Detailed Description

Bit flags for specifying matrix options.

Only one option may be specified per enum, with all the specified options combined with bitwise-or |.

Most methods that take matrix flags only obey OSVR_MatrixOrderingFlags and OSVR_MatrixVectorFlags - the flags that affect memory order. The remaining flags are for use with projection matrix generation API methods.

Typedef Documentation

OSVR_MatrixVectorFlags

typedef enum OSVR_MatrixVectorFlags OSVR_MatrixVectorFlags

Flag bit controlling expected input to matrices.

(Related to OSVR_MatrixOrderingFlags - setting one to non-default results in an output change, but setting both to non-default results in effectively no change in the output. If this blows your mind, just ignore this aside and carry on.)

Enumeration Type Documentation

OSVR_MatrixOrderingFlags

enum OSVR_MatrixOrderingFlags

Flag bit controlling output memory order.

Enumerator
OSVR_MATRIX_COLMAJOR	Column-major memory order (default)
OSVR_MATRIX_ROWMAJOR	Row-major memory order.

OSVR_MatrixVectorFlags

enum OSVR_MatrixVectorFlags

Flag bit controlling expected input to matrices.

(Related to OSVR_MatrixOrderingFlags - setting one to non-default results in an output change, but setting both to non-default results in effectively no change in the output. If this blows your mind, just ignore this aside and carry on.)

Enumerator
OSVR_MATRIX_COLVECTORS	Matrix transforms column vectors (default)
OSVR_MATRIX_ROWVECTORS	Matrix transforms row vectors.

OSVR_ProjectionMatrixInputFlags

enum OSVR_ProjectionMatrixInputFlags

Flag bit to indicate coordinate system input to projection matrix.

Enumerator
OSVR_MATRIX_RHINPUT	Matrix takes vectors from a right-handed coordinate system (default)
OSVR_MATRIX_LHINPUT	Matrix takes vectors from a left-handed coordinate system.

OSVR_ProjectionMatrixZFlags

enum OSVR_ProjectionMatrixZFlags

Flag bit to indicate the desired post-projection Z value convention.

Enumerator
OSVR_MATRIX_SIGNEDZ	Matrix maps the near and far planes to signed Z values (in the range [-1, 1]) (default)
OSVR_MATRIX_UNSIGNEDZ	Matrix maps the near and far planes to unsigned Z values (in the range [0, 1])
