- changed VoxelTree to support destructive and non-destructive mode
- added protocol packet headers to differentiate
- added new UI to switch modes
- default mode now, non-destructive.
- Updated Voxel Server to support non-res-in version of voxel distribution
- Updated agent data to allow client to send desired res-in and color state
- added menu items to client debug menu to toggle wantResIn and wantColor
- Fixed a bug in updateNodeInArraysAsFullVBO() that caused blended strategy
to not work properly.
- Implement strategy to usually update only the portion of the VBOs that
have changed, unless nodes have been removed, and then update the full
VBO. This siginificantly improves treeToArrays() performance
- Still to do implement partial strategy for copy buffers and update GPU
- Introduced concept of sometimes only updating the new/changed part of the VBO
while other times updating the full VBO. This allows us to get the speed
advantage of only partial VBO updates when nodes haven't been removed
- Some debugging output related to _alwaysRenderFullVBO
- added cleanupRemovedVoxels() which actually deletes the nodes that were
previously removed (fixes a memory leak!!)
- don't recurse down trees that are fully INSIDE of the view frustum, because those nodes
are guaranteed to also be INSIDE
- changes to extraData of the recurse operation to make this possible
- adding debug stats to track how many nodes are inside, outside, intersect
- change call to removeOutOfView() to not call if last elapsed time has not
yet passed since last call (similar to treeToArrays() logic)
- make octalCode and children members private
- add public getters for accessing these private members
- change constructor to require an OctalCode for all non-roots
- default constructor constructs a rootNode
- make primary access for deleting, adding, and accessing children through public methods that do bookkeeping
- calculate AABox on voxel creation so that we don't need to do all the math when we deal with voxels
- added methods on VoxelNode for common items like getCorner(), getCenter(), getLevel(), etc
- fixing some cases where TREE_SCALE was not using constant in prep for making TREE_SCALE larger
- added createLine() to VoxelTree
- added axis lines made of voxels to scene
- added corner points made of voxels to scene
