* Bug 805: Graph/GraphUI TextureSequence Scale: Move ↵Sven Göthel2024-02-013-4/+6
| | | | | | | | | Region.COLORTEXTURE_LETTERBOX_RENDERING_BIT to TextureSequence and add enabling/disabling of aratio adjustment + letter-box back-color TextureSequence color-texture params fetched from Graph VBORegion* and fed into shader. This allows more flexibility in aspect-ratio adjustment as well as setting a clipping background color for the added letter-box space.

* Graph Clipping: Use Frustum Clipping using AABBox -> Mv transformed Cube -> ↵Sven Göthel2024-01-2012-24/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | Frustum mapping + GraphUI Support AABBox clipping naturally couldn't be transformed into 3D Model-View (Mv) Space, as it is axis aligned and only provided 2 points (min/max). Therefor we map the Group's AABBox to a 8-point Cube, perform the Mv-transformation and then produce the 6-plane Frustum. As before, we cull fully outside shapes within the Group's draw method and perform fragment clipping with same Frustum planes in the shader. With clipping enabled, the 3D z-axis getBounds() depth will be slightly increased for functional Frustum operation. This is also done for setFixedSize(Vec2f). The Frustum planes are copied to the Graph shader via float[4*6] -> uniform vec4 gcu_ClipFrustum[6]; // L, R, B, T, N, F each {n.x, n.y, n.z, d} +++ Concludes related work of below commits - 1040bed4ecc6f4598ea459f1073a9240583fc3c3 - 5cca51e32999a882e2a5f00cb45ecafc824ffd86

Misc: - Graph VBORegion2PVBAAES2: Drop unused FBO rescale - Move MIN/MAX QUALITY/SAMPLE from GraphUI Scene -> Graph Region +++ Quality -> Pass2 AA Quality - Drop quality field in region - Pass quality to GLRegion.draw(..) similar to sampleCount for dynamic shader and switch - TODO: Pass quality parameter in TextRegionUtil's functions Fix RegionRenderer Shader Mapping - Use ShaderKey class to properly implement the hash value and equals method - For this, TextureSequence.getTextureFragmentShaderHashID() has been added to provide actual shader-snippet for the equals function - All required criterias are included in the hash value and equals method Fix AABBox Clipping for Pass-2 AA - Clipping in pass2-AA must happen in pass2 on actual gcu_PMVMatrix01 (not ortho) +++ GraphUI GraphShape - Rename: [get,set]{->AA}Quality() GraphUI Scene - Rename: mark{All->}ShapesDirty(), set{AllShapes->}Sharpness(), set{AllShapes->AA}Quality() - Fix setSampleCount(..), i.e. markStatesDirty() not markShapesDirty() - Fix setAAQuality(), markShapesDirty() and markStatesDirty(): Use forAll(..) to traverse through all shapes and groups. GraphUI Group - Add setFixedSize() - Add setClipOnBox() - Document setRelayoutOnDirtyShapes(), isShapeDirty()
* Graph Clipping: Add missing Modelview-Matrix (Mv) Multiplication / ConsiderationSven Göthel2024-01-092-2/+2
| | | | | | - GLSL vertex shader sets smooth varying 'gcv_ClipBBoxCoord' w/ Mv multiplied vertex-coord - RegionRenderer.setClipBBox(AABBox) expects a pre-multiplied Mv AABBox covering an independent area, not per Shape/Region. - This works as expected with moving/scaling of each Shape/Region etc
* Graph Clipping: GLSL: Add `USE_AABBOX_CLIPPING`, i.e. clipping via AABBox ↵Sven Göthel2024-01-098-19/+50
| | | | | | | | | | | | | | | min/max vec3 as convenient using Graph/GraphUI produced AABBox USE_AABBOX_CLIPPING - Conditional compilation w/ macro 'USE_AABBOX_CLIPPING' - gcv_ClipBBoxCoord smooth varying setup in vertex shader - fragment shader clips via branch if( is_inside(gcv_ClipBBoxCoord, gcu_ClipBBox[0], gcu_ClipBBox[1]) < 0.5 ) { CLIP } - clipping via discard or alpha=0 in case of buggy-discard. Other optimization: - Drop gcv_ColorTexExt, fragment-shader uses gcu_ColorTexBBox[2] directly (flat) - Simplified gcv_ColorTexCoord smooth varying equation in vertex shader.

| | | | | | | | | | | | | | | | | | 'and'/'or' semantic (swapped); Add EPSILON in clip_coord(..) and add is_inside(..) function Complete overload vec2 and vec3 variants Fix 'and'/'or' semantic (swapped) - 'and' uses multiplication, i.e. all arguments must be > 0 (ideally 1) - 'or' uses addition, i.e. only one arguments must be > 0 (ideally 1) - both uses clamp [0..1] Add EPSILON in clip_coord(..) - Only 'coord > high+EPSILON' is outside Add is_inside(..) function - Similar to clip_coord(..) but returns float 0 or 1 instead of selecting color.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aspect-ratio, letter-boxed or zoomed (config) + Bug 1466 Fix color mixing Bug 1465: Region currently simply bloats a given texture to its region AABBox, which renders textures with the wrong aspect ratio. Add facility to program the texture-coordinates to either letter-box or scaled-up (and cut) true aspect-ratio. Default shall be zoom (scale-up and cut), but user shall be able to set a flag in the Region for letter-box. Have the shader clip texture coordinates properly, best w/o branching to soothe performance. See functions.glsl +++ Bug 1466: Current color mix: texture * color_channel * color_static is useless in GraphUI. color_static shall modulate the texture, which works. But in case of color_channel (attribute/varying) we want it to be mixed so it can become the more dominant color for e.g. a border. Desired is: color = vec4( mix( tex.rgb * gcu_ColorStatic.rgb, gcv_Color.rgb, gcv_Color.a ), mix( tex.a * gcu_ColorStatic.a, 1, gcv_Color.a) );

* Bug 801: Fix VBAA Distortions (VBO-size fractional delta) and AA (Sample ↵Sven Gothel2014-03-047-208/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fragment position and count) Inflating the FBO pixel-size of the region using a 'samples count' multiplier to the projected window bounding box allows controlling the AA distortion as well as defining the fragment position due to it's grid-fitting nature, see below. - Fix VBAA Distortions (FBO-size fractional delta) Inflated framebuffer exceeds 'box-size * sampleCount' since it must be the ceiling of the latter due to it's integer number nature. This difference either must reflect the texture-coords -or- the texture bounding vertices-box in the 2nd pass, otherwise a distorion will appear which is quite visible explicit w/ text. Using texture-coords is not suitable, due to floating point accuracy, hence this patch extends the texture bounding vertices-box about the ceiling delta. A comparible distortion existed with the previous implementation as well, since it used an arbitrary FBO-size and hence the magnification was not grid-fitting. Current implementation is grid-fitting, or at least matches the non-inflated grid, since it inflates the original window-size of the region about samples-count. - AA (Sample fragment position and count) Using a sample-count w/ a multiple of 2 (currently 2, 4 and 8 are properly implemented), based on the projected window bounding box will give the 2nd-pass fragment shader (AA) a fragment-postion in center of the sample pixels exposing one AA pixel. Hence we need to use the diagonal coords (NW, SW, ..) off by half a pixel to reach the 1st sample-pixel .. and 1.5 pixels to reach the 2nd .. and so forth.
