* Bug 1501: Apply intersection tests for non-convex shapes to reject new CCW ↵Sven Göthel2024-02-133-26/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and non-circulcircle triangulation candidates in our Delaunay tessellator <https://jogamp.org/bugzilla//show_bug.cgi?id=1501#c6> The used Delaunay tessellation works well with (almost) convex shapes. In case e.g. a glyph gets to the extremes like 'M' in FreeMono or any other complex Chinese symbol - it may just simply happen that the new non-circumcircle triangle point crosses the inner (hope) or outer boundaries of the given polygon. Applying further constraint at Loop.cut() resolves most cases by rejecting the proposed CCW and non-circumcircle triangle candidate if its new two line-segments intersects with the original polygon. This results in mostly proper rendered Chinese fonts and also FreeMono is now readable - overal remaining bugs in Glyphs is low. +++ Of course, this intersection test is costly around >= O(log(n)*n) costs, practically adding a measured ~65% processing time. E.g. for FontView01 using FreeSerif.ttf - orig total took 1430.817638ms, per-glyph 0.2236ms, glyphs 6399 - fix total took 2377.337359ms, per-glyph 0.371517ms, glyphs 6399 Pure Glyph/Shape instantiation shows > 2x costs: 750 ms 100% convex (fake) 1875 ms 0% convex (fake) 1870 ms 13% convex 824/6399 +++ Hence it is desired to either (1) Manually mark a polygon non-convex to add described intersection test for accuracy. Also may be used to just drop the additional costs despite the lack of correctness. PROVIDED (2) Determine non-convex nature of a polygon with a and overall less expensive algorithm. If considerably cheaper, this could reduce O(log(n) * n) -> O(n) or even O(log n). Added convex/non-convex classification while ignoring off-curve points, but only ~13% of FreeSerif is pure convex, hence there is no benefit with this classification type. It might be desired to attempt other classes, i.e. being rendered in non-convex mode w/o intersection tests.

* Bug 1501: Graph Delaunay: Use default winding outer-boundary:=CCW and ↵Sven Göthel2024-02-122-9/+10
| | | | | | | | | | | inner-hole:=CW w/o using winding determination (might be incorrect) This simplifies our code further and it has been validated that our polygon shoelace-algo for area >= 0 ? CCW doesn't produce correct results with all curves. Hence rely on given winding depending on outer-boundary and inner-hole if CDTriangulator2D.FixedWindingRule == true (default and fixed). This also removes the more costly winding shoelace calculus, hence Outline ctor only sets dirtyWinding:=true w/o calculating the winding.

* Bug 1488 - Graph RegionRenderer Shader Mapping: Revert to IntObjectHashMap ↵Sven Göthel2024-01-221-64/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and throw exception on shaderKey collision Commit 6363ae5fb6975a6f2e7c1093ce81f25b699e3e61 changed RegionRenderer.useShaderProgram()'s shader mapping using a new ShaderKey instance. Such ShaderKey instance is created every time @ RegionRenderer.useShaderProgram() to retrieve the ShaderProgram from the HashMap<ShaderKey, Shader Program>. While this is most correct, creating the ShaderKey instance causes a lot of temp objects. ShaderKey also uses the optional colorTexSeq shader code for equality test in case of hash-collisions. Previous code simply ignored hash-collisions and used a 1:1 hashCode -> ShaderProgram mapping using our IntObjectHashMap. However, there was no test whether collision occur. +++ Solution would be either 1- Revert fully to the previous code just using an IntObjectHashMap, but throwing a RuntimeException in case of hashCode collisions. In case of a collisions, we would need to produce a better hashCode. This is possible, as the underlying data is fully internal .. etc. 2- Use the IntObjectHashMap as long there is no hashCode collision, then revert back to HashMap<ShaderKey, Shader Program>. +++ This patch implements variant (1), so far no exception has been thrown on multiple demos w/ and w/o diff color-textures.
* Graph Clipping: Use Frustum Clipping using AABBox -> Mv transformed Cube -> ↵Sven Göthel2024-01-202-27/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | well as to extract planes for float[] vec4-shader uniforms. commit 1040bed4ecc6f4598ea459f1073a9240583fc3c3 added AABBox -> Cube -> Frustum mapping (incomplete) and requires Frustum.Plane.set(..) by normal and point-on-plane for distance. Frustum.isOutside(Cube) has been added, testing all its 8-points similar to AABBox. Further all 6 Frustum.Plane shall be extracted to Vec4f and float[], the latter to pass the whole float[4*6] as a vec4[6] uniform array to the shader. +++ Constructor, setter and getter have been adjusted accordingly. Most of the loops have been unrolled. +++ Method names to query Frustum, i.e. 'is*Outside(<Type>)' have been reduced to 'isOutside(<Type>)' where <Type> uniquely indenticates the purpose. Hence only 'isSphereOutside()' is left over.
* Graph/GraphUI AA-Quality + SampleCount (shader): Push params down to ↵Sven Göthel2024-01-165-52/+89
| | | | | | | | | | | | | | | | | | RegionRenderer's RenderState usually rarely set from top of user API, reducing complexity. Discussion: Alternative was to pass AA-Quality same as SampleCount from the top (e.g. GraphUI Scene), however, this convolutes the API even more. Both parameter modify the resulting shader code in pass2 rendering (only). The used 'renderMode' is still maintained within the Region, since it contains more dynamic states individual to each Region instance (color-texture, ..). This despite 'renderMode' also changes the RenderState's shader program. In the end, it really doesn't matter and is a choice of frequency - the pipeline is usually rendering from on OpenGL rendering thread sequentially. AA-Quality and SampleCount simply usually don't change that often and are set only once.

* Graph Clipping: Add missing Modelview-Matrix (Mv) Multiplication / ConsiderationSven Göthel2024-01-092-0/+5

Add facility to program the texture-coordinates to either letter-box or scaled-up (and cut) true aspect-ratio.

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.

The 'com.jogamp.opengl.util.PMVMatrix' currently also used to feed in GLUniformData via the toolkit agnostic SyncAction and SyncBuffer shall also be split to a toolkit agnostic variant.
