Search for fast drawing method with WPF
Measure FPS by writing drawing processing for each type of DrawType
Blog http://puni-o.hatenablog.com/entry/2018/04/11/135728
Place the control in the MainWindow of WPF and measure the drawing speed of that control.
Draw a lot of particles(short lines) with a pen whose color changes every frame (palette is 8 colors).
The movement of Particles and the creation of pallet are the same.
Change the drawing part only for each DrawType and look at FPS.
DrawType is defined as enum
It does not draw.
I think this is the maximum FPS.
For checking how late it is when Freezable is not Freeze.
Drawing Particles one at a time in DrawingContext.DrawLine.
Almost the same as NotFreeze.
Check the speed when Freeze.
Particle's drawing is done by DrawingContext.DrawGeometry in palette unit.
Drawing in the DrawingGroup and drawing it in DrawingContext.DrawDrawing collectively.
Using WriteableBitmap (Since it is troublesome to manipulate WriteableBitmap directly, I use WriteableBitmapEx).
Drawing with Direct2D using SharpDX and D2dControl.
CPU : Core i7-6700 , GPU : GeForce GTX 1070
(I do not know if the measurement method is fair)
| DrawType | 10000 particles FPS(roughly) | 50000 |
|---|---|---|
| NotFreeze | very slow | |
| Freeze | 50 fps | 10 fps |
| Grouping | 90 fps | 16 fps |
| BackingStore | 10 fps | very slow |
| WriteableBitmap | 120 fps | 60 fps |
| Direct2D | - | 20 fps |
Using WriteableBitmap is the fastest.
But WriteableBitmap(Ex) has poor functions.(the coordinate system is not floating point)
Please tell me a nice idea :)
