Hello,

3Dtree has been updated. Now autumn is animated. Removed hand-made classes of leaf geometry and mesh. Now example uses ready mesh prepared in Blender. Modified a little constants of the tree. Example looks nice. This is a benchmark of your video card, because leafs and branches are stand alone objects (QEntity). For example 5 years tree has ~ 900 objects. My Intel Pentium with Intel HD graphics normally paint only 5 years tree, 6 years tree starts to slow down.

And one more - now you can rotate the tree with the left mouse button.

Hi,

I fixed a little 3Dtree. Now branches positions are correct. And I know that not all leafs is visible (this is because leaf geometry is implemented as plain which renders only on one side).

Hello,

I guess that Qt3D has huge memory leaks.

You can check it on this example: https://github.com/igormironchik/3Dtree

It's 3D tree, that grows year by year.

By default tree will grow 5 years (5 minutes).

When tree grown you can restart tree. And here I delete all resources:

void

MainWindowPrivate::createTree()
{
if(m_tree)
{
for(constauto&e:m_rootEntity->childNodes())
e->deleteLater();
}
m_tree=newBranch(m_startPos,m_endPos,c_startBranchRadius,
true,m_rootEntity);
m_tree->setAge(0.0f);
m_tree->updatePosition();
m_tree->placeLeafs();
}

But a lot of memory are eaten.
