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) )
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.
Fix for Bug #16: When rotated at an angle, surfaces get increasingly transparent.
This also fixes the saturation, chroma, alpha + contrast effects, while completely breaking macroblocks :)
Fix for Bug #18: DISTORT effect: disappearing triangles
Fix for Bug 19: SWIRL effect: mess if Center out of Region.
remove the 'Color' vertex attribute.
Make the 'deform' effect continuous when 'center' point passes through (0,0) i.e. middle of the Object.
fix in vertex shader
Bugfix in vertex shader (vertices were shot into outer space if P==S, i.e. if center point was exactly equal to the vertex being computed)
Progress with Vertex3D
Important bugfix in the vertex shader: there was division by 0 in case Center point was on the edge of the Object, resulting in some vertices being shot into outer space.
- Javadoc for EffectNames- make Matrix effects consistent with the rest (center of effect as last parameter!)- bugfix for yesterday's bugfix (we only want to send 'EFFECT_REMOVED' messages if it was really the Application that called 'abortAll' and not when we are cleaning up everything)
Major push towards simplifying DistortedObject's public API.Beginning of work on VERTEX Effects - does not compile ATM!
