Member Function Documentation

ComputePickingRay()

XII_ALWAYS_INLINE xiiResult xiiViewData::ComputePickingRay ( float fNormalizedScreenPosX, float fNormalizedScreenPosY, xiiVec3 & out_vRayStartPos, xiiVec3 & out_vRayDir, xiiCameraEye eye = xiiCameraEye::Left ) const

inline

Calculates the start position and direction (in world space) of the picking ray through the screen position in this view.

fNormalizedScreenPosX and fNormalizedScreenPosY are expected to be in [0; 1] range (normalized screen coordinates). If no ray can be computed, XII_FAILURE is returned.

ComputeScreenSpacePos()

XII_ALWAYS_INLINE xiiResult xiiViewData::ComputeScreenSpacePos ( const xiiVec3 & vWorldPos, xiiVec3 & out_vScreenPosNormalized, xiiCameraEye eye = xiiCameraEye::Left ) const

inline

Calculates the normalized screen-space coordinate ([0; 1] range) that the given world-space point projects to.

Returns XII_FAILURE, if the point could not be projected into screen-space.
