Fields

clip_from_world: Mat4

unjittered_clip_from_world: Mat4

world_from_clip: Mat4

world_from_view: Mat4

view_from_world: Mat4

clip_from_view: Mat4

Typically a column-major right-handed projection matrix, one of either:

Perspective (infinite reverse z)

f = 1 / tan(fov_y_radians / 2)

⎡ f / aspect  0   0     0 ⎤
⎢          0  f   0     0 ⎥
⎢          0  0   0  near ⎥
⎣          0  0  -1     0 ⎦

Orthographic

w = right - left
h = top - bottom
d = far - near
cw = -right - left
ch = -top - bottom

⎡ 2 / w      0      0   cw / w ⎤
⎢     0  2 / h      0   ch / h ⎥
⎢     0      0  1 / d  far / d ⎥
⎣     0      0      0        1 ⎦

clip_from_view[3][3] == 1.0 is the standard way to check if a projection is orthographic

Glam matrices are column major, so for example getting the near plane of a perspective projection is clip_from_view[3][2]

Custom projections are also possible however.

view_from_clip: Mat4

world_position: Vec3

exposure: f32

viewport: Vec4

main_pass_viewport: Vec4

frustum: [Vec4; 6]

6 world-space half spaces (normal: vec3, distance: f32) ordered left, right, top, bottom, near, far. The normal vectors point towards the interior of the frustum. A half space contains p if normal.dot(p) + distance > 0.

lod_view_world_position: Vec3

The world-space position of the camera used to resolve visibility ranges.

This is the position of the camera itself, unless this view isn’t associated with a camera, in which case it’s the position of the primary camera.

color_grading: ColorGradingUniform

mip_bias: f32

frame_count: u32
