Hi all,
I have a plugin derived from AxisOp class, draws a complex geometry in
OpenGL in AxisOp::draw_handle(ViewerContext*) function.
The geometry data is stored as class member variable (not mapping to knobs
in the panel), when nuke runs in multi-threading, draw_handle() can be
called but real_valid() sometimes returns false, which makes the geometry
data doesn't synchronise correctly, for example, I have a variable :
class MyPlugin : public AxisOp {
...
std::vector< float > myarray;
...
};
when real_valid() returns false, size of "myarray" is empty, if real_valid()
returns true, everything is fine.
I have tried to call:
validate( true );
or
force_validate( true );
inside build_handles() and draw_handle(), but neither of them works.
So, what can I do to make sure validate( true ) has been called and my data
synchronise correctly before entering draw_handle() ?
Does anyone encounter this problem before?
Thanks a lot,
Shing
