Struct embree4_rs::geometry::UserGeometry

pub struct UserGeometry { /* private fields */ }

Implementations

impl UserGeometry

pub fn try_new<T>( device: &Device, data: &T, bounds_fn: unsafe extern "C" fn(args: *const RTCBoundsFunctionArguments), intersect_fn: unsafe extern "C" fn(args: *const RTCIntersectFunctionNArguments), occluded_fn: unsafe extern "C" fn(_args: *const RTCOccludedFunctionNArguments) ) -> Result<Self>

Creates a new UserGeometry object.

Arguments

• device - The Embree device.
• data - The user-defined data associated with the geometry.
• bounds_fn - The function pointer to the bounds function.
• intersect_fn - The function pointer to the intersect function.
• occluded_fn - The function pointer to the occluded function.

Returns

A Result containing the UserGeometry object if successful, or an anyhow::Error if an error occurred.
