Fields

colors_sh_degree_max: u32

$ 0 \sim 3 $

focal_length_x: f32

$ \text{fl}_x = \frac{\text{im}_x}{2 \tan\left(\frac{\text{fov}_x}{2}\right)} $

focal_length_y: f32

$ \text{fl}_y = \frac{\text{im}_y}{2 \tan\left(\frac{\text{fov}_y}{2}\right)} $

image_size_half_x: f32

$ \frac{\text{im}_x}{2} $

image_size_half_y: f32

$ \frac{\text{im}_y}{2} $

point_count: u32

$ p $

tile_count_x: i32

$ \frac{\text{im}_x}{\text{t}_x} $

$ \text{t}_x $ is the tile width.

tile_count_y: i32

$ \frac{\text{im}_y}{\text{t}_y} $

$ \text{t}_y $ is the tile height.

view_bound_x: f32

$ \tan\left(\frac{\text{fov}_x}{2}\right) \cdot (c_f + 1) $

$ c_f $ is FILTER_LOW_PASS.

view_bound_y: f32

$ \tan\left(\frac{\text{fov}_y}{2}\right) \cdot (c_f + 1) $

$ c_f $ is FILTER_LOW_PASS.

_padding_1: [u32; 2]

Padding.

view_position: [f32; 3]

$ V_p \in \mathbb{R}^3 $

It is the position in world space.

_padding_2: [u32; 1]

Padding.

view_transform: [[f32; 4]; 4]

$ M_v \in \mathbb{R}^{4 \times 4} = \begin{bmatrix} R_v & T_v \\ 0 & 1 \end{bmatrix} $

$ R_v \in \mathbb{R}^{3 \times 3} $ is the rotation from world space to view space.
