depth maps not appearing correctly

[nickponline]

I'm successfully running instant-ngp and getting a good result however when I switch to Depth Map mode I just get plain white images, I've tried the other settings for Colorspace and Tonemap Curve but still get a white / off-white image. Is this just that there is no false coloring for the depth maps?

Hi there, the depth buffer isn't normalized to the range [0,1]. Rather, it's expressed in scene units, which is why it looks white. You can reduce the exposure slider (or press Shift+E a bunch of times) to bring it into visible range. Cheers!

Hi @Tom94, after capturing the depth map, I see that the values are between 0-255. How do I get the maximum depth I can divide the values with?

You can set the render mode to depth beforehand, just like in the GUI.

testbed.render_mode = ngp.Depth

Hi, I do this to render the depth map,but I just get the white / off-white image, how can I deal with it?

@Tom94 Hi, I set testbed.render_mode to ngp.Depth and use testbed.render to render and save depth image, but I just get the white / off-white image,how can I get right depth image?

Hi, how can I capturing the depth map? I see that the values are 0 after testbed.render(resolution[0], resolution[1], spp, True).

@zzy729425207 Hi，did you finally get the depth map to work? I'm having the same problem now.
