Generating more Pov-ray objects

Open StoicGilgamesh opened this issue 3 years ago • 1 comments

First of all Amazing work!

I am also working with transparent objects and came across this amazing work.

I was wondering, how can I generate more pov-ray objects, like you all did like the "object.inc" file?

Some insight would be appreciable.

Best Regards, Hrishikesh Gupta

Hi, thanks for the interests.

As mentioned in the paper "We constructed parametric 3D models for the first three cate- gories, and generated a large number of models using ran- dom parameters. For complex shapes, we constructed para- metric 3D models for basic shapes like sweeping-spheres and squashed surface of revolution (SOR) parts, and com- posed a larger number of models using these basic shapes. We generated 178K 3D models in total, with each model as- signed a random refractive index λ ∈ [1.3, 1.5]. ".

You can define some shape templates, and write a simple python script to modify the hyper-parameters.

However, I think this data generation process is not very accurate. You might check https://cseweb.ucsd.edu//~mkchandraker/pdf/wacv19_transparent.pdf for a more sophisticated data generation.

Hey @guanyingc how can I download the attenuation masks? Thanks.

Hi, please check the google drive links in https://github.com/guanyingc/TOM-Net#overview. image

Hey @guanyingc, thanks for the reply. However in download_objects.sh https://github.com/guanyingc/TOM-Net_Rendering/blob/bee00df08c7ee4497874ce7349e7958b77b73181/download_objects.sh#L3 it's referring to TOM-Net_Povray_Inc_Objects.tgz, which isn't available on Google Drive and also the website is down. Could you please let me know how I can access it? Also TOM-Net_Povray_Inc_Objects.tgz would contain the attenuation masks right? Thanks!

The attenuation masks are not in TOM-Net_Povray_Inc_Objects.tgz. This tgz file only contains povray object in .inc format.

The masks you want will be generated after the povray rendering.

TOM-Net_Povray_Inc_Objects.tgz can be downloaded in https://pan.baidu.com/s/1RLX5Po8ElceoqWJmg1_aBA?pwd=p3yz. Thanks.

Hey @guanyingc, thanks for the clarification. However, I'm unable to access the Baidu link from India... Could you please upload it on Google Drive? Many thanks and sorry for the troubles! Cheers!

Hi, the data link in the download script can be access now. http://www.visionlab.cs.hku.hk/data/TOM-Net/
