Methods

`Static`createLineIndicesForPoints

createLineIndicesForPoints(pointsDataFloat32: Float32Array): Uint16Array
Create a line index array for the given points
Parameters
- pointsDataFloat32: Float32Array
  The points to create the line indices for
Returns Uint16Array
- Defined in Extensions/RenderEngine/RenderEngineUtility.ts:110

`Static`fromVec3

fromVec3(vec3: Float32Array): Vector3
Transform the vec3 to a core Vector3 type
Parameters
- vec3: Float32Array
Returns Vector3
- Defined in Extensions/RenderEngine/RenderEngineUtility.ts:177

`Static`rayPlaneIntersection

rayPlaneIntersection(
    rayOrigin: Vector3,
    rayDir: Vector3,
    planeNormal: Vector3,
    planePoint: Vector3,
): null | Vector3
Finds intersection of a ray with a plane. Parameters are expected to be in the same coordinate space.
Parameters
- rayOrigin: Vector3
  The origin of the ray.
- rayDir: Vector3
  The direction of the ray.
- planeNormal: Vector3
  The normal of the plane.
- planePoint: Vector3
  A point on the plane.
Returns null | Vector3
The intersection point or null if no intersection.

`Static`toFloat32Attay

toFloat32Attay(points: Vector2[]): Float32Array
Convert a Vector2 array into a Float32Array
Parameters
- points: Vector2[]
  The Vector2 array to convert (each point is 3 floats: x, y, 0).
Returns Float32Array

`Static`toModelMatrix

toModelMatrix(transform: Transform): Float32Array
Convert the Transform into a model matrix
Parameters
- transform: Transform
Returns Float32Array
- Defined in Extensions/RenderEngine/RenderEngineUtility.ts:11

`Static`toVec3

toVec3(vector: Vector3): Float32Array
Transform the core Vector3 into the web-gpu Vec3
Parameters
- vector: Vector3
Returns Float32Array
