don't save v_planes.exr about panoplane360

[sunset1995]

Exr file of v_planes stores the plane parameter in each pixel.
Pixel of a plane share the same plane parameter and [0,0,0] is the non-planar special case.

Can you check some statistic of your v_planes to ensure that the result is actually empty?
Below is the statistic for static/mp3d_model_results/demo.v_planes.exr.

>>> v_planes.shape
(352, 1024, 3)
>>> np.unique(v_planes.reshape(-1,3), axis=0)

You may also want to use the vis_planes.py to visualize the result.

I get the following result after starting the inference on demo.png - static/mp3d_model_results/demo.v_planes.exr and demo.h_planes.exr
But v_planes - the file size is 6 kb and in your example it is 120 kb

After rendering vis_planes.py , the walls are not displayed
