MR_RayOrigin_float

typedef struct MR_RayOrigin_float MR_RayOrigin_float

Generated from class MR::RayOrigin<float>. Supported MR_PassBy modes: MR_PassBy_Copy, MR_PassBy_Move (and MR_PassBy_DefaultArgument and MR_PassBy_NoObject if supported by the callee).

Function Documentation

MR_rayBoxIntersect_4_MR_Box3f()

MRC_API bool MR_rayBoxIntersect_4_MR_Box3f	(	const MR_Box3f *	box,
		const MR_Line3f *	line,
		float	t0,
		float	t1 )

Generated from function MR::rayBoxIntersect<float>. Parameter box can not be null. It is a single object. Parameter line can not be null. It is a single object.

MR_rayBoxIntersect_5()

MRC_API bool MR_rayBoxIntersect_5	(	const MR_Box3f *	box,
		const MR_RayOrigin_float *	rayOrigin,
		float *	t0,
		float *	t1,
		const MR_IntersectionPrecomputes_float *	prec )

finds intersection between the Ray and the Box. Precomputed values could be useful for several calls with the same direction, see "An Efficient and Robust Ray-Box Intersection Algorithm" at https://people.csail.mit.edu/amy/papers/box-jgt.pdf Generated from function MR::rayBoxIntersect<float>. Parameter box can not be null. It is a single object. Parameter rayOrigin can not be null. It is a single object. Parameter t0 can not be null. It is a single object. Parameter t1 can not be null. It is a single object. Parameter prec can not be null. It is a single object.

MR_RayOrigin_float_AssignFromAnother()

MRC_API MR_RayOrigin_float * MR_RayOrigin_float_AssignFromAnother	(	MR_RayOrigin_float *	_this,
		const MR_RayOrigin_float *	_other )

Generated from method MR::RayOrigin<float>::operator=. Parameter _this can not be null. It is a single object. Parameter _other can not be null. It is a single object. The reference to things referred to by the parameter _other (if any) might be preserved in this object. The returned pointer will never be null. It is non-owning, do NOT destroy it. When this function is called, this object will drop any object references it held previously.

MR_RayOrigin_float_Construct()

MRC_API MR_RayOrigin_float * MR_RayOrigin_float_Construct

(

const MR_Vector3f *

ro

)

Generated from constructor MR::RayOrigin<float>::RayOrigin. Parameter ro can not be null. It is a single object. The reference to the parameter ro might be preserved in the constructed object. Never returns null. Returns an instance allocated on the heap! Must call MR_RayOrigin_float_Destroy() to free it when you're done using it.

MR_RayOrigin_float_ConstructFromAnother()

MRC_API MR_RayOrigin_float * MR_RayOrigin_float_ConstructFromAnother

(

const MR_RayOrigin_float *

_other

)

Generated from constructor MR::RayOrigin<float>::RayOrigin. Parameter _other can not be null. It is a single object. The reference to things referred to by the parameter _other (if any) might be preserved in the constructed object. Never returns null. Returns an instance allocated on the heap! Must call MR_RayOrigin_float_Destroy() to free it when you're done using it.

MR_RayOrigin_float_Destroy()

MRC_API void MR_RayOrigin_float_Destroy

(

const MR_RayOrigin_float *

_this

)

Destroys a heap-allocated instance of MR_RayOrigin_float. Does nothing if the pointer is null.

MR_RayOrigin_float_DestroyArray()

MRC_API void MR_RayOrigin_float_DestroyArray

(

const MR_RayOrigin_float *

_this

)

Destroys a heap-allocated array of MR_RayOrigin_float. Does nothing if the pointer is null.

MR_RayOrigin_float_OffsetMutablePtr()

MRC_API MR_RayOrigin_float * MR_RayOrigin_float_OffsetMutablePtr	(	MR_RayOrigin_float *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element. The reference to the parameter ptr might be preserved in the return value.

MR_RayOrigin_float_OffsetPtr()

MRC_API const MR_RayOrigin_float * MR_RayOrigin_float_OffsetPtr	(	const MR_RayOrigin_float *	ptr,
		ptrdiff_t	i )

Offsets a pointer to an array element by i positions (not bytes). Use only if you're certain that the pointer points to an array element. The reference to the parameter ptr might be preserved in the return value.
