Mesh Rasterisation taking unexpectedly long time
Hey folks! I want to rasterize a mesh and get pix_to_face and zbuf outputs. But the rasterization call is taking unexpectedly long time to complete.
I am trying to rasterize a (5368, 7152) sized image of 6M faces mesh.
The average time for a rasterization call is 7s. I don't know if this is the expected behaviour with pytorch3d since other libraries take way less time.
I am using the pytorch3d.renderer.mesh.rasterizer.MeshRasterizer class.
Raster settings
'image_size': (5368, 7152),
'blur_radius': 0.0,
'faces_per_pixel': 1,
'bin_size': None,
'max_faces_per_bin': None,
'perspective_correct': None,
'cull_backfaces': True,
'clip_barycentric_coords': False,
'cull_to_frustum': True,
'z_clip_value': 1.0,
Gpu specs:
Tesla T4, Cuda 11.6, with 16Gb of gpu ram
It would be really helpful if someone can point me to something I am doing incorrectly.
What other libraries are you comparing with, and how long do they take?
If you aren't relying on the rasterisation itself being differentiable, you could use MeshRasterizerOpenGL.

Sorry to bother, but could you refer me to a link or document on how to properly install necessary dependencies for MeshRasterizerOpenGL to work?
