Hit test a ray against the mesh with specified vertex and index buffer.
Namespace: Ab4d.SharpEngine.UtilitiesAssembly: Ab4d.SharpEngine (in Ab4d.SharpEngine.dll) Version: 2.0.8956+4c7684e186ca1be74e7a284fbe739d9a1b843d3c
Syntax public static RayHitTestResult? HitTest(
in Ray? localRay,
PositionNormalTextureVertex[]? vertexBufferArray,
int[]? indexBufferArray,
bool hitOnlyFrontFacingTriangles,
int startTriangleIndex,
bool getOnlyNextHitTest
)
Parameters
- localRay Ray
- ray transformed to local coordinate system
- vertexBufferArray PositionNormalTextureVertex
- vertex buffer as array of PositionNormalTexture
- indexBufferArray Int32
- index buffer
- hitOnlyFrontFacingTriangles Boolean
- When true then only triangles that have normals (calculated from triangle positions) oriented in the opposite direction as the ray are returned (because ray is usually created from the camera's position this returns only triangles that are facing the camera).
- startTriangleIndex Int32
- index of the triangle where the hit testing will begin - triangle indice index is get by multiplying this number by 3
- getOnlyNextHitTest Boolean
- when true, then the next hit result is returned; when false all hit results are get and only the closest to the ray origin is returned.
Return Value
RayHitTestResultDXRayHitTestResult when ray hits the mesh otherwise null is returned
