Member Data Documentation

gAllocMem

GE_STATIC_EXPORT void*(* OdGeContext::gAllocMem) (unsigned long size)

static

A function pointer to a user-defined memory allocation function for all new operations in the OdGe library.

Remarks

Allows the OdGe library to use the same memory manager as the user application.

Parameters

size	[in] Size in bytes to allocate.

Definition at line 104 of file GeGbl.h.

gErrorFunc

GE_STATIC_EXPORT void(* OdGeContext::gErrorFunc) (OdResult)

static

A function pointer to a user-defined error handler.

Remarks

By default, points to a function that does nothing but return.

Definition at line 74 of file GeGbl.h.

gFreeMem

GE_STATIC_EXPORT void(* OdGeContext::gFreeMem) (void *memBlock)

static

A function pointer to a user-defined memory allocation function for all delete operations in the OdGe library.

Remarks

Allows the OdGe library to use the same memory manager as the user application.

Parameters

memBlock

[in] Allocated memory block to be freed.

Definition at line 115 of file GeGbl.h.

gOrthoVector

GE_STATIC_EXPORT void(* OdGeContext::gOrthoVector) (const OdGeVector3d &vect, OdGeVector3d &orthoVector)

static

A function pointer to a user-defined function that returns orthoVector orthogonal to vect.

Remarks

By default, points to a function that computes orthoVector with the arbitrary axis algorithm:

        if ( (vect.x < 0.015625) && (vect.x < 0.015625)) {
          orthoVector.x = vect.z;
          orthoVector.y = 0.0;
          orthoVector.z = -vect.x;
        }
        else {
          orthoVector.x = -vect.y;
          orthoVector.y = vect.x;
          orthoVector.z = 0.0;
        }

Parameters

vect	[in] Vector.
orthoVector	[out] Receives the orthogonal vector.

gTol

GE_STATIC_EXPORT OdGeTol OdGeContext::gTol

static

Provides the global default OdGeTol tolerance object.

Remarks

gTol.equalPoint == 1e-10 gTolequalVector == 1.e-10.

Definition at line 60 of file GeGbl.h.

gZeroTol

GE_STATIC_EXPORT OdGeTol OdGeContext::gZeroTol

static

Provides the global 0.0 default OdGeTol tolerance object.

Remarks

gZeroTol.equalPoint == 0.0 and gZeroTol.equalVector == 1.e-10.
