear_glass, m_mirror, m_plastic  # predefined materials
from plotoptix.utils import map_to_colors  # map variable to matplotlib color map

n = 6
a = 8
s = a / n
xyz = np.mgrid[0:a:s, 0:a:s, 0:a:s].reshape(3,-1).T
rnd = np.random.uniform(0, 1, xyz.shape[0])

# most cubes with the standard material:
xyz_c_diffuse = xyz[((xyz[:,0] == 0) | (xyz[:,1] == 0) | (xyz[:,2] == 0)) & (rnd < 0.7)]
# the rest made of mirror walls:
xyz_c_mirror = xyz[((xyz[:,0] == 0) | (xyz[:,1] == 0) | (xyz[:,2] == 0)) & (rnd >= 0.7)]

# most particles made of glass:
xyz_p_glass = xyz[(xyz[:,0] > 0) & (xyz[:,1] > 0) & (xyz[:,2] > 0) & (rnd < 0.4)]
# some plastic-like particles:
xyz_p_plastic = xyz[(xyz[:,0] > 0) & (xyz[:,1] > 0) & (xyz[:,2] > 0) & (rnd > 0.9)]

optix = TkOptiX(start_now=False) # no need to open the window yet
optix.set_param(min_accumulation_step=4,     # set more accumulation frames
                max_accumulation_frames=500, # to get rid of the noise

If I exclude the "mat" parameter from the set_data() method, it runs.

Do you have any suggestions on this?

Thanks!

Hi Riccardo,

Thanks for reporting. I need to check includes in shaders code. The error message points to that part. Good that OptiX is now verbose on this kind of problems. I'll let you know, likely tomorrow.

[robertsulej]

Could you, please, let me know the plotoptix and nvidia driver versions you are running? I can't reproduce the problem on linux and windows, with 2070 and 1060 boards. Also the shader compilation looks right, however this problem was present in earlier linux release (one of the first after the transition to OptiX 7, I think).

[riccardomarin]

Sure. I am on Windows 10. plotoptix==0.10.1 GPU: RTX 2080 Ti Driver: 460.15 I have both Cuda 10.0 and 10.1.

[robertsulej]

Ok, thanks!

There is a potential reason: OptiX compilation cache is not invalidated correctly after updates done with pip. Please, try deleting the folder %LOCALAPPDATA%\NVIDIA\OptixCache. If this helps I'll find a way to remove old compiled shaders when updating plotoptix.

[riccardomarin]

Great, it works! :D 👍🏼

[robertsulej]

Super. Next release (this weekend I hope) will not make such problems.

[robertsulej]

OK, the fix is in place in the new release.
