We want to be strict on software renderer tests and opaque tests, but give a decent margin for blending inaccuracy for the blended tests.

Sam Lantinga authored Nov 21, 2009

Of COURSE that trick wouldn't work on all renderers.  Fall back to something for now, hopefully figure out a better way to do this later.

If we have to, we can use vertical line and horizontal line textures for vertical and horizontal lines, and then create custom textures for diagonal lines and software render those.  It's terrible, but at least it would be pixel perfect.

Sam Lantinga authored Nov 21, 2009

This is terrible, but the OpenGL standard says that lines are half open, which means that one endpoint is not covered so adjoining lines don't overlap.  It also doesn't define which end is open, and indeed Mac OS X and Linux differ.  Mac OS X seems to leave the second endpoint open, but Linux uses the right-most endpoint for x major lines and the bottom-most endpoint for y major lines.

RenderReadPixels and RenderWritePixels functions work with back buffer now and all asynchronous operations are flushed before reading or writing to backbuffer. Thanks Sam for clarification of this.

My first OpenGL shader! Momma will be so proud! · 335b4597

Sam Lantinga authored Nov 21, 2009

This shader implements the software renderer mask semantics where the source pixel is multiplied by the color and alpha modulation values and then any pixel with non-zero alpha is fully opaque.

The OpenGL renderer on Mac OS X now passes all the automated render tests! :)

SDL_RenderReadPixels() needs to flush asynchronous operations before it reads. · fc3f393a

Sam Lantinga authored Nov 21, 2009

The semantics are that it reads the back buffer, and those pixels may not be available once SDL_RenderPresent() has happened.

Mike Gorchak to Sam · 0c1f40fa

Sam Lantinga authored Nov 19, 2009

Hello Sam!

You have reverted back my patches for OpenGL renderer :)

To reproduce an issue, compare graphics output while running these tests:

testdraw2 --renderer opengl --blend mask --cyclealpha
and
testdraw2 --renderer software --blend mask --cyclealpha

You will see, that software renderer output is different from opengl renderer output.

Thanks!
