normals definition #28

Closed HeidiCheng closed 5 years ago

HeidiCheng commented 5 years ago

I have printed the values of normals' ground truth, and got the results that they are in the range of 0-100. May I ask about how to get the value? Is it scale from RGB or something else? Thank you!

Could you clarify which normal file(s) are you referring to?

Hi, we are using the 2.5D normal map in marrnet2.py and taking it from batch['normal']. May I also ask about how to obtain the 2.5D normal map from Shapenet object, we are not sure about the axis definition for the normal map. Thank you! Sincerely, Heidi

Regarding the range, we have applied an amplifying factor of 100 to the 2.5D maps, https://github.com/xiumingzhang/GenRe-ShapeHD/blob/b68e54d74dcceb5b3ba8b9846c210d10c70a1675/models/marrnetbase.py#L17 although this may be optional and unimportant.

We recommend using the camera's local coordinate system, although using the world coordinate system or any other frame may also work.
