Before we checked data types to ensure compatibility, but some nodes (e.g. the
math node) may be compatible despite a not apparently compatible data type.
We allow users to make any connection quickly this way.
The first in many NodeView improvements. Up until now, nodes have been forcibly
auto-arranged, which has worked as a reasonable stop-gap just so that all the
nodes are visible during testing/development. However this does not make a good
user experience.
We move the auto-arrange code to a manual function that can be used when the
user or program deems it necessary, and also abstract the node positions so that
the view can ultimately determine the exact amount of spacing (useful for
changing DPIs) or orientation, so users can direct the flow whichever way they
want.
This required various changes to various parts of the infrastructure (mostly
using paths to finding the "root project" of any given object throughout).
Now theoretically infinite projects can be opened and accounted for at any
given time.
Rather than the cumbersome and small "node connectors" (introduced a while ago
when nodes had more than one output), this is a more streamlined system of
connecting nodes (hold Ctrl and drag to connect)
Implemented the ability to copy/paste blocks/clips in the timeline. This did
require some large scale changes and reworking of the copy/paste system
introduced a few commits ago, but should be largely functional now.
Should address any XML parsing issues and allows for simpler, more maintainable
code. Should also address a crash that could occur when pasting nodes that had
inputs that weren't copied.
Previous iteration used some "magic code" that added clips automatically to the
timeline. This was functional but ultimately outside of the undo commands'
control meaning nodes could be infinitely added and abandoned. This makes the
add process part of the undo command which means it's all undoable as the user
would expect.
This was many changes that were largely fundamentally related. They included:
- More const modifiers to enforce read only node graphs
- Support for fragment and vertex shaders from the nodes
- Support for node code loaded externally (embedded into the binary)
- Fixed issue preventing two textures from being used in a shader
- Removed several unused functions and cleaned up code
- Fixed video media node misreading its matrix input
