Make the WAVE effect 5D (extra parameter 'offset')
Add Static5D and Dynamic5D.
Improvements to comments.
Reflect the fact that we are no longer caching sine and cosine in the EffectNames comments.
swap the 2nd and the 3rd parameters in the WAVE effect and improve comments for the WAVE user API.
Switch off the pre-compulting of sin and cos in CPU as it turns out that those two are single-instruction functions on any modern GPU ( http://www.gamedev.net/topic/322422-number-of-gpu-cycles-for-cos-and-sin-functions/ - link form 2005 ! )
Improve the comment the WAVE effect.
Correct one more issue with computation of WAVE.
Correct one issue with incorrect shadows in WAVE when V.z <0 .
Now we can add up the WAVE effect to others with smooth shading! Remaining issues:
- when angle A < 0, the shades are wrong- sometimes (check with the 3D vertex & Fragment effects' app) we get black spots at seemingly random points. Looks like computational instability again.
Shades in the WAVE effect fully working, if the effect is the only one.
Remaining: combine the shades with other effects!
Shades of the WAVE effect (almost!) working.
small improvements in DISTORT
Better normals in DISTORT
Vertex positions fully 3D now. Remaining: normals!
Preparation to make the WAVE effect fully 3D
Adjustments for EffectQueueVertex.postprocess()
Improvements for WAVE
Beginnings of the WAVE effect.
Correct an important bug in the vertex shader.
b = 1/a if a!=0, 1 otherwise was incorrectly computed as b = 1.0 / (a+1.0-sign(a)). This, when 0<a<2^-24, suffers from 'round-off error': then a+1.0 = 1.0 (sic!) thus b = 1/0 !.
Correct way: b = 1.0 / ( a - (sign(a)-1.0) )
Fixes for fragment effects in Effects3D.
Fix for Bug #17: Regions of Fragment Effects migrate.
Fix is: don't send vertex position and the Fragment Effect region to the fragment shader already multiplied by the ModelView matrix (that introduces the imprecise interpolation because of the projection effect) but simply send both of them in local coords.
Remove the MACROBLOCK Effect altogether.
Finally fix the 'when rendering though an FBO, the other side of triangles is visible'
Fix the 1x1 case! Before it used to be impossible to create a DistortedBitmap just with 2 triangles!
