Render-border & crop-node 2d-cage manipulators where unreasonably
complicated to implement because there was no good way to define
the sub-region the manipulator was transforming in
(render border within the camera's frame for example).
Add matrix-space variable,
remove scale property from cage2d manipulator, use matrix instead.

Was doing this with property get/set but this made view operations
require refreshing manipulator properties.
Simplify by operating on properties in their own space.
Also disable clamping for now since it assumes pixel-space.
|
|
Missed check for non-camera view frame
|
|
Note there are issues clamping & updating,
will resolve as part of changes to cage2d widget.

Spotted by Ray aka LazyDodo, thanks!

Two main things here:
1. Replace all unsafe for #line directive characters into a single loop,
avoiding multiple iterations and multiple temporary strings created.
2. Don't merge token char by char but calculate start and end point and
then copy all substring at once.
This gives about 15% speedup of source processing time. At this point
(with all previous commits from today) we've shrinked down compiled
sources size from 108 MB down to ~5.5 MB and lowered processing time
from 4.5 sec down to 0.047 sec on my laptop running Linux (this was a
constant time which Blender will always spent first time loading kernel,
even if we've got compiled clbin).
|
|
Also split update flag into draw-steps,
since drawing 3D manipulators was tagging 2D as being refreshed.
|
|
Also minor cleanuup, assign new vars for manipulator group.

Was Cygwin workaround, no longer needed.
|
|
Add a safe version of normalize since all uses of normalize
did zero length checks, move this into a function.
Also avoid unnecessary conversion.
Gives minor speedup here (approx 3-5%).
|
|
Basically gather lines as-is during traversal, avoiding allocating
memory for all the lines in headers.
Brings additional performance improvement abut 20%.
|
|
The idea here is that it is possible to mark certain include statements
as "precompiled" which means all subsequent includes of that file will
be replaced with an empty string.
This is a way to deal with tricky include pattern happening in single
program OpenCL split kernel which was including bunch of headers about
10 times.
This brings preprocessing time from ~1sec to ~0.1sec on my laptop.
|
|
The idea is to re-use files which were already processed. Gives about 4x speedup
of processing time (~4.5sec vs 1.0sec) on my laptop for the whole OpenCL kernel.
For users it will mean lower delay before OpenCL rendering might start.

Keyframe handle vertices (the circles on the ends of the handles)
should always be larger than the central vertex. This brings back the
"outer" radius value from the old gluDisk(), and doubles it to get the
necessary diameter, to scale it properly.
TODO's:
- Get rid of all fills inside these circles
- Make the central vertex square-shaped again
|
|
* Outlines of keyframes were too thick and ugly
* Size differences between keyframe types was being swallowed
by the pixel-fudge factor, leaving colour as the only distinguishing
factor (bad!)

This changes the Cycles exporting and Cycles/Eevee UI code to support both
output material nodes, giving priority to the renderer native one. Still
missing is Eevee code to prefer the Eevee output node.

raw value to prety-printed one.
Note that new code allows to enable again the '1 million miles' tests.
|
|
This is still far from prefect, but yet much better than what we had so
far (more consistent with inheritent precision available in floats).
Note that this fixes some (currently commented out) units unittests, and
requires adjusting some others, will be done in next commit.

Clear instance in case creating creating new instance fails.
In practice this shouldn't happen,
but better not cause further errors if it does.
|
|
Changing lamp type for eg needs to create a new instance.
