Projecting points to camera about nvisii

Check this function https://github.com/owl-project/NVISII/blob/master/examples/21.ndds_export.py#L66 I think it does what you need.

How can I just project points onto the camera matrix? Because it seems that using those matrices I get wrong pixel position

[TontonTremblay]

        p_image = cam_proj_matrix * (cam_matrix * pos_m) 
        p_image = nvisii.vec2(p_image) / p_image.w
        p_image = p_image * nvisii.vec2(1,-1)
        p_image = (p_image + nvisii.vec2(1,1)) * 0.5

You need this for pixel location, is that helpful.
