Trying to generate 8K hdr images

[Junrongh]

Dear author,

Thanks for releasing these fantastic code. I tried to generate a 8K hdr image with your repo but found some issue. I changed the input h=512 w=1024 into h=1024 w=2048 in this file https://github.com/FrozenBurning/Text2Light/blob/master/text2light.py#L74

The generated holistic image is good, since these parameters will not affect this file. However, the [2048x1024] ldr file has some problem(I resized it manually for uploading)

It seems that the spe coordinate should be changed with the input width and height. I'm not so sure what shoud be adjusted. Could you please look into it?

The command line I used is python text2light.py -rg logs/global_sampler_clip -rl logs/local_sampler_outdoor --outdir ./generated_panorama --text "Beijing afternoon 4 pm" --clip clip_emb.npy --sritmo ./logs/sritmo.pth --sr_factor 4

Thank you!

Best wishes

To generate 8K HDR, instead of modifying h, w, you need to change the input parameter as --sr_factor 8, which directly upscale $512\times1024$ to $4096\times8192$.

So the model you trained is fixed to 512x1024?
