I find the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License, mentioned in your code and README confusing. Normally those sort of licenses are reserved for content, such as images, databases etc, which makes sense for the library that ya'll have generated using this software.

However, it is unclear to me whether the intention is to prevent users from generating new images for commercial purposes using this software or whether the license applies to the code text itself. I completely respect you applying whatever license you feel is fair, but I'd like it to be easier to understand for the community.

Also, note that creative commons recommends against using their license for software.

Hi, I just tested this addon in blender 2.70 and 2.79b and 2.82, only succeed in 2.79b. Blender2.8 is very different from blender2.7, so can you update this add to blender2.8?

Dear there.

My system is apple mac m1,my blender is 3.6. after installing and enabling it, I have the following error, looking forward to your reply!

Traceback (most recent call last):

Can you include [a] screenshot[s] in your read me to better demonstrate what this add-on does? Are these images from blender?

I have error message when I render a light field like below:
KeyError" 'bpy_prop_collection[key]: key "Z" not found'.

Do you have any ideas about this problem?

Thanks?

May has forgot it?

There's an error in the function render_depth_and_disp_maps(..) in lightfield_simulator.py .
When the LF.focus_dist is set to 0, it results in the calculated disp becoming nan as it is divided by 0.
Better to perform a check before applying the formula, so that LF.focus_dist or LF.sensor_size are not set to zero.

@lightfield-benchmark, thanks for the great add-on!

I've been playing around with rendering light fields with generated from your add-on in Unity. In Unity I have a plane that represents the camera array (UV), and an plane that represents where the camera frustums converge (ST).

I'm a little unsure how to map the configuration data I get from this add-on to the ST plane. A few question.

• Is the focus_distance_m the distance from the center camera on the UV plane to convergence plane?
• Is the convergence plane visualized in blender?
• Is the convergence plane the same width and height as the camera array? If not, how would I figure out its dimensions?

Thanks in advance for your help.

I'd love to use this light-field plugin as a script within my own python packages. Unfortunately I am totally new to Blender.

Would it be possible to add a very small section to the readme.md to explain how this can be run via a python script (maybe even with a minimal example scene)? I think this would help others (and me) a lot in understanding better how this addon can be used programmatically.

I got this error in https://github.com/lightfield-analysis/blender-addon/blob/master/light_field_renderer/lightfield_simulator.py#L482.
Your depthmapscale default is float. Want we cast the product to int or round it for the reshape?

Hello,

I'm new to blender, so I apologize if this is obvious!

I'm able to activate light field tools, but I'm not finding the "misc" tab anywhere. What am I missing?

Thank you!
