How can i add LROC NAC data on Moon sphere.???

Textures are supported as images in equirectangular coordinates (longitude-latitude maps) to be placed in the inputs/maps/albedo folder and pointed at in the corresponding YML input configuration file as shown in example.yml

If the map is limited in a specified region, please set the limits field to the corresponding limits of the map in radians. Default limits are [-pi, pi] and [-pi/2, pi/2] for longitude and latitude respectively. See example below. This feature has NOT been tested thoroughly. let me know how it goes.

rend = abram.render('YOUR_FILE.YML')
rend.body.maps.albedo.limits = [LON_MIN, LON_MAX; LAT_MIN, LAT_MAX]

Thanks for getting back to me, Andre. I really like your work. It would be helpful if you could share some documentation or a tutorial on how to use abram appropriately. I’m especially interested in seeing what a lander like object would look at when it’s closely approaching the lunar poles, with different sun angles.
Also, I noticed that the LRO WAC global map is at 100 meters/pixel, but the NAC files are much sharper at 0.5 meters/pixel. I am curious to try using the NAC GeoTIFF files with abram.
Thank you

thanks, unfortunately documentation is WIP, you can play with the tutorial scripts as for now. abram is more addressed to far-to-mid range scenarios, but I'll add geoTiff reading support and a tutorial with an arbitrary landing trajectory for a close-range scenario.

@HinalbPatel23 a tutorial on a Moon landing scenario has been added to the repository. The rendering sequence should look like this. I hope this tutorial can help you for your application. I used SLDEM2015 displacement maps and the Apollo metric albedo maps restricted to a specific longitude/latitude region for this scenario. In your application, you will need to find the maps for the region you need.

Note: To run the script, you will need to download these maps from the link in the readme.txt.
