divVerent	99aef33970	examples/blur: fix the blur filter example to be a real box blur. (#2000) ... Also add a note that this is not how games should implement a blur if avoidable. Krita's blur and the original blur: https://rm.cloudns.org/img/uploaded/29c0418f25bf56b802f746d2f269e215.png The original image and the new blur (Krita's): https://rm.cloudns.org/img/uploaded/bd04828baf6c01fcf7301a6672a4c406.png Note how Ebiten's blur has almost no vertical component. Note how after the change it looks basically like Krita's.	2022-02-24 03:15:52 +09:00
divVerent	62229e82a6	Pre-failing test for color interpolation during rendering. (#2001) ... Before #1996, this failed with: image_test.go:1997: At(1, 0): got: {64 64 128 255}, want: {0 128 128 255} The difference is: - Before, colors were interpolated in straight-color space: - Background: {0 0 255 255} - Vertex A: {255 0 0 0} - Vertex B: {0 255 0 255} - Interpolated: {128 128 0 128} - Premultiplied: {64 64 0 128} - Onto Background: {64 64 128 255} - After, colors are interpolated in premultiplied space: - Background: {0 0 255 255} - Vertex A: {255 0 0 0} - Vertex A premultiplied: {0 0 0 0} - Vertex B: {0 255 0 255} - Vertex B premultiplied: {0 255 0 255} - Interpolated: {0 128 0 128} - Onto Background: {0 128 128 255} This DIFFERS from the sample fragment shader, which returns the color as is (Kage allows vertex color values to be used for arbitrary purposes and interpolates independently): - Shader sample: - Background: {0 0 255 255} - Vertex A: {255 0 0 0} - Vertex B: {0 255 0 255} - Interpolated: {128 128 0 128} - Onto Background: {128 128 128 255} as the blend function is `GL_ONE` / `GL_ONE_MINUS_SRC_ALPHA`. This shader behavior is unchanged but has been documented by #1996.	2022-02-24 03:12:33 +09:00
divVerent	f2209a0b51	internal/atlas: optimization: send premultiplied alpha from vertex to fragment shader. (#1996) ... Note that this applies only to the builtin shaders - interface for Kage stays unchanged for compatibility. Minor compatibility delta: when interpolating alpha values, previous code has created nonsense values, such as, when interpolating from fully-transparent-black (0,0,0,0) to opaque-white (1,1,1,1), something like half-transparent-grey (0.25,0.25,0.25,0.5) where half-transparent-white (0.5,0.5,0.5,0.5) is used by the new code. I assume this is a strict improvement, however this may warrant some testing. Possible later improvement could be moving the premultiplication from fragment shader to CPU. Did not do this as it makes the code rather inconsistent of Kage vs built-in shader usage. Updates #1772	2022-02-24 02:27:50 +09:00

Hajime Hoshi	fcd4453e4f	ebiten: remove RunOnMainThread ... Unfortunately, there are several issues in RunOnMainThread: * RunOnMainThread cannot be portable: It is impossible to implement this correctly on mobiles. * RunOnMainThread doesn't make sense on mobiles: the rendering works on a different thread (goroutine) on mobiles. * RunOnMainThread can cause deadlocks very easily. Until we find a better solution, let's remove this. Closes #1945	2022-02-14 01:49:42 +09:00
