◆ copy()

void Ogre::ObjectData::copy ( const ObjectData & inCopy )

inline

Copies all the scalar data from the parameter into this.

Remarks: A normal "=" operator, or an assignment constructor Transform( Transform & ) wouldn't work. This is because ArrayVector3 & co. would try to copy all the packed values, while we just want the scalar ones.

Furthermore, it would be confusing, because it would be not clear whether those two options should memcpy memory, or rebase the pointers, hence explicit functions are much preferred. @See rebasePtrs

Note that we do NOT copy the mIndex member.

Member Data Documentation

◆ mDistanceToCamera

RealAsUint* RESTRICT_ALIAS Ogre::ObjectData::mDistanceToCamera

Ours is mDistanceToCamera[mIndex].

It is the distance to camera. Value can be negative to account for radius (i.e. when the camera is "inside" the bounds of the object)

Referenced by advanceFrustumPack(), advancePack(), and copy().

◆ mIndex

unsigned char Ogre::ObjectData::mIndex

Which of the packed values is ours. Value in range [0; 4) for SSE2.

Referenced by copy().

◆ mLightMask

uint32* RESTRICT_ALIAS Ogre::ObjectData::mLightMask

The light mask defined for this movable.

This will be taken into consideration when deciding which light should affect this movable

Remarks: Since Lights object don't use this value, we reserve the value to either 0xffffffff or 0; using 0 to avoid adding null mOwner pointers to vectors (due to the SoA nature of working 4 items at a time, even if we just have 2 or 3)

Referenced by advanceCullLightPack(), advanceLightPack(), advancePack(), and copy().

◆ mLocalAabb

ArrayAabb* RESTRICT_ALIAS Ogre::ObjectData::mLocalAabb

Bounding box in local space.

It's argueable whether it should be like this, or pointer to a shared aabb (i.e. mesh aabb) to save RAM at the cost of another level of indirection, and converting AoS to SoA, but it's more convenient for SIMD processing to store each local aabb in the movable object (maximize throughput).

Referenced by advanceBoundsPack(), advancePack(), and copy().

◆ mLocalRadius

Real* RESTRICT_ALIAS Ogre::ObjectData::mLocalRadius

@See mLocalAabb

Remarks: Its center is at mLocalAabb's center, not at the position or origin

Referenced by advanceBoundsPack(), advancePack(), and copy().

◆ mOwner

MovableObject** Ogre::ObjectData::mOwner

The movable object that owns this ObjectData. Ours is mOwner[mIndex].

Referenced by advanceBoundsPack(), advanceCullLightPack(), advanceFrustumPack(), advanceLightPack(), advanceLodPack(), advancePack(), and copy().

◆ mParents

Node** Ogre::ObjectData::mParents

Holds the pointers to each parent. Ours is mParents[mIndex].

Referenced by advanceBoundsPack(), advancePack(), and copy().

◆ mQueryFlags

uint32* RESTRICT_ALIAS Ogre::ObjectData::mQueryFlags

Flags determining whether this object is included / excluded from scene queries.

Referenced by advancePack(), and copy().

◆ mUpperDistance

Real* Ogre::ObjectData::mUpperDistance[2]

Upper distance to still render. Ours is mUpperDistance[mIndex].

Referenced by ObjectData(), advanceFrustumPack(), advancePack(), and copy().

◆ mVisibilityFlags

uint32* RESTRICT_ALIAS Ogre::ObjectData::mVisibilityFlags

Flags determining whether this object is visible (compared to SceneManager mask)

Referenced by advanceCullLightPack(), advanceDirtyInstanceMgr(), advanceFrustumPack(), advanceLightPack(), advancePack(), and copy().

◆ mWorldAabb

ArrayAabb* RESTRICT_ALIAS Ogre::ObjectData::mWorldAabb

Bounding box in world space.

Referenced by advanceBoundsPack(), advanceCullLightPack(), advanceDirtyInstanceMgr(), advanceFrustumPack(), advanceLightPack(), advanceLodPack(), advancePack(), and copy().

◆ mWorldRadius

Real* RESTRICT_ALIAS Ogre::ObjectData::mWorldRadius

Ours is mWorldRadius[mIndex].

It is the local radius transformed by scale An ArraySphere out of mWorldAabb & WorldRadius for computations

Remarks: Its center is at mWorldAabb's, not at the derived position
