about rot #38

Closed shaonian123daly closed 3 months ago

你好,作者!我想请问下为什么在计算rot_out时,不用被注释掉的部分,而仅采用归一化

rot_out = torch.ones((B,x.shape[1],4)).to(x.device)

rot_out = self.rotation_head(x)

rot_out = torch.nn.functional.normalize(rot_out, dim=-1)

以及在计算 color_out时,为什么把x和rgb_vr一起cat起来,color_out不是在计算高斯分支的color吗,希望作者能解答一下,万分感谢

你好,这是设置都是基于实验结果,因为我们发现固定rotation和学习rotation效果差不多;把x和rgb_vr一起cat起来最后的性能会稍微好一点。
