So, to know the contents of B, you need to look at the 3rd column. If 4 Nodes are created named A, B, C, D the picture above is saying: In SSE2 SIMD builds, ArrayVector3 packs 4 vectors together (because ARRAY_PACKED_REALS = 4). We fill the memory with valid values after releasing memory slots to prevent NaNs & INFs as some architectures are slowed down when such floating point special is present but it is possible that some of them slip through (or it is also possible a neighbour Entity actually contains an infinite extent, for example). there are only 3 entities in the entire scene) it could contain complete garbage even NaNs. Note that if, for example, the 4th element (in this case it reads (0, 0, 0)) is an empty slot (i.e. M_chunkBase you should've guessed by now contains ZZ ZZ M_chunkBase contains four YY YY, ours is the second one (starting from the right) M_chunkBase contains four XX XX which are read right to left. We're reading the 3rd column because mIndex is 1 if mIndex were 3 we would have to read the 1st column. Here the debugger is telling us that the center of the Aabb in local space is at (100 100 100). Notice we satisfy a very important property: all of our pointers are aligned to 16 bytes.ĪrrayVector3, ArrayQuaternion and ArrayMatrix4 require a bit more of work when watching them through the debugger: This layout may be a bit hard to grasp at first, but it's quite easy once you get used to it. mIndex is used to determine where our data really is. When we go to the 5th, the pointers increment by 4 elements. The Transform of the first 4 Nodes will have exactly the same pointers the only difference is the content of mIndex. When 9 consecutive Nodes are created, if we take a look at mParents pointers, we would notice that first 4 point to the same memory location: Hence to know which mParents belongs to us, we have to look at mParents. The following is part of the declaration of Transform (which is used by Nodes): Otherwise it may only show you the first element alone. Note that in the watch window adding a comma followed by a number forces MSVC debugger to interpret the variable as an array. In the picture above, we can now inspect the parent node of our object.

In this case our parent is in mObjectData.mParents because mIndex = 1 In this case, ObjectData::mParents contains the parent nodes of all four MovableObject. The macro ARRAY_PACKED_REALS is defined as 4 for this build to let application know how many floats are being packed together. Because this was taken from a SSE2 (single precision) build, its value can range between 0 and 3 (inclusive). The most important element in this picture is mIndex. The following screenshot shows it's contents: MovableObjects store their SoA data in MovableObject::mObjectData. Nevertheless, debugging SSE builds directly isn't that difficult. That is from the Autodesk knowledge graph.However our setup is actually quite different from other engines approaches, as 4 Vector3s are packed like the following in memory: Vectors [0 4)ĭebugging SIMD builds can be quite counterintuitive at first, in which case defining OGRE_USE_SIMD 0 and recompiling will force Ogre to use the C version of ArrayMath, and hence only pack 1 Vector3 per ArrayVector3.

Select the desired Elements, then press the Detach button. Select the collapsed/attached Editable Mesh or Editable Poly object, then go to the Command Panel > Modify > Editable Mesh/Editable Poly > Sub-object: Elements button.To “break up” and separate a collapsed (non-Boolean) object back into its component parts: (Note: to detach Boolean object operands after merging, see the “Operands” information in the 3ds Max Help file.) See the 3ds Max Help file on Boolean Operations.If dealing with in excess of 1,000 objects or so, select only 100-200 at a time to attach or collapse, then continue with the next “batch” of objects until all have been combined. Note: attaching or collapsing large numbers of objects (500 or more) may take considerable time. Select all objects you want to collapse into a single object, then go to the Command Panel > Utilities > Collapse, select the Collapse options, then click on Collapse Selected.Use the Collapse Utility to collapse multiple selected objects into a single object: This will allow you to pick single or multiple objects to attach into a single object. With a single Editable Mesh or Editable Poly object selected, go to the Command Panel > Modify > Edit Geometry > Attach button.Use the Attach button to permanently fuse or join objects: There are multiple ways to do this in 3ds Max:
