T=1初始化不透明度应该放到遍历高斯外边？

class Rasterizer:
    ...
    def render(
        self, point_list, W, H, points_xy_image, features, conic_opacity, bg_color
    ):
        ....
        # loop pixel
        for i in range(H):
            for j in range(W):
                # loop gaussian
                for idx in point_list:
                    # init helper variables, transmirrance
                    T = 1
                    ...
                    test_T = T * (1 - alpha)
                    if test_T < 0.0001:
                        break

                    # Eq. (3) from 3D Gaussian splatting paper.
                    color = features[idx]
                    for ch in range(3):
                        C[ch] += color[ch] * alpha * T

                    T = test_T

                # get final color
                for ch in range(3):
                    out_color[j, i, ch] = C[ch] + T * bg_color[ch]

        return out_color

对的，我觉得应该就是写错了（另外transmittance也笔误了
