* PMVMatrix rewrite using Matrix4f, providing SyncMatrix4f* for GLUniformData; ↵Sven Gothel2023-04-072-38/+33
| | | | | | | | | | | | | | | | | Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*) Big Easter Cleanup - Net -214 lines of code, despite new classes. - GLUniformData buffer can be synced w/ underlying data via SyncAction/SyncBuffer, e.g. SyncMatrix4f + SyncMatrices4f - PMVMatrix rewrite using Matrix4f and providing SyncMatrix4f/Matrices4f to sync w/ GLUniformData - Additional SyncMatrix4f16 + SyncMatrices4f16 covering Matrix4f sync w/ GLUniformData w/o PMVMatrix - Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*) - Moved FloatUtil -> Matrix4f, kept a few basic matrix ops for ProjectFloat - Most, if not all, float[] and int[] should have been moved to proper classes - int[] -> Recti for viewport rectangle - Matrix4f and PMVMatrix is covered by math unit tests (as was FloatUtil before) -> save Passed all unit tests on AMD64 GNU/Linux

| | | | | | | | | GLRendererQuirks.GLSLBuggyDiscard to avoid overdraw of such regions. Historically we disabled `discard` due to an old NV tegra2 compiler bug, which caused the compiler to freeze. Today we no more seem to have this GLSL compiler issue, i.e. GLRendererQuirks.GLSLBuggyDiscard never gets set.

| | | | | | | | | 67a723477ecd818fbc5859fe20ee536a3b4efae5 (reverting and clarifying) All Graph ShaderPrograms used are owned by RegionRenderer, not RenderState nor [GL]Region*, hence [GL]Region* shall only nullify the resources but not destroy the shader currently in use. One RegionRenderer maybe used for multuple Regions.

* Graph Region: Address overflow issue using GL2ES3 integer indices (WIP...); ↵Sven Gothel2023-02-243-16/+128
| | | | | | | | | | | | | | | Ease GLArrayData* buffer growth. Using integer indices, i.e. GL_UNSIGNED_INT, requires us to pass a GLProfile 'hint' to the GLRegion ctor. Region.max_indices is computed in this regard and used in Region.addOutlineShape(). TODO: If exceeding max_indices, the code path needs some work. Buffer growth is eased via GLArrayData using its golden growth ratio and manually triggering growth before processing all triangles in Region.addOutlineShape(). +++ TextRegionUtil static drawText() won't clear passed Region anymore, caller has to do this if so intended.
* GLArrayData*: Shorten methods (*API Change*), use proper constructor and ↵Sven Gothel2023-02-243-35/+25
| | | | | | | | | | | | | finalize immutables, add growthFactor (default golden ratio 1.618), add getCapacity*() and printStats(..) The growthFactor becomes essential for better growth behavior and can be set via setGrowthFactor(). The other changes were merely to clean up the GLArrayData interface and its 4 implementations. Not great to change its API, but one name was misleading ['getComponentCount' -> 'getCompsPerEleme'], so overall .. readability is enhanced. Motivation for this change was the performance analysis and improvement of our Graph Curve Renderer.

* Graph: Fix Loop.initFromPolyline()'s Winding determination, document Winding ↵Sven Gothel2023-02-173-58/+88
| | | | | | | | | | | | | | | | | | | | | | | rules for OutlineShape and add get/setWinding in Outline Loop.initFromPolyline()'s Winding determination used a 3-point triangle-area method, which is insufficent for complex shapes like serif 'g' or 'æ'. Solved by using the whole area over the Outline shape. Note: Loop.initFromPolyline()'s Winding determination is used to convert the inner shape or holes to CW only. Therefor the outter bondary shapes must be CCW. This details has been documented within OutlineShape, anchor 'windingrules'. Since the conversion of 'CCW -> CW' for inner shapes or holes is covered, a safe user path would be to completely create CCW shapes. However, this has not been hardcoded and is left to the user. Impact: Fixes rendering serif 'g' or 'æ'. The enhanced unit test TestTextRendererNEWT01 produces snapshots for all fonts within FontSet01. While it shows proper rendering of the single Glyphs it exposes another Region/Curve Renderer bug, i.e. sort-of a Region overflow crossing over from the box-end to the start.

* FBObject: Fix depth- and stencil bit count selection for attachRenderbuffer(..);Sven Gothel2014-09-202-3/+3
| | | | | | | | | | | | | | | - Fix depth- and stencil bit count selection for attachRenderbuffer(..) - Add generic values: DEFAULT_BITS, REQUESTED_BITS, CHOSEN_BITS, MAXIMUM_BITS - Refactor depth- and stencil bit-count -> format into own method - Allow depth- and stencil bit-count select a higher bit-count if required (fix) - GLFBODrawable.FBOMODE_USE_DEPTH is deprecated, using GLCapabilities.[get|set]DepthBits(..) - It was an oversight to introduce the bit flag in the first place, since we should have used the capabilities depth bit-count - Graph Test: GLEventListenerButton shall use requested capabilities for FBO drawable.

This commit adds AABBox.mapToWindow(..) method, which correctly either uses 4 points of the bbox in 3d space (using center-z) or all 8-points and creating a new bounding box.

* Bug 801: Fix VBAA Distortions (VBO-size fractional delta) and AA (Sample ↵Sven Gothel2014-03-049-266/+419
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
