about new observation rendering

Hi,I want to render all the resulting images with a fixed camera, Here is my code, i just change the parameters about the camera

# lights is the fixed camera
    if lights is not None:
        # Set up rasterization configuration
        tanfovx = math.tan(lights[0].FoVx * 0.5)
        tanfovy = math.tan(lights[0].FoVy * 0.5)

        raster_settings = GaussianRasterizationSettings(
            image_height=int(lights[0].height),# change
            image_width=int(lights[0].width),# change
            tanfovx=tanfovx,   # change
            tanfovy=tanfovy,
            bg=bg_color,
            scale_modifier=scaling_modifier,
            viewmatrix=lights[0].viewmatrix,# change
            projmatrix=lights[0].projmatrix,# change
            sh_degree=pc.active_sh_degree,
            campos=lights[0].position,# change
            prefiltered=False,
            debug=pipe.debug
        )

    else:
        # Set up rasterization configuration
        tanfovx = math.tan(viewpoint_camera.FoVx * 0.5)
        tanfovy = math.tan(viewpoint_camera.FoVy * 0.5)

        raster_settings = GaussianRasterizationSettings(
            image_height=int(viewpoint_camera.image_height),
            image_width=int(viewpoint_camera.image_width),
            tanfovx=tanfovx,
            tanfovy=tanfovy,
            bg=bg_color,
            scale_modifier=scaling_modifier,
            viewmatrix=viewpoint_camera.world_view_transform,
            projmatrix=viewpoint_camera.full_proj_transform,
            sh_degree=pc.active_sh_degree,
            campos=viewpoint_camera.camera_center,
            prefiltered=False,
            debug=pipe.debug
        )

    rasterizer = GaussianRasterizer(raster_settings=raster_settings)

and i got some missing in results

could you tell me how to deal with it?

Hi, one solution is to use the lookat camera. I've attached the code for you to look over. You can set the novel_view_vis flag to be True to enable this function. ZJUMoCapRefine_lookat_camera.py.zip

Thanks a lot! I will try it
