Methods
(static) writeOrthographicMatrixTo(out, left, right, bottom, top, near, far) → {Float32Array}
Writes an orthographic projection matrix into an existing output matrix.
This uses the same clip-space depth convention as `writePerspectiveMatrixTo`.
Parameters:
| Name | Type | Description |
|---|---|---|
out |
Float32Array | Output 4x4 matrix (length 16), that will receive the projection matrix. |
left |
number | Left plane. |
right |
number | Right plane. |
bottom |
number | Bottom plane. |
top |
number | Top plane. |
near |
number | Near clipping plane distance. |
far |
number | Far clipping plane distance. |
- Source:
Returns:
- The output matrix.
- Type
- Float32Array
(static) writePerspectiveMatrixTo(out, fieldOfViewRadians, aspectRatio, near, far) → {Float32Array}
Writes a perspective projection matrix into an existing output matrix.
Parameters:
| Name | Type | Description |
|---|---|---|
out |
Float32Array | Output 4x4 matrix (length 16), that will receive the projection matrix. |
fieldOfViewRadians |
number | Vertical field of view in radians. |
aspectRatio |
number | Viewport aspect ratio (width / height). |
near |
number | Near clipping plane distance (must be > 0). |
far |
number | Far clipping plane distance (must be > near). |
- Source:
Returns:
- The output matrix (out).
- Type
- Float32Array
(static) writeViewMatrixTo(out, position, rotation, scale) → {Float32Array}
Writes a view matrix (inverse of camera, TRS) into an existing output matrix.
Assumes camera local transform order matches Object3D:
local = T * (Rz * Ry * Rx) * S
view = inv(S) * inv(R) * inv(T)
Parameters:
| Name | Type | Description |
|---|---|---|
out |
Float32Array | Output 4x4 matrix (length 16), that will receive the view matrix. |
position |
Vector3 | Camera position. |
rotation |
Vector3 | Camera rotation in radians. |
scale |
Vector3 | Camera scale (must be non-zero on all axes). |
